5.3 Du mai
Location
On the occiput, on the posterior midline, in the depression
between the 1st (atlas) and 2nd (axis) cervical vertebrae, approx-
imately 0.5 cun inferior to ➞Du-16(directly below the external
occipital protuberance).
How to find
The external occipital protuberance (➞3.1.5) is a hump-shaped
projection on the posterior surface of the occipital bone, on
the midline and slightly superior to the craniocervical junction
(➞3.1.5). ➞Du-16is located in a depression on the posterior
midline that you can palpate directly inferior to the protuber-
ance. From there, glide 0.5 cun in an inferior direction and locate
Du-15superior to the first palpable spinous process (belonging
to the axis; the atlas has no spinous process) and approximately
0.5 cun superior to the posteror hairline.
Located on the same level is ➞BL-10(on the lateral aspect of
the trapezius muscle).
Needling
0.5–1 cun strictly perpendicularly in an inferior direction. Cau-
tion: Injury to the cervical marrow. According to classic texts,
moxibustion is contraindicated.
