Similar species (if any): Eupatorium perfoliatum can be distinghished from species with similar looking flowers by its perfoliate leaves on the central stem. The conspicuous surface texture on the leaves can aid in an ID. Brickellia eupatorioides (False Boneset) has similar looking flowers, but the alternate leaves are very different from the perfoliate leaves of Eupatorium perfoliatum. Eutrochium species in the state could also be differentiated by the difference in leaves and their arrangement of the stem. Eupatorium altissimum (Tall Boneset) can also be distinguished from Eupatorium perfoliatum by the appearance of the leaves. Ethnobotany: The Menominee employed this plant to treat fevers (Smith, p. 30, 1923). The Meskwaki employed the roots of this plant long ago as a cure for snake bite (Smith, p. 214, 1928). The Chippewa utilized this species to treat rattlesnake bite and also used it in the treament of rheumatism and irregularities of menses (Gilmore, pp. 142-143, 1933).
