KEYWORDS
Flowers, human psychology, emotional responses, mood enhancement, therapeutic applications, cultural
significance, well-being
1. INTRODUCTION
Flowers are unique in human history, symbolizing love, beauty, and
celebration(de Oliveira Paiva et al., 2020). Beyond their visual allure,
flowers are known to have a profound impact on human emotions and
psychology (Connell, 2005). This review aims to provide a comprehensive
overview of the various ways in which different flowers influence human
psychological states (Connell, 2004).
1.1 Emotional Responses to Flowers
Research has shown that exposure to flowers can elicit positive emotional
responses such as happiness, calmness, and joy (Fallahi et al., 2020; Lin et
al., 2020). Certain flowers have been associated with feelings of love and
admiration, while others evoke relaxation and tranquility(Hassan et al.,
2019). The colors, scents, and visual aesthetics of flowers play a significant
role in shaping these emotional responses(Kaplan, 1995).
1.2 Mood Enhancement and Stress Reduction
Flower arrangements and bouquets have been shown to enhance mood
and reduce stress levels. The presence of flowers in indoor environments,
such as homes and workplaces, has been linked to increased feelings of
contentment and decreased feelings of anxiety (Uwajeh et al., 2019). The
practice of flower arranging and gardening has also been identified as a
therapeutic activity that can promote emotional well-being (Ahern and
Schwartz, 1985; Neale et al., 2017).
1.3 Therapeutic Applications
The impact of flowers on human psychology has found its way into various
therapeutic applications (Detweiler et al., 2009; Murphy et al., 2010).
Horticultural therapy, for instance, incorporates gardening and flower-
related activities to alleviate symptoms of depression, anxiety, and stress
(Han et al., 2018). Additionally, flowers are being integrated into
healthcare settings to enhance patient recovery rates and reduce the need
for pain medication (Bassi et al., 2018)
1.4 Cultural and Symbolic Significance
Different cultures and societies attribute unique symbolic meanings to
various flowers (Krishnan and Novy, 2016). Understanding these cultural
associations can offer insights into the emotional and psychological
responses they elicit. Flower holds spiritual significance in many Eastern
cultures and western cultures, symbolizing purity and enlightenment
(Fallahi et al., 2020).
1.5 Future Directions and Implications
While there is a growing body of research on the impact of flowers on
human psychology, many aspects remain unexplored (Du et al., 2022; Ng
et al., 2018). Further investigation into the specific mechanisms by which
flowers influence mood and emotions, as well as the potential long-term
effects of consistent flower exposure, is warranted (Chu et al., 2021; Park
et al., 2009). Additionally, the practical implications of incorporating
flowers into different environments should be thoroughly examined to
optimize their psychological benefits (Gonzalez and Kirkevold, 2016;
Zhao et al., 2019).
Some sort of impact that a specific flower can act to human psychology are
as follow:
Roses
Roses are universally recognized symbols of love and affection. Research
suggests that the sight and scent of roses can elicit feelings of joy,
admiration, and romantic attraction (Gottfried and Dolan, 2003). The
color of the roses also plays a role in influencing emotional responses, with
red roses associated with passion and desire (Gottfried and Dolan, 2003;
Li et al., 2006).

.
Lavender
Lavender is well-known for its calming and soothing properties
(Shamabadi et al., 2023). The scent of lavender has been shown to reduce
stress and anxiety making it a popular choice for aromatherapy (Donelli et
al., 2019; yagyu, 1993). Lavender flowers are often associated with
relaxation and improved sleep quality (Karan, 2019).
Sunflowers
Sunflowers are renowned for their vibrant appearance and the symbolism
of positivity and optimism they convey. The sight of sunflowers can elevate
mood, evoke feelings of happiness, and remind individuals of the beauty
in life (Mathews et al., 2009).
Orchids
Orchids are admired for their elegance and exotic allure. These flowers are
often associated with luxury and sensuality. Orchids can inspire feelings of
sophistication and charm, contributing to an enhanced sense of self-
esteem (Connell, 2004) .
Lily
Lily of the Valley is cherished for its delicate appearance and sweet
fragrance. The scent of these flowers is linked to nostalgia and fond
memories, making them capable of evoking sentiments of happiness and
comfort (Chi et al., 2019).
Jasmine
Jasmine flowers are revered for their enchanting fragrance, which has
been shown to have mood-lifting and anxiety-reducing effects (Xiong et al.,
2023). The aroma of jasmine can induce a sense of calmness and
tranquility (yagyu, 1993).
Chrysanthemums
Chrysanthemums are often associated with longevity and joy. These
flowers are known to radiate positive energy and can help uplift spirits. In
some cultures, chrysanthemums are symbolic of happiness and
abundance (Hadizadeh et al., 2022).
Peonies
Peonies are celebrated for their lush appearance and gentle fragrance.
These flowers can evoke feelings of compassion, femininity, and a sense of
being nurtured (Zhao and Wu, 2019).
Daisies
Daisies are simple yet charming flowers that symbolize purity and
innocence. The sight of daisies can bring about feelings of cheerfulness and
childlike wonder (Mochizuki-Kawai et al., 2020).
Marigolds
Marigolds are often associated with celebration and joy. Their bright
colors and distinct aroma can stimulate feelings of enthusiasm and
playfulness (Addington et al., 2019; Blonsky et al., 2012).
2. METHODS
For the preparation of this review, various sources were used to study the
recent trends and advancements. To acquire present knowledge regarding
the impact of different flowers on human psychology, an examination of
research papers, articles, and case studies was performed. The outcomes
were systematically arranged and presented in a well-structured manner,
aiming to offer a comprehensive grasp of the topic at hand.
3. RESULT AND DISCUSSION
The review paper explores the psychological effects of various flowers on
human well-being and emotions. The study examines a wide range of
literature to assess how different types of flowers influence mood, stress
levels, and overall psychological state in individuals. The review presents
a comprehensive analysis of the existing research on the subject,
highlighting the diverse ways in which flowers can impact human
psychology. It identifies common themes across studies, such as the
positive influence of floral scents on reducing stress and anxiety, as well
as the potential role of visual aesthetics in enhancing mood.
The paper also discusses the significance of cultural and personal
associations with certain flowers, shedding light on how individual
experiences can shape emotional responses. Moreover, the potential
variations in psychological responses, emphasizing the need for further
investigation in these areas.
Furthermore, the review paper underscores the importance of utilizing
the findings in practical settings. It suggests that incorporating flowers
into indoor environments, workplaces, and healthcare settings could
potentially contribute to creating more positive and calming atmospheres
4. CONCLUSION
Flowers, beyond their aesthetic appeal, possess a remarkable capacity to
influence human psychology and emotions. From enhancing mood to
promoting relaxation and well-being, their impact is multifaceted and has
implications across various domains. As we continue to uncover the
intricate connections between flowers and human psychology, their
therapeutic potential in diverse settings becomes increasingly evident.

Abstract: Background: The purpose of this study is to explore the differences and similarities of EEG -based neural emotional response toward flower arrangements (FAs) between the normal elderly (NE) and cognitively impaired elderly (CIE) in arranging flowers. Methods: The study participants included 16 elderly individuals: eight elderly people with normal cognitive function and eight elderly people with cognitive dysfunction. They were divided into two groups to arrange flowers, and six mood indicators (Engagement, Excitation, Focus, Interest, Relaxation and Stress) were measured with EEG before and after the experiment. Results: The similarities were that there was no significant difference in Excitement, Relaxation and Stress between pre-test and post-test for NE and CIE. The differences were that there was a significant difference on Engagement and Interest in CIE, and they both increased, but there was no difference with respect to them in NE. While there was a significant difference on the Focus of NE, it was decreased, but there was no difference for it with respect to CIE. Conclusions: A similarity on EEG-Based Neural Emotional Responses to flower arrangements between NE and CIE was that they both felt relaxation. The differences were that the Focus of NE decreased and the Interest and Engagement of CIE increased. CIEs were more interested and engaged in FAs.

Multiple previous studies have reported that viewing natural scenery supports recovery from psychological stress. Viewing flowers is thus predicted to provide a recovery effect similar to that of viewing natural scenery. It remains unclear, however, how effectively viewing flowers promotes recovery and how the practice affects the brain. Using psychological, physiological, and neuroscientific techniques, we investigated the process through which viewing flowers regulates emotion. We found that passive viewing of a typical flower image downregulated negative emotions and decreased both elevated blood pressure and cortisol levels, which are two signs of stress-induced sympathetic activation, in response to an acute visual stressor (negative images). Using functional magnetic resonance imaging (MRI), we examined brain-activation patterns relevant to emotion regulation with automatic distraction upon viewing the typical flower image. We demonstrated that activation of the right amygdala–hippocampus region was decreased during viewing of this image in comparison to viewing a flower-mosaic or a visual fixation point after an acute visual stressor. Our results suggest that viewing a flower may induce automatic distraction from a stressor and lead to a reduction in amygdala–hippocampus activation and negative emotion, thereby downregulating physiological responses.

There is a close relationship between urban green space and the physical and mental health of individuals. Most previous studies have discussed the impact of the structure of green space and its elements. This study focused on the emotional changes caused by common behaviors in urban green space (walking and sitting). We recruited 40 college students and randomly assigned them to walking and sitting groups (20 students per group). The two groups performed the same 8-min high-pressure learning task indoors and then performed 8-min recovery activities in a simulated urban green space (a bamboo-lawn space). We used the Emotiv EPOC+ EEG headset to dynamically measure six neural emotional parameters: “engagement,” “valence,” “meditation,” “frustration,” “focus,” and “excitement.” We conducted a pretest and posttest and used analysis of covariance (ANCOVA) to analyze the posttest data (with the pretest data as covariates). The results of the comparison of the two behaviors showed that the “valence” and “meditation” values of the walking group were higher than those of the sitting group, which suggests that walking in urban green space is more favorable for stress reduction. The sitting group had a higher “focus” value than did the walking group, which suggests that sitting in urban green space is better for attention restoration. The results of this study can provide guidance for urban green space planning and design as well as health guidance for urban residents.

The history of Persian gardens goes back to a few millennia before the emergence of Islam in Iran (Persia). Designs of Persian gardens have influenced and are used extensively in the gardens of Al-Andalus in Spain, Humayun’s Tomb and the Taj Mahal in India, and many gardens in the United States and other countries around the globe. Bagh in the Persian language (Farsi) means garden and the word Baghdad (the capital city of Iraq) is rooted from the words bagh and daad (meaning “the garden of justice”). Pasargadae, the ancient Persian capital city, is the earliest example of Persian garden design known in human civilization as chahar bagh or 4-fold garden design. Bagh-e-Eram, or Garden of Eden or Eram Garden, is one the most attractive Persian gardens and is located in Shiraz, Iran. There are numerous other urban ancient gardens in Iran, including Bagh-e-Shahzadeh (Shazdeh), meaning “The Prince’s Garden” in Mahan, Golestan National Park near the Caspian Sea; Bagh-e-Fin in Kashan; Bagh-e-El-Goli in Tabriz; and Bagh-e-Golshan in Tabas. The design of each Persian garden is influenced by climate, art, beliefs, poetry, literature, and romance of the country and the region where the garden is located. In addition, each garden may have a gene bank of fruits, flowers, herbs, and vegetables. Although countless gardens were destroyed in the hands of invaders throughout the centuries, Persians have attempted either to rebuild or build new gardens generation after generation, each of which has become a favorite destination to tourists from around the world.

Abstract Background Observing plants can induce neurophysiological responses that can alleviate stress and reduce anxiety. However, few studies have examined such effects in older adults. Methods The physiological and psychological effects of observing nature (visual observation of a money plant) on 50 older Chinese women (age range: 58–90 years, SD: 8.5 years) were investigated. The participants observed a healthy money plant in a planter for 5 min; the lack of presence of a plant was used as a control. Physiological measurements were assessed using electroencephalography, and the STAI was used as a psychological assessment. Results After a 5‐min observation of a money plant as compared with the control condition, systolic blood pressure significantly decreased, variations in both high alpha and high beta brainwaves were found, and psychological measurements revealed lower anxiety scores. Conclusions Our findings indicate that viewing a money plant for 5 min may enhance both psychological and physiological relaxation in older adults.

Introduction Aromatherapy and decoctions of lavender have been traditionally used for their anxiolytic harboring-soothing effects without proper evidence. This study aims to systematically identify and appraise systematic reviews on the anxiolytic effects of Lavandula angustifolia (lavender). Methods The study protocol was published in PROSPERO (CRD42021279573). ISI Web of Science, Scopus, PubMed, Embase, Cochrane Library, CINAHL, Google Scholar, and PROSPERO were searched up to August 2022 without any limitation for systematic reviews studying the anxiolytic effects of lavender in humans. The report from each study as whether or not lavender was anxiolytic was considered the primary outcome. The AMSTAR II was utilized for the quality assessment. Results Thirty systematic reviews met the inclusion criteria, fifteen of which conducted meta-analyses. All studies were published after 2010 and reported promising effects through different methods of lavender administration—namely: inhalation, massage, and oral routes—on anxiety relief. Oral doses of 80 mg and 160 mg were both effective, the higher dose being more efficient. The studies were conducted on various subjects, including preoperative patients, cardiovascular patients, hemodialysis patients, cancer patients, dental patients, and women in pre-labor. When assessed by AMSTAR II, four studies were of high quality, one had medium quality, and the rest were of low or critically low quality. No major adverse event was reported. Conclusions Lavender has shown promising potential for anxiety in various settings. Lavender was effective when inhaled, used as a massage oil, or taken orally. The oral route was the preferred long-term option and inhalation was recommended for the short term.

Chrysanthemum is a dicotyledonous genus belonging to the family Asteraceae. These herbaceous annual or perennial plants originated in East Asia and are of great ornamental, medicinal, environmental and industrial values. Chrysanthemum is amongst the most valuable floricultural crops in the world, and is extremely popular for its wide range of flower color and structure. The Chrysanthemum species have long been praised in traditional Chinese medicine history, and continue to be used as valuable drugs, food additives or herbal teas. Various phytochemical compounds, including flavonoids, terpenoids, polysaccharides and unsaturated fatty acids have been identified in the genus Chrysanthemum. This genus has also displayed multiple biological features including antioxidant, antimicrobial, anti-inflammatory, anticancer, anti-allergic, anti-obesity, immune regulation, hepatoprotective and nephroprotective activities. In the present review, we aim to extensively investigate the therapeutic potential, phytochemistry and pharmacological activities of the genus Chrysanthemum with a particular focus on the introduction of the new isolated compounds through summarizing scientific evidence released in a period of ten years (2010–2020). The taxonomic characteristics, distribution, horticultural and traditional uses of this genus are also presented. Moreover, research gaps in pharmacological and phytochemical studies, as well as future opportunities for medicinal exploitation of the genus Chrysanthemum have been discussed.

Objective To investigate the effectiveness of lavender oil (Lavandula angustifolia Mill) inhalation on anxiety, mood, and vital signs (blood pressure, respiratory rate, heart rate, and saturation) of patients undergoing oral surgery. Vital signs were considered as primary outcome measures. Paired anxiety tests were used as secondary outcome measures. Methods Patients who had dental anxiety according to the Dental Anxiety Questionnaire (DAQ) were enrolled in the study. One hundred twenty-six patients who were undergoing wisdom tooth removal under local anaesthesia were randomly assigned to the lavender oil and control groups. Paired anxiety tests (Modified Dental Anxiety Scale and State-Trait Anxiety Inventory–State Scale were performed. Vital signs were noted pre-, intra-, and post-operatively. Visual analogue scale (VAS) results were assessed. The patients' degree of satisfaction was noted. Results Pre-operative anxiety levels were similar in both groups. Significant changes in blood pressure were observed in the lavender oil group post-operatively (p < .05). Most (79.4%) of the patients in the lavender oil group enjoyed the scent, 89.68% were satisfied with their experience, and 97.62% of the patients stated that they would prefer the same protocol when needed. Conclusion Inhalation of lavender oil, which is one of the most powerful anxiolytic essential oils, reduces peri-operative anxiety and can be prospectively considered in future studies for its potential sedative characteristics in patients undergoing surgical procedures under local anaesthesia.
