A carminative, also known as carminativum (pluralcarminativa), is an herb or preparation that either prevents formation of gas in the gastrointestinal tract or facilitates the expulsion of said gas, thereby combatting flatulence.
The English author Aldous Huxley includes a long passage (chapter 20) about the word "carminative" in his novel Crome Yellow. The character Denis describes how he had loved the word since childhood, and had built up rich, elaborate associations with it until, with disappointment, he had discovered its true meaning.
