From the Manufacturer:
Artichoke contains cynarin and scolymoside which have been shown to stimulate bile production and secretion. This supports the traditional use of Artichoke for creating support for sluggish livers and digestive irregularities. Cynarin creates support for lowering cholesterol and triglyceride levels in the blood. Artichokes also possess some diuretic activity, helping with kidney disease and protein in the urine.
