Black Cohosh

Cimicifuga Racemosa

Native Americans valued Black Cohosh for its benefits in many conditions ranging from gynaecological problems to rattlesnake bites. Some American physicians used Black Cohosh for problems such as fever, menstrual cramps, arthritis and insomnia. Recent scientific investigation has upheld the use of black cohosh in treating both dysmenorrhoea and menopausal symptoms.


The average recommended dose is 200-250mg three times per day. May be taken long term at normal dosages although the Commission E recommends not more than 6 months.

Potential applications

Research suggests that Black Cohosh is a suitable remedy for the treatment of menopausal and PMS symptoms (e.g. ovarian pain). May also be suitable for polycystic ovarian syndrome, infertility and other conditions where LH is elevated. There is relevant research pointing to its benefits in hypertension, reducing high cholesterol, reducing mucus production i.e. chest infections, expectorant action. Benefits are also noted for depression, headaches, and cardiovascular and circulatory disorders.

Known contraindications

Should not be used by pregnant or lactating women. Very large amounts (several grams) of Black Cohosh may cause abdominal pain, nausea, headaches and dizziness.


Women taking oestrogen therapy (HRT) should consult a knowledgeable nutritionist/herbalist before commencing to use Black Cohosh. It would appear appropriate to use Black Cohosh and tamoxifen concurrently although professional guidance by a physician is recommended.
