4.2 The Large Intestine Channel System – Hand yangming(shou yang ming jing luo)

Location

In the depression distal and anterior to the acromion, between

the clavicular and acromial portions of the deltoid muscle.

Ask the patient to abduct their arm. With the arm in a horizontal

position, two depressions will form in the insertion area of the

deltoid, distally to the acromion. By placing the thumb and

index finger in those depressions in a pincer-like grip (with

thumb and finger 1 thumb’s breadth apart), the anterior finger

will be in the anterior depression, where L.I.-15is located.

➞T.B.-14is located under the posterior finger in the dorsal

depression.

Needling

cleft and in a posterior direction; with the arm abducted, 0.5–1

cun vertically. Caution: Shoulder joint.
