Contraindications, Interactions, and Side Effects (Black Cohosh):
- Class 2b, 2c (AHP). No contraindications/drug interactions noted (KOM). I got a challenging letter from German parties with an economic interest in cohosh, asking where I got the cautionary remarks from in my 1985 CRC book. They must really be irritated by what follows: Commission E reports occasional gastric complaints. Not to be used for more than 6 months (AEH). With prolonged use, may irritate the
uterus, cause dizziness, diarrhea, nausea, vomiting, abdominal pain, headaches, joint pains, and lowered heart rate. Can contribute to abnormal blood clotting and liver problems. Can encourage breast tumors. Should not be used by anyone with any type of heart disease or by anyone advised not to take oral contraceptives. Women taking estrogen therapy should consult a physician before using black cohosh   (SKY). Can cause premature labor. Because of insufficient data, use during pregnancy and lactation is not advised. Should be used only under medical supervision (TMA, 1996). High doses may cause diaphoresis, dizziness, nausea, reduced pulse rate, visual disturbances, and vomiting (CAN). Because of uterine estrogen receptor binding in vitro, its use in pregnancy and lactation is to be avoided. What they say about black cohosh should be templated and said for every herb, It has been recommended that black cohosh should only be used in therapeutic doses, and that high doses are potentially dangerous (CAN). Canadian regulations do not allow black cohosh as a non-medicinal ingredient for oral use products (Michols, 1995). Pedersen is not much kinder, Such constituents as tannins, gallic acid, and pseudotannins, including isoferulic acid, and the salicylates, are irritants to the skin, lungs, and kidneys. The drastic action of the irritant principles in black cohosh are not lethal, but overdoses are characterized by nausea and headache (PED). Schulz et al. (1998) are nicer to this herb, sold in Germany and America, than the Anglos quoted above. In five studies using doses equivalent to 40 mg/day crude herb, there are no case reports of toxic effects from the herb, and there appears to be no specific toxicity associated with any of its known constituents. Two of the five showed mild side effects (dizziness, GI distress, headache, and weight gain). No other contraindications are known. The duration of use should not exceed 3 months (SHT). Cohosh extract augmented the activity of tamoxiphen (MAB). Finally, let me quote Gruenwald, editor-in-chief of the Herbal PDR, and coincidentally, also editor of the ABC Commission E translation, because the two versions differ. No health hazards or side effects are known in conjunction with the proper administration of designated therapeutic dosages. An intake of very high dosages of the drug (5 g) or an extract (12 g) leads to vomiting, headache, dizziness, limb
pain, and lowered blood pressure. Hes sanitizing or whitewashing if not ignoring the mild side effects reported in two of the five German studies cited above. He refers to the gastric side effects as adverse effects as distinct from side effects. I detect a whitewash of the cohosh, perhaps well deserved and scientifically accurate. Stay tuned.

Extracts (Black Cohosh):
- Estrogenic and hypotensive effects reported (AHP). Resin hypotensive (1 mg/kg). Triterpenes hypocholesterolemic. Formononetin binds to estrogen receptor sites, induing an estrogen-like activity in the body (SKY). Alcoholic extracts decrease luteinizing hormone secretions in menopausal women (SKY). Cimicifugin antispasmodic and sedative (PED) but rapidly converted to an inactive compound when the fresh root is bruised or cut. Formononetin may act as estradiol antagonist (binding to the receptor but not producing an effect) rather than an agonist (binding to and activating the receptor), hence not affecting LH secretion (MAB). Studies of 13 American populations of black cohosh refute the presence of formononetin.
