Point selections based on Zang Fu Bei Tong is a very practical needling method. Previous discussions have talked about the point selection from single channel, such as LI 11 on the large intestine channel to treat dizziness or vertigo related to the liver channel; and PC6 on the pericardium channel to treat stomach disorders. However, the point combinations from mutually connected organs are more important and very often applied to clinical practice. Examples are as below.

Shenguan and Wanshuanyi (22.08) and Wanshuaner (22.09) form a good combination to expel dampness and effectively treat lumbago. Those are the examples of the extraordinary connections of the spleen and small intestine.

Extraordinary connection of the heart and gallbladder: Fengshi (GB31) on the gallbladder channel and Shaofu (HT8) on the heart channel form a very good combination in expelling wind and stopping itchiness. Qiaoyin (GB44) and Shenmen (HT7) form an effective combination on treating insomnia and dreamful sleep. Those are the examples of the extraordinary connection of the heart and gallbladder.

5. Extraordinary connection of stomach and pericardium: The combination of Neiguan (PC6) and Zusanli (ST36) effectively treats stomach, heart, lung organ diseases, and many internal diseases, for example: digestive, circulation and respiratory system disorders. The effectiveness is through the extraordinary connection of the pericardium and stomach. This point combination is the most commonly used one in regulating heart, stomach and respiratory systems.

6. Extraordinary connection of liver and large intestine: The combination of Hegu (LI4) and Taichong (LV3) is called “four gates” which not only good at treating nasal disease (Song of Point Applications for Miscellaneous Disease), but also treats many major diseases. It is particularly strong at sedating and also is the most commonly used point pair.
