MedicinalHerbInfo.org states that black cohosh is a perennial plant indigenous to North America. It's also referred to as black cohush, black snakeroot, bugbane, bugwort, cimicifuga, rattleroot, rattleweed, richweed, snakeroot and squawroot. The rootstock is the portion of the plant used for medicinal treatments.
History
The National Institute of Health (NIH) tells of the various historical uses for black cohosh, going all the way back to the early Native Americans' use of the herb. The primary historical use for it is for gynecological disorders. But it has also historically been used for kidney disorders, malaria, rheumatism, colds, cough, constipation, hives, backache and to induce lactation. Currently, it is mainly used for gynecological health.
Medicinal Uses
According to the University of Maryland Medical Center (UMM), black cohosh is mainly used to ease the symptoms of menopause such as night sweats, hot flashes, vaginal dryness and anxiety.
The UMM web site states that many studies have supported the claims for black cohosh as a remedy for menopausal symptoms, but a few have been inconclusive. The National Center for Complementary and Alternative Medicine (NCCAM) says that there is not enough evidence to conclude that black cohosh is effective in treating menopausal symptoms.
The NIH web site details several clinical studies on the effectiveness of black cohosh in treating hot flashes and night sweats.
Forms Used
The NCCAM web site states that it is the underground roots and stems of black cohosh that are used for medicinal treatments. It is either used fresh or dried and made into tea, liquid extract or capsules.
Potential Side Effects & Contraindications
Since black cohosh is believed to have an estrogenic effect, pregnant women should not use the herb. It could potentially stimulate contractions of the uterus.
Black cohosh has been shown to have very little interaction with other medications, except for tamoxifen. If you are taking tamoxifen you should avoid the use of this herb.
There has also been some disagreement about the safety of black cohosh for women with a personal or family history of breast cancer. Consult with your health care provider if you are considering taking black cohosh.
Warning
There are not enough data to confirm the effects of black cohosh when used for a long period of time. Currently, there have only been studies of its use for up to six months.
Any new substance can cause an allergic reaction. Be sure to watch for signs of rash, hives, difficulty breathing or chest pains when using black cohosh. If you experience any of these, discontinue taking black cohosh and consult with your health care provider.
