Black cohosh

Description

Actaea racemosa, the black cohosh, black bugbane, black snakeroot, or fairy candle (syn. Cimicifuga racemosa), is a species of flowering plant of the family Ranunculaceae. It is native to eastern North America from the extreme south of Ontario to central Georgia, and west to Missouri and Arkansas. It grows in a variety of woodland habitats, and is often found in small woodland openings. The roots and rhizomes were used in traditional medicine by Native Americans. Its extracts are manufactured as herbal medicines or dietary supplements. Thereof, most of the dietary supplements containing black cohosh are not well-studied or recommended for safe and effective use in treating menopause symptoms or any disease. In contrast, some herbal medicinal products containing black cohosh (cimicifuga racemosa) extract hold a marketing authorization in several states of the European Union are well-studied and recommended for safe and effective use for the relief of menopausal symptoms (i.e. in the years around menopause) such as hot flushes and profuse sweating attacks. Such differentiation between the product types seems to be important. Black cohosh is a smooth (glabrous) herbaceous perennial plant that produces large, compound leaves from an underground rhizome, reaching a height of 25–60 cm (9.8–23.6 in). The basal leaves are up to 1 m (3 ft 3 in) long and broad, forming repeated sets of three leaflets (tripinnately compound) having a coarsely toothed (serrated) margin. The flowers are produced in late spring and early summer on a tall stem, 75–250 cm (30–98 in) tall, forming racemes up to 50 cm (20 in) long. The flowers have no petals or sepals, and consist of tight clusters of 55–110 white, 5–10 mm (0.20–0.39 in) long stamens surrounding a white stigma. The flowers have a distinctly sweet, fetid smell that attracts flies, gnats, and beetles. The fruit is a dry follicle 5–10 mm (0.20–0.39 in) long, with one carpel, containing several seeds.
