Boneset was a favorite medicine of the North American Indians, who called it by a name that is equivalent to ‘Ague-weed,’ and it has always been a popular remedy in the United States, probably no plant in American domestic practice having more extensive and frequent use; it is also in use to some extent in regular practice, being official in the United States Pharmacopceia, though it is not included in the British Pharmacopoeia.
—Constituents—All parts of the plant are active, but the herb only is official, the leaves and tops being gathered after flowering has commenced. They contain a volatile oil, some tannic acid, and Eupatorin, a bitter glucosidal principle, also resin, gum and sugar. The virtues of the plant are yielded both to water and alcohol.
—Description—Boneset is a perennial herb, with an erect stout, cylindrical hairy stem, 2 to 4 feet high, branched at the top. The leaves are large, opposite, united at the base, lance-shaped, 4 to 8 inches long (the lower ones being the largest), tapering to a sharp point, the edges finely toothed, the veins prominent, the blades rough above, downy and resinous and dotted beneath. The leaves serve to distinguish the species at the first glance – they may be considered either as perforated by the stem, perfoliate (hence the specific name), or as consisting of two opposite leaves joined at the base, the botanical term for which is connate. The flower-heads are terminal and numerous, large and slightly convex, with from ten to twenty white florets, having a bristly pappus, the hairs of which are arranged in a single row. The odor of the plant is slightly aromatic, the taste astringent and strongly bitter. This species shows considerable variety in size, hairiness, form of leaves and inflorescence. It flowers from July to September.
