SI-7 - Branch of the Upright
支正 - Zhī zhèng
Point Region: Forearm
Location & How to Find
Anatomical Location: On the back and inner side of the forearm, between the inner edge of the ulna and the flexor carpi ulnaris muscle, 5 cun above the wrist crease on the back of the hand. It lies 1 cun below the midpoint of the line from SI-5 to SI-8.
Distances are in cun, a unit that scales with each person's body. As a guide, the width of your thumb at its joint is 1 cun, and your four fingers held together, measured across the middle joints, are 3 cun.
How to Locate:
- Find the midpoint between SI-5 at the wrist and SI-8 at the elbow, along the little-finger edge of the forearm
- Move one thumb-width down from it, toward the wrist
- The point is just beside the edge of the bone
How to Apply Pressure
After finding SI-7, relax your forearm and use soft, comfortable fingertip contact beside the edge of the bone rather than forceful kneading. Avoid it after recent arm surgery or an acute arm fracture, and consult a healthcare professional for severe anxiety.
