Note: Blue cohosh (Caulophyllum thalictroides) should not be confused with black cohosh (Cimicifuga racemosa), an over-the-counter herbal supplement sold as a menopause and menstrual remedy.

Mechanism of Action

Pharmacology:

  • Constituents: The constituents of blue cohosh (Caulophyllum thalictroides) include methylcytisine, N-methylcytisine, thalictroidine, aporphine, sparteine, the saponins caulosaponine and caulophyllosaponine, as well as alkaloids, taspine, magnoflorine, anagyrine, baptifoline, 5,6-dehydro-alpha-isolupanine, alpha-isolupanine, and lupanine.4,3,1,2
  • Carcinogenic effects: Blue cohosh (Caulophyllum thalictroides) has been evaluated in vitro for its cytotoxic effects on human liver cancer cell lines.5
  • Labor induction effects: There have been at least ten chemical compounds isolated from the blue cohosh plant.3,4,2,1 The glycosides caulosaponin and caulophyllosaponin, and the chemical sparteine, which are constituents of the blue cohosh plant, have been shown to have labor induction properties.1 Caulosaponin and caulophyllosaponin have increased the rate and degree of uterine contraction for up to 90 minutes in vitro and in vivo.1 The chemical sparteine, has been used in the past as a drug to induce labor.

Pharmacodynamics/Kinetics:

  • Insufficient available evidence.
