Discussion
Maine and Vermont specimens probably were planted originally.
Several varieties (A. Gray et al. 1878-1897, vol. 1(1,1), pp. 53-55) or forms (M. L. Fernald 1950) have been named. Specimens with extremely dissected leaves from Connecticut to Delaware and Virginia have been called Cimicifuga racemosa var. dissecta A. Gray, or C. racemosa forma dissecta (A. Gray) Fernald. Of the approximately 2500 specimens of C. racemosa examined, only twelve represent var. dissecta, and only two of those have flowers or fruits. Because of the limited knowledge concerning the dissected-leaf form, and because plants similar to those referred to by Gray and Fernald have not been collected in this century, the form is of uncertain taxonomic significance. Further study is needed.
Native Americans used infusions of plants of Cimicifuga racemosa medicinally to stimulate menstruation, to treat rheumatic pains, coughs and colds, constipation, and kidney trouble, to make babies sleep, and to promote milk flow in women (D. E. Moerman 1986).
