4.1 The Lung Channel System – Hand-taiyin(shou tai yin jing luo)

Location

On the radial aspect of the forearm, directly above the styloid

process of the radius, approximately 1.5 cun proximal to the

wrist joint space (wrist crease) in a V-shaped groove.

How to find

Place the palpating forefinger on the anatomical snuffbox

(➞ L.I.-5). From there, glide proximally over the styloid

process of the radius and locate LU-7where the finger can pal-

pate a cleft between two tendons (brachioradialis/abductor polli-

cis longus). Or:‘Tiger mouth grip’ (➞Fig. 2.6): spread the

thumb and forefinger of both hands, crossing them so that the

forefinger of one hand comes to rest on the styloid process of the

other, but avoiding bending the wrist. LU-7is located directly

below the tip of the forefinger in a V-shaped groove

Needling

Lift the skin above the styloid process by pinching it. Insert the

needle 0.5–1 cun obliquely and proximally (reducing) or distally

(tonifying). Caution: Cephalic vein.
