No studies exist on long-term safety of black cohosh use in humans. In a transgenic mouse model of cancer, black cohosh did not increase incidence of primary breast cancer, but increased metastasis of pre-existing breast cancer to the lungs.
Liver damage has been reported in a few individuals using black cohosh, but many women have taken the herb without reporting adverse health effects,and a meta-analysis of several well-controlled clinical trials found no evidence that black cohosh preparations have any adverse effect on liver function. Despite a lack of conclusive evidence for a link between black cohosh and liver damage,
Australia has added a warning to the label of all black cohosh-containing products, stating that it may cause harm to the liver in some individuals and should not be used without medical supervision.Other studies conclude that liver damage from use of black cohosh is unlikely, and that the main concern over its safe use is lack of proper authentication of plant materials and adulteration of commercial preparations with other plant species
