Active constituents
Gentian contains bitter substances such as the glycosides gentiopicrin and amarogentin. The bitter taste of these can be detected even when diluted 50,000 times.2 Besides stimulating secretion of saliva in the mouth and hydrochloric acid in the stomach, gentiopicrin may protect the liver.3 Gentian is used to treat poor appetite and indigestion.4 An open study shows that gentian tincture inhibits the feeling of fullness after eating, suggesting it could improve poor appetite.5
How much is usually taken?
Tincture can be taken 20 minutes before each meal, for a total of 1/4–1/2 teaspoon (1–3 ml) daily. Alternatively, whole root, 1/2–3/4 teaspoon (2–4 grams) per day, can be used. Since capsules of the herb bypass the taste buds, they may not have the same effect as other dosage methods.
Are there any side effects or interactions?
Gentian should not be used by people suffering from excessive stomach acid, heartburn, peptic ulcer disease, or gastritis.6
At the time of writing, there were no well-known drug interactions with gentian.
