Some experimental study on He-Ne laser acupuncture is analysed; 1. penetration test,, a He-Ne laser can penetrate 1.8 cm of skin into the body; 2.temperature rising test, after laser irradiation of the points, temperatures in the correlative points arise; 3. a He-Ne laser can excite the bropagated sensation along the channels (PSC); 4. the electric conductivity of the points has regular change due to laser irradiation.The above experiments indicate that the mechanism of laser acupuncture induced reactions through channels and points has been verified at a certain degree.
