The acupuncture point CV12 (Zhongwan) was needled in this study and the impact on blood sugar was evaluated ⁽¹⁾ . Placebo was also used by needling in a separate location. The needle was retained for 30 minutes. The results showed a significant reduction in random blood glucose levels in the acupuncture group compared to baseline. No such change was observed in the placebo group. The authors conclude that 30 minutes of needling CV12 may be useful in reducing blood sugar levels in type 2 diabetics.
