Botanical Name : Gentiana lutea
Species: G. lutea
Common Name :Great yellow gentian
Other names: Yellow gentian, bitter root, bitterwort, centiyane, genciana and the Devil’ taint
Habitat: The Yellow Gentian is a native of the Alpine and sub-alpine pastures of central and southern Europe, frequent in the mountains of Spain and Portugal, the Pyrenees, Sardinia and Corsica, the Apennines, the Mountains of Auvergne, the Jura, the lower slopes of the Vosges, the Black Forest and throughout the chain of the Alps as far as Bosnia and the Balkan States. It does not reach the northern countries of the Continent, nor the British Isles. At an elevation of from 3,000 to 4,500 feet, it is a characteristic species of many parts of France and Switzerland, where, even when not in flower, the numerous barren shoots form conspicuous objects: the leaves are at first sight very similar to Veratrum album, the White Hellebore, which is its frequent companion. Out of Europe, the plant occurs in the mountains of Lydia. In some parts it occupies large tracts of country, being untouched by any kind of cattle.
Gentiana lutea is a herbaceous perennial plant, growing to 1–2 m tall, with broad lanceolate to elliptic leaves 10–30 cm long and 4–12 cm 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.
The root is long and thick, generally about a foot long and an inch in diameter, but sometimes even a yard or more long and 2 inches in diameter, of a yellowish-brown colour and a very bitter taste. The stem grows 3 or 4 feet high or more, with a pair of leaves opposite to one another, at each joint. The lowest leaves have short foot-stalks, but the upper ones are stalkless, their bases almost embracing the stem. They are yellowish-green in colour, oblong in shape and pointed, rather stiff, with five prominent veins on the underside, and diminish gradually in size as they grow up the stem. The large flowers are in whorls in the axils of the uppermost few pairs of leaves, forming big orange-yellow clusters. The corollas are wheel-shaped, usually five-cleft, 2 inches across, sometimes marked with rows of small brown spots, giving a red tinge to the otherwise deep yellow. Seeds in abundance are produced by strong plants, and stock is easily raised from them.
For the successful cultivation of G. lutea, a strong, loamy soil is most suitable, the deeper the better, as the stout roots descend a long way down into the soil. Plenty of moisture is also desirable and a position where there is shelter from cold winds and exposure to sunshine. Old plants have large crowns, which may be divided for the purpose of propagation, but growing it on a large scale, seeds would be the best method. They could be sown in a frame, or in a nursery bed in a sheltered part of the garden and the young seedlings transplanted. They take about three years to grow to flowering size. It is, however, likely that the roots are richest in medicinal properties before the plants have flowered. A big clump of G. lutea is worthy of a conspicuous position in any large flower garden, quite apart from its medicinal value.
Medicinal Uses: Gentiana is a plant extract made from gentians, which are a group of perennial plants belonging to the Gentianaceae family. There are about 180 species of gentians worldwide. They have a long history of use in healing both in Asian and Western herbalism . In the West, the common gentian used in healing is Gentiana lutea, or yellow gentian. In China, two different gentians are used in healing, Gentiana macrophylla, known in Chinese as qin jiao ; and Gentiana scabra, known in Chinese as long dan cao.
Part Used: The rhizome and roots collec
ted in autumn and dried. When fresh, they are yellowish-white externally, but gradually become darker by slow drying. Slow drying is employed to prevent deterioration in colour and to improve the aroma. Occasionally the roots are longitudinally sliced and quickly dried, the drug being then pale in colour and unusually bitter in taste, but this variety is not official.
Gentian is used in herbal medicine to treat digestive problems, fever, hypertension, muscle spasms, parasitic worms, wounds, cancer, sinusitis, and malaria, although studies have shown no efficacy beyond that of a placebo.
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
Constituents: The dried Gentian root of commerce contains Gentiin and Gentiamarin, bitter glucosides, together with Gentianic acid (gentisin), the latter being physiologically inactive. Gentiopicrin, another bitter glucoside, a pale yellow crystalline substance, occurs in the fresh root, and may be isolated from it by treatment with boiling alcohol. The saccharine constituents of Gentian are dextrose, laevulose, sucrose and gentianose, a crystallizable, fermentable sugar. It is free from starch and yields from 3 to 4 per cent ash.
Gentian is one of the most useful of our bitter vegetable tonics. It is specially useful in states of exhaustion from chronic disease and in all cases of general debility, weakness of the digestive organs and want of appetite. It is one of the best strengtheners of the human system, and is an excellent tonic to combine with a purgative to prevent its debilitating effects. Many dyspeptic complaints are more effectually relieved by Gentian bitters than by Peruvian Bark. It is of extreme value in jaundice and is prescribed extensively.
Besides being unrivalled as a stomachic tonic, Gentian possesses febrifuge, emmenagogue, anthelmintic and antiseptic properties, and is also useful in hysteria, female weakness, etc. Gentian with equal parts of Tormentil or galls has been used with success for curing intermittent fever.
As a simple bitter, Gentian is considered more palatable combined with an aromatic, and for this purpose orange peel is frequently used. A tincture made with 2 OZ. of the root, 1 OZ. of dried orange peel, and 1/2 oz. bruised cardamom seeds in a quart of brandy is an excellent stomachic tonic, and is efficacious in restoring appetite and promoting digestion. A favourite form in which Gentian has been administered in country remedies is as an ingredient in the so-called Stockton bitters, in which Gentian and the root of Sweet Flag play the principal part.
