Centaury (Centaurium erythraea) is a premier bitter tonic containing extremely bitter secoiridoid glycosides (like gentiopicroside and centapicrin). When centaury is tasted, its extreme bitterness triggers a rapid, parasympathetic nerve reflex in the mouth that stimulates salivary glands, stomach acid, pepsin, and bile secretions. This effectively jumpstarts a sluggish digestive system, stimulates a poor appetite, and relieves indigestion.
