Hemostatic: Styplon Vet is a styptic that controls bleeding by converting prothrombin (a blood clotting protein) to thrombin (protein which plays a central role in provoking the assembly of other proteins to form the blood clot). Stylon Vet stimulates hemopoietic organs, which increase the production of platelets, stabilize capillary endothelium (cells that line the interior surface of blood vessels) and maintain vascular integrity.
