Some women say that black cohosh supplements help relieve their menopausal symptoms, especially hot flushes. This may be because the root of the plant contains phytoestrogens. Phyto-oestrogens are chemicals found in plants that are similar to the female sex hormone oestrogen. You get menopause symptoms because your ovaries are no longer producing female sex hormones, such as oestrogen. Phytoestrogens in black cohosh supplements may help towards replacing the oestrogen no longer being made by the ovaries.
