Gentiana lutea – root

Famously used as a bitter digestive tonic, gentian stimulates the appetite and digestion by promoting the production of saliva, gastric juices and bile.

These actions make it useful for a sluggish digestive system as seen in dyspepsia and flatulence. It is a component of alcoholic aperitifs which are served before meals to stimulate appetite, as well as digestifs, which are served after meals to aid digestion.


Primary: bitter tonic, sialogogue, cholagogue.

  • Relief of mild diarrhoea.
  • Caution in peptic ulcer and hyperacidity.
