Wound Healing with Acupuncture
Acupuncture is purported to facilitate wound healing by means of decreased sympathetic nervous system activation. The latter promotes local vasodilation (thus perfusion), decreases peri wound edema, and improves oxygen delivery to the affected tissues. Additionally, acupuncture (electroacupuncture in particular) has been shown to promote angiogenesis (new blood vessel formation) and increase the levels of wound healing accelerators such as fibroblast growth factors (FGF) and platelet-derived growth factors (PDGF).
