Abstract
Women face a significant change in their reproductive health as menopause sets in. It is marred with numerous physiological changes that negatively impact their quality of life. This universal, transition phase is associated with menopausal and postmenopausal syndrome, which may spread over 2-10 years. This creates a depletion of female hormones causing physical, mental, sexual and social problems and may, later on, manifest as postmenopausal osteoporosis leading to weak bones, causing fractures and ultimately morbidity and mortality. Menopausal hormone therapy generally encompasses the correction of hormone balance through various pharmacological agents, but the associated side effects often lead to cessation of therapy with poor clinical outcomes. However, it has been noticed that phytotherapeutics is trusted by women for the amelioration of symptoms related to menopause and for improving bone health. This could primarily be due to their reduced side effects and lesser costs. This review attempts to bring forth the suitability of phytotherapeutics/herbals for the management of menopausal, postmenopausal syndrome, and menopausal osteoporosis through several published research. It tries to enlist the available botanicals with their key constituents and mechanism of action for mitigating symptoms associated with menopause as well as osteoporosis. It also includes a list of a few herbal commercial products available for these complications. The article also intends to collate the findings of various clinical trials and patents available in this field and provide a window for newer research avenues in this highly important yet ignored health segment.

Abstract
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.

Abstract
Genistein is an isoflavone first isolated from the brooming plant Dyer's Genista tinctoria L. and is widely distributed in the Fabaceae family. As an isoflavone, mammalian genistein exerts estrogen-like functions. Several biological effects of genistein have been reported in preclinical studies, such as the antioxidant, anti-inflammatory, antibacterial, and antiviral activities, the effects of angiogenesis and estrogen, and the pharmacological activities on diabetes and lipid metabolism. The purpose of this review is to provide up-to-date evidence of preclinical pharmacological activities with mechanisms of action, bioavailability, and clinical evidence of genistein. The literature was researched using the most important keyword "genistein" from the PubMed, Science, and Google Scholar databases, and the taxonomy was validated using The Plant List. Data were also collected from specialized books and other online resources. The main positive effects of genistein refer to the protection against cardiovascular diseases and to the decrease of the incidence of some types of cancer, especially breast cancer. Although the mechanism of protection against cancer involves several aspects of genistein metabolism, the researchers attribute this effect to the similarity between the structure of soy genistein and that of estrogen. This structural similarity allows genistein to displace estrogen from cellular receptors, thus blocking their hormonal activity. The pharmacological activities resulting from the experimental studies of this review support the traditional uses of genistein, but in the future, further investigations are needed on the efficacy, safety, and use of nanotechnologies to increase bioavailability and therapeutic efficacy.

Abstract
OBJECTIVES Estrogen deficiency causes various health problems in postmenopausal women, including osteoporosis. Phytoestrogen emerged as a potential alternative of estrogen with minimum side effects. The aims of this study were to analyze the metabolite profiling results of various extract of Chyrsophyllum cainito L. leaves, which contain phytoestrogen, through in silico study against 3OLS protein, an X-ray protein of ERβ, so it can predict the types of the phytoestrogen contents which have antiosteoporosis property. METHODS In silico analysis was carried out for the compounds from the metabolite profiling data of C. cainito leaves from our previous study. The structure compounds from metabolite profiling results of various extract of C. cainito leaves were prepared with Avogadro 1.0.1 software, molecular docking was done using PyRx 0.8 software, and Biovia Discovery Studio Visualizer 2016 software was used to visualize the structure of compounds against 3OLS protein. The physicochemical characteristics of the compounds were analyzed using the SwissADME web tool. RESULTS From in silico studies, it was known that there were total 11 compounds in C. cainito leaves that predicted as phytoestrogens which have ERβ agonist properties against 3OLS protein. The ERβ agonist was a compound that has parameters similar to 17β-estradiol in its interaction with 3OLS protein, which has a pharmacophore distance of 10.862 Å, and binding to amino acids His 475 and Glu 305 or Arg 346 at receptor-ligand docking simulation. CONCLUSIONS C. cainito leaves contain 11 compounds that are predicted to be phytoestrogens with ERβ agonist properties, which is responsible for antiosteoporosis activity.

Abstract
AIMS The reduced production of ovarian hormones is considered to be the cause of an increase in the incidence of heart disease in women after menopause. Phytoestrogens are found in various herbal sources and are considered as an alternative to hormone therapy because of structural similarity with oestrogen. Elaeagnus angustifolia L., known as Senjed in Persian, is used in Iranian traditional medicine with various medicinal properties, contains valuable compounds, including two types of phytoestrogens. The aim of the present study was to investigate the efficacy of E. angustifolia fruit on the cardiovascular function, lipid and glycaemic profiles in postmenopausal women. METHODS In this double-blind placebo-controlled clinical trial, 58 postmenopausal women were randomly assigned into two experimental groups of medicinal herb (15 g/day of the whole E. angustifolia fruit powder) and placebo (15 g/day of isomalt + corn starch). Before the trial and after 10 weeks of the treatment, cardiovascular function (heart rate, blood pressure), serum glycaemic profile (fasting blood glucose; glycated haemoglobin, HbA1C), insulin and lipid profile (total cholesterol, TC; triglyceride, TG; LDL-C and HDL-C) were measured. RESULTS Heart rate, and serum level of LDL-C and HDL-C significantly decreased after treatment with E. angustifolia. Changes in glycaemic profile were not clinically significant. In addition, some studied biochemical parameters significantly changed in the placebo group. CONCLUSIONS E. angustifolia was somewhat effective in improving cardiovascular function and lipid profile, as well as the overall health of postmenopausal women. However, the use of isomalt and corn starch in menopausal women needs further investigation.

Abstract
Background Phytoestrogens have a high potential to overcome the neuroinflammation caused by estrogen deficiency. Marsilea crenata Presl. is a plant known to contain phytoestrogens. This research aimed to report the activity of a 96% ethanol extract of M. crenata leaves in inducing activation of microglia HMC3 cell to M2 polarity, which has anti-inflammatory characteristics. Methods The study was done by culturing microglia HMC3 cell in 24-well microplate and inducing it with IFN-γ for 24 h to activate the cell to M1 polarity, which has proinflammatory characteristics. The 96% ethanol extract was added with various doses of 62.5, 125, and 250 ppm. Genistein, 50 μM, was used as a positive control. The analysis of the immunofluorescence of Arginase-1 (Arg1) and ERβ as markers was done using a convocal laser scanning microscope. Results The result of Arg1 shows a significant difference in Arg1 expression in the microglia HMC3 cell line between the negative control and all treatment groups at p < 0.05, with the best result at 250 ppm, whereas for ERβ, the results show, at doses of 125 and 250 ppm, that the 96% ethanol extract of M. crenata leaves decrease the activated ERβ expression at p < 0.05, with the best result at 250 ppm. The Arg1 and activated ERβ expression have a weak negative relationship with the Pearson correlation test. Conclusions The 96% ethanol extract of M. crenata leaves has an antineuroinflammation activity through the induction of Arg1 and activated ERβ expression in microglia HMC3 cell, with the best dose at 250 ppm.

Abstract
Isoflavones can exert their action on various levels: on cardiovascular system, bone and muscle health, on cancer, on menopausal symptoms, on obesity, on thyroid and on cognitive function. The aim of this systematic review is to evaluate the multidimensional effects of phytoestrogens in postmenopausal woman, and specifically to explore the impact on scientific literature. A research strategy was planned on PubMed and Scopus by defining the following key words:: menopause, climacteric, soy, isoflavone, phytoestrogens, cardiovascular system, bone mineral density, muscle mass, cancer, thyroid, obesity, cognitive. A total of 43 studies (in humans) were retrieved. The majority (12) describe the applications of soy isoflavones on cardiovascular disease, followed by effects on bone and muscle health (9), and studies concerning their action on menopausal symptoms (7), on cancer (6), on obesity (4), on cognitive function (3) and on thyroid function (2). The citation analysis revealed a growing interest for this topic and the papers on thyroid function are the most cited. Citation trends of the articles regarding the action on cardiovascular disease and on obesity are growing in the last years. Concerning the research areas, this review has assessed the effectiveness of various activities of isoflavones on welfare of menopausal women. In particular, literature show that a specific dosage of isoflavones reduces cardiovascular disease (from 20 to 100 mg/die), may be protective in osteoporosis and muscular fatigue (from 20 to 80 mg/die), may be useful for cancer prevention on endometrium, mammary glands and liver (from 50 to 100 mg/die), might improve menopausal symptoms, particularly in reducing the frequency of hot flashes (from 50 to 120 mg/die), can reduce abdominal fat and circulating inflammatory markers (from 80 to 160 mg/die), may ameliorate the possible interaction between endogenous estrogen and thyroid function (75 mg/die) and improve visual memory (from 50 to 100 mg/die).

Abstract
The aim of the authors in this randomized controlled study was to assess the effect of exercise and nutrition education on quality of life and early menopausal symptoms. This trial was conducted in east Azerbaijan Province, Iran, during the period from 2013 to 2014 with 108 women allocated into one of four groups (n = 27 in each group) by block randomization. The interventions received by the three intervention groups were: nutrition education, aerobic exercise, or exercise plus nutrition education. The control group did not receive any intervention. The Greene and MENQOL menopause symptom scales were completed before and at 8 and 12 weeks after the intervention. The mean Greene score was significantly lower than the control group in the exercise (adjusted mean difference: -5.1) and exercise plus nutrition groups (-8.0) at the end of week 8 and in the nutrition (-4.8), exercise (-8.7), and exercise plus nutrition (-13.2) groups at the end of week 12. Also, the mean MENQOL score was significantly lower than the control group in the exercise (-8.3) and exercise plus nutrition groups (-13.8) at the end of week 8 and in the nutrition (-6.6), exercise (-13.5), and exercise plus nutrition (-22.1) groups at the end of week 12. Nutrition education with aerobic exercise can improve quality of life.

Abstract
Osteoporosis is an age-related disorder that affects both women and men, although estrogen deficiency induced by menopause accelerates bone loss in older women. As the demographic shifts to a more aged population, a growing number of men and women will be afflicted with osteoporosis. Since the current drug therapies available have multiple side effects, including increased risk of developing certain types of cancer or complications, a search for potential nonpharmacologic alternative therapies for osteoporosis is of prime interest. Soy isoflavones (SI) have demonstrated potential bone-specific effects in a number of studies. This article provides a systematic review of studies on osteoporotic bone loss in relation to SI intake from diet or supplements to comprehensively explain how SI affect the modulation of bone remodeling. Evidence from epidemiologic studies supports that dietary SI attenuate menopause-induced osteoporotic bone loss by decreasing bone resorption and stimulating bone formation. Other studies have also illustrated that bone site-specific trophic and synergistic effects combined with exercise intervention might contribute to improve the bioavailability of SI or strengthen the bone-specific effects. To date, however, the effects of dietary SI on osteoporotic bone loss remain inconclusive, and study results vary from study to study. The current review will discuss the potential factors that result in the conflicting outcomes of these studies, including dosages, intervention materials, study duration, race, and genetic differences. Further well-designed studies are needed to fully understand the underlying mechanism and evaluate the effects of SI on osteoporosis in humans.

Abstract
The frequent use of plant-based products to promote health leads to the search for scientific information related to efficacy and safety of those products for human consumption. Two alfalfa-derived products (ADP), freeze-dried juice (FDJ) and dehydrated powder (DP), from alfalfa harvested in Mexico, are being developed as new possible nutraceuticals. To the best of our knowledge, any study reports the real composition of such products used to prepare instant beverages in what concerns isoflavone contents. Seven isoflavones (glycitein, formononetin, biochanin A, daidzein, genistein, daidzin and genistin) were assessed by HPLC-DAD analysis as well as its variation in five different batches of these products. Different solvents were tested in order to choose the best one to extract isoflavones. The results showed the presence of daidzein, genistein, genistin and daidzin in most samples while glycitein, formononetin and biochanin A were not detected. Significant differences between isoflavone contents were found with different solvent systems. Water was the best option to extract daidzein (0.40-1.08 mg per unit and 1.30-4.90 mg per unit for DP and FDJ, respectively) whereas the water-methanol-formic acid mixture was efficient to extract genistein (0.19-0.43 mg per unit and 0.15-0.72 mg per unit for DP and FDJ, respectively). In all cases, the total isoflavone content was higher in freeze-dried juices than in dehydrated powders. Genistein and daidzein were the more abundant isoflavones quantified. Further physiological and nutritional studies are needed to complete the validation of effectiveness and safety of these products.

Abstract
The prevalence of cardiovascular diseases (CVD) is rising and is the prime cause of death in all developed countries. Bioactive compounds (BAC) can have a role in CVD prevention and treatment. The aim of this work was to examine the scientific evidence supporting phenolic BAC efficacy in CVD prevention and treatment by a systematic review. Databases utilized were Medline, LILACS and EMBASE, and all randomized controlled trials (RCTs) with prospective, parallel or crossover designs in humans in which the effects of BAC were compared with that of placebo/control were included. Vascular homeostasis, blood pressure, endothelial function, oxidative stress and inflammatory biomarkers were considered as primary outcomes. Cohort, ecological or case-control studies were not included. We selected 72 articles and verified their quality based on the Scottish Intercollegiate Guidelines Network, establishing diverse quality levels of scientific evidence according to two features: the design and bias risk of a study. Moreover, a grade of recommendation was included, depending on evidence strength of antecedents. Evidence shows that certain polyphenols, such as flavonols can be helpful in decreasing CVD risk factors. However, further rigorous evidence is necessary to support the BAC effect on CVD prevention and treatment.

Abstract
Estrogen deficiency is associated with increased inflammation related periapical bone resorption. The present study aimed to evaluate the effect and intracellular mechanism(s) of estrogen on osteoprotegerin (OPG) and receptor activator of nuclear factor κB ligand (RANKL) expression in human dental pulp cells (HDPs). HDPs were treated with estradiol at a concentration of 0.1-10 μM. The results showed that estradiol induced OPG expression at both the mRNA and protein levels in a dose-dependent manner. However, no influence on RANKL expression was observed. An estrogen receptor (ER) inhibitor failed to attenuate the estradiol-induced OPG expression. Furthermore, ER-α and ER-β agonists did not simulate estradiol's effects on OPG expression by HDPs. However, a significant OPG upregulation was observed in HDPs treated with an estradiol-BSA conjugate or a GPR30 agonist. An ERK inhibitor significantly enhanced estradiol-induced OPG expression, whereas a p38 inhibitor markedly attenuated this expression. In conclusion, OPG expression by HDPs may be regulated by estradiol binding a membrane receptor and the balance between the ERK and p38 signaling pathways.

Abstract
OBJECTIVE High genistein doses have been reported to induce fluid accumulation in the uteri of ovariectomised rats, although the mechanism underlying this effect remains unknown. Because genistein binds to the oestrogen receptor and the cystic fibrosis transmembrane regulator mediates uterine fluid secretion, we hypothesised that this genistein effect involves both the oestrogen receptor and cystic fibrosis transmembrane regulator. METHODS Ovariectomised adult female Sprague-Dawley rats were treated with 25, 50, or 100 mg/kg/day genistein for three consecutive days with and without the ER antagonist ICI 182780. One day after the final drug injection, the animals were humanely sacrificed, and the uteri were removed for histology and cystic fibrosis transmembrane regulator mRNA and protein expression analysis using real-time polymerase chain reaction and Western blotting, respectively. The cystic fibrosis transmembrane regulator protein distribution was analysed visually by immunohistochemistry. RESULTS The histological analysis revealed an increase in the circumference of the uterine lumen with increasing doses of genistein, which was suggestive of fluid accumulation. Moreover, genistein stimulated a dose-dependent increase in the expression of cystic fibrosis transmembrane regulator protein and mRNA, and high-intensity cystic fibrosis transmembrane regulator immunostaining was observed at the apical membrane of the luminal epithelium following 50 and 100 mg/kg/day genistein treatment. The genistein-induced increase in uterine luminal circumference and cystic fibrosis transmembrane regulator expression was antagonised by treatment with ICI 182780. CONCLUSION Genistein-induced luminal fluid accumulation in ovariectomised rats' uteri involves the oestrogen receptor and up-regulation of cystic fibrosis transmembrane regulator expression, and these findings reveal the mechanism underlying the effect of this compound on changes in fluid volume in the uterus after menopause.

Abstract
Women have always looked for non-hormonal options to alleviate menopausal vasomotor symptoms and prevent menopausal bone loss. The use of complementary and alternative medicine for these purposes has particularly increased after the publication of the Women's Health Initiative's results suggesting that there might be more risks than benefits with hormone replacement. Phytoestrogens are plant-derived estrogens that, although less potent than estradiol, bind to the estrogen receptor and can function as estrogen agonists or antagonists. Soy isoflavones extracted from soy are the phytoestrogens most commonly used by menopausal women. Because typical Western diets are low in phytoestrogens and taking into account the general difficulty in changing dietary habits, most clinical trials in Western women have used isoflavone-fortified foods or isoflavone tablets. Although some women might experience a reduction in the frequency or severity of hot flashes, most studies point towards the lack of effectiveness of isoflavones derived from soy or red clover, even in large doses, in the prevention of hot flashes and menopausal bone loss. This article is part of a Special Issue entitled 'Phytoestrogens'.

Abstract
BACKGROUND Vasomotor symptoms, such as hot flushes and night sweats, are very common during the menopausal transition. Hormone therapy has traditionally been used as a highly effective treatment, but concerns about increased risk of some chronic diseases have markedly increased the interest of women in alternative treatments. Some of the most popular of these treatments are foods or supplements enriched with phytoestrogens-plant-derived chemicals that have estrogenic action. OBJECTIVES To assess the efficacy, safety and acceptability of food products, extracts and dietary supplements containing high levels of phytoestrogens when compared with no treatment, placebo or hormone therapy for the amelioration of vasomotor menopausal symptoms (such as hot flushes and night sweats) in perimenopausal and postmenopausal women. SEARCH METHODS Searches targeted the following electronic databases: the Cochrane Menstrual Disorders and Subfertility Group Specialised Register of randomised trials (29 July 2013), the Cochrane Register of Controlled Trials (CENTRAL; 29 July 2013), MEDLINE (inception to 29 July 2013), EMBASE (inception to 29 July 2013), AMED (1985 to 29 July 2013), PsycINFO (inception to 29 July 2013) and CINAHL (inception to 29 July 2013). Attempts were made to access grey literature by sending letters to pharmaceutical companies and performing searches of ongoing trial registers. Reference lists of included trials were also searched. SELECTION CRITERIA Studies were included if they were randomised, included perimenopausal or postmenopausal participants with vasomotor symptoms (hot flushes or night sweats), lasted at least 12 weeks and provided interventions such as foods or supplements with high levels of phytoestrogens (not combined with other herbal treatments). Trials that included women who had breast cancer or a history of breast cancer were excluded. DATA COLLECTION AND ANALYSIS Selection of trials, extraction of data and assessment of quality were undertaken by at least two review authors. Most trials were too dissimilar for their results to be combined in a meta-analysis, so these findings are provided in narrative 'Summary of results' tables. Studies were grouped into broad categories: dietary soy, soy extracts, red clover extracts, genistein extracts and other types of phytoestrogens. Five trials used Promensil, a red clover extract; results of these trials were combined in a meta-analysis, and summary effect measures were calculated. MAIN RESULTS A total of 43 randomised controlled trials (4,364 participants) were included in this review. Very few trials provided data suitable for inclusion in a meta-analysis. Among the five trials that yielded data assessing the daily frequency of hot flushes suitable for pooling, no significant difference overall was noted in the incidence of hot flushes between participants taking Promensil (a red clover extract) and those given placebo (mean difference (MD) -0.93, 95% confidence interval (CI) -1.95 to 0.10, I(2) = 31%). No evidence indicated a difference in percentage reduction in hot flushes in two trials between Promensil and placebo (MD 20.15, 95% CI -12.08 to 52.38, I(2) = 82%). Four trials that were not combined in meta-analyses suggested that extracts with high (> 30 mg/d) levels of genistein consistently reduced the frequency of hot flushes. Individual results from the remaining trials were compared in broad subgroups such as dietary soy, soy extracts and other types of phytoestrogens that could not be combined. Some of these trials found that phytoestrogen treatments alleviated the frequency and severity of hot flushes and night sweats when compared with placebo, but many trials were small and were determined to be at high risk of bias. A strong placebo effect was noted in most trials, with a reduction in frequency ranging from 1% to 59% with placebo. No indication suggested that discrepant results were due to the amount of isoflavone in the active treatment arm, the severity of vasomotor symptoms or trial quality factors. Also, no evidence indicated that these treatments caused oestrogenic stimulation of the endometrium or the vagina or other adverse effects when used for up to two years. AUTHORS' CONCLUSIONS No conclusive evidence shows that phytoestrogen supplements effectively reduce the frequency or severity of hot flushes and night sweats in perimenopausal or postmenopausal women, although benefits derived from concentrates of genistein should be further investigated.
