4 Acupuncture Points of the Twelve Primary Channels

Location

5 cun proximal to the anterior space of the wrist joint (most distal

wrist crease), between the tendons of the palmaris longus and

flexor carpi radialis muscles.

How to find

Spreading hands technique (➞2.3.3): Place the little fingers in

the centre of the anterior wrist joint space (➞3.3.3, ➞P-7) and

the cubital crease respectively (➞P-3). From the midpoint of

this distance, measure 1 cun in a distal direction. On this level,

locate P-4between the two tendons, which become more pro-

nounced when the fingertips are pressed together. If only one

tendon is visible, this will be the tendon of the flexor carpi radialis

muscle. P-4is located on its ulnar aspect.

Needling

0.5–1 cun vertically or 1–1.5 cun obliquely in a proximal direction.
