Historical Background

Modern Evidence

Gentian has a tradition as a premier bitter digestive, stimulating saliva, gastric juice, and appetite (the 'bitter reflex'); preclinical and small studies support its digestive-stimulant activity. Clinical evidence is limited; it is not a treatment for indigestion, anorexia, or any disease, though it remains the classic pre-meal bitter cup.
