Black cohosh is a popular over-the-counter herbal remedy. There is some evidence that it is effective in reducing some of the symptoms of menopause, such as hot flashes and vaginal dryness, although large-scale studies of its effectiveness and possible side effects have not yet been done.

Its potential for alleviating painful menstruation and PMS, and slowing development of osteoporosis, is also being investigated, although there is as yet no firm evidence for these uses.
