Blood clotting spray is an aerosol product which may be applied to minor wounds to coagulate bodily fluids and seal the wound. It may also provide a pain-killing effect.
It was developed in the mid 1990s and is made up of the same components as a natural scab. The spray coats small cuts as a quick-heal. The formed clot is clean and clear.
The main components are benzethonium chloride and Lidocaine. Average pricing on a can ranges from 10-20 USD.
