Conception Vessel 3 is the third point on the Conception Vessel, one of the so-called ‘extraordinary’ acupuncture channels.

It is also the

  • Mu point (Alarm point) for the Bladder
  • Meeting point with Liver, Spleen and Kidney channels

Location of Zhongji

This point, Ren-3, lies 4 cun below the umbilicus on the mid-line.

 

Finding the point

Zhongji is usually where it says, ie 4/5 of the way from the umbilicus to the upper edge of the pubic bone.

But sometimes you have to search around for it. Start with Conception Vessel 2, locating it by pressing the tip of your finger against the superior edge of the pubic bone just to the side of the midline, and working it in towards the actual midline and beyond. By working back and forth you’ll eventually find the small dip in the centre, technically called the linea alba.

From there, work upwards towards the umbilicus, until you find a point that is either slightly or very tender to the touch (from the patient’s point of view) or seems tight to you, about 1/5 of the way up. That’s Conception Vessel 3.

 

Needling and Moxa on CV3

Conception Vessel 3 should not be needled on pregnant women!

Otherwise, either perpendicularly half to 1 cun, or diagonally from the side, up to 2 cun. Don’t go too deep because the bladder and uterus lie under the point. In any case, ask your patients to void their bladders first before using this point.

Sensation

Both in the area and downwards towards the urethra.
