A complex of an anionic polysaccharide with silver. The complex is preferably a salt formed between the polysaccharide and Ag<+> and the anionic polysaccharide is preferably a polycarboxlate. The anionic polysaccharide may be selected from alginates, hyaluronates, pectins, carageenans, xanthan gums, sulfated dextrans, cellulose derivatives, oxidised celluloses and mixtures thereof. Also claimed is a wound dressing, such as a sponge sheet, a woven or non-woven fabric, or a gel sheet, comprising a complex of an anionic polysaccharide with silver for treating ulcers. The wound dressing may further comprise collagen and preferably also comprises oxidised regenerated cellulose. Also claimed is the use of the aforementioned complex for the preparation of a medicament for the treatment of wounds and a method of making the complex comprising the step of treating an anionic polysaccharide with a solution of a silver salt. |
