Comprehensive review examining all published literature pertaining to pre-clinical and clinical safety of various forms of Cimicifuga racemosa, as well as FDA and World Health Organization (WHO) adverse event reporting systems, monographs, compendia, internal unpublished data from a major manufacturer, foreign literature, and historical, anecdotal report.

·          Uncontrolled reports, postmarketing surveillance, and human clinical trials of more than 2,800 patients demonstrate a low incidence of adverse events (5.4%).

·          Of the reported adverse events, 97% were minor and did not result in discontinuation of symptoms, and the only severe events were not attributed to Cimicifuga treatemtn.

“Of 10 clinical studies, including a total of 1,371 participants, nine of these studies demonstrated positive effects for menopausal symptoms.  Numerous clinical trials with varied methods and designs have been conducted on the standardized isopropanolic/ethanolic extract of black cohosh root, Remifemin®, from 1981 to the present.”

National Institute of Health

Questions and Answers About Black Cohosh and the Symptoms of Menopause issued October 2002

“Other preparations of black cohosh have been less well studied than Remifemin® …black cohosh is used primarily for hot flashes and other menopausal symptoms.  A number of studies using various designs have been conducted to determine whether black cohosh affects the menopausal symptoms… To provide more definitive evidence on the effects of black cohosh on menopausal symptoms, NCCAM is funding a 12-month, randomized placebo controlled study to determine whether treatment with black cohosh is effective in reducing the frequency and intensity of menopausal hot flashes.”

Alternatives to Hormone Replacement Therapy: Suggestions for the North American Menopause Siciety issued July 2002

“Reseach suggests that mild hot flashes can be relieved by consuming a serving of soy foods daily or taking a supplement of black cohosh.”
