5.2 Ren mai
Location
On the anterior midline, 2 cun inferior to the umbilicus or 3 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 cun, which can
vary considerably from the patient’s finger cun. Therefore, only
proportional cun measurements should be used here (helpful
device: elastic tape ➞2.3.1). Ren-5is located on the midline,
2 cun inferior to the umbilicus. Located on the same level are
➞KID-14(0.5 cun lateral to the midline) and ➞ST-27(2 cun
lateral to the midline).
Needling
Vertically 0.5–1 cun. Caution: Peritoneum, pregnancy.
Actions/Indications

Special features
Front-mupoint of the Triple Burner. Some classic texts warn
that needling this point in women can lead to infertility (hence
the name: infertile women were referred to as ‘stone women’).
There are no such warnings in modern texts.
