Acupuncture points can be identified as cutaneous neurogenic inflammatory spots.

Acupuncture, a traditional medical procedure practised for over 2000 years in Asia, stimulates specific but poorly defined sites called acupoints. To date, no unique anatomical acupoint structures have been found. However, noxious sensory signals from visceral organs produce hypersensitive spots on the skin (neurogenic spots), caused by cutaneous neurogenic inflammation, in the dermatome that overlaps with visceral afferent innervations.

An exploratory study of gold wire implantation at acupoints to accelerate ulnar fracture healing in rats.

By causing long-term stimulation, gold wire implantation at acupoints has been used empirically to prolong the effects of acupuncture. This study shows that subcutaneous gold wire implantation at acupoints has long-term effects on bone regeneration in the rat ulna bone defect model.

Skin on GV01 acupoint in colonic inflammatory states: tenderness and neurogenic inflammation.

GV01 is one of the most effective acupoints to treat diarrhea in humans and animals. The present study showed that skin on the GV01 acupoint reveals tenderness and neurogenic inflammation in colonic inflammatory states, but not in normal healthy states.
