Description & Growing

Black cohosh is a perennial that can reach 8 feet in height. The smooth, furrowed stem divides into thirds and the leaves are tripinnately compound with a serrated margin. The flowers appear on tall racemes, and have no petals. The rhizome is dark and knotty (Grieve, 1931/1971; Soule, n.d.)

 

It can be found in Eastern North America from Georgia to Ontario and Quebec, and from Missouri and Arkansas through the Appalachians, Pennsylvania, New York, Massachusetts.

 

Black cohosh is listed as endangered in Massachusetts and Illinois, and is on the United Plant Savers’ “At Risk” list. Only organically cultivated black cohosh should be used. Please do not harvest wild black cohosh.

 

Reminder: do not harvest from wild. Cultivated black cohosh root may be harvested in the fall after the aerial parts have died down

Safety

  • Avoid during pregnancy and while nursing.  Avoid with any heart conditions.  Excess use may cause nausea, vomiting, headache, and lower blood pressure.
  • Unlike pharmaceutical hormone replacement therapy, black cohosh is considered to be a menopause tonic that is safe for women with estrogen-dependent cancers, uterine bleeding, fibrocystic breast disease, endometriosis, liver disease, gallbladder disease, or pancreatitis.
  • One report implicated black cohosh in a case of liver failure (Nisbet and O’Connor, 2007) but it wasn’t clear if the problem stemmed from contamination or accidental substitution. Other studies suggest that black cohosh is safe if taken for a limited period (Huntley, 2004) and a systematic review of adverse events suggests that black cohosh is safe (Borrelli and Ernst, 2008). Blumenthal (2003) summarizes other findings suggesting some GI tract discomfort and if overdosed, symptoms like dizziness, headache, impaired vision and circulation may occur. Black cohosh should not be given to children.
