Hydrogels based on low-methoxyl amidated citrus pectin and flaxseed gum formulated with tripeptide glycyl-l-histidyl-l-lysine improve the healing of experimental cutting wounds in rats.

Researchers evaluated hydrogels made from low-methoxyl amidated citrus pectin and flaxseed gum combined with the tripeptide GHK (glycyl-L-histidyl-L-lysine) for wound healing in a rat cutting wound model. The hydrogel formulation demonstrated improved healing outcomes in the experimental wounds compared to control groups. This is **animal model evidence** with no direct human clinical applicability at this stage.
