Abstract
The present invention relates to the use of polyphosphate in crystalline form for treatment of wounds, especially bleeding wounds, wherein the anion of the polyphosphate has a (numerical) average of at least 4 phosphorus atoms per polyphosphate anion. The invention additionally relates to a composition suitable for treatment of wounds, especially bleeding wounds, comprising an inventive polyphosphate and a carrier material. The invention further provides a method suitable for production of the inventive composition, which comprises the introduction of the polyphosphate and optionally further haemostatic agents into the carrier material, or into a component or into a precursor of the carrier material.
