Test on coagulation time,prothrombin time and platelet aggregation of mice and rats showed that all four species of Puhuang had effects on blood coagulation, in which Typha angustata Bory et Chaub. was the strongest followed by T. davidiana Hand. -Mazz., T. latifolia L,and T. angustifolia L. Their mechanism of coagulation were not the same,in which T. angustata Bory et Chaub. mainly acted on thrombogen,while T.davidiana Hand. -Mazz. mainly acted on platelet aggregation.
