4 Acupuncture Points of the Twelve Primary Channels

Location

3 cun proximal to the dorsal wrist joint space (‘dorsal wrist

crease’), in a depression between the radius and the ulna, radial

to the tendon of the extensor digitorum communis muscle.

How to find

As the location of the dorsal wrist crease varies, the wrist joint

space should be used for orientation instead (➞3.3.3). By mov-

ing the patient’s wrist in a relaxed way, the joint space becomes

more easily palpable. From the joint space, measure 3 cun in a

proximal direction. At this point, the extensor digitorum com-

munis muscle will often lie midway between the ulna and the

radius. T.B.-6is located in a depression close to the border of the

radius, on the radial side of the muscle.

Located on the same level is ➞T.B.-7,in a depression between

the ulna and the extensor digitorum communis muscle. ➞P-5

is also located on this level, but on the anterior aspect of the

forearm.

Needling

0.5–1.5 cun slightly obliquely towards the ulna or obliquely in a

proximal (elbow) or distal (wrist) direction. Or through-needling

to P-5(jianshi). Caution: Movement of the hand/arm during

needle retention may cause bending of the needle.
