Eupatorium perfoliatum grows in wet soils in the eastern half of North America. Boneset is a perennial in the Asteraceae family and has been used for its beneficial properties by Native Americans for generations. Astringent and bitter, the dried aerial portions of boneset can be prepared as an extract, or as a warm or cold infusion. The tea is bitter. Boneset is a perennial daisy, growing 2 to 4 feet (60 to 120 cm) tall with a long, hairy stem topped with white flower heads of 10 to 20 blossoms from June to September.
