Gentiana /ˌdʒɛntʃiˈeɪnə/[1] is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Gentianeae, and the monophyletic subtribe Gentianinae. With about 400 species it is considered a large genus. They are notable for their mostly large, trumpet-shaped flowers, which are often of an intense blue.[2]
The genus name is a tribute to Gentius, an Illyrian king who may have been the discoverer of tonic properties in gentians.[3]
This is a cosmopolitan genus, occurring in alpine habitats in temperate regions of Asia, Europe and the Americas. Some species also occur in northwestern Africa, eastern Australia, and New Zealand. They are annual, biennial, and perennial plants. Some are evergreen, others are not.
Many gentians are difficult to grow outside their wild habitat, but several species are available in cultivation. Gentians are fully hardy and can grow in full sun or partial shade. They grow in well-drained, neutral to acid soils rich in humus. They are popular in rock gardens.
Many beverages are made with gentian root.[4] It is used to produce gentian, a distilled beverage produced in the Alps. Some species are harvested for the manufacture of apéritifs, liqueurs, and tonics.
Gentian root is a common beverage flavouring for bitters. The soft drink Moxie contains gentian root.[5] The French liqueur Suze is made with gentian. Americano apéritifs contain gentian root for bitter flavoring.[6] It is an ingredient in the Italian liqueur Aperol. It is also used as the main flavor in the German after-dinner digestif called Underberg, and the main ingredient in Angostura bitters.
Gentian is used in herbal medicine to treat digestive problems, fever, hypertension, muscle spasms, parasitic worms, wounds, cancer, sinusitis, and malaria.[7] Gentian has also been listed as one of the 38 plants that are used to prepare Bach flower remedies
Gentiana punctata leaves and roots have been used in the traditional Austrian medicine internally and externally as liqueur or tea for treatment of disorders of the gastrointestinal tract, skin, locomotor system, liver and bile, for paediatric problems, fever, flu, rheumatism and gout.[8]
Gentians have oppositely arranged leaves, sometimes in a basal rosette. The trumpet-shaped flowers are usually deep blue or azure, but can be white, cream, yellow, or red. Many species are polymorphic with respect to flower color, bearing flowers of different colors. Blue-flowered species predominate in the Northern Hemisphere, with red-flowered species dominant in the Andes, where bird pollination is probably more often favored by natural selection. White-flowered species are scattered throughout the range of the genus but dominate in New Zealand. Most flowers are pentamerous, with 5 lobes in the corolla and 5 sepals. A few species have 4 to 7 flower parts. The corolla has folds called plicae between the lobes. The style is short or absent. The ovary is mostly sessile and has nectary glands.
