4 Acupuncture Points of the Twelve Primary Channels
Location
3 cun below the umbilicus or 2 cun above the upper border of the
pubic symphysis and 2 cun lateral to the anterior midline.
How to find
The distance between 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 tool:
elastic tape ➞2.3.1). From the upper border of the pubic sym-
physis, measure 2 cun up or measure 3 cun down from the
umbilicus. ST-28is located 2 cun laterally from there.
Located on the same level are ➞Ren-4(anterior midline),
➞KID-13(0.5 cun lateral to the anterior midline) and ➞Ex-CA
(tituo/quimen/yijing; 4/3/1 cun lateral to the anterior midline).
Needling
Vertically 0.5–1 cun. Caution: Peritoneum, urinary bladder,
pregnancy.
