It is approved by the German Comission E monographs for the following applications; complaints of premenstrual, heavy menstrual cycle, or climacteric origin. In one randomized, double-blind, placebo controlled comparative clinical trial, 80 women with climacteric symptoms received a standardized preparation of Black Cohosh, conjugated estrogens (.625 mg/day) or placebo for 12 weeks. At the end the patients receiving Black Cohosh had improved compared to both placebo and estrogen. Both physical (measured by the Kupperman index) and psychological (measured by the Hamilton Anxiety Scale) symptoms were significantly improved. More research is needed to fully understand the exact mechanism of activity.
