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 fingertips, not the finger pads). ➞ LU-9 is located on the radial side of the artery, while LU-8 is located 1 cun proximal to ➞ LU-9. ➞ L.I.-5 is 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.
