4 Acupuncture Points of the Twelve Primary Channels

Location

Lateral to the radial artery, 1 cun proximal to the ventral wrist

joint space (most distal wrist crease).

How to find

As the location of the wrist crease varies, use the joint space

(➞ 3.3.3) between the proximal row of carpals and the

radius/ulna for orientation. By loosely moving the hand, the

joint space is easily palpable. This is the level for palpating the

radial pulse (using the finger tips, not the finger pads). ➞LU-9

is located on the radial side of the artery, while LU-8is located

1 cun proximal to ➞LU-9.

➞L.I.-5is located close to LU-8, but on the dorsal aspect of the

wrist joint in the anatomical snuffbox.

Needling

0.3–0.5 cun proximally or vertically. Avoid the radial artery

by gently pushing it to the side when palpating for the point.

Moxibustion is contraindicated according to some classics.
