There is no evidence of effectiveness in the alleviation of  menopausal symptoms with the use of phytoestrogen treatments
BACKGROUND Vasomotor symptoms , such as hot flushes and night sweats , are very common during the menopausal transition .
Hormone replacement therapy has traditionally been used as a very effective treatment but concerns over increased risks of some chronic diseases have markedly increased the interest of women in alternatives .
Some of the most popular of these are treatments based on foods or supplements enriched with phytoestrogens , plant-derived chemicals that have oestrogenic action .
OBJECTIVES To assess the efficacy , safety and acceptability of foods and supplements based on high levels of phytoestrogens for reducing hot flushes and night sweats in postmenopausal women .
Comparison of Pueraria lobata with hormone replacement therapy in treating the adverse health consequences of menopause
Objective Pueraria lobata ( PL ) is used as a traditional Chinese herbal remedy for menopausal symptoms , as well as an ingredient in preparations for conditions affecting menopausal women , such as osteoporosis , coronary heart disease , and some hormone-dependent cancers . The scientific basis for its action may be its action as a phytoestrogen . Design To examine the effects of PL in comparison with hormone replacement therapy ( HRT ) on lipid profile , sex hormone levels , bone turnover markers , and indices of cognitive function . For the study , 127 community-living , postmenopausal women aged 50 to 65 years were r and omized to receive HRT ( n = 43 ) , PL ( equivalent to 100 mg isoflavone ; n = 45 ) , or no treatment ( n = 39 ) for 3 months . The following measurements were carried out at baseline and after 3 months for all participants : menopausal symptoms question naire ; neuropsychological tests covering memory , attention , motor speed , and word-finding ability ; quality of life ( SF36 ) ; lipid profile ; urinary deoxypyridinoline ; dietary phytoestrogen intake and urinary phytoestrogen ; estradiol ; follicle-stimulating hormone ; and luteinizing hormone . Results Only participants in the HRT group showed a mean reduction in cholesterol and low-density lipoprotein cholesterol that was significantly different from that of the control group . No significant changes in lipid profile or follicle-stimulating hormone and luteinizing hormone were observed in the PL group compared with the controls . However , both the HRT and PL groups showed an improvement in Mini-Mental State Examination score and attention span compared with the case of participants receiving no treatment . HRT and PL had different effects on cognitive function ;  HRT improved delayed recall , whereas flexible thinking seemed improved in the PL group . Conclusions This study was unable to demonstrate a scientific basis for the use of PL for improving the health of postmenopausal women in general . However , the effect of PL on cognitive function deserves further study
