Antihemorrhagic

An antihemorrhagic (British English: antihaemorrhagic) agent is a substance that promotes hemostasis (a process which stops bleeding).

They vary based on their mechanism of action, composition, ease of application, adherence to tissue, immunogenicity and cost.

These include antifibrinolytics, blood coagulation factors, fibrinogen, and vitamin K.[4] Topical hemostatic agents have been gaining popularity for use in emergency bleeding control, especially in military medicine.

Chitosan bonds with platelets and red blood cells to form a gel-like clot which seals a bleeding vessel.

[11] A styptic (also spelled stiptic) is a specific type of antihemorrhagic agent that works by contracting tissue to seal injured blood vessels.

Anhydrous aluminium sulfate is the main ingredient and acts as a vasoconstrictor in order to disable blood flow.
