More than two centuries ago, Native Americans discovered that the root of the black cohosh plant (Cimicifuga racemosa) helped relieve menstrual cramps, and symptoms of menopause including hot flashes, irritability, mood swings, and sleep disturbances. Today, the roots of black cohosh are still often used for these purposes. In fact, the herb has been widely used for more than 40 years in Europe and is approved in Germany for premenstrual discomfort, painful menstruation, and menopausal symptoms.
A dozen studies or more conducted throughout the 1980s and 1990s confirm that the long-standing use of black cohosh for menopausal symptoms has scientific validity. For example, in a German study involving 629 women, black cohosh improved physical and psychological menopausal symptoms in more than 80% of the participants within four weeks. In a second study, 60 menopausal women were given black cohosh extract, conjugated estrogens, or diazepam (a leading anti-anxiety medication) for three months.
Those who received black cohosh reported feeling significantly less depressed and anxious than those who received either estrogens or diazepam. In another study, 80 menopausal women were treated for 12 weeks with black cohosh extract, conjugated estrogens, or placebo. Black cohosh improved anxiety, menopause and vaginal symptoms. In addition, the number of hot flashes dropped from 5 to less than 1 average daily occurences in the black cohosh group compared to those taking estrogen in whom hot flashes dropped from 5 to 3.5 daily occurences.
Hot Flashes with treatment for Brest Cancer
Many breast cancer patients use black cohosh to ease hot flashes, a common side effect of medications used to treat breast cancer such as tamoxifen. While black cohosh may reduce the number and intensity of hot flashes in breast cancer patients, two well-designed studies recently concluded that the herb is no more effective than placebo.
