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

Just what protopanaxadiol's metabolites do 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 of intracellular calcium ion concentration.[3]
