Peppermint leaves in water may have the effect of transmitting rashes, detoxifying the liver, and evacuating wind-heat, but the infusion may not be able to completely precipitate the active ingredients of peppermint, plus it is only a single flavor of the drug, so the efficacy is limited. Mentha piperita leaves are the dried above-ground parts of the plant Mentha piperita, family Labiatae. It has the effects of dispersing wind-heat, clearing the head and eyes, inducing diaphoresis, penetrating rashes, and clearing the liver and promoting the flow of qi. It is used in treating wind-heat colds, the first signs of wind-warmth, headache, eye redness, paralysis of the throat (redness, swelling and pain in the pharynx, or dryness, foreign body sensation, or itchy throat with discomfort and difficulty in swallowing), mouth sores, rubella, measles, and distension of the chest and ribs (chest and rib cage area). Mentha piperita is recommended to be used under the guidance of a Chinese medicine practitioner for evidence-based guidance, unauthorized use may result in adverse consequences.
