Where will Black Cohosh Extract used to

1. 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. Given these examples, and results of other studies, some experts have concluded that black cohosh may be a safe and effective alternative to estrogen replacement therapy (ERT) for women who cannot or will not take ERT for menopause.

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. In addition, although there is some debate about this, black cohosh may contain plant based estrogens, called phytoestrogens. Therefore, there is some concern that if there are phytoestrogens in black cohosh, they may stimulate the growth of breast tumors. This idea has not been substantiated scientifically; in fact, some studies suggest that black cohosh may inhibit the growth of breast cancer cells in test tubes. Additional research is needed before conclusions can be drawn about use of black cohosh in women with a history of or risk for developing breast cancer (such as strong family history).

2. Arthritis & Osteoporosis

Preliminary studies also suggest that black cohosh may help reduce inflammation associated osteoarthritis and rheumatoid arthritis. In a review of scientific studies, researchers concluded that a combination of black cohosh, willow bark (Salix spp.), sarsaparilla (Smilax spp.), guaiacum (Guaiacum officinale) resin, and poplar bark (Populus tremuloides) may help relieve symptoms of osteoarthritis.
