The "wild sage" of the Western plains.
Preparation.—It is used in infusion, a tincture is prepared, and it yields an oil by distillation.
Therapeutic Action.—A correspondent in the West writes: "The herb is used as a fomentation by our best physicians. By the people in infusion for fever, rheumatism, diphtheria, and putrid sore throat. The oil is used as a liniment, mixed with olive oil, in deep-seated erysipelas, with the best results. Bruises, sprains, and swellings, are treated in the following manner: the part being bathed with the oil, the hot herbs are bound on the part and covered with oiled silk to prevent evaporation. The results are most gratifying."
