What is the principle of hemostatic powder?

The principle of hemostatic powder is to promote platelet aggregation and fibrin formation, thereby quickly coagulating wound bleeding and achieving the purpose of hemostasis. Specifically, hemostatic powder contains some substances that can stimulate platelet aggregation and vasoconstriction, such as hemagglutinin and collagen. These substances can quickly adhere to the wound surface, stimulate platelet aggregation and release platelet factors, thereby promoting platelet aggregation, thrombosis, and slowing bleeding.
