Commentary

Bizhong EX-UE is not a major Extra point. Its name function is to open the local Channel and Luo Vessel. 

Classical Sources

The point was first documented in the Tang Dynasty text Beiji Qianjin Yaofang (備急千金要方, Essential Prescriptions Worth a Thousand Gold) by Sun Simiao, where it was named 'Shounizhu' (手逆注, Hand Reverse Flow). The modern name 'Bizhong' (臂中, Middle of Arm) was established in the contemporary text Xin Yiliao Fa Shouce (新医疗法手册, New Medical Methods Handbook).

The classical verse states: "臂中肘腕伸有数,两筋之间凹陷处" (Bizhong lies at the measured midpoint between elbow and wrist, in the depression between two tendons).

How to Locate

The patient's forearm should be in a relaxed supinated position. The wrist joint space is a more reliable reference point than wrist crease to identify Bizhong EX-UE. Draw an imaginary line between the midpoint of the wrist joint space and cubital crease. Identify Bizhong EX-UE in the middle of these two point, between the ulna and radius.

Caution

The point lies near the median nerve and the anterior interosseous nerve, as well as the median artery and vein. While not classified as dangerous, practitioners should needle carefully to avoid nerve irritation. Avoid excessive manipulation if the patient reports sharp or electrical sensations radiating down the arm, as this may indicate nerve contact.
