The Leaves and Flowers.

(Eupatorium perfoliatum)

This plant is also called thoroughwort, Indian sage, feverwort, sweating plant, etc. It grows plentifully in almost every part of the United States, and may be found in meadows and in low, moist land. It grows from two to five feet high, branched at the top. The leaves are the broadest where they are connected with the stock, and taper off each way to a point. It remains in bloom from August to October. The flowers are of a dullish-white color, and are found on the top of the stem and branches. It should be collected when in bloom, and carefully dried.

Properties And Uses

The warm infusion of boneset, in large doses, operates as an emetic; in small doses it produces perspiration, and promotes all the secretions. The decoction, administered cold, is both laxative and tonic. It acts as a gentle laxative without irritating the bowels. Many families use the boneset alone in the cure of every form of disease, and are seldom disappointed in the result. There is no article in the Materia Medica more general in its application that boneset, either the infusion or decoction; it being a relaxant, sudorific, antiseptic, stimulant, diuretic, and tonic.


To produce vomiting, take two ounces steeped in a quart of water, but not boil; drink a cupful every fifteen minutes until it operates. For sweating, take the same in small doses, often repeated; for a tonic and laxative, drink a cupful of the decoction once in two hours.
