WoundSeal is a topical powder that stops bleeding by creating an instant scab (or seal) when combined with blood. The instant scab seals the wound, which stops the bleeding and creates a barrier over the wound. The seal lets nothing in and nothing out, helping to reduce the risk of infection. Beneath the seal, the body's healing mechanism begins; the scab falls off naturally as the wound heals. WoundSeal even works for people who bleed easily because it doesn't rely on the normal clotting factors in blood.
