An eastern North American perennial herb. A substance obtained from the root of the plant has been used in some cultures to treat a number of medical problems.

Definition 2

A triterpene-containing herb isolated from the roots and rhizomes of the plant Cimicifuga racemosa (also known as Actaea racemosa).

In vitro, this preparation has been shown to induce cell cycle arrest and caspase-dependent apoptosis of estrogen-sensitive breast cancer cells. (NCI Thesaurus)
