　　Black cohosh is an herb that comes from the root or underground stems of a tall plant in the buttercup family. Black cohosh is sometimes called bugbane. American Indians used it for a number of women's health conditions, including monthly menstrual pain.

　　Some women today have continued the tradition. They use the herb to help fight unpleasant conditions at the end of their reproductive years. These include difficulty sleeping at night and hot flashes, or sudden hot sweats.

The same is true of women with breast cancer and patients with liver problems. Should signs of liver disease develop, people should stop taking black cohosh and contact a doctor.
