The Mentha Piperita and M. Viridis, are decidedly diaphoretic. The Spearmint is to be preferred to the Peppermint, it being more energetic and certain in its action, and generally more acceptable to the stomach. The warm infusion should be taken liberally, the patient at the same time keeping quiet and warmly covered up in bed. In the incipient stages of the milder forms of fever, and other diseases, especially if accompanied with nausea and vomiting, or a morbidly irritable state of the stomach, a strong infusion of the mint will be found an appropriate and useful diaphoretic. In flatulence, colic, spasm of the stomach and bowels, etc., it is an excellent stimulant and carminative.
