Wintergreen refers to a group of plants, particularly those in the genus Gaultheria, which are known for their aromatic leaves and berries. The most common species, Gaultheria procumbens, is a low-growing evergreen shrub found in North America. Its leaves contain a compound called methyl salicylate, which gives wintergreen its characteristic minty scent and flavor. The oil extracted from wintergreen leaves is often used in products like pain relief ointments, toothpaste, and chewing gum. Additionally, wintergreen is sometimes used in herbal remedies for its potential anti-inflammatory properties. Its pleasant aroma makes it popular in aromatherapy and scented products.
