Zanshin, look for products like "Quik-Clot". These are available either as powders, or as impregnated bandages. The special ingredients cause rapid blood clotting, so blood loss is stopped and wounds sealed very rapidly.
A product of combat medicine, they've been on the civilian market for only a few years now but many pharmacies are starting to carry them. Much more effective than pouring granulated sugar on a wound--which is an alternative if you have nothing else. (The sugar promotes clotting by absorbing the fluid, it is reasonably sterile and water-washable.)
