Boneset
Parts Used & Where Grown
Boneset belongs to the same botanical family as echinacea and daisy (Asteraceae). It grows primarily in North America. Boneset’s leaves and flowering tops are used medicinally.
How It Works
Boneset contains sesquiterpene lactones, such as euperfolin, euperfolitin, and eufoliatin, as well as polysaccharides and flavonoids. In a test tube study, a particular polysaccharide in boneset was found to stimulate immune cell function.1 This may partially explain its use to treat minor viral infections, such as colds and the flu. Boneset also triggers sweating by raising body temperature, potentially of benefit for colds and flu as well.2
