Gentiana lutea L.

Gentiana lutea (great yellow gentian) is a species of gentian native to the mountains of central and southern Europe. Other names include 'yellow gentian', 'bitter root', 'bitterwort', 'centiyane' and 'genciana'.

G. lutea is an herbaceous perennial plant, growing to 1–2 m (3.3–6.6 ft) tall, with broad lanceolate to elliptic leaves 10–30 cm (3.9–11.8 in) long and 4–12 cm (1.6–4.7 in) broad. The flowers are yellow, with the corolla separated nearly to the base into 5–7 narrow petals. It grows in grassy alpine and sub-alpine pastures, usually on calcareous soils.

G. lutea is remarkable for the intense bitterness of the root and every part of the herbage. Before the introduction of hops, gentian was used occasionally in brewing.

Gentian root has a long history of use as an herbal bitter and is an ingredient of many proprietary medicines. The parts used include the dried, underground parts of the plant and the fresh, above-ground parts. The root, which can be over 5 cm (2.0 in) thick and has few branches, is harvested in the autumn and dried for later use. Caution should be exercised as to its use because it is endangered, and the closely related Centaurium erythraea shares many of its constituents and actions.

The name is a tribute to Gentius, an Illyrian king who was thought to have found out that the herb had tonic properties.

In veterinary pharmacopeia in the 1860s, gentian root or gentian radix was considered useful as a tonic and stomachic.

Extracts of gentian root can be found in the American soft drink Moxie, and its unique flavor is attributed to that fact. It is also used in France to produce a Limousin specialty liqueur and aperitif, with plants gathered from the Auvergne area.
