DOSE:
Of the Powder: 1–3 grams (1 scruple–1 dram)
In Decoction: 3–9 grams (TCM and West; 1–3 drams was used in the West)
NOTE:
While the Chinese Gentian is regarded as one of the Coldest medicines in the Materia Medica, the European Gentian was accounted warm in the West. Despite this, it was used to clear Bile and was regarded as an important medicine to 'open obstructions' of the Liver. Nevertheless the use of Gentian and Gentiana Long Dan Cao can be considered synonymous.
PREPARATIONS:
1. Dry-Fried Gentian:
Pieces of Gentian root are dry-fried in a wok until scorched but not charred, then sprayed with water to stop the burning. The pieces are then dried and kept for use. This preparation is less cooling and the bitter nature is reduced. It is used to help Gentian enter the blood to cool the blood and stop bleeding. But is also less harsh on the Stomach and Spleen and so is better suited to those with digestive weakness.
2. Wine-fried Gentian:
Pieces of Gentian root are sprayed with alcohol (Rice spirit), then dried in an oven or by dry-frying in a wok. This preparation is less cold, and better to open obstructions. So for example, it is used for Liver heat conditions with Qi or Blood stagnation. It also has the effect of raising the effect of the herb to treat heat and inflammation in the head.
3. Fermented Gentian:
The Western Gentian was often fermented by being left in mounds. This makes it less Cold and Bitter and more gentle on the Stomach.
CORRECTIVES:
1. Licorice
2. Orange peel
3. Cardamon
4. Coriander seed
SUBSTITUTES:
1. Swertia
2. Centaury

History:

Pliny on Gentian:
|
From Culpeper
|
|
'Gentian was first discovered by Gentius, king of Blyria. It is a plant to be found everywhere, but that of Dlyria is the finest. It has a leaf like that of the ash, but equal in size to a lettuce-leaf : the stem is tender, about the thickness of the thumb, hollow and empty, and covered with leaves at regular intervals. This stem is sometimes three cubits in length, and the root is flexible, swarthy, and inodorous. It is found in the greatest abundance in humid localities at the foot of the Alps. The root and juice are the parts of it that are used: the root is possessed of certain warming properties, but it should never be taken by women in a state of pregnancy.'
|
"Gentian strengthens the stomach exceedingly, helps digestion, comforts the heart and preserves it against faintings and swoonings. The powder of the dry roots opens obstructions of the liver and restores appetite. The herb, steeped in wine, and the wine drank, refreshes such as be over-weary with travelling... is an excellent remedy for such as bruised by falls. It provokes urine and the terms exceedingly, therefore let it not be given to women with child... It helps agues of all sorts, and the yellow jaundice."
