The health effect of protopanaxadiol inside the human body is still unclear. One study suggests it has rapid, non-genomic effects on ]s, binding to the ] and ]. The study also showed an increase in intracellular calcium ion concentration.<ref name=LEUNG>{{cite journal|last=Leung|title=Protopanaxadiol and protopanaxatriol bind to glucocorticoid and oestrogen receptors in endothelial cells|journal=British Journal of Pharmacology|volume=156|issue=4|pages=626–637|display-authors=etal|doi=10.1111/j.1476-5381.2008.00066.x|pmid=19226254|pmc=2697710|year=2009}}</ref>
