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

Location

3 cun lateral to the anterior midline and 2 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 2 cun in a cranial direction

(➞Ren-4) and, from there, measure 3 cun in a lateral direction.

There, locate qimen.

Located on the same level are ➞KID-13(0.5 cun lateral to the

midline), Ex-CA(yijing, 1 cun lateral to the midline), ➞ST-28

(2 cun lateral to the midline) and Ex-CA(tituo, 4 cun lateral to

the midline). ➞G.B.-27is located medial to the ASIS, approxi-

mately on the same level.

Needling

Vertically 0.5–1 cun. Caution: Peritoneum, pregnancy.

Actions/Indications

● Metrorrhagia, female infertility, orchitis, urinary tract infec-
