About

EMA names Cimicifuga racemosa (L.) Nutt., rhizome; NCCIH records both Actaea racemosa and Cimicifuga racemosa, part given as root or rhizome. Naming duality and part scope are open.

Forms and distinctions

Different preparations of the same material are described separately, because what is recorded for one form does not carry to another.

Dry extracts in solid oral forms. Regulator conclusions limit use to adult women.

Safety considerations

Side effects include liver problems, allergic skin reactions, swelling of face and extremities, and gut symptoms, with instruction to stop and consult a doctor immediately on symptoms suggestive of liver problems. Cases of liver damage, some very serious, have been reported in people taking products labelled as black cohosh; some commercial products have been found to contain the wrong herb or unlisted mixtures; black cohosh and blue cohosh (Caulophyllum thalictroides) are different herbs, blue cohosh being associated with serious adverse effects; safety is uncertain for women who have had hormone-sensitive conditions; use during pregnancy or breastfeeding may not be safe.
