They share the characteristics of regulating the urinary system, (UB-32 Ciliao and to a lesser extent UB-33 Zhongliao are the strongest), the Intestines (UB-34 Xialiao has the widest effect), gynecological disorders (UB-34 Xialiao has the strongest effect) and moving Qi and Blood in the channels and collaterals of the local area and the lower limbs (UB-32 Ciliao and UB-33 Zhongliao are the strongest).
  • All four of these points tonify the Kidneys.
  • They are specific for genital disorders.
  • They tonify the whole body.
  • These points can induce labor.
  • UB-32 Ciliao is the most important of the four points and the one that is the most tonifying of the Kidneys and Jing.
