A pilot study on the effects of a Chinese herbal preparation on menopausal symptoms

This study was conducted to determine whether a particular Chinese medicinal preparation is effective in alleviating menopausal symptoms. Chinese women with menopausal symptoms were recruited to receive treatment for 3 months followed by 3 months without treatment. The severity of menopausal symptoms and serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol levels were assessed at baseline, 3 and 6 months. Data from 97 women with a mean age of 52.3 years were analyzed. Sixty women (62%) were postmenopausal. The serum FSH level (interquartile range) was 58.0 (39.5-72.4) IU/l at baseline and rose significantly 3 months after treatment. The difference remained significant in the postmenopausal group while there was no significant difference in the perimenopausal women. The changes in serum LH and estradiol levels remained unchanged. The baseline menopausal symptom score was 8.9 +/- 6.0. The menopausal symptom score improved markedly after treatment and remained at the same level at 6 months. All individual menopausal symptoms improved significantly after 3 months of treatment except dry eye. Most of these symptoms remained significantly improved at 6 months compared with the pre-treatment assessment. We observed that the Chinese medicinal preparation used in this study is effective in improving menopausal symptoms in healthy Chinese women. Further randomized controlled trial will be needed to confirm this observation.
