Eupatorium perfoliatum L.
Asteraceae (Aster Family)
USDA Symbol: EUPE3
Tiny, white flowers are arranged in fuzzy clusters top the 3-6 ft. stems of this perennial. Hairy plant with dense flat-topped clusters of many dull-white flowers. Paired leaves, united basally, are perforated by the erect stems.
As suggested by the Latin species name, the stem appears to be growing through the leaf. To early herb doctors, this indicated the plant would be useful in setting bones, so its leaves were wrapped with bandages around splints. The dried leaves have also been used to make a tonic, boneset tea, thought effective in treating colds, coughs, and constipation. Upland Boneset (E. sessilifolium) is somewhat similar, but its leaves are not fused at the base.
