Yellow gentian is the commonly used European species, though all species are considered to have similar properties and are used interchangeably. Blue flowered species predominate in the Northern Hemisphere, red flowers in the Andes and white flowers in New Zealand. The yellow species (Gentiana lutea) is most often sited in western herbal texts, but all species have similar properties. The highly toxic white hellebore (Veratrum album) plant has been mistaken for white gentian. Proper plant identification matters, if in doubt, use the more commonly used yellow varietal (Gentiana lutea).

The plant is famous for its bitterness which is not diminished by drying or dilution. Many beverages are made with gentian root. The herb is used in aperitifs, liqueurs, digestifs and tonics. Bitter digestive drinks commonly use gentian root as an ingredient. The French liqueur Suze, the Italian liqueur Aperol, the German digestif Underberg, and the bitter drink known as Angostura Bitters, all contain gentian root.

The genus name Gentiana is attributed to the King of Illyrain (180-167 B.C.) who is said to have discovered the plant’s tonic properties.

Dioscorides, one of the first reliable western herbalists to document herbal functions, recommended gentian for digestive issues and as a poultice to treat inflamed eyes.

The German “father of natural healing,” Sebastian Kneipp praised gentian as an herb to support stomach secretions and strengthen nerves. He recommended if you only have a small garden then you ought to be sure to grow sage, wormwood and gentian.

The Chinese name, Long Dan Cao (G. scabra), translates as “Dragon’s Gall” and is a reference to the plant’s extremely bitter taste. A Chinese Materia Medica dating from ca. 500 A.D. categorized gentian as being an “upper class” herb due to its general efficacy and ability, if taken over time, to promote health and longevity.

Studies in China indicate that small doses of Long Dan Cao (G. scabra) have an affect on the secretion of gastric juices.

In China, Long Dan Cao (G. scabra) and Qin Cao (G. macrophylla) are differentiated from one another as follows: Long Dan Cao (G. scabra) is considered stronger in its heat clearing actions and Qin Jiao (G. macrophylla) is considered stronger in clearing Wind-Damp conditions. Long Dan Cao (G. scabra) is better at treating deficiency Heat syndromes involving Liver and Gall Bladder Fire channels. Qin Jaio (G. macrophylla), is better at treating excess Liver syndromes with Fire flaring upwards to the head and face (red eyes, headaches etc.) Both are extremely bitter herbs and have the same properties as all bitter herbs the world over.

The most common disease that Qin Jiao (G. macrophylla) was used to treat before antibiotics was likely tuberculosis. The disease causes extreme deficiency, night sweats, intermittent fever and overall weakness and fatigue.

In the Middle Ages, the plant’s were used as an antidote for poisons and in the 18th century gentian wine was served as an aperitif before dinner.

Only a few species are able to be cultivated, most occur in their wild habitats. They are popularly grown in rock gardens.

The roots have a strong, disagreeable odor and can taste slightly sweet at first, and then, they quickly become extremely bitter.

Gentian roots and leaves have been used in traditional Austrian medicine to treat skin, liver, flu, rheumatism and more.
