The plant Eupatorium perfoliatum.—U. S.
Preparation.—Tincture of Eupatorium.
Dose.—From the fraction of a drop to half a drachm.
Therapeutic Action.—Eupatorium is tonic, diaphoretic, emetic, aperient, and expectorant. It may be so administered as to fulfill a variety of important indications in the treatment of disease, according to the dose and mode of administration; for this reason it is somewhat difficult to say which of its properties is most prominent, and under what class of agents it should be described. Believing it to be more frequently used as a tonic, we shall attach it to that class of agents.
Eupatorium is a mild, simple, valuable bitter, and may be employed in all cases where the simple tonics are indicated. Administered alone, or associated with other tonics, aromatics, or stimulants, it answers a valuable purpose in the convalescent forms of acute diseases. The same may be said of it in dyspepsia, and almost all chronic diseases; as a general tonic, exhibited in the form of powder or small doses of a cold infusion, it answers an admirable purpose.'
