Commentary for Zhongji REN-3

Zhongji REN-3 is an important point for any genitourinary issues. 

First all, it is frequently used to clear Dampness, particularly Damp-Heat, from the Lower Burner. Therefore it can treat symptoms like pain and burning urination genital itching or pain, excessive vaginal discharge or Shan disorders (Hernial and Genitourinary disorder). When combining with other distal points (Sanyingjiao SP-6, Yinlingquan SP-9 or Ligou LIV-5 depending on the actual cases), it also treats fever or bloody urine. 

Secondly, REN-3 is a major point to benefit the Bladder and its Qi transformation function, especially for acute and Excess/Full cases. Thus Reducing Needling method is used more often. On the other hand, Tonifying Needling method can also be applied to strengthen the Bladder, but less often. The typical symptoms are frequent or retention of urination as well as painful and dark urine. 

It is effective in regulating menstruation as well, by benefiting the Uterus and Directing Vessel. It can be used to treat painful periods, retention of placenta or abdominal masses which are caused by Blood Stagnation in the Uterus. 

Finally REN-3 strengthens the Kidneys and nourishes its Essences, so as to tonify the original Qi. Therefore, it can treat lower back pain, dizziness, tinnitus and weak knees.
