History. A very singular plant, similar in habit to Hypopythis, but with flowers like Andromeda. It had long been known to herbalists, yet was unknown to botanists, when discovered by Dr. James, in 1816, near Albany, and called Monotropa procera. In 1818, Nuttal established the genus, but mistook it for annual. It has as yet been found only in some sterile hilly sides, in the State of New York, in Genessee, near Albany, &c. It blossoms in July. It affords some varieties, 1. Flavicaulis. 2. Leucorhiza. 3. Elatior. 4. Pauciflora.

Properties. The root is the officinal part, resembling that of Monotropa; it has a vapid smell, and a mucilaginous astringent taste. It is employed by the Indians, the herbalists, and the Shakers of New Lebanon, as a valuable vermifuge, sudorific, anodyne, deobstruent and menagogue. They distinguish two kinds with purple and yellow stems, (called male and female) pretending that the first is best, but obviously wrongly. It is said to avail in all remittents, typhus, and nervous fevers; it produces a profuse perspiration, and often stops the fever in a few hours. It also relieves the night hectic fever, without debilitating the patients. It avails in pleurisies and erysipelatose fever. It is chiefly good in all low stages of fevers. Employed also in coughs, pains in the breast, and other diseases of the breast, made into a syrup. It is the base of some pectoral balsams. Also taken in decoction and in powder. My experiments on this root in diseases of the lungs, have not yet satisfied me of its utility; it appears useless in scrofulous consumption, but is beneficial in hectic fever and pains in the breast, much more so than Hepatica. This plant being rare, is sold high by the Shakers and herbalists. The Eupatorium, much more common, is probably also a preferable equivalent.
