Commercial preparations are used to treat female conditions (dysmenorrhea): uterine spasms (cramps), menstrual pain, hot flashes, mild depression, vaginal apathy, menopause. Traditional uses for fever, arthritis and insomnia. Estrogenic effect reduces luteinizing hormone levels. A recent study of the use of Remifemin, a proprietary Black Cohosh extraction (See Friede and Liske, et.al. Obstet Gynecology. 2005;105:1074-1083) significantly reduced hot flashes, atrophy, and psyche disturbances in a trial group from 304 postmenopausal women. Results confirmed efficacy and tolerability of ispropanolic extract of black cohosh. Forty six percent of breast cancer survivors who received a black cohosh preparation were symptom free of hot flashes, sweating and other symptoms of anxiety and sleep disturbances related to premenopausal breast cancer treatment (see Jacobson, Journal Clinical Oncology; 19(10):2739-2745. 2001). A 2003 study showed an increase of bone formation in postmenopausal women (see Wuttke, et.al. Maturitas; 44(suppl 1); S 67-S 77. 2003).
Chemistry:Triterpene glycosides: acetin, cimicifugoside. Also isoflavonoids: formononetin, Formononetin binds to estrogen receptor sites and is active. The combination of estrogen effect and lowered luteinizing hormone secretions may account for its activity.
