Hypericum in the treatment of seasonal affective disorders.
ABSTRACT Seasonal affective disorder (SAD) represents a subgroup of major depression with a regular occurrence of symptoms in autumn/winter and full remission in spring/summer. Light therapy (LT) has become the standard treatment of this type of depression. Apart from this, pharmacotherapy with antidepressants also seems to provide an improvement of SAD symptoms. The aim of this controlled, single-blind study was to evaluate if hypericum, a plant extract, could be beneficial in treating SAD patients and whether the combination with LT would be additionally advantageous. Patients who fulfilled DSM-III-R criteria for major depression with seasonal pattern were randomized in a 4-week treatment study with 900 mg of hypericum per day combined with either bright (3000 lux, n = 10) or dim (< 300 lux, n = 10) light condition. Light therapy was applied for 2 hours daily. We found a significant (MANOVA, P < .001) reduction of the Hamilton Depression Scale score in both groups but no significant difference between the two groups. Our data suggest that pharmacologic treatment with hypericum may be an efficient therapy in patients with seasonal affective disorder.

ABSTRACT: Herbal medicines were the "sole" source of medicine for thousands of years, in every culture since the advent of human civilization. Today, patients are increasing the use of these botanicals for numerous conditions, such as mood and cognition. This article will explore commonly used herbal remedies for mood and cognition functioning. It is imperative that nurses and nurse practitioners obtain expertise with these botanicals with regard to efficacy, adverse effects and contraindications, possible drug interactions, and safety considerations.Holistic nursing practice 01/2012; 26(1):38-51. · 0.34 Impact Factor

ABSTRACT: The popularity of natural or "alternative" remedies to treat medical and psychiatric disorders has accelerated dramatically over the past decade, in the United States and worldwide. This article reviews the evidence for clinical efficacy, active ingredients, mechanisms of action, recommended dosages, and toxicities of the 3 best-studied putative natural antidepressants, St. John's wort (hypericum), S-adenosyl methionine, and the Omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid. Despite growing evidence for efficacy and safety, more comprehensive studies are required before these remedies can be recommended as safe and effective alternatives or adjuncts to conventional psychotropic agents. There are limited data regarding safety in pregnancy and during lactation, and caution is therefore recommended in women who are pregnant or breastfeeding.Obstetrics and Gynecology Clinics of North America 12/2009; 36(4):789-807, x. · 1.45 Impact Factor

ABSTRACT: Allergic rhinitis (AR) is a disease with high prevalence. In AR, exposure to airborne allergens elicits an allergic response which involves epithelial accumulation of effector cells - e.g. mast cells and basophils - and subsequent inflammation. During the early response in AR, histamine has been found to be the most abundant mediator and it is associated with many symptoms of this disease mediated through the histamine H1 receptor. Therefore, anti-histamines have a role to play in the management of AR. However, the available anti- histamines have certain well-known side effects like sedation and potential pro-arrythmic effects owing to their interactions with other drugs, as well as having poor or no effect on platelet activating factor (PAF) which also plays an important role in AR. This article is a qualitative systematic literature review on the pharmacological profile of rupatadine in order to evaluate its safety and efficacy in AR as compared to other anti-histamines. Rupatadine is a once-daily non-sedative, selective, long-acting H1 anti-histamine with antagonistic PAF effects through its interaction with specific receptors. Rupatadine significantly improves nasal symptoms in patients with AR. It has a good safety profile and is devoid of arrythmogenic effects. These properties make rupatadine a suitable first line anti-histamine for the treatment of AR.
