Name and classical tradition

Quyuan, 曲垣, is the “curved wall.” 曲 is curved; 垣, the low wall, the garden wall. The spine of the scapula curves like a wall, and the point lies at its medial end. This is the morphological reading, the most solid and the most consistent with the set of shoulder blade names, in which SI11 is the celestial center and SI12 the wind. In Chinese astronomy, 垣 is also the name of the “enclosures” that bounded regions of the sky, which reinforces the reading of the set as a whole, although no ancient source expressly links it to the point.

A modern gloss circulates that reads 曲 as “hidden” and sees in the wall a mound of earth dust deposited by Qi. This is a strained reading, and there is no reason to prefer it to the anatomical one. The oldest known record is that of 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 SI13 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.
