The ground up rhizomes (root) of this plant are still used by herbalists to help heal fresh wounds and bruises.

This is a larger plant with larger, coarser leaves than the more common Small Solomon's-Seal. It ranges from 2 to 8 feet high, but is usually over 4 feet high. It grows in rich woods, riverbanks, and thickets from southern Manitoba into New England then south into the upper South. Flowers and fruit are in clusters of 2 to 10. It makes a nice informal perennial in shady to partly shady places. It spreads by thick, white underground rhizomes. It is sold by some native plant nurseries.
