Biological Activities
Compounds
Conditions
Polygonum arenarium acts as a potent agent in treating blood coagulation by influencing the coagulation cascade. In laboratory tests, the extracts of this plant were shown to significantly prolong both the prothrombin time (PT) and the activated partial thromboplastin time (aPTT). These results indicate that the plant exerts an additional effect on the common pathway of blood clotting. Consequently, Polygonum arenarium functions as a strong anticoagulant rather than a coagulant. This specific biological activity highlights its potential role in managing various cardiovascular diseases.
