Abstract

A wound dressing makes use of a saccharide, such as Manuka honey, in combination with collagen in order to suppress the efficacy of matrix metalloproteinases enzymes (“MMPs”) present in chronic wounds. The mixture is applied to an absorbent surface that is designed to absorb the mixed saccharide only partially.

wherein the honey, the supplemental material and the collagen form a mixture in the wound contacting layer having a second viscosity that is greater than the first viscosity of the honey.

2. The dressing of claim 1 , wherein the supplemental material consists of cane sugar.

3. The dressing of claim 1 , wherein the supplemental material has antimicrobial properties.

4. The dressing of claim 3 , wherein the supplemental material consists of silver.
