any plant of the genus Cimicifuga,
tall north-temperate perennials of the family Ranunculaceae (buttercup
family). The white spirelike bloom has a rank odor that attracts flies, which pollinate the plant. Common in woodlands of E North America is C. racemosa,
black snakeroot, or black cohosh, whose root is used commercially as an herbal remedy for conditions associated with menopause
. (The most rigorous study of its use to treat menopause, however, reported in 2006 that it was not any more effective than a placebo.) Other plants are also called bugbane and snakeroot; most plants called cohosh belong to the related baneberry
genus. Bugbane is classified in the division Magnoliophyta
, class Magnoliopsida, order Ranunculales, family Ranunculaceae.
