The purpose of this article is to assess recent data supporting the safety and efficacy of black cohosh products for the mitigation of menopause-related symptoms. Searches of the published literature in Napralert, Cochrane Library and PubMed databases were performed from 2003 to 2006. Information from drug regulatory agencies from five different countries was obtained to evaluate safety. While there are a few contradictory studies, the majority of the clinical trials indicate that extracts of black cohosh ( Actaea racemosa L.) improve menopause-related symptoms. However, to date, at least 50 cases of possible hepatotoxicity have been reported. Although previous safety reviews suggest that black cohosh is well tolerated, the increasing numbers of these case reports indicates that further preclinical toxicological evaluations of black cohosh are urgently needed. At this time, it appears prudent to advise menopausal women with underlying liver disease, autoimmune diseases or those taking medications that may impact liver function not to use products containing black cohosh.
