The single point specificity refers to the functional difference between single point and the non-acupuncture points, as well as other general acupuncture points. Namely, certain single point  have obvious curative effect to some illnesses or system diseases. At present most people believe that the single point functional specificity has both the universality and the relative specificity. The single point specificity first displays in the difference of the acupuncture effect between the acupuncture point and the non-acupuncture point. Clinic and experiment both proved that acupuncture on the single point has obvious functions, and acupuncture on the non-acupuncture point mostly has little or no function.
