Protopanaxadiol (PPD) is an organic compound that is an aglycone of ginsenosides, a group of steroid glycosides. It is a dammarane-type tetracyclic terpene sapogenin found in ginseng (Panax ginseng) and in notoginseng (Panax pseudoginseng).[1][2]

The health effect of protopanaxadiol inside the human body is still unclear. One study suggests it has rapid, non-genomic effects on endothelial cells, binding to the glucocorticoid and oestrogen beta receptors. The study also showed an increase in intracellular calcium ion concentration.[3]
