Common Boneset

Eupatorium perfoliatum

''Eupatorium perfoliatum'', known as common boneset or just boneset, is a North American perennial plant in the aster family. It is a common native to the Eastern United States and Canada, widespread from Nova Scotia to Florida, west as far as Texas, Nebraska, the Dakotas, and Manitoba. It is also called agueweed, feverwort, or sweating-plant. It was introduced to American colonists by natives who used the plant for breaking fevers by means of heavy sweating. It is nearly always found in low, wet areas.
