Black Cohosh
An herb that is commonly used to relieve symptoms of menopause, such as hot flashes and night sweats.
Also known as: Actaea racemosa • Cimicifuga racemosa
Overview
Black cohosh (Actaea racemosa) is a flowering plant native to North America. It has a long history of use in traditional Native American medicine for a variety of ailments, particularly for women's health issues. Today, black cohosh is most commonly used to relieve symptoms of menopause, such as hot flashes, night sweats, and vaginal dryness. The exact mechanism by which black cohosh works is not fully understood, but it is believed to have an effect on estrogen receptors in the body. Some studies have shown that black cohosh can be as effective as hormone replacement therapy (HRT) in relieving menopausal symptoms, but without the associated risks. In addition to its use for menopause, black cohosh has also been studied for its potential to relieve symptoms of premenstrual syndrome (PMS) and to induce labor. However, more research is needed in these areas.
