Is Black Cohosh effective?
There is some scientific evidence that black cohosh can help relieve some of the symptoms of menopause such as hot flashes after about a month of treatment. But black cohosh does not seem to help relieve hot flashes in women who have had breast cancer. There isnt enough information to know if black cohosh is effective for the other conditions people use it for, including: premenstrual syndrome (PMS), painful menstruation, upset stomach, muscle pain, fever, sore throat, cough, and as an insect repellent.
