Constituents Explained:


Twin leaf is a perennial plant; the horizontal, fleshy rootstock with matted fibrous roots produces a simple, naked scape, 12-18 inches tall. Emanating also from the rootstock, the large, smooth basal leaves, 3-6 inches long and 2-5 inches wide, are divided into 2 half-ovate leaflets. Blooming from April to May, a large, solitary, white, 8 petaled flower terminates the scape. The fruit is an obovate capsule. The plant is only 6-9 inches tall in flower, but is double that height in fruit

Traditional Use:

It has been used for the nevous system, and as a throat garle.1
