Studies on black cohosh for menopause symptoms, conducted over six-plus months in women aged 45-64, showed modest improvements in symptoms.

“Now, a few additional details about these studies, they were generally carried out on women age 45 to 64, in some cases, they look specifically at women that were clinically obese or overweight, although not always, the subject size pools are pretty big, you know, anywhere from 50 to 87, these are decent size, 132 subjects, et cetera, so these look to be like quality studies, and they basically point to the fact that black cohosh can have a modest effect in improving menopause symptoms.”
