6.2 Extra Points: Chest and Abdomen (EX-CA)

Location

3 cun lateral to the anterior midline and 1 cun superior to the

upper border of the pubic symphysis.

How to find

The distance between the centre of the umbilicus and the upper

border of the pubic symphysis is divided into 5 proportional cun,

which can vary considerably from the patient’s finger cun.

Therefore, only proportional cun measurements should be used

(helpful device: elastic tape ➞2.3.1). From the upper border of

the pubic symphysis, measure 1 cun in a superior direction – this

is the location of ➞Ren-3. From there, measure 3 cun in a lat-

eral direction to locate zigong.

Located on the same level are ➞KID-12(0.5 cun from the

midline) and ➞ST-29(2 cun lateral to the midline).

Needling

0.5–1 cun vertically or 1–2 cun obliquely towards the upper

border of the pubic symphysis. Caution: Peritoneum, pregnancy,

full bladder.
