This study aims to investigate the potential of Ehrtia laevis as coagulant. To do this the dried powder of this plant was extracted with acetone and isopropanol using soxhlet assembly. These solvents were evaporated to make aqueous extract which was subjected to coagulation (prothrombin test) using plasma and blood sample of healthy individual. The blood coagulation time of prothrombin test of both the plasma and blood samples was reduced as compared to the control.
