It has a significant dilating effect on cerebrovascular and cardiovascular systems, especially on the vertebral artery system, significantly increasing the blood flow to the heart, brain and peripheral circulation, improving blood circulation, and lowering systemic blood pressure; increasing blood flow to the cochlea and anterior base, thereby eliminating inner ear vertigo, tinnitus and ear closure; increasing capillary permeability, promoting the absorption of extracellular fluid, and eliminating lymphatic edema; counteracting the vasoconstrictive effect of catecholamines and lowering arterial pressure, inhibiting plasma coagulation and ADP-induced platelet aggregation, and prolonging the time of thrombosis in vitro in rats; and having a slight diuretic effect.
