The Luo Connecting point of the Small Intestine channel — a bridge between the body's surface and the Heart. Zhizheng (SI-7) releases exterior Heat, calms an unsettled mind, and opens the channel from elbow to fingers.
Contraindications
Zhizheng (SI-7) is a safe point on the forearm with no special contraindications. Needle with clean technique and keep to the recommended depth.
Name & story
The name 支正 Zhizheng means "Branch of the Upright" — and the story is hidden in those words. The "Upright" channel is the Heart channel itself. The Small Intestine and the Heart are paired, interior and exterior partners, and at this point a branch leaves the Small Intestine channel and travels inward to join its Heart companion. Think of a side road quietly rejoining the main highway — that is Zhizheng, always connected to the Heart, always able to carry its message there. It is a humble point on the forearm, but its reach is longer than its location suggests.
Point family & character
Zhizheng (SI-7) belongs to the Small Intestine Meridian (SI). Its defining character is that it is the Luo Connecting point of the channel — the point from which the luo-connecting vessel branches off to link with the Heart Meridian (HE). As the Guide to the Classics of Acupuncture puts it, "the luo-connecting points are located between two channels... if they are punctured, symptoms of the interiorly-exteriorly related channels can be treated." This dual reach — outward to the surface and inward to the Heart — is what makes SI-7 distinctive.
Five-element dynamics
The Small Intestine belongs to the Fire element and to the taiyang layer — the most exterior of the six channels, the body's first wall against outside pathogenic factors. Because it stands at the outermost layer, Zhizheng (SI-7) is naturally equipped to release what has just arrived from outside: especially Wind-Heat and febrile conditions. At the same time, its luo branch runs directly to the Heart, the sovereign organ of Fire that houses the Shen. So this single point can work at both ends of the Fire element — clearing Heat at the surface while calming the spirit within.
Location
Find the transverse crease of the wrist on the ulnar (little-finger) side. Measure 5 Cun up the forearm along the line that connects SI-5 (at the wrist) and SI-8 (at the elbow). The point sits there on the back-inner edge of the forearm.
Anatomy & fascia
The point lies on the dorsal ulnar aspect of the forearm, on the line connecting Yanggu SI-5 and Xiaohai SI-8.
Needling
The needle is inserted perpendicularly.
Safe depth
0.5–1 Cun.
Moxa, cupping & Tui Na
Moxibustion can be applied to warm the channel in Cold conditions or when the channel is obstructed. Acupressure along the forearm and firm pressure on the point itself can help relieve local stiffness and pain in the elbow and fingers.
Functions
Expels Wind-Heat and releases the exterior. Calms the Shen and settles the mind. Removes obstructions from the channel and alleviates pain. Subdues rebellious Qi. As the Luo Connecting point, it treats conditions of both the Small Intestine Meridian (SI) and its paired Heart Meridian (HE). In clinical experience, it also helps resolve Phlegm swellings of the thyroid when combined with Pianli LI-6.
Indications
Febrile disease, aversion to cold and fever — especially when accompanied by neck pain and lumbar pain at onset. Headache, dizziness, blurred vision. Stiff neck, contracture or pain of the elbow, pain and weakness in the fingers and hand (inability to grip firmly or make a fist). Manic depression, fright, sadness, anxiety and mental restlessness. Warts (listed as the classic sign of deficiency of the luo-connecting vessel). Slackness of the joints and inability to move the elbow (excess of the luo-connecting vessel).
Mind & spirit (Shen)
Because Zhizheng (SI-7) sends its luo branch directly to the Heart — the home of the Shen — it has a genuine and pronounced effect on the mind. When fear, fright, sadness or anxious restlessness cloud the spirit, this point offers a direct route inward to calm things down. Old classical texts list manic-depression and fright among its clearest indications, and Maciocia notes that it is particularly useful in severe anxiety and mental restlessness through precisely this Heart connection. It does not nourish — it clears and settles, making it most suitable when the mind is disturbed by Heat or agitation rather than by emptiness.
Point combinations
With Yuji LU-10, Hegu LI-4, Shaohai HE-3, Quchi LI-11 and Wangu SI-4 — for manic raving, fear and fright (Thousand Ducat Formulas). With Sanjiaoshu BL-22 — for visual dizziness and headache (Supplementing Life). With Feiyang BL-58 — for visual dizziness (One Hundred Symptoms). With Pianli LI-6 — for Phlegm swellings of the thyroid.
Clinical spotlight
Zhizheng (SI-7) is one of those quietly powerful points that work on two levels at once. On the surface, it is a reliable point for releasing exterior Heat — useful early in a febrile illness, especially when neck and back pain are part of the picture, because the Small Intestine Meridian (SI) runs through both areas. Deeper in, its luo branch reaches the Heart and gives the point a genuine calming action on the Shen — classical texts group it with points for mania, fright and deep sadness. A third, more specific use noted by Maciocia: combined with Pianli LI-6, it can help resolve thyroid Phlegm swellings — an elegant application of the luo-connecting principle across paired channels.
The golden tip
If you are dealing with a stiff, achy forearm or elbow, or simply feel wound up and anxious, you can press or massage SI-7 yourself. Find the inner-back edge of your forearm on the little-finger side, roughly in the middle between wrist and elbow (5 Cun up from the wrist crease). Press firmly and hold for a minute or two, breathing slowly. It is a safe, accessible point for self-care.
