Native to the moist woodlands of North America, stoneroot is a perennial herb, growing to about three feet, having a square stem, oval leaves, and clusters of greenish-yellow flowers. The plant is strongly and unpleasantly aromatic and numbing in large amounts. The root is unearthed in autumn.
The rhizomes and dried roots have long been used to treat kidney and bladder problems and gastrointestinal disorders.
The Iroquois used the leaves in a poultice to relieve headaches while the Cherokee made a deoderant with the flowers.
