Name and classical tradition

Muchuang, 目窗, is the "Eye Window": 目, eye, and 窗, window. The point lies on the scalp, in line with the pupil, and its name describes both its position and its use in eye disorders. The image is similar to that of its neighbor, GB15, which also looks toward the eyes from the top of the head.

Its alternate name has come down in three forms: 至营, 至荣, and 至宫. The final characters differ, and it is likely that two of them are copying errors from a single original, something common in manuscript transmission. Which form is correct can only be settled by a critical edition. Secondary sources trace it to the Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion).

Protocols for the 20 patterns you see most in practice

Each pattern with its tongue, its pulse, the treatment principle and the points to tonify and disperse. Made for the treatment table, not the bookshelf.

Do you use GB16 with your patients?

In the Clinic you record it in the patient's file, next to the tongue, the pulse and the measurements, so at the next session you know exactly what you used. The Atlas is built in.
