Grape seed extract helps wound healing
According to researchers grape seeds help in wound healing. An extract of grape seed heals wounds by helping new blood vessels to grow and providing a high concentration of free radicals in the damaged area. Researchers at Ohio State University report on the first study of a natural extract on wound healing. They looked at how an extract of grape seed worked on both human skin cells and wounds in experimental animals.

The extract had a dynamic effect right from the beginning. Analysis showed that extract-treated skin showed signs of healing very aggressively and that newly formed tissue was dense with a strong structure. This was connected to increased levels of a protein called tenascin, which helps build new connective tissue.

The human skin cell experiments revealed how the extract increased levels of a growth factor for new blood vessels, whose regeneration is essential to wound healing. Another effect noted was how grape seed extract promoted free radical production in the wounded area - a process thought to speed up wound healing. This is in marked contrast to the effect of grapeseed extract taken by mouth, where it has an antioxidant effect.
