Complementary and Alternative Medicine for Menopause

The effect of Salvia officinalis extract on symptoms of flushing, night sweat, sleep disorders, and score of forgetfulness in postmenopausal women

Background:

Complications of hormone therapy (as replacement) during menopause prompted us to research on alternative therapies including herbal therapy in this regard.

Objectives:

The effect of Salvia officinalis extract on symptoms of flushing, night sweat, sleep disorders, and score of forgetfulness in postmenopausal women on Namazi Hospital Bone Density Center in Shiraz 2015.

Methods:

In a double-blind randomized controlled clinical trial, 66 postmenopausal women complaining of menopausal symptoms were divided into two groups of intervention and control, respectively. The intervention group received S. officinalis tablets (containing 100 mg S. officinalis extract), with a dose of three tablets a day for 3 months, while the control group received placebo tablets with the same prescription order. MRS (Menopause Rating Scale) and PSQI (Pittsburgh Sleep Quality Index) questionnaires were completed at the beginning and end of the study. The checklists of hot flushing and night sweating were completed a week before the intervention and at weeks 2, 4, 6, 8, 10, 12 during the intervention. Finally, the data were analyzed through SPSS₁₈ software, using paired t-test, ANOVA. A significant level of 5% was considered.

Results:

According to the paired t-test, the mean score of flushing, palpitation, sleeping disorders, muscle and joint aches, depression, nervousness, anxiety, and sexual desire and satisfaction significantly decreased by 1.6, 0.4, 1.6, 2.1, 1.4, 1.2, 1.6, and 0.8 units, respectively, in the intervention group compared to the control group (P < 0.001). Therefore, the mean score of PSQI significantly decreased by 3.8 units in the intervention group after the intervention (9.4 ± 3.7 vs 5.6 ± 1.9 (P < 0.05).

Conclusions:

Salvia extract improved menopausal symptoms such as flushing, night sweat, heart palpitations, muscle and joint pain, depression, anxiety, sleep disorders, and sexual desire.

Genistein as Potential Therapeutic Candidate for Menopausal Symptoms and Other Related Diseases

Plant-derived compounds have recently attracted greater interest in the field of new therapeutic agent development. These compounds have been widely screened for their pharmacological effects. Polyphenols, such as soy-derived isoflavones, also called phytoestrogens, have been extensively studied due to their ability to inhibit carcinogenesis. These compounds are chemically similar to 17β-estradiol, and mimic the binding of estrogens to its receptors, exerting estrogenic effects in target organs. Genistein is an isoflavone derived from soy-rich products and accounts for about 60% of total isoflavones found in soybeans. Genistein has been reported to exhibit several biological effects, such as anti-tumor activity (inhibition of cell proliferation, regulation of the cell cycle, induction of apoptosis), improvement of glucose metabolism, impairment of angiogenesis in both hormone-related and hormone-unrelated cancer cells, reduction of peri-menopausal and postmenopausal hot flashes, and modulation of antioxidant effects. Additionally, epidemiological and clinical studies have reported health benefits of genistein in many chronic diseases, such as cardiovascular disease, diabetes, and osteoporosis, and aid in the amelioration of typical menopausal symptoms, such as anxiety and depression. Although the biological effects are promising, certain limitations, such as low bioavailability, biological estrogenic activity, and effects on target organs, have limited the clinical applications of genistein to some extent. Moreover, studies report that modification of its molecular structure may eliminate the biological estrogenic activity and its effects on target organs. In this review, we summarize the potential benefits of genistein on menopause symptoms and menopause-related diseases like cardiovascular, osteoporosis, obesity, diabetes, anxiety, depression, and breast cancer.
