The Latin name for black cohosh is Cimifuga racemosa. Cimifuga comes from the Latin cimex (“bug”) and fugare (“to drive away”). This is related to the herb’s strong scent.

A 3rd study, involving 80 women treated for 12 weeks with black cohosh extract, showed an improvement in anxiety symptoms as well as menopause symptoms. In the group taking black cohosh, the number of hot flashes dropped from 5 per day less than 1 per day. This was a superior result to estrogen replacement therapy, where hot flashes dropped to 3.5 times a day.
