CoTCCC-recommended hemostatic gauze dressings, including Combat Gauze, ChitoGauze, and Celox Gauze, are safe and contain active ingredients that assist with blood-clotting at the site of active bleeding. 

To effectively form a clot and stop bleeding, hemostatic gauze must be packed into the wound to maximize contact at the active source of bleeding with direct pressure applied over the wound for at least 3 minutes.

Note: Although both ChitoGauze and Celox contain Chitosin, which is a shellfish derivative, they will not cause an allergic reaction in casualties with a shellfish allergy.
