Gentian is the intensely bitter root of a mountain wildflower in the genus Gentiana, used as a flavoring agent rather than as a food on its own. The bitterness comes from a compound called gentiopicrin and is used to season bitters, aperitifs, gin, and herbal liqueurs, where it balances sweetness and adds complexity. The root is typically dried, powdered, or made into an extract before use; it also flavors traditional Alpine spirits, such as the herbal liqueur genepi, and contributes to the character of some Swiss and Italian cheeses. Gentian has a long history in traditional herbal medicine, though in the kitchen its role today is mainly as a bittering agent in drinks.
