Abstract

Background Premenstrual syndrome (PMS) has a high prevalence among women of reproductive ages but despite its high prevalence, it has no determined and absolute treatment, so far. So, the aim of the present study was to compare the effect Pimpinella Anisum (Anise) with placebo on the intensity of the symptoms of PMS. Methods The present study was a randomized double-blind controlled clinical trial. College students who were suffering from PMS and had the inclusion criteria were selected and randomly assigned into two groups of intervention (Anise) and control (placebo). Participants in the intervention group, received 110 mg capsules of Anise three times day (a total dose of 330 mg per day); the control group received similar capsules with the same dosing that contained starch. Consumption of the capsules was started 7 days before the start of the menstruation and continued until 3 days after, which was a total of 10 days during two consecutive menstruation cycles. The intensity of the symptoms of premenstrual syndrome was measured using Premenstrual Symptoms Screening Tool (PSST). To compare the intensity of the symptoms between the two study groups, generalized estimating equation statistical method was used. Results Eventually, sixty-seven 18–35 year old college students who were suffering from premenstrual syndrome were enrolled in the study. Comparing the mean score of the intensity of the syndrome between the two groups after the first and the second menstruation cycles showed a decrease in the intervention group to 13.9 (p-value<0.001; 95% CI: 16.5,−11.4) and 9.8 (p-value<0.001; 95% CI: 12.4,−7.3), respectively. Conclusion Results of the study showed that, in general, Anise was effective in decreasing the symptoms of premenstrual syndrome in comparison to placebo.

Herbal medicine and nutritional supplements are suggested to treat premenstrual somatic and psycho‐behavioural symptoms in clinical guidelines; nonetheless, this is at present based on poor‐quality trial evidence. Hence, we aimed to design a systematic review and meta‐analysis for their effectiveness in alleviating premenstrual symptoms. The published randomized controlled tri‐ als (RCTs) were extracted from Google scholar, PubMed, Scopus and PROSPERO databases. The risk of bias in randomized trials was assessed by Cochrane risk‐of‐bias tool. The main outcome pa‐ rameters were analysed separately based on the Premenstrual Symptom Screening Tool and PMTS and DRSP scores. Secondary parameters of somatic, psychological, and behavioural subscale symp‐ toms of PSST were also analysed. Data synthesis was performed assuming a random‐effects model, and standardized mean difference (SMDs) was analysed using SPSS version 28.0.0 (IBM, Armonk, NY, USA). A total of 754 articles were screened, and 15 RCTs were included (n = 1211 patients). Primary results for participants randomized to an intervention reported reduced PSST (n = 9), PMTS (n = 2), and DSR (n = 4) scores with (SMD = −1.44; 95% CI: −1.72 to −1.17), (SMD = −1.69; 95% CI: −3.80 to 0.42) and (SMD = 2.86; 95% CI: 1.02 to 4.69) verses comparator with substantial heterogeneity. Physical (SMD = −1.61; 95% CI = −2.56 to −0.66), behavioural (SMD = −0.60; 95% CI = −1.55 to0.35) and mood (SMD = 0.57; 95% CI = −0.96 to 2.11) subscale symptom groupings of PSST displayed similar findings. Fifty‐three studies (n = 8) were considered at low risk of bias with high quality. Mild adverse events were reported by four RCTs. Based on the existing evidence, herbal medicine and nutritional supplements may be effective and safe for PMS.

Premenstrual syndrome (PMS) significantly lowers the quality of life and impairs personal and social relationships in reproductive-age women. Some recommendations are that inappropriate oxidative stress and inflammatory response are involved in PMS. Various nutritional supplements and herbs showed neuro-psycho-pharmacological activity with antioxidant and anti-inflammatory properties. This study aims to determine the systematic review of randomized controlled trials (RCTs) of herbal medicine and nutritional supplements in PMS. We also comprehensively highlighted the role of oxidative stress, inflammation, and mitochondrial changes on PMS with the application of computational intelligence. We used PRISMA and research question-based techniques to collect the data for evaluation of our study on different databases such as Scopus, PubMed, and PROSPERO from 1990 to 2022. The methodological quality of the published study was assessed by the modified Jadad scale. In addition, we used network visualization and word cloud techniques to find the closest terms of the study based on previous publications. While we also used computational intelligence techniques to give the idea for the classification of experimental data from PMS. We found 25 randomized controlled studies with 1949 participants ( mean ± SD : 77.96 ± 22.753 ) using the PRISMA technique, and all were high-quality studies. We also extracted the closest terms related to our study using network visualization techniques. This work has revealed the future direction and research gap on the role of oxidative stress and inflammation in PMS. In vitro and in vivo studies showed that bioactive molecules such as curcumin, allicin, anethole, thymoquinone, cyanidin 3-glucoside, gamma-linoleic acid, and various molecules not only have antioxidant and anti-inflammatory properties but also other various activities such as GABA-A receptor agonist, serotonergic, antidepressant, sedative, and analgesic. Traditional Unani Herbal medicine and nutritional supplements can effectively relieve PMS symptoms as they possess many bioactive molecules that are pharmacologically proven for the aforementioned properties. Hence, these biomolecules might influence a complex physical and psychological disease process like PMS. However, more rigorous research studies are recommended for in-depth knowledge of the efficacy of bioactive molecules on premenstrual syndrome in clinical trials.

Pimpinella anisum (Apiaceae), is indigenous to Near East and widely cultivated in the temperate regions. The fruits of Pimpinella anisum were used traditionally as a spice for flavouring bread and bakery products, and the essential oil was added to foodstuff and liqueurs as a sensory and flavoring agent. It was listed as a natural source of feed flavouring by the Council of Europe. Medicinally, the fruits were used as expectorant, digestive, antispasmodic, carminative, parasiticide, for bronchial catarrh, pertussis, spasmodic cough, spasmodic gastrointestinal complaints, to increase milk secretion, to promote menstruation, to facilitate birth, to alleviate symptoms of the male climacteric, to increase libido and externally for pediculosis and scabies. The recent studies showed that Pimpinella anisum possessed Antioxidant, hepatoprotective, nephroprotective, antihypertensive, hypolipidemic, Antiinflammatory, antimicrobial, antiparasitic, antidiabetic, local anesthetic, anticonvulsant, hypnotic, antidepressant, anxiolytic, anti-cholinesterase, neuroprotective, immunomodulatory, anticancer, laxative effects and increased milk production, prevented osteoporosis and minimized premenstrual syndrome. The current review was designed to highlight the chemical constituents and pharmacological effects of Pimpinella anisum.

Evolved over eons to encode biological assays, plants-derived natural products are still the first dawn of drugs. Most researchers have focused on natural compounds derived from commonly used Pimpinella species, such as P. anisum, P. thellungiana, P. saxifrage, and P. brachycarpa, to investigate their antioxidant, antibacterial, and anti-inflammatory properties. Ethnopharmaco-logical studies demonstrated that the genus Pimpinella has the homology characteristics of medicine and food and mainly in the therapy of gastrointestinal dysfunction, respiratory diseases, de-worming, and diuresis. The natural product investigation of Pimpinella spp. revealed numerous natural products containing phenylpropanoids, terpenoids, flavonoids, coumarins, sterols, and organic acids. These natural products have the potential to provide future drugs against crucial diseases, such as cancer, hypertension, microbial and insectile infections, and severe inflammations. It is an upcoming field of research to probe a novel and pharmaceutically clinical value on compounds from the genus Pimpinella. In this review, we attempt to summarize the present knowledge on the traditional applications, phytochemistry, and pharmacology of more than twenty-five species of the genus Pimpinella.

Premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS) refer to physical, cognitive, or affective symptoms that arise in the late luteal phase and remit with menses. The present work is a clinically focused scoping review of the last twenty years of research on treatment for these disorders. A search of key terms using the PubMed/Medline, the Cochrane Library, Embase, and Web of Science databases was performed, and 194 studies of adult women met initial inclusion criteria for review. Research studies concerning medications, pharmacological and non-pharmacological complementary and alternative medicine treatments, and surgical interventions with the most available evidence were appraised and summarized. The most high-quality evidence can be found for the use of selective serotonin reuptake inhibitors (SSRIs) and combined oral contraceptives (COCs), with gonadotropin releasing hormone (GnRH) agonists and surgical interventions showing efficacy for refractory cases. While there is some evidence of the efficacy of alternative and complementary medicine treatments such as nutraceuticals, acupuncture, and yoga, variability in quality and methods of studies must be taken into account.
... In another study, an alcohol extract (330 mg/d) was given orally to college-aged women (n = 35) for 7 days before and 3 days after each of 2 menstrual cycles. 30 Compared with placebo, aniseed treatment significantly decreased the symptoms and intensity of premenopausal syndrome. As noted in a recent review of aniseed's effects on female disorders, 8 most clinical trials evaluated aniseed in combination with different plant materials. ...

Anise (Pimpinella anisum L., family Apiaceae) is an aromatic annual herb native to the eastern Mediterranean region and western Asia. Although the small fruit is incorrectly referred to as a seed, nonetheless, the fruit is commonly known as aniseed. When ripe and dried, it is the popular spice. Aniseed and its essential oil are used in traditional therapies, for example, for relief of coughs, respiratory congestion, migraines, gastrointestinal distress, and colic; for treatment of skin infections; as a tranquilizer and aphrodisiac; and to improve lactation. Limited and preliminary clinical research has examined the efficacy of aniseed toward diabetes, dysmenorrhea, and menopausal hot flashes. Antioxidant, anti-inflammatory, and antimicrobial properties also were identified. The present narrative review summarizes human and animal studies reporting potential health benefits of aniseed and highlights areas for future research.
... Studies examining the presence of oxidative stress levels in women with PMS are scarce and ultimately reach conflicting conclusions [9,16,17]. However, recent research reports some evidence of efficacy in supplementation with other vitamins (such as magnesium [18] and vitamin B6 [19]) or herbals [20][21][22][23][24] as they may alter the hormonal, anti-inflammatory, or oxidative stress profile of women experiencing PMS and improve their symptoms. Women affected by PMS symptoms have been shown to be more likely to seek out many of the above forms of complementary and alternative medicine, including herbals, vitamins, and supplements to help cope with symptoms, [25] and even prefer these over traditional medical or surgical interventions [22]. ...

Background It has been suggested that premenstrual syndrome (PMS) may derive from either elevated oxidative stress or reduced antioxidant vitamin levels in the body; however, these relationships have been minimally studied in a large cohort of healthy women. Our objective was to estimate the association between serum concentrations of antioxidant vitamins (A, C, and E) and markers of oxidative stress (F2-isoprostane) with symptoms and severity of PMS. Methods The BioCycle study was a prospective cohort study following 259 healthy premenopausal women aged 18–44 years for up to 2 menstrual cycles. Frequency/severity of 20 PMS symptoms were assessed via questionnaires 4 times/cycle, and antioxidant vitamins and oxidative stress biomarkers were measured up to 8 times/cycle to correspond with specific cycle phases. Generalized linear models were used to estimate associations between mean antioxidant concentrations and oxidative stress biomarkers with PMS symptoms and severity; linear mixed models were used to evaluate associations with symptom severity scores within groups (e.g. depression, cravings, pain). Results Higher concentrations of serum antioxidant vitamins were largely not associated with prevalence or severity of PMS symptoms. Though a few associations were observed, only associations between mean γ-tocopherol and decreased odds of swelling of the hands/feet survived adjustment for multiple comparisons (OR 0.33, 95% CI 0.16, 0.65, per ug/dL). However, F2-isoprostanes were associated with prevalence and severity of several symptoms specifically related to depression and cravings (depression score β = 0.07, 95% CI 0.02, 0.12, per 10 ug/dL; cravings score β = 0.16, 95% CI 0.10, 0.22, per 10 ug/dL), as well as with classification of PMS severity (OR 1.07, 95% CI 1.01, 1.14, per 10 pg/dL), with these associations surviving adjustment for false discovery rate. Conclusions F2-isoprostanes, but not antioxidant vitamins, were associated with select PMS symptoms, as well as symptom and severity categories. Specific symptom relationships merit further research.

Premenstrual syndrome (PMS) is a common disorder affecting women of reproductive age, with an estimated global prevalence of 47.8%, with severe symptoms occurring in 3-8%, significantly affecting daily functioning. GABA conductance and changes in neurosteroid levels, particularly allopregnanolone, are suspected to play a substantial role in the disorder’s etiology. In this paper, we provide an overview of recent reports on the etiology and recognized therapeutic approaches, encompassing both pharmacological and non-pharmacological interventions. Our examination includes studies on SSRIs, hormonal agents, neurosteroids, supplementation, and therapeutic roles. We aim to determine the most favorable treatment regimen by comparing medication effects and alternative methods. The treatment of PMS is crucial for enhancing the quality of life for affected women. Medications used in PMS treatment should be individually selected to achieve the best therapeutic effect, considering the clinical situation of the patients.

Depression is a multifactorial disease with unknown etiology affecting globally. It’s the second most significant reason for infirmity in 2020, affecting about 50 million people worldwide, with 80% living in developing nations. Recently, a surge in depression research has been witnessed, resulting in a multitude of emerging techniques developed for prediction, evaluation, detection, classification, localization, and treatment. The main purpose of this study is to determine the volume of depression research conducted on different aspects such as genetics, proteins, hormones, oxidative stress, inflammation, mitochondrial dysfunction, and associations with other mental disorders like anxiety and stress using traditional and medical intelligence (medical with AI). In addition, it also designs a comprehensive survey on detection, treatment planning, and genetic predisposition, along with future recommendations. This work is designed through different methods, including a systematic mapping process, literature review, and network visualization. In addition, we also used VOSviewer software and some authentic databases such as Google Scholar, Scopus, PubMed, and Web of Science for data collection, analysis, and designing comprehensive picture of the study. We analyzed 60 articles related to medical intelligence, including 47 from machine learning with 513,767 subjects (mean ± SD = 10,931.212 ± 35,624.372) and 13 from deep learning with 37,917 subjects (mean ± SD = 3159.75 ± 6285.57). Additionally, we also found that stressors impact the brain's cognitive and autonomic functioning, resulting in increased production of catecholamine, decreased cholinergic and glucocorticoid activity, with increased cortisol. These factors lead to chronic inflammation and hinder the brain's normal functioning, leading to depression, anxiety, and cardiovascular disorders. In the brain, reactive oxygen species (ROS) production is increased by IL-6 stimulation and mitochondrial cytochrome c oxidase is inhibited by nitric oxide, a potent inhibitor. Proteins, lipids, oxidative phosphorylation enzymes, and mtDNA are further disposed to oxidative impairment in the mitochondria. Consequently, mitochondrial dysfunction exacerbates oxidative stress, impairs mitochondrial DNA (mtDNA) or deletions of mtDNA, increases intracellular Ca2+ levels, changes in fission/fusion and mitochondrial morphology, and lastly leads to neuronal death. This study highlights the multidisciplinary approaches to depression with different aspects using traditional and medical intelligence. It will open a new way for depression research through new emerging technologies.

Background: Plant-based remedies have been used since antiquity to treat menstrual-related diseases (MD). From the late nineteenth to the early to mid-twentieth century, Italian folk remedies to treat “women’s diseases” were documented in a vast corpus of literature sources. Aim: The purpose of this paper is to bring to light the plant-based treatments utilized by Italian folk medicine to heal clinical manifestations of premenstrual syndrome (PMS), dysmenorrhea, amenorrhea and menstrual disorders in an attempt to discuss these remedies from a modern pharmacological point of view. Moreover, we compare the medical applications described by Hippocrates with those utilized by Italian folk medicine to check if they result from a sort of continuity of use by over two thousand years. Results: Out of the 54 plants employed in Italian folk medicine, 25 (46.3%) were already documented in the pharmacopoeia of the Corpus Hippocraticum for treating MD. Subsequently, a detailed search of scientific data banks such as Medline and Scopus was undertaken to uncover recent results concerning bioactivities of the plant extracts to treat MD. About 26% of the plants used by Italian folk medicine, nowadays, have undergone human trials to assess their actual efficacy. At the same time, about 41% of these herbal remedies come back to in different countries. Conclusions: Active principles extracted from plants used by Italian folk healers could be a promising source of knowledge and represent strength candidates for future drug discovery for the management of MD.

Background and Purpose: The premenstrual syndrome is the emergence of a set of symptoms before menstrual which results in imbalance in individual's life and daily activities. Today the prescription of herbals is recommended for the treatment of the illnesses. The present study aimto pinpoint the effect of primrose oil on the premenstrual syndrome. Methods: The study was a triple blind clinical-trial which was conducted with 80 female university students residing in Lorestan Medical University hostels. The samples were selected based on the DSMIV-TR criterion for the premenstrual syndrome. Using block-randomization method, they were categorized into two groups (each 40), one treated with primrose oil and the other with placebo. The dose of the primrose oil is 1500 mg per day for the first group. The total score for sever symptom (for each from 0 to 10) was assigned at first monthly and then for three months. For the data analysis χ2 and repeated measures were deployed. Results: The score for symptom severity before the intervention for the primrose group was 53.20 ± 14.31 at the beginning. At the end of the third month, it got 33.62 ± 16.94 therewas a significant difference in the reduction of symptom severity in the follow-up periods (p < 0001). In the Placebo group, the score for sever it ysymptom before the intervention was 53.38 ± 13.93. At the end of the third month after treatment, it was 50.27 ± 16.94. This didn't show any significant difference in the decrease of the symptom severity in the follow-up period. There was a significant difference for the symptom severity in both primrose and Placebo group (p < 0.001). Conclusion: Taking the effect of primrose oil on premenstrual syndrome reduction and the harmlessness of hessrb medicals into account, bioresearches recommend primrose oil for the treatment of premenstrual syndrome.

Design A randomised control trial (RCT) was conducted to examine the efficacy of couple-based cognitive behaviour therapy (CBT) for Premenstrual Disorders (PMDs), in comparison to one-to-one CBT and a wait-list control. Methods Triangulation of quantitative and qualitative outcome measures evaluated changes pre-post intervention. Eighty three women were randomly allocated across three conditions, with 63 completing post-intervention measures, a retention rate of 76%. Results Repeated measures analysis of variance found a significant time by group interaction identifying that women in the two CBT conditions reported lower total premenstrual symptoms, emotional reactivity/mood, and premenstrual distress, in comparison to the wait list control. Significantly higher active behavioural coping post-intervention was found in the couple condition than in the one-to-one and wait list control groups. Qualitative analysis provided insight into the subjective experience of PMDs and participation in the intervention study. Across groups, women reported increased awareness and understanding of premenstrual change post-intervention. A larger proportion of women in the CBT conditions reported reduction in intensity and frequency of negative premenstrual emotional reactivity, increased communication and help-seeking, increased understanding and acceptance of embodied change, and the development of coping skills, post-intervention. Increased partner understanding and improved relationship post-intervention was reported by a greater proportion of participants in the CBT conditions, most markedly in the couple condition. Conclusion These findings suggest that one-to-one and couple CBT interventions can significantly reduce women’s premenstrual symptomatology and distress, and improve premenstrual coping. Couple based CBT interventions may have a greater positive impact upon behavioural coping and perceptions of relationship context and support. This suggests that CBT should be available for women reporting moderate-severe PMDs, with couple-based CBT offering additional benefits to a one-to-one modality.

Objective: Pimpinella anisum (P. anisum ) has different pharmacological properties such as anticonvulsant, analgesic, tranquilizer, antidepressant and anti-anxiety effects. In this study the antidepressant-like effect of aqueous and ethanolic extracts of P. anisum fruit in mice was investigated. Materials and methods: Forced swimming test (FST) and tail suspension test (TST) were used to determine the antidepressant effects of P. anisum (50, 100 and 200 mg/kg, i.p.) fruit extracts. Fluoxetine (20 mg/kg, i.p.) and imipramine (30 mg/kg, i.p.) were used as standard drugs. Results: All the three doses of aqueous and ethanolic extracts (except 50 mg/kg of aqueous extract in FST) significantly and dose-dependently reduced the immobility times in both FST and TST. All doses of extracts increased the swimming time dose-dependently, without any significant change in climbing time. In addition, all doses of ethanolic extract reduced immobility times and increased swimming time insignificantly higher than aqueous extract. But, the two extracts decreased the duration of climbing time similarly. Fluoxetine and imipramine decreased immobility time in both tests. Fluoxetine increased the swimming time without modifying climbing time. In contrast, imipramine increased climbing time without any significant change in swimming time. Conclusion: The results of this study suggest that P. anisum possesses an antidepressant-like activity similar to that of fluoxetine, which has a potential clinical value for application in the management of depression.

In the present study, we identified the effects of inhaled Pimpinella peregrina essential oil (1 and 3 %, for 21 continuous days) on scopolamine-induced memory impairment, anxiety, and depression in laboratory rats. Y-maze and radial arm-maze tests were used for assessing memory processes. Also, the anxiety and depressive responses were studied by means of the elevated plus-maze and forced swimming tests. The scopolamine alone-treated rats exhibited the following: decrease of the spontaneous alternation percentage in Y-maze test, increase of the number of working and reference memory errors in radial arm-maze test, along with decrease of the exploratory activity, the percentage of the time spent and the number of entries in the open arm within elevated plus-maze test and decrease of swimming time and increase of immobility time within forced swimming test. Inhalation of the P. peregrina essential oil significantly improved memory formation and exhibited anxiolytic- and antidepressant-like effects in scopolamine-treated rats. Our results suggest that the P. peregrina essential oil inhalation ameliorates scopolamine-induced memory impairment, anxiety, and depression. Moreover, studies on the P. peregrina essential oil may open a new therapeutic window for the prevention of neurological abnormalities closely related to Alzheimer’s disease.

We aimed to evaluate the effects of Pimpinella anisum (anise) from Apiaceae family on relieving the symptoms of postprandial distress syndrome (PDS) in this double-blind randomized clinical trial. Totally, 107 patients attending the gastroenterology clinic, aged 18-65 years, diagnosed with PDS according to ROME III criteria and signed a written consent form were enrolled. They were randomized to receive either anise or placebo, blindly, for 4 weeks. Anise group included 47 patients and received anise powders, 3 g after each meal (3 times/day). Control group involved 60 patients and received placebo powders (corn starch), 3 gafter each meal (3 times/day). The severity of Functional dyspepsia (FD) symptoms was assessed by FD severity scale. Assessments were done at baseline and by the end of weeks 2, 4 and 12. Mean scores of severity of FD symptoms and the frequency distribution of patients across the study period were compared. The age, sex, body mass index, smoking history, and coffee drinking pattern of the intervention and control groups were not significantly different. Mean (standard deviation) total scores of FD severity scale before intervention in the anise and control groups were 10.6 (4.1) and 10.96 (4.1), respectively (P = 0.6). They were 7.04 (4.1) and 12.30 (4.3) by week 2, respectively (P = 0.0001), 2.44 (4.2) and 13.05 (5.2) by week 4, respectively (P = 0.0001), and 1.08 (3.8) and 13.30 (6.2) by week 12, respectively (P = 0.0001). This study showed the effectiveness of anise in relieving the symptoms of postpartum depression. The findings were consistent across the study period at weeks 2, 4 and 12.

Premenstrual syndrome (PMS) is a common disorder. Although the etiology of PMS is not clear, to relieve from this syndrome different methods are recommended. One of them is use of medicinal herbs. This study was carried out to evaluate effects of ginger on severity of symptoms of PMS. This study was a clinical trial, double-blinded work, and participants were randomly allocated to intervention (n = 35) and control (n = 35) groups. To determine persons suffering from PMS, participants completed daily record scale questionnaire for two consecutive cycles. After identification, each participant received two ginger capsules daily from seven days before menstruation to three days after menstruation for three cycles and they recorded severity of the symptoms by daily record scale questionnaire. Data before intervention were compared with date 1, 2, and 3 months after intervention. Before intervention, there were no significant differences between the mean scores of PMS symptoms in the two groups, but after 1, 2, and 3 months of treatment, there was a significant difference between the two groups (P < 0.0001). Based on the results of this study, maybe ginger is effective in the reduction of severity of mood and physical and behavioral symptoms of PMS and we suggest ginger as treatment for PMS.

The study aimed to compare the effects of Chamomile Extract and Mefenamic acid (MA) on the intensity of Premenstrual syndrome (PMS) symptoms. This study was a clinical randomized double blind trial, carried out with 90 students living in the dorms of Iran. The participants filled the daily forms about the intensity of PMS for two consecutive months. Once the definitive diagnosis of PMS was made, the participants were divided into two groups, each receiving either Chamomile capsule 100 mg or MA 250 mg three times a day. Intensity reduction of emotional symptoms was significantly higher among Chamomile Extract-users (30.1 ± 26.6 and 33.4 ± 25.3 percent) than that among MA-users (11.6 ± 25.7 and 10.7 ± 26.8 percent) after two cycles intervention (p < 0.001). Intensity reduction of physical symptoms was not significantly different (p > 0.05) among groups. Consumption of Chamomile seems to be more effective than MA in relieving the intensity of PMS associated symptomatic psychological pains.

With respect to the high incidence of hot flash in postmenopausal women and the controversies regarding its treatment, this double-blind clinical trial was conducted to determine the effects of Pimpinella anisum on hot flashes in these women referring to rural and urban health centers of Qazvin Province in 2009. Seventy-two women with hot flashes were randomly selected according to the predetermined criteria and divided into two experimental and control groups. Their medical records at health centers were used for sampling. Each woman in the experimental group took a capsule containing 330 mg Pimpinella anisum 3 times a day while in the control group, women took 3 capsules, each containing 330 mg potato starch, over 4 weeks and after that, they were following up for 4 weeks. Before taking the capsules, they were assessed for 2 weeks about the frequency and severity of hot flashes. Data were collected through a questionnaire and an information form. Content validity method was used for validity of the tools. ANOVA and Student›s t-test were applied for statistical analysis. In the experimental group, the frequency and severity of hot flashes before the treatment were 4.21% and 56.21% and, after that, were 1.06% and 14.44% at the end of the fourth week respectively. No change was found in the frequency and severity of hot flashes in the control group. The frequency and severity of hot flashes was decreased during 4 weeks of follow up period. P. anisum is effective on the frequency and severity of hot flashes in postmenopausal women.

The objective of the current study was to translate and test psychometric properties of the Premenstrual Symptoms Screening Tool (PSST) in Iran. Using a standard "forward-backward" procedure, the English version of PSST was translated into Persian. A random sample of university students aged 18 years and over completed the questionnaire in Tehran, Iran. Psychometric properties of the Iranian version of PSST were assessed by performing reliability (internal consistency) and validity analyses [Content Validity Ratio (CVR) and Content Validity Index (CVI)]. In all, 925 female students took part in the study. Of these, 284 (30.7 %) had premenstrual syndrome (PMS) and 119 (12.9 %) had premenstrual dysphoric disorder (PMDD). Reliability of the PSST as measured by internal consistency was found to be satisfactory (Cronbach's alpha coefficient, 0.93). The content validity as assessed by CVR and CVI were desirable (0.7 and 0.8, respectively). The Iranian version of PSST seems to be a reliable and valid measure of detecting PMS and PMDD in Iranian young female populations.

Epilepsy is a brain disorder which affects about 50 million people worldwide. Ineffectiveness of the drugs in some cases and the serious side effects and chronic toxicity of the antiepileptic drugs lead to use of herbal medicine as a form of complementary and alternative medicine. In this review modern evidences for the efficacy of antiepileptic medicinal plants in Traditional Iranian Medicine (TIM) will be discussed. For this purpose electronic databases including PubMed, Scopus, Sciencedirect, and Google Scholar were searched for each of the antiepileptic plants during 1970-February 2013.Anticonvulsant effect of some of the medicinal plants mentioned in TIM like Anacyclus pyrethrum, Pimpinella anisum, Nigella sativa, and Ferula gummosa was studied with different models of seizure. Also for some of these plants like Nigella sativa or Piper longum the active constituent responsible for antiepileptic effect was isolated and studied. For some of the herbal medicine used in TIM such as Pistacia lentiscus gum (Mastaki), Bryonia alba (Fashra), Ferula persica (Sakbinaj), Ecballium elaterium (Ghesa-al Hemar), and Alpinia officinarum (Kholanjan) there is no or not enough studies to confirm their effectiveness in epilepsy. It is suggested that an evaluation of the effects of these plants on different epileptic models should be performed.

Menopause is an important stage in the life of every woman. Hot flashes are the most common climacteric symptom and a major cause of suffering in postmenopausal women. Licorice is one of the plants that is used to relieve menopausal symptoms. The present study was undertaken to evaluate the effects of licorice on hot flash symptoms in menopausal women. The participants of this randomized, double blind, clinical trial study were 60 menopausal women randomly allocated to licorice or hormone replacement therapy (HRT) groups. The participants in this trial received licorice (1140 mg/day) or HRT (a conjugated estrogen 0.312 mg/day and Medroxyprogesterone 2.5 mg/day) for 90 days. In this study we observed that licorice is not very different from hormones in terms of reducing the number and duration of hot flashes, but that HRT can reduce the severity of hot flashes significantly better than licorice can. In addition, there was no significant difference between age, education level, marital status, occupation, income, number of pregnancies, time from cessation of menstruation, and severity of hot flashes in the two groups. We observed that licorice seems more effective than HRT in improving hot flash duration, but that HRT can reduce the duration and severity of hot flashes more than licorice.

Pimpinella anisum (anise) , belonging to Umbelliferae family, is an aromatic plant which has been used In Iranian traditional medicine (especially its fruits) as carminative, aromatic, disinfectant, and galactagogue. Because the wide traditional usage of Pimpinella anisum for treatment of diseases, in this review published scientific reports about the composition and pharmacological properties of this plant were collected with electronic literature search of GoogleScholar, PubMed, Sciencedirect, Scopus, and SID from 1970 to 2011. So far, different studies were performed on aniseeds and various properties such as antimicrobial, antifungal, antiviral, antioxidant, muscle relaxant, analgesic and anticonvulsant activity as well as different effects on gastrointestinal system have been reported of aniseeds. It can also reduce morphine dependence and has beneficial effects on dysmenorrhea and menopausal hot flashes in women. In diabetic patients, aniseeds showed hypoglycemic and hypolipidemic effect and reduce lipid peroxidation. The most important compounds of aniseeds essential oil were trans-anetole, estragole, γ -hymachalen, para-anisaldehyde and methyl cavicol. Due to broad spectrum of pharmacological effects, and very few clinical studies of Pimpinella anisum , more clinical trials are recommended to evaluate the beneficial effects of this plant in human models and synthesis of new drugs from the active ingredients of this plant in future.

A phytotherapic compound containing Pimpinella anisum L., Foeniculum vulgare Miller, Sambucus nigra L., and Cassia augustifolia is largely used in Brazil for the treatment of constipation. However, the laxative efficacy of the compound has never been tested in a randomized clinical trial. The aim of this study was to evaluate the efficacy and safety of the product. This randomized, crossover, placebo-controlled, single-blinded trial included 20 patients presenting with chronic constipation according to the criteria of the American Association of Gastroenterology. The order of treatments was counterbalanced across subjects: half of the subjects received the phytotherapic compound for a 5-day period, whereas the other half received placebo for the same period. Both treatment periods were separated by a 9-day washout period followed by the reverse treatment for another 5-day period. The primary endpoint was colonic transit time (CTT), measured radiologically. Secondary endpoints included number of evacuations per day, perception of bowel function, adverse effects, and quality of life. Mean CTT assessed by X ray was 15.7 hours (95%CI 11.1-20.2) in the active treatment period and 42.3 hours (95%CI 33.5-51.1) during the placebo treatment (p < 0.001). Number of evacuations per day increased during the use of active tea; significant differences were observed as of the second day of treatment (p < 0.001). Patient perception of bowel function was improved (p < 0.01), but quality of life did not show significant differences among the study periods. Except for a small reduction in serum potassium levels during the active treatment, no significant differences were observed in terms of adverse effects throughout the study period. The findings of this randomized controlled trial allow to conclude that the phytotherapic compound assessed has laxative efficacy and is a safe alternative option for the treatment of constipation.

Premenstrual syndrome (PMS) is a common condition. Some of the most widely prescribed medications are selective serotonin reuptake inhibitors (SSRIs), based on the hypothesized role of serotonin in the production of PMS symptoms. PMS sufferers, especially those experiencing mild to moderate symptoms, are often reluctant to take this form of medication and instead buy over-the-counter preparations to treat their symptoms, for which the evidence base with regard to efficacy is limited. Hypericum perforatum (St John's wort) influences the serotonergic system. As such, this widely available herbal remedy deserves attention as a PMS treatment. To investigate the effectiveness of Hypericum perforatum on symptoms of PMS. This randomized, double-blind, placebo-controlled, crossover study was conducted between November 2005 and June 2007. Institute of Psychological Sciences, University of Leeds, Leeds, UK. PARTICIPATION: 36 women aged 18-45 years with regular menstrual cycles (25-35 days), who were prospectively diagnosed with mild PMS. Women who remained eligible after three screening cycles (n = 36) underwent a two-cycle placebo run-in phase. They were then randomly assigned to receive Hypericum perforatum tablets 900 mg/day (standardized to 0.18% hypericin; 3.38% hyperforin) or identical placebo tablets for two menstrual cycles. After a placebo-treated washout cycle, the women crossed over to receive placebo or Hypericum perforatum for two additional cycles. Symptoms were rated daily throughout the trial using the Daily Symptom Report. Secondary outcome measures were the State Anxiety Inventory, Beck Depression Inventory, Aggression Questionnaire and Barratt Impulsiveness Scale. Plasma hormone (follicle-stimulating hormone [FSH], luteinizing hormone [LH], estradiol, progesterone, prolactin and testosterone) and cytokine (interleukin [IL]-1beta, IL-6, IL-8, interferon [IFN]-gamma and tumour necrosis factor [TNF]-alpha) levels were measured in the follicular and luteal phases during Hypericum perforatum and placebo treatment. Hypericum perforatum was statistically superior to placebo in improving physical and behavioural symptoms of PMS (p < 0.05). There were no significant effects of Hypericum perforatum compared with placebo treatment for mood- and pain-related PMS symptoms (p > 0.05). Plasma hormone (FSH, LH, estradiol, progesterone, prolactin and testosterone) and cytokine (IL-1beta, IL-6, IL-8, IFNgamma and TNFalpha) levels, and weekly reports of anxiety, depression, aggression and impulsivity, also did not differ significantly during the Hypericum perforatum and placebo cycles (p > 0.05). Daily treatment with Hypericum perforatum was more effective than placebo treatment for the most common physical and behavioural symptoms associated with PMS. As proinflammatory cytokine levels did not differ significantly between Hypericum perforatum and placebo treatment, these beneficial effects are unlikely to be produced through this mechanism of action alone. Further work is needed to determine whether pain- and mood-related PMS symptoms benefit from longer treatment duration. Trial registration number (International Standard Randomised Controlled Trial Number Register) ISRCTN31487459.

As many women experiencing symptoms of premenstrual syndrome (PMS) seek relief from natural products (NP), health care providers should have quality information available to aid women in making evidence-based decisions regarding use of these products. To identify herbs, vitamins and minerals advocated for the treatment of PMS and/or PMDD and to systematically review evidence from randomized controlled trials (RCTs) to determine their efficacy in reducing severity of PMS/PMDD symptoms. Searches were conducted from inception to April 2008 in Clinical Evidence, The Cochrane Library, Embase, IBID, IPA, Mayoclinic, Medscape, MEDLINE Plus, Natural Medicines Comprehensive Database and the Internet to identify RCTs of herbs, vitamins or minerals advocated for PMS. Bibliographies of articles were also examined. Included studies were published in English or French. Studies were excluded if patient satisfaction was the sole outcome measure or if the comparator was not placebo or recognized therapy. Sixty-two herbs, vitamins and minerals were identified for which claims of benefit for PMS were made, with RCT evidence found for only 10. Heterogeneity of length of trials, specific products and doses, and outcome measures precluded meta-analysis for any NP. Data supports the use of calcium for PMS, and suggests that chasteberry and vitamin B6 may be effective. Preliminary data shows some benefit with ginkgo, magnesium pyrrolidone, saffron, St. John's Wort, soy and vitamin E. No evidence of benefit with evening primrose oil or magnesium oxide was found. Only calcium had good quality evidence to support its use in PMS. Further research is needed, using RCTs of adequate length, sufficient sample size, well-characterized products and measuring the effect on severity of individual PMS symptoms.

To explore the experience of reproductive-age women in the French population with premenstrual syndrome (PMS) by estimating perceived symptom prevalence, identifying risk factors, and quantifying the burden of symptoms. This study also assesses the stability of the PMS diagnosis over a 1-year period of follow-up. The prevalence of reported PMS was estimated from a population-based cohort of 2863 French women interviewed in 2003 and 2004. Multivariate logistic regressions were used to identify risk factors associated with PMS. PMS fluctuation was studied by comparing women's responses in 2003 and 2004. Results show that 4.1% of women qualified for severe PMS (six symptoms) and 8.1% qualified for moderate PMS (one to five symptoms), resulting in 12.2% of women who reported PMS symptoms that impacted their daily lives. Risk factors for PMS fell into three categories: hormonal, psychosocial, and physiological, with life stressors and exogenous hormonal exposure exerting the most substantial impact. Results also indicate a high level of intraindividual variation in PMS status over time; among women who qualified for PMS during 1 or both years of the study, 72% demonstrated fluctuation in their PMS status. More women report suffering from distressing premenstrual symptoms than are captured by strict premenstrual dysphoric disorder (PMDD) diagnostic criteria. The impact of PMS symptoms on women appears to fluctuate over time, however, producing greater variability in the syndrome than previously recognized. Clinicians should be mindful of high intraindividual variability in the syndrome when advising patients about long-term management.

Premenstrual disorders negatively affect millions of U.S. women. The premenstrual disorder at the most severe end of the spectrum is premenstrual dysphoric disorder (PMDD). The specific diagnostic criteria developed for PMDD and the availability of validated symptom diaries have allowed a more organized study of severe premenstrual disorders. The U.S Food and Drug Administration has now approved 4 agents for the treatment of PMDD: 3 antidepressants (i.e., selective serotonin reuptake inhibitors) and 1 low-dose combination oral contraceptive (COC) that contains the progestin drospirenone and is administered using a regimen of 24 days of active pills in a 28-day cycle (drospirenone/20EE-24/4). Drospirenone is unique among progestins used in COCs in that it has both antimineralocorticoid and antiandrogenic activities. Two pivotal studies have shown drospirenone/20EE-24/4 to be effective in treating the mood, physical and behavioral symptoms of PMDD and symptoms specifically associated with food, water retention and negative interpersonal relationships.

Up to 80 % of the Western female population experience premenstrual syndrome (PMS). Long-term pharmacological therapy is unacceptable to most women, and is not warranted for moderate symptoms. Nutritional therapies are popular, but lack a clear evidence base. Anecdotal evidence suggests beneficial effects of soy isoflavones because of their influence on endogenous oestrogen and actions on specific tissues. The effect of isolated soya protein (ISP) containing 68 mg/d (aglycone equivalents) soy isoflavones (IF) on premenstrual symptom severity was studied in a seven-menstrual cycle, double-blind, placebo-controlled, crossover intervention study in twenty-three women with prospectively confirmed PMS aged 18-35 years and BMI 19-30 kg/m(2). ISP containing IF or milk protein placebo was consumed for two complete menstrual cycles. ISP containing IF (genistein, daidzein, equol) were measured in 24 h urine samples. After two cycles of ISP containing IF intervention, total symptoms (F(2,36) 8.20, P=0.000) and physical symptoms (F(2,36) 8.18, P=0.000) were significantly reduced compared with baseline after both active and placebo treatments, although differences between active and placebo treatment were non-significant. Specific premenstrual symptoms, headache (F(2,32) 4.10, P=0.026) and breast tenderness (F(2,32) 4.59, P=0.018), were reduced from baseline after soy IF, but not milk protein placebo. Cramps (F(2,32) 4.15, P=0.025) and swelling (F(2,32) 4.64, P=0.017) were significantly lower after active treatment compared with placebo. Concentrations of genistein and daidzein were increased following soy IF consumption, but equol production did not enhance symptom reduction. The present study showed that ISP containing IF may have potential to reduce specific premenstrual symptoms via non-classical actions.

Tens of millions of Americans use herbal products and/or dietary supplements, yet scant data are available regarding the purity, safety, or efficacy of these substances. A better understanding of usage trends and patient attitudes toward self-initiated supplementation is vital to obtaining accurate and complete medical history data. To survey Americans aged approximately 60 years and older regarding their use of herbal products and dietary supplements and their attitudes and knowledge regarding the safety of these popular substances. A face-to-face, 35-item survey was administered to 267 men and women residing in the Kansas City, Mo-metropolitan area. Researchers documented usage patterns for, attitudes about, and knowledge of herbal products and dietary supplements in this population. Fifty-six (21%) respondents were currently taking at least one herbal product or dietary supplement, and potential for adverse drug reactions was apparent in 12 (19%). Glucosamine, garlic, Echinacea, and Gingko biloba were the most frequently cited substances used by survey participants. White women with at least some college education were most likely to report taking these products. However, preservation of health was by far the most predictive indicator for use of herbal products and dietary supplements. Subjects were found to be receptive to patient education efforts for these products. Although substantial misconceptions about herbal products and dietary supplements exist among older Americans, most individuals in this population are interested in receiving additional information about these products. Excellent opportunities exist for expanded patient education--and improved patient care.

To substantiate the claims of Unani and Arabian traditional medicine practitioners on the gastroprotective potential effect of a popular spice anise, "Pimpinella anisum L." on experimentally-induced gastric ulceration and secretion in rats. Acute gastric ulceration in rats was produced by various noxious chemicals including 80% ethanol, 0.2 mol/L NaOH, 25% NaCl and indomethacin. Anti-secretory studies were undertaken using pylorus-ligated Shay rat technique. Levels of gastric non-protein sulfhydryls (NP-SH) and wall mucus were estimated and gastric tissue was also examined histologically. Anise aqueous suspension was used in two doses (250 and 500 mg/kg body weight) in all experiments. Anise significantly inhibited gastric mucosal damage induced by necrotizing agents and indomethacin. The anti-ulcer effect was further confirmed histologically. In pylorus-ligated Shay rats, anise suspension significantly reduced the basal gastric acid secretion, acidity and completely inhibited the rumenal ulceration. On the other hand, the suspension significantly replenished ethanol-induced depleted levels of gastric mucosal NP-SH and gastric wall mucus concentration. Anise aqueous suspension possesses significant cytoprotective and anti-ulcer activities against experimentally-induced gastric lesions. The anti-ulcer effect of anise is possibly prostaglandin-mediated and/or through its anti-secretory and antioxidative properties.

Ethnopharmacological relevance: Anise is a well-recognized plant in Traditional Persian Medicine (TPM) sources. Anise oil has been suggested for the treatment of bowel disorders in Persian medical textbooks. Based on TPM scholars, this ingredient has a favorable effect on gastrointestinal diseases. We did this trial to determine the efficacy and safety of enteric coated capsules of anise oil for clinical symptoms of irritable bowel syndrome (IBS). Methods and materials: This three-armed double-blind clinical trial was carried out from August 2014 to February 2015. 120 patients were divided into three groups by block randomization: AnisEncap, placebo and Colpermin(®). Patients in each group received 3 similar capsules per day for 4 weeks. The primary outcome was measured as a visual analogue scale (VAS) score, and the secondary outcome was assessed with an IBS-quality of life questionnaire. Chi-squared tests were used for categorical variables and t-tests to compare continuous variables. Results: There were no significant differences in demographic characteristics among the three groups. According to intention-to-treat sample analysis, 75% of patients in the treatment group, 35% in the placebo group and 52.5% in active control group were free from IBS symptoms (P<0.001). The effectiveness of AnisEncap in improving IBS symptoms (abdominal discomfort or pain, bloating, diarrhea, constipation severity, difficulty in defecation, gastroesophageal reflux, headache, tiredness, overall satisfaction and quality of life) was significantly greater than placebo or Colpermin(®) after the 4-week treatment period and the 2-week follow-up period (P<0.0001). The number needed to treat for enteric coated capsules of anise oil was 4, which indicated significantly superior efficacy compared to the other two groups (P<0.001). Conclusion: The effectiveness of AnisEncap was superior to that of placebo or Colpermin(®) in patients with IBS. Further studies are suggested to find the main mechanism of action of anise oil in this regard.

Study design: This randomized, double-blind, placebo-controlled, crossover study was conducted between November 2005 and June 2007. Setting: Institute of Psychological Sciences, University of Leeds, Leeds, UK. Participants: 36 women aged 18-45 years with regular menstrual cycles (25-35 days), who were prospectively diagnosed with mild PMS. Intervention: Women who remained eligible after three screening cycles (n = 36) underwent a two-cycle placebo run-in phase.

Main outcome measures: Symptoms were rated daily throughout the trial using the Daily Symptom Report. Secondary outcome measures were the State Anxiety Inventory, Beck Depression Inventory, Aggression Questionnaire and Barratt Impulsiveness Scale. Plasma hormone (follicle-stimulating hormone [FSH], luteinizing hormone [LH], estradiol, progesterone, prolactin and testosterone) and cytokine (interleukin [[IL]-1 beta, IL-6, IL-8, interferon [IFN]-gamma and tumour necrosis factor [TNF]-alpha) levels were measured in the follicular and luteal phases during Hypericum perforatum and placebo treatment. Results: Hypericum perforatum was statistically superior to placebo in improving physical and behavioural symptoms of PMS (p < 0.05). There were no significant effects of Hypericum perforatum compared with placebo treatment for mood- and pain-related PMS symptoms (p>0.05). Plasma hormone (FSH, LH, estradiol, progesterone, prolactin and testosterone) and cytokine (IL-1 beta, IL-6, IL-8, IFN gamma and TNF alpha) levels, and weekly reports of anxiety, depression, aggression and impulsivity, also did not differ significantly during the Hypericum perforatum and placebo cycles (p > 0.05). Conclusion: Daily treatment with Hypericum perforatum was more effective than placebo treatment for the most common physical and behavioural symptoms associated with PMS. As proinflammatory cytokine levels did not differ significantly between Hypericum perforatum and placebo treatment, these beneficial effects are unlikely to be produced through this mechanism of action alone. Further work is needed to determine whether pain- and mood-related PMS symptoms benefit from longer treatment duration.

Isoflavonoids are a class of secondary metabolites, which comprise amongst others the subclasses of isoflavones, isoflavans, pterocarpans and coumestans. Isoflavonoids are abundant in Leguminosae, and many of them can bind to the human estrogen receptor (hER) with affinities similar to or lower than that of estradiol. Dietary intake of these so-called phytoestrogens has been associated with positive effects on menopausal complaints, hormone-related cancers, and osteoporosis. Therefore, phytoestrogens are used as nutraceuticals in functional foods or food supplements. Most of the isoflavonoids show agonistic activity towards both hERα and hERβ, the extent of which is modulated by the substitution pattern of their skeleton (i.e.-OH, -OCH(3)). Interestingly, substitutions consisting of a five-carbon prenyl group often seem to result in an antiestrogenic activity. There is growing evidence that the action of some of these prenylated isoflavonoids is tissue-specific, suggesting that they act like selective estrogen receptor modulators (SERMs), such as the well-known chemically synthesized raloxifene and tamoxifen. These so-called phytoSERMS might have high potential for realizing new food and pharma applications. In this review, the structural features of isoflavonoids (i.e. the kind of skeleton and prenylation (e.g. chain or pyran), position of the prenyl group on the skeleton, and the extent of prenylation (single, double)) are discussed in relation to their estrogenic activity. Anti-estrogenic and SERM activity of isoflavonoids was always associated with prenylation, but these activities did not seem to be confined to one particular kind/position of prenylation or isoflavonoid subclass. Few estrogens with agonistic activity were prenylated, but these were not tested for antagonistic activity; possibly, these molecules will turn out to be phytoSERMs as well. Furthermore, the data on the dietary occurrence, bioavailability and metabolism of prenylated isoflavonoids are discussed.

The composition of the essential oil ofPimpinella anisum L fruit is determined by GC and GC-MS. The volatile oil content obtained by hydrodistillation was 1.91%. Ten compounds representing 98.3% of the oil was identified. The main constituents of he oil obtained from dried fruits were trans-a nethole (93.9%) and estragole (2.4%). The olfactorially valuable constituents that were found with concentration higher than 0.06% were (E)-methyeugenol, α-cuparene, α-himachalene, β-bisabolene, p-anisaldehyde and cis-anethole. Also, the different concentrations of anise oil exerted varying levels of inhibitory effects on the mycelial growth off/ternaria alternata, Aspergillus niger andAspergillus parasiticus used in experimental. The results showed that the most effected fungus from anise oil wasA. parasiticus, which is followed byA. niger andA. alternata. Individual of this plant oil may provide a useful to achive adequate shelf-life of foods.

In this study, antioxidant and antimicrobial activities of water and ethanol extracts of anise (Pimpinella anisum L.) seed (PAS) were investigated. The antioxidant properties of both extracts of PAS were evaluated using different antioxidant tests, including reducing power, free radical scavenging, superoxide anion radical scavenging, hydrogen peroxide scavenging, and metal chelating activities. Twenty μg/ml of water and ethanol extracts exhibited 99.1 and 77.5% inhibition of peroxidation in linoleic acid system, which was greater than the same concentration of α-tocopherol (36.1%). These various antioxidant activities were compared with synthetic antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and α-tocopherol. The water extract of PAS exhibited greater antioxidant capacity than that of ethanol. Antimicrobial activity tests were carried out using disc diffusion methods with 10 microbial species.

Three antiviral and immunostimulating substances (LC1, LC2 and LC3) were isolated from a hot water extract of seeds of Pimpinella anisum by combination of anion-exchange, gel filtration and hydrophobic interaction column chromatographies. Chemical and spectroscopic analyses revealed them to be lignin-carbohydrate-protein complexes. These lignin-carbohydrate complexes (LCs) showed antiviral activities against herpes simplex virus types 1 and 2 (HSV-1 and -2), human cytomegalovirus (HCMV) and measles virus. LCs were also found to interfere with virus adsorption to the host cell surface and directly inactivate viruses. Furthermore, they enhanced nitric oxide (NO) production by inducing iNOS mRNA and protein expression in RAW 264.7 murine macrophage cells. The induced mRNA expression of cytokines including IL-1β and IL-10 was also apparent. These results suggest that the lignin-carbohydrate-protein complexes from P. anisum possessed potency as functional food ingredients against infectious diseases.

To investigate the biological activities of Justicia pectoralis Jacq. (Acanthaceae), an herbal medicine used in Costa Rica (CR) for the management of menopausal symptoms and dysmenorrhea. The aerial parts of J. pectoralis were collected, dried and extracted in methanol. To establish possible mechanisms of action of JP for the treatment of menopausal symptoms, the estrogenic and progesterone agonists, and antiinflammatory activities were investigated. The methanol extract (JP-M) was tested in ER and PR binding assays, a COX-2 enzyme inhibition assay, the ERbeta-CALUX assay in U2-OS cells, as well as reporter and endogenous gene assays in MCF-7 K1 cells. The JP-M extract inhibited COX-2 catalytic activity (IC(50) 4.8 microg/mL); bound to both ERalpha and ERbeta (IC(50) 50 microg/mL and 23.1 microg/mL, respectively); induced estrogen-dependent transcription in the ERbeta-CALUX; and bound to the progesterone receptor (IC(50) 22.8 microg/mL). The extract also modulated the expression of endogenous estrogen responsive genes pS2, PR, and PTGES in MCF-7 cells at a concentration of 20 microg/mL. Activation of a 2 ERE-construct in transiently transfected MCF-7 cells by the extract was inhibited by the estrogen receptor antagonist ICI 182,780, indicating that the effects were mediated through the estrogen receptor. Finally, the extract weakly enhanced the proliferation of MCF-7 cells, however this was not statistically significant as compared with DMSO controls. Extracts of J. pectoralis have estrogenic, progestagenic and anti-inflammatory effects, and thus have a plausible mechanism of action, explaining its traditional use for menopause and PMS.

During the reproductive years, most of menstruating women experience symptoms of premenstrual syndrome (PMS), which is incapacitating in up to 10% of cases. According to complicated etiology, various therapeutic approaches have been proposed. Because PMS is a chronic situation, special attention should be paid to the side-effects of pharmacological interventions. Herbal medicine is a recent favorable therapeutic approach owing to fewer side-effects. We aimed to determine the effect of Ginkgo biloba L. on the symptoms of PMS. This was a single-blind, randomized, placebo-controlled trial conducted from November 2007 to April 2008. The students with PMS, living in dormitories of a medical university (Tehran), who met the inclusion criteria entered the study. The students filled out the daily symptom rating forms in two consecutive menstrual cycles. After we verified the PMS diagnosis in 90 students, the participants were randomly assigned to experiment and placebo groups and took G. biloba L. tablets (containing 40 mg leaf extracts) or placebo three times a day from the 16th day of the menstrual cycle to the 5th day of the next cycle. Data were collected using daily symptom rating forms. Eighty-five (85, 94.4%) participants completed the study. The two groups were similar in terms of demographic characteristics and baseline overall severity of symptoms. After the intervention, there was a significant decrease in the overall severity of symptoms and physical and psychologic symptoms in both Ginkgo (23.68%) and placebo (8.74%) groups (p < 0.001). However, the mean decrease in the severity of symptoms was significantly more in the Ginkgo group compared to the placebo group (p < 0.001). G. biloba L. can reduce the severity of PMS symptoms. Further research on active ingredients and also the efficacy and safety of various doses and treatment durations of Ginkgo are required.

Fennel, Foeniculum vulgare, and anise, Pimpinella anisum, are plants which have been used as estrogenic agents for millennia. Specifically, they have been reputed to increase milk secretion, promote menstruation, facilitate birth, alleviate the symptoms of the male climacteric, and increase libido. In the 1930s, some interest was shown in these plants in the development of synthetic estrogens. The main constituent of the essential oils of fennel and anise, anethole, has been considered to be the active estrogenic agent. However, further research suggests that the actual pharmacologically active agents are polymers of anethole, such as dianethole and photoanethole.

The efficacy of standardized Ginkgo biloba extract (EGb 761) in treating congestive symptoms of premenstrual syndrome (PMS) was evaluated in a controlled multicentric double blind study versus placebo. The population studied was a group of 165 women aged between 18 to 45, in genital activity period, suffering since 3 cycles from congestive premenstrual troubles during at least 7 days per cycle. The characteristics of patients and PMS were the same in both groups (EGb 761 and placebo). The observation of one menstrual cycle confirmed the diagnosis of PMS. Then, during the 2 following cycles, each patient received either EGb 761 or placebo from the 16th day of the first cycle till the 5th day of the next cycle. A double evaluation of the symptoms was realized by the patient using a daily rating scale (auto-evaluation), by the practitioner during visits at the premenstrual phase before and after the two cycles treatment. From 165 patients included, 143 observations were available. With a good acceptability, EGb 761 was effective against the congestive symptoms of PMS, particularly breast symptoms with a statistical significance between EGb 761 and placebo. Neuropsychological symptoms were also improved. EGb 761 is an alternative of interest to therapeutics already used in treating PMS or can be associated without any inconvenience.

A systematic literature search of clinical trials of evening primrose oil (EPO) for the treatment of the premenstrual syndrome (PMS) was carried out with a view to performing a meta-analysis. Only seven placebo-controlled trials were found but only in five trials was randomization clearly indicated. Inconsistent scoring and response criteria made statistical pooling and hence a rigorous meta-analysis inappropriate. The two most well-controlled studies failed to show any beneficial effects for EPO, although because the trials were relatively small modest effects cannot be excluded. Nonetheless, on current evidence EPO is of little value in the management of premenstrual syndrome.

This study investigates anticonvulsant effects of an essential oil of the fruits of Pimpinella anisum (Umbelliferae), a folkloric remedy in the Iranian traditional medicine, against seizures induced by pentylenetetrazole (PTZ) or maximal electroshock (MES) in male mice. The essential oil suppressed tonic convulsions induced by PTZ or MES. It also elevated the threshold of PTZ-induced clonic convulsions in mice. The essential oil produced motor impairment. However, this effect was not observed at the doses and time courses needed for anticonvulsant activity.

The problem of drug dependence still remains unresolved. In the present study the effects of an essential oil of Pimpinella anisum (Umbeliferae) on the expression and acquisition of conditioned place preference (CPP) induced by morphine in mice were investigated. Subcutaneous (s.c.) injections of morphine (2-5 mg/kg) produced place preference in a dose-dependent manner. Furthermore, intraperitoneal (i.p.) injection of the essential oil of P. anisum (0.125-0.5 ml/kg) induced conditioned place aversion (CPA). The mice which have received the essential oil of the P. anisum (0.125-0.5 ml/kg, i.p.) as well as the oil with morphine (5 mg/kg, s.c.) reduced the morphine effect. Administration of the essential oil of P. anisum (0.125-0.5 ml/kg, i.p.) on the test day did not show any effect on morphine action. It appeared that pre-administration with bicuculline (GABA(A) receptor antagonist) (1.5 mg/kg, i.p., 20 min before essential oil) diminished the effect of the essential oil of the P. anisum on morphine which induced CPP, but this result was not found for the GABA(B) receptor antagonist, CGP35348 (200 and 400 mg/kg, i.p., 10 min before essential oil). In conclusion, it appeared that the essential oil of the P. anisum may reduce the morphine effects via a GABAergic mechanism.

A review of measures of menstrual cycle symptoms is provided. This will enable researchers and clinicians to make the appropriate choice of method for their study requirements. In recent years, these measures have taken the form of retrospective questionnaires (rating severity of symptoms from memory) and prospective diaries (daily checklists of symptoms). Many of these draw on aspects of the well-known retrospective questionnaires, the Menstrual Distress Questionnaire and Premenstrual Assessment Form, in their development and validation. Each measure will be briefly described, followed by comments on its development, psychometric properties and finally an evaluation of its strengths and weaknesses. It concludes with an examination of the implications arising from the review, and some recommendations that menstrual cycle researchers and clinicians may wish to consider, as they decide upon the most appropriate measure for their needs.

Premenstrual syndrome, a common cyclic disorder of young and middle-aged women, is characterized by emotional and physical symptoms that consistently occur during the luteal phase of the menstrual cycle. Women with more severe affective symptoms are classified as having premenstrual dysphoric disorder. Although the etiology of these disorders remains uncertain, research suggests that altered regulation of neurohormones and neurotransmitters is involved. Premenstrual syndrome and premenstrual dysphoric disorder are diagnoses of exclusion; therefore, alternative explanations for symptoms must be considered before either diagnosis is made. The disorders can manifest with a wide variety of symptoms, including depression, mood lability, abdominal pain, breast tenderness, headache, and fatigue. Women with mild symptoms should be instructed about lifestyle changes, including healthy diet, sodium and caffeine restriction, exercise, and stress reduction. Supportive strategies, such as use of a symptom diary, may be helpful in diagnosing and managing the disorders. In women with moderate symptoms, treatment includes both medication and lifestyle modifications. Dietary supplements, such as calcium and evening primrose oil, may offer modest benefit. Selective serotonin reuptake inhibitors such as fluoxetine and sertraline are the most effective pharmacologic agents. Prostaglandin inhibitors and diuretics may provide some relief of symptoms. Only weak evidence supports the effectiveness of gonadotropin-releasing hormone agonists, androgenic agents, estrogen, progesterone, or other psychotropics, and side effects limit their use.

Anise (Pimpinella anisum) has been used as a traditional aromatic herb in many drinks and baked foods because of the presence of volatile oils in its fruits commonly known as seeds. Hot water extracts of the seeds have been used also in folk medicine for their diuretic and laxative effect, expectorant and anti-spasmodic action, and their ability to ease intestinal colic and flatulence. The aim of this work was to study the effect of aniseed oil on transport processes through intestinal and renal epithelia and determine its mechanism of action. The essential oils were extracted from the seeds by hydrodistillation and analyzed by gas chromatography. Aniseed oil enhanced significantly glucose absorption from the rat jejunum and increased the Na+-K+ ATPase activity in a jejunal homogenate in a dose dependent manner. The oil, however, exerted no effect on water absorption from the colon and did not alter the activity of the colonic Na+-K+ ATPase. When added to drinking water, it reduced the volume of urine produced in the rat and increased the activity of the renal Na+-K+ ATPase even at extremely low concentrations. It was concluded that aniseed oil increases glucose absorption by increasing the activity of the Na+-K+ ATPase and consequently the sodium gradient needed for the sugar transport. Its anti-diuretic effect is also mediated through a similar mechanism in the kidney whereby a stimulation of the Na+-K+ pump increases tubular sodium reabsorption and osmotic water movement. The colonic Na+-K+ ATPase was however, resistant to the oil.

This study aimed to investigate the efficacy of St. John's wort extract (SJW) as a treatment for premenstrual symptoms. The study was a randomized, double-blinded, placebo-controlled trial, with two parallel treatment groups. After a no-treatment baseline cycle, volunteers were randomized to either SJW or placebo for a further two menstrual cycles. A postal trial conducted from The University of Reading, Berkshire, England. One hundred and sixty-nine (169) normally menstruating women who experienced recurrent premenstrual symptoms were recruited onto the study. One hundred and twenty-five (125) completed the protocol and were included in the analysis. Six hundred milligrams (600) mg of SJW (standardized to contain 1800 microg of hypericin) or placebo (containing lactose and cellulose). A menstrual diary was used to assess changes in premenstrual symptoms. The anxiety-related subgroup of symptoms of this instrument was used as the primary outcome measure. After averaging the effects of treatment over both treatment cycles it was found that there was a trend for SJW to be superior to placebo. However, this finding was not statistically significant. The possibility that this nonsignificant finding resulted from insufficient statistical power in the study, rather than a lack of efficacy of SJW, is discussed. Following this discussion the recommendation is made that, in future, similar studies should be powered to detect a minimum clinically relevant difference between treatments.

A variety of instruments have been used in an attempt to operationalize DSM-IV criteria for premenstrual dysphoric disorder (PMDD) and to understand clinically significant premenstrual syndrome (PMS). The objectives of this research were to devise a simple user friendly screening tool to identify women who suffer from severe PMS/PMDD and who are likely to benefit from treatment. Five hundred and nineteen women, between the ages of 18 and 55 yrs, who were seen at a primary care facility completed "The Premenstrual Symptoms Screening tool" (PSST). The PSST reflects and 'translates' categorical DSM-IV criteria into a rating scale with degrees of severity. The results are in line with reported prevalence rates from several recent large prospective studies. We believe that the PSST applies a necessary degree of measure of severity and impact of premenstrual symptoms, establishes quickly if women qualify for PMDD, and is less time consuming and more practical than two cycles of prospective charting. This fast simple tool is an effective screening tool and an important starting point for further assessment.

The aim of this double-blind and placebo-controlled trial was to investigate whether saffron (stigma of Crocus sativus L.) could relieve symptoms of premenstrual syndrome (PMS). Double-blind, randomised and placebo-controlled trial. Departments of Gynaecology/Obstetrics and Psychiatry, Tehran and Zanjan University of Medical Sciences. Women aged 20-45 years with regular menstrual cycles and experience of PMS symptoms for at least 6 months were eligible for the study. Women were randomly assigned to receive capsule saffron 30 mg/day (15 mg twice a day; morning and evening) (group A) or capsule placebo (twice a day) for a two menstrual cycles (cycles 3 and 4). The primary outcome measure was the Daily Symptom Report, and secondary outcome measure was the Hamilton Depression Rating Scale. In this trial, saffron was found to be effective in relieving symptoms of PMS. A significant difference was observed in efficacy of saffron in cycles 3 and 4 in the Total Premenstrual Daily Symptoms and Hamilton Depression Rating Scale. The results of this study indicate the efficacy of C. sativus L. in the treatment of PMS. However, a tolerable adverse effects profile of saffron may well confirm the application of saffron as an alternative treatment for PMS. These results deserved further investigations.
