Comments on Conception Vessel 9

I don’t usually needle this point on its own. I combine it with other points like Bladder 20.

However, moxa here on its own can be very effective, either with cones or with heat from a lighted ‘cigar’ of moxa punk.

Conception Vessel 9 is said to open the waterways between the Middle Jiao (the Middle ‘Burning Space’, being the space above the umbilicus level and below the diaphragm) and the Lower Jiao, (the abdominal space inferior to the level of the umbilicus).

It helps the body separate out the ‘clear’ from the ‘turbid’, and works well with the Lung and Colon channels, using points such as Lung 7 and Kidney 6. Another good combination for Damp is with Spleen 9 Yinlingquan.

In some ways, this is a diuretic point which means it helps you pee, so clearing Damp from the system. (Some patients need to access the toilet urgently after you use this point for them.)

Damp has many forms, one of which is mucus, and using this point with Bladder 20 helps to disperse it.
