Kräuterlikör [ˈkʀɔɪtɐlikøːɐ] (herbal liqueur or spiced liqueur, also called "half-bitters") is a type of liqueur that is flavored with herbs or spices and traditionally drunk neat as a digestif. The history of Kräuterlikör recipes dates back to medieval authors like Hildegard of Bingen. Mixtures of alcohol and bitter substances were used as medicine to increase bile and gastric acid secretion; however, the higher proportion of alcohol and sugar is not conducive to digestion. Nowadays, Kräuterlikör is also served as an ingredient of different cocktails and long drinks.
