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.
AdvertisementThe 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.
