A perennial 1 to 2 feet in height, with a single stem and thick rhizomes. Leaves are 3 to 6 inches across, and deeply cleft. Produces 3 to 5 loose, rosy-purple to white flowers, 1 inch across.
April to June.
Rich woods and meadows.
Leaves and rhizomes in spring, just before plant flowers, or in late summer.
The leaves have been used as a vulnerary. However, the roots and rhizomes, which contain much tannin, are very astringent, antiseptic, styptic, and diuretic; and they have been used to treat diarrhea. In Appalachia, a tea made from the whole plant is used to treat dysentery and sore throat.
