How it works

Tanshinones and salvianolic acids from danshen have shown vasodilatory and microvascular effects in laboratory and traditional contexts. Magnesium tanshinoate B is proposed to enhance nitric oxide signaling and blood flow. Danshen has long traditional use for cardiovascular complaints.
