Peppermint extract is an herbal extract of peppermint (Mentha × piperita) made from the essential oils of peppermint leaves. Peppermint is a hybrid of water mint and spearmint and was indigenous to Europe and the Middle East before it became common in other regions, such as North America and Asia.

Peppermint extract is commonly used in cooking, as a dietary supplement, as an herbal or alternative medicine, as a pest repellent, and a flavor or fragrance agent for cleaning products, cosmetics, mouthwash, chewing gum, and candies. Its active ingredient menthol activates the TRPM8 receptor in sensory neurons, resulting in a cold sensation when peppermint extract is consumed or used topically. There is insufficient evidence to conclude it is effective in treating any medical condition.
