Spearmint leaves come from the spearmint plant, a member of the mint family. They are bright green, with a smooth texture and a distinctive, refreshing aroma. Spearmint is commonly used in cooking, beverages, and herbal teas due to its sweet flavor, which is milder than that of peppermint. These leaves are rich in essential oils, particularly carvone, which gives them their characteristic scent and taste. In addition to culinary uses, spearmint leaves have been traditionally used for their potential health benefits, including aiding digestion and providing relief from headaches.
