Peppermint extract

[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.

If the food is not heated, the alcoholic properties of liqueurs may remain present in the finished product.
