4 Acupuncture Points of the Twelve Primary Channels

Location

4 cun proximal to ➞T.B.-10(with the elbow flexed in a depres-

sion superior to the olecranon) or 5 cun proximal to the olecra-

non on a line connecting the olecranon and the lateral extremity

of the acromion (location of ➞T.B.-14).

How to find

First, locate the acromion (➞3.3.1). When the patient’s arm is

in abduction, two depressions will form below the acromion, in

the area of origin of the deltoid muscle. ➞T.B.-14is located in

the posterior depression, below the posterior aspect of the lateral

extremity of the acromion. Next, on a line connecting ➞T.B.-14

and the olecranon, measure 4 cun from ➞T.B.-10(1 cun proxi-

mal to the olecranon, in the depression that forms when the

elbow is flexed) in a proximal direction and there locate T.B.-12.

Or quick method:Spreading hands technique (➞2.3.3): Place

the little fingers on ➞T.B.-14and ➞T.B.-10respectively and

determine the midpoint of this distance with the thumbs. From

the midpoint, measure 1 cun in a distal direction and there locate

T.B.-12. For orientation: T.B.-12is midway between ➞T.B.-11

(1 cun proximal to T.B.-10or 2 cun proximal to the olecranon)

and ➞T.B.-13(3 cun distal to ➞T.B.-14, on the margin of the

deltoid muscle).

Needling

Vertically or obliquely up to 2 cun

Actions/Indications

● Opens the channel and alleviates pain

Special features

T.B.-12represents an area extending from 5–7 cun proximal to

the tip of the elbow rather than a discrete acupuncture point.

Determine the exact location by tenderness.
