Black Cohosh

(Last edited: Saturday, 17 September 2016, 9:53 PM)

cimicfugaAlso Known As: Cimicifuga,

Scientific Name: Cimicifuga racemosa.

Family: Ranunculaceae.

People Use This For: Black Cohosh is used for symptoms of menopause, inducing labor in pregnant women, premenstrual syndrome (PMS), painful periods, nervous tension, indigestion, rheumatism, and as a mild sedative.

Safety: Possibly safe when used orally and appropriately. Black cohosh has been safely used in some studies lasting up to a year; 1,2,3 There is concern that black cohosh might cause liver damage in some patients. Several case reports link black cohosh to liver failure or autoimmune hepatitis; 4,5,6,7,8,9,10,11,12,13,14,15,16,17 however, there is no conclusive evidence that black cohosh is the cause of liver damage in these patients.18 Until more is known, monitor liver function in patients who take black cohosh for more than three months. Analysis of 9 Cases of Suspected association between Black Cohosh and Hepatitis concluded that there is little if any hepatotoxic risk by the use of Black Cohosh in these cases. Menopause 2009 Sep-Oct: 16(5):956-65 Teschke R, Bahre R, Fuchs J, Wolff A. It is concluded that the use of BC may not exert an overt toxicity risk, but quality problems in a few BC products were evident that require additional regulatory quality specifications. Ann Hepatology. 2011 Jul-Sep;10(3):249-59

Pregnancy and Lactation: Refer to Medical Herbalist

Effectiveness: POSSIBLY EFFECTIVE

Menopausal symptoms. Some black cohosh extracts seem to modestly reduce symptoms of menopause, such as hot flashes. However, there is considerable variability in the preparations used in clinical trials, and in the results obtained.19

INSUFFICIENT RELIABLE EVIDENCE to RATE

Osteoporosis: Preliminary clinical research suggests that postmenopausal women who take a specific black cohosh extract CR BNO 1055 (Klimadynon/Menofem, Bionorica AG) 40 mg/day have increased levels of bone-specific alkaline phosphatase (bALP), which is a marker of bone formation, after 12 weeks of treatment. 20 However, it is not known if this black cohosh extract can increase bone mineral density or decrease the risk of fracture. More evidence is needed to rate black cohosh for these uses.

Mechanism of Action: The applicable parts of black cohosh are the rhizome and root. The active constituents of black cohosh include phytosterin; isoferulic acid; fukinolic acid; caffeic acid; salicylic acid; sugars; tannins; long-chain fatty acids; and triterpene glycosides, including acetein, cimicifugoside, and 27-deoxyactein.21,22 Black cohosh has estrogen-like effects (not estrogenic effects) that are exerted by an unknown mechanism.21,23,20

Adverse Reactions: Black cohosh can commonly cause gastrointestinal upset.4,24,25 Black cohosh has associated with weakness and muscle damage in one case. In another case, a single patient developed symptoms of cutaneous pseudolymphoma 6 months after starting a specific black cohosh extract (Remifemin). Symptoms resolved within 12 weeks of discontinuing black cohosh.26 There are two case reports of cutaneous vasculitis in menopausal women who took black cohosh-containing products. In these cases, both women were taking a combination product containing black cohosh 40 mg (Estroven, Amerifit Brands). Symptoms resolved within 3 months of discontinuing the product.27 Interactions with Herbs & Supplements: Refer to a Medical Herbalist. Interactions with Drugs: Atorvastatin (Lipitor) One report of significant interaction. Chemotherapy: Refer to a Medical Herbalist. Hepatotoxic Drugs: Refer to a Medical Herbalist. Interactions with Foods: None known.

Interactions with Lab Tests: Liver Function Tests: Elevated liver function tests have not been documented in clinical trials.20 Theoretically, some patients taking black cohosh might experience elevated liver function tests.

Interactions with Diseases or Conditions: Breast Cancer: Refer to Medical Herbalist.

Hormone-Sensitive Cancers/Conditions: Black cohosh doesn't seem to affect estrogen receptors. Refer to Medical Herbalist.

Kidney Transplant: Refer to Medical Herbalist.

Liver Disease: Refer to Medical Herbalist.
