Black cohosh has been widely used in northern Europe for more than 2 decades and has recently become popular in North America. It is the extract of the root of the black cohosh plant that is supposed to have the potent ingredients.
However, even the European data indicates that Black cohosh does not work in all women and even today, there are no scientific data on its clinical benefits. However, the product is safe when taken for short periods only.
The North American Menopause Society does supports short-term use of black cohosh for treating menopausal symptoms because it seems to have a low risk of side effects when used for up to six months. However, the long-term effects of black cohosh remain unknown. Some recent studies have found that the herb does not reduce hot flashes any better than a placebo. Recent data indicate that excess ingestion of this plant can lead to serious liver damage.
Bottom line: Many anecdotal reports exist that black cohosh works but there are no scientific studies that back up these claims. Best advice is find something else for your hot flashes- damage to your liver is not fun and can mess up your life for good!
