陽池 (Yángchí) — Yang Pool
Triple Energiser channel · point 4
Traditionally used for
- Ears & hearing
- Pain & joints
Location
On the dorsal aspect of the wrist, in the depression on the ulnar side of the tendon of extensor digitorum communis, at the transverse crease.
How to locate: With the palm facing down, extend the fingers slightly to raise the extensor digitorum tendons; on the dorsal wrist crease, the point is in the depression on the ulnar side of these tendons, just radial to the extensor digiti minimi tendon.
Regional anatomy: Beneath the skin, subcutaneous tissue and deep fascia the needle runs between the tendons of extensor digitorum and extensor digiti minimi to the dorsal surface of the carpus.
Distances are in cun, a proportional unit — how to measure.
