Action and Therapy.—Sage is a feeble tonic, astringent, and diaphoretic. The infusion provides a good gargle for ulcerated and inflamed throat and for relaxation of the uvula. Taken warm, it produces free sweating, while cold sage tea, by strengthening the cutaneous functions, restrains excessive sweating, and for this purpose is highly valued in phthisis and other wasting diseases. It acts best when the skin is soft and relaxed, the extremities cold, and the circulation weak. It is of considerable value in gastric debility with flatulence and has proved a good tonic in spermatorrhea. A good indication for salvia is urine of low specific gravity.
