Hemostatic: Acting to arrest bleeding or hemorrhage
There are a number of commercial products out there on the market to stop profuse bleeding.
BioLife makes a powder product. Z-Medica makes a host of products all marketed under the name QwikClot. They range from dressings to products for more serious injuries, including trauma such as bullet wounds. LifeScience PLUS markets a product called BloodSTOP .
For some, these products may be out of the range economically, or you may not have access to them in time of need.
There is a way to make a similar product at home using things that you may already have.
