Stop bleeding in seconds with BioLife WoundSeal. This specialized powder is composed of a non-toxic hydrophilic polymer and potassium ferrate. When applied to a bleeding wound, it reacts with the blood's moisture to create an instant, protective "scab" or seal. This seal stops bleeding immediately, protects the wound from dirt and bacteria, and stays in place until the wound heals. It is especially effective for people who have difficulty stopping bleeding due to the use of blood thinners or for those with minor cuts, abrasions, and skin tears.
