Commentary

Like any Connecting-Luo Channel, Zhizheng SI-7 can address various Channel Obstruction issues, such as elbows, neck or fingers along the Small Intestine Channel. It is particularly effective in treating elbow contracture. 

It connects to the Heart Channel, thus has influence over the Mind. In fact, it calms the Mind and is able to ease severe anxiety and mental restlessness. 

It expels Wind-Heat as well. The typical symptoms are aversion to cold, fever, febrile disease as well as fever with neck pain.

Finally Zhizheng SI-7 subdues Rebellious Qi, so that it can treat headache, dizziness or blurred vision. 

Classical Sources

Ling Shu (Spiritual Pivot), Chapter on Channels: "The Luo-Connecting vessel of Hand Tai Yang is called Zhizheng. It ascends 5 cun above the wrist and connects internally to Hand Shao Yin [Heart]. Its branch ascends to the elbow and connects to the shoulder bone. When excess, the joints become slack and the elbow is disabled. When deficient, warts grow, and small ones become scabies. Treat by taking the point where it separates."

Zhen Jiu Jia Yi Jing (Systematic Classic of Acupuncture): "Shivering with cold, alternating cold and heat, neck and nape swelling. Excess causes elbow contracture, head and neck pain, and manic behavior. Deficiency produces warts and small scabies. Zhizheng governs these."

Zhen Jiu Da Cheng (Great Compendium of Acupuncture): "Governs fright, fear, grief, worry, and manic disorders."

Yi Zong Jin Jian (Golden Mirror of Medicine): "Zhizheng mainly treats seven emotions causing qi stagnation and discomfort, unquenchable thirst from consumptive thirst disorder."

How to Locate

Apply the spreading hands technique to find the midpoint of the distance between Yanggu SI-5 and Xiaohai SI-8. First place both little fingers on SI-5 and SI-8 and span the hands evenly. The thumbs meets at the midpoint, from where measure 1 cun in a distal direction. Xiaohai SI-8 is located between the olecranon of the ulna and the medial epicondyle of the humerus.

Caution

Classical texts indicate this point is forbidden during the sixth month of pregnancy. The basilic vein (贵要静脉) runs in the subcutaneous tissue near this point - avoid piercing superficial veins. Use appropriate needle depth to avoid affecting the ulnar nerve which lies deeper in the region.
