Blue cohosh is also known as Caulophyllum thalictroides, blue ginseng, papoose root, yellow ginseng, blueberry root, and beech drops. Blue cohosh has been used to stimulate menstrual flow, to induce labor, and for rheumatism, cramps, and epilepsy. Blue cohosh is a woodland plant in the same family as barberry, goldenseal, and Oregon grape root, native to the eastern United States and Canada. The word cohosh is from Algonquian and means rough, which refers to the root. The stem is bluish, which is where the rest of the name comes from.
