The Effect of Lavender Aromatherapy on the Symptoms of Menopause

Comparing the Effects of Lavender Aromatherapy and Mindfulness-Based Cognitive Therapy on Sexual Function in Women in Iran

OBJECTIVE

To compare the effects of aromatherapy with lavender and mindfulness-based cognitive therapy for sexuality (MBCT-S) on female sexual function.

DESIGN

Randomized controlled trial.

SETTING

Health centers in Roudan city, Iran.

PARTICIPANTS

Sixty married women, ages 18 to 45 years, were recruited using the Female Sexual Function Index (FSFI). Participants were selected from health centers in 2022 via convenience sampling.

INTERVENTION AND MEASUREMENTS

Upon their completion of a demographic checklist and the FSFI as a pretest, participants were divided into three groups, including lavender aromatherapy (n = 20), MBCT-S (n = 20), and control (n = 20) through random selection with permutation blocks. All groups completed FSFI as a posttest. Data were analyzed by SPSS 26 using chi-square, Wilcoxon, Kruskal-Wallis, and Mann-Whitney statistical tests.

RESULTS

There was no statistically significant difference among the three groups before the intervention (p = .652), but there was a significant difference among them after the intervention (p = .001). There was a significantly positive difference between the intervention groups and the control group (p < .001). A significant relationship was observed among the three groups in sexual desire, pain, satisfaction, lubrication, and arousal. The mean scores of the posttest in sexual desire, pain, satisfaction, and lubrication were positively higher in the MBCT-S group than in the aromatherapy group, and both intervention groups showed the same effect for sexual arousal. Aromatherapy and counseling had no significant effect on improving sexual orgasm.

CONCLUSION

MBCT-S can be used to improve many aspects of female sexual function, except for orgasm disorders; aromatherapy may improve sexual arousal.

Effect of Salvia officinalis scent on postmenopausal women's sexual function and satisfaction: a randomized controlled trial

INTRODUCTION

Sexual function is one of the important aspects of quality of life which is often impaired after menopause. Given the side effects of hormone therapy on postmenopausal women, alternative treatments such as aromatherapy have won popularity. The aim of this study was to investigate the effect of aromatherapy using Salvia officinalis on the sexual function and satisfaction of postmenopausal women.

METHODS

This was a double-blind randomized controlled trial conducted on postmenopausal women referring to health centers in Kermanshah, Iran, in 2018. The participants were randomly divided into two groups: Salvia officinalis (n = 32) and control (n = 32). Women in the intervention group received 2 drops of Salvia officinalis essential oil by inhalation twice a day for 5 consecutive days of a week continued for 6 weeks. The control group received almond oil in the same dosage and frequency. Sexual function and satisfaction were evaluated using the Lindberg sexual satisfaction questionnaire and the female sexual function index, respectively before the intervention and 6 weeks after it.

RESULTS

After 6 weeks of intervention, the total mean scores of sexual function (28.8 ± 2.13 vs.17.9 ± 1.59 P < 0.001) and sexual satisfaction (71.53 ± 5.86 vs. 50.44 ± 10.41) were significantly higher in the Salvia officinalis group compared with the control group, respectively.

CONCLUSION

The findings showed that aromatherapy using Salvia officinalis has a significant effect on improving sexual function and satisfaction in postmenopausal women. Therefore, given the prevalence of sexual disorders in postmenopausal women, aromatherapy using Salvia officinalis is recommended to be used for improving these disorders.

Phytotherapic approach in menopause: light and darkness

INTRODUCTION

Menopause is a critical period of the woman life, characterized by a peculiar modification in estrogens concentration and accompanied by different signs and symptoms. To prevent and contrast unfavorable consequences of menopause, different therapeutic approaches could be evaluated. The hormone replacement therapy (HRT) is the most known, but it has several contraindications. The increasing interest in phytotherapy introduces the necessity for endocrinologist involved in menopause to suggest different therapeutic approaches, considering the state of health of patient and the real efficacy of the drugs. We aim to outline the main phytotherapy treatments to choose in menopause.

EVIDENCE ACQUISITION

This review is based on focused research of the current literature on PubMed and Scopus such as research databases. We selected 4120 papers through these keywords: "MENOPAUSE" AND "phytotherapy," "natural therapy," "phytoterapy drugs." Then, the literature was scanned selecting English papers of last 10 years (last research on October 1, 2021), excluding reviews. Separately, two researchers MGT and CP examined and read 212 full selected papers. We included clinical trials and randomized clinical trials written in English and excluded duplicates, animal studies and studies with lack of group of interest, non-relevant outcomes, inappropriate methodology. Retrospective studies, case reports, case series, original articles, brief communications, and letter to the editor were included in our research. We furthermore completed our research by the examination of every study's bibliography.

EVIDENCE SYNTHESIS

Phytotherapy involves the use of plants or plant extracts for the treatment of diseases thanks to the activities of their compounds and metabolites. In particular, many of them have an estrogen-like activity and are identified as phytoestrogens, because thanks to their chemical structure are able to bind the estrogen receptors and carry out biological estrogenic or antiestrogenic activities. The supplementing diet with these compounds can ensure an advantage on various aspects of the climacteric syndrome and some of them also have a beneficial impact on cardiovascular risk, bone health and sleep complaint. These substances can be used with safety due to their good tolerability and low rate of side effects. There are no known serious adverse events associated with their consumption, but as a precaution, its use is not recommended during pregnancy and in association with hormonal therapies or in women with hormone responsive cancers.

CONCLUSIONS

Phytotherapy must be considered an interesting tool in the treatment of signs and symptoms in selected menopause woman.

Aromatherapy for Managing Menopausal Symptoms: A Systematic Review and Meta-analysis of Randomized Placebo-Controlled Trials

Background: Aromatherapy is widely used in women's health as a complementary therapy. Objective: This review aimed to critically evaluate clinical evidence of the effectiveness of aromatherapy in managing menopausal symptoms. Design: A systematic review and meta-analysis. Methods: A total of 11 electronic databases were searched up to November 5, 2020. Randomized controlled trials (RCTs) evaluating any type of aromatherapy against placebo in menopausal individuals were eligible. Two authors independently assessed the study eligibility and risk of bias as well as extracted the data for each study. Cochrane risk of bias tool was used to evaluate the methodological quality of each included studies. No ethical approval was required for this manuscript as this study did not involve human subjects or laboratory animals. Results: Seven RCTs met our inclusion criteria and were analyzed. Most of the included RCTs had low risk of bias in most domains except for blinding. Four studies tested the efficacy of aromatherapy for menopausal symptoms. The results showed that aromatherapy (lavender or low dose of neroli) inhalation had superior effects on reducing the total menopausal symptom score compared with the placebo. One study presented that aromatherapy massage with mixed oils reduced menopausal symptoms. Three studies investigated the effects of aromatherapy inhalation on sexual desire, and all of the studies showed that aromatherapy inhalation (lavender or low dose of neroli or mixed oils) had superior effects compared with the placebo. Conclusion: This review indicates limited evidence of the benefit of aromatherapy (lavender or low dose of neroli) in improving total menopausal symptoms and sexual desire. Further studies are highly warranted to validate the findings.

Lavender essential oil on postmenopausal women with insomnia: Double-blind randomized trial

BACKGROUND

To evaluate the effect of Lavandula angustifolia essential oil inhalation on sleep and menopausal symptoms in postmenopausal women with insomnia.

PARTICIPANTS

35 postmenopausal women with a clinical diagnosis of insomnia were included, 17 in Aroma Group (AG) and 18 in Placebo Group (PG).

METHODS

In this double-blind, randomized controlled trial, PG participants inhaled sunflower oil and AG participants inhaledLavandula angustifolia essential oil, for 29 days. Both groups received sleep hygiene guidelines before the intervention and weekly follow-up during it. Evaluations were performed before and after intervention. All statistical analyses and intention-to-treat test were performed in SPSS 22. Sleep quality (Primary outcome) was measured by Pittsburgh Sleep Quality Index. Secondary outcomes were polysomnography data, severity of insomnia, anxiety and depression symptoms, and postmenopausal symptoms.

RESULTS

There were no significant differences between groups after intervention in the primary outcome (P = 0.22; effect size=0.69); however, a tendency of improvement in wake after sleep onset (WASO) was observed (P = 0.07; effect size=0.81; B = 42.2). Both groups presented better sleep quality over time (AG P < 0.001; PG P = 0.011). AG participants showed a significant decrease in sleep onset latency (P = 0.001), depression levels (P = 0.025), hot flashes (P < 0.001), postmenopausal symptoms (P < 0.001) and, in polysomnography data, increased sleep efficiency (P = 0.002) compared to baseline.

CONCLUSION

Although no significant differences were observed between groups, our data presented a tendency of improvement in WASO. Moreover, AG participants had enhanced overall sleep pattern, quality and sleep efficiency. Weekly follow-up and sleep hygiene instructions were essential for both groups to show improvement in almost all outcomes.

The antidepressant effects of lavender (Lavandula angustifolia Mill.): A systematic review and meta-analysis of randomized controlled clinical trials

BACKGROUND AND AIMS

Antidepressant drugs are accompanied with high rate of adverse effects. Lavender is one of the most common herbal drugs mentioned in Traditional Persian literature with potential efficacy on mental disorders and less serious side effects. Thus, the aim of this study was to determine the efficacy of lavender on depression severity by preforming a systematic review and meta-analysis.

METHODS

Databases including PubMed, Scopus, Cochrane library, Embase and Web of science were searched for relevant articles till December 2020. Quality of studies were evaluated by Jadad scale and the Cochrane collaboration tool. Depression as endpoint measure or as a subscale of any valid assessment tool was subjected to quantitative data analyses. Both fixed and random effects meta-analysis were conducted for data synthesis.

RESULTS

Out of 342 screened studies, 17 articles were included in the meta-analysis. Results showed significant efficacy of lavender in decreasing depression scores compared to the control group (pooled Standardized Mean Difference (SMD)= -0.66, 95 % CI: -0.85 to -0.46;P < 0.001, I² = 68.2 %;). Subgroup analysis proved that the effect of lavender was marginally more pronounced in participants with diagnosed depression (pooled SMD= -0.62, 95 % CI: -1.26 to 0.01, P = 0.055; I² = 88.1 %) while its effect was statistically significant in patients having other diseases with concomitant depressive symptoms (pooled SMD= -0.65, 95 % CI: -1.84 to -0.46, P < 0.001; I² = 52.1 %), and the oral route (pooled SMD= -0.56, 95 % CI: -1.07 to -0.05, P = 0.032; I² = 85.2 %;) was the most effective route of administration.

CONCLUSIONS

This systematic review and meta-analysis concluded that lavender has significant antidepressant effects. However, due to some limitations, further large clinical trials are recommended with more homogeneous populations and rigorous designs.
