Wound healing is the process of repair that follows injury to the skin and other soft tissues.

Wounds may result from trauma or from a surgical incision. In addition, pressure ulcers (also known as decubitus ulcers or bed sores), a type of skin ulcer, might also be considered wounds. The capacity of a wound to heal depends in part on its depth, as well as on the overall health and nutritional status of the individual.

Following injury, an inflammatory response occurs and the cells below the dermis (the deepest skin layer) begin to increase collagen (connective tissue) production. Later, the epithelial tissue (the outer skin layer) is regenerated. Dietary modifications and nutritional and herbal supplements may improve the quality of wound healing by influencing these reparative processes or by limiting the damaging effects of inflammation.
