Chitosan is deemed hypoallergenic and has properties which seem to rapidly clot blood, prompting the use in gauze dressings and bandages. Chitosan bandages used on battlefields in Iraq showed drastic increases in survival of wounded army personnel. As a nutritional supplement, chitosan is often marketed as a fat attractor.
