Overview
Boneset (Eupatorium perfoliatum) is a bitter-tasting, upright perennial that can reach about 5 ft (1.5 m). It has lance-shaped leaves and clusters of small white or sometimes purple florets. Renowned in traditional American herbal medicine for colds, fevers, and influenza - especially when body aches are severe - it is believed to stimulate white blood cell activity and encourage sweating, thereby reducing fever and supporting the immune response.
