Muscle Damage Induced by Black Cohosh (Cimicifuga Racemosa)‪.‬

Abstract Extracts of black cohosh (Cimicifuga racemosa) are commonly used for the treatment of symptoms associated with menopause. Adverse events with black cohosh are rare, mild and reversible. A few number of serious adverse events, including hepatic and circulatory conditions, have been also reported, but without a clear causality relationship. We report the case of a woman with severe asthenia and very high blood levels of creatine phosphokinase and lactate dehydrogenase. The patient referred to take a dietary supplement derived from black cohosh for ameliorating menopause vasomotor symptoms. To exclude a possible involvement of this product, the patient was suggested to discontinue this therapy. After suspicion the patient showed a progressive normalization of biochemical parameters and improvement of clinical symptoms.
