Protopanaxadiol
Protopanaxadiol is an organic compound characterizing a group of ginsenosides. It is a dammarane-type tetracyclic terpene sapogenin found in ginseng and in notoginseng.
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.
