In recent times there has been growing interest in Wai Qi therapy and various methods of life energy treatment, and many clinical reports on these subjects are being published. Previously we conducted experiments to examine the scientific grounds for Wai Qi therapy. In this experiment we used animals to avoid suggested effects, and examined if Wai Qi can treat diabetes, a life-style related disease. We selected NOD (non-obese diabetic) mice for diabetes models. The mice were sorted into two groups. One received Wai Qi (Wai Qi group: Qi group) and the other did not (control group: Cy cont. group). Both groups were administered cyclophosphamide to the abdominal cavity. Results showed the incidence rate of diabetes was 88.5% with the Cy cont. group, but only 52.9% with Qi group. Thus, the incidence rate of diabetes of the Qi group was much lower than the Cy cont. group. On the basis of these results, we concluded that Wai Qi treatment for diabetes had a positive influence.
