Black cohosh (Actaea racemosa, Cimicifuga racemosa) is a perennial herbaceous plant from the buttercup family, native to the eastern part of North America.
Indigenous peoples, including the Cherokee and Delaware, traditionally used its rhizomes to treat women’s diseases, inflammatory processes, and as a general tonic.
In modern herbal medicine, black cohosh is valued primarily for its ability to alleviate symptoms of menopause and PMS.
History and Origin
Black cohosh has long been used in folk medicine as a women’s remedy. Decoctions and infusions of the roots were used for irregular menstruation, pain, hot flashes, and nervous tension.
The plant prefers shady, moist forests, forms dense colonies, and is found in the USA (Missouri, Kentucky, Tennessee) and Canada.
Due to overharvesting and habitat loss, it is listed in the Red Book in several regions.
Biological Properties and Active Substances

- flavonoids — possess antioxidant activity, protect cells from oxidative stress;
- alkaloids — affect the central nervous system, help with pain syndromes;

Thanks to this complex, black cohosh exhibits anti-inflammatory, analgesic, calming, and mild hormone-regulating effects.

Standardized extracts of the rhizomes are more commonly used in herbal preparations.

In folk medicine, decoctions and infusions are used, sometimes in combination with lemon balm or mint.
