4 Acupuncture Points of the Twelve Primary Channels

Location

Posterior to the ear, at the junction of the upper third with the

two lower thirds of the curved line connecting ➞G.B.-9and

➞G.B.-12.

How to find

First, locate ➞G.B.-9(1.5 cun superior to the apex of the ear

and 0.5 cun in a posterior direction). Then locate ➞G.B.-12in

a depression posterior and inferior to the mastoid process

(➞3.1.4). These two points are the endpoints of a curved line

that runs approximately parallel to the posterior margin of the

ear within the hairline. Divide this line into thirds and locate

G.B.-10at the junction of the upper and the middle third, where

often a small ‘dip’ can be felt on the bone. G.B.-10tends to be

on the level of the apex of the ear.

➞T.B.-20is located directly above the apex of the ear.
