The tough fibrous roots were once used herbally for putative alimentary cures, and the name gentian derives from Gentius, king of ancient Illyria and alleged discoverer of the plant’s medicinal value. Gentiana lutea, the yellow gentian, is found in Europe and western Asia and is the source of a flavouring in liqueurs.
