Thrombosis is another term for blood clotting. Clots can lead to heart attack and stroke. Researchers in China found that a water extract from Jiaogulan “could inhibit significantly the platelet aggregation induced by ADP and compound agonists (P < 0.05), accelerate obviously the disaggregation (P < 0.05) and inhibit effectively the experimental thrombosis (P < 0.05). The delayed effects of GP on KPTT, PT, TT, AT, RVV-RT, RVV-CT suggested that this drug could decrease the activity of multiple coagulation factors. And it showed that GP could accelerate the erythrocyte electrophoresis rate. This study revealed that GP is an antithrombotic agent affecting the links of thrombotic chain.”
