Peppermint extract is a herbal extract of peppermint (Mentha × piperita) made from the essential oil of peppermint leaves. Peppermint is a hybrid of water mint and spearmint.[1] The oil has been used for various purposes over centuries.[1]
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.[1][2] Its active ingredient menthol causes 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.[1][3]
