Jing-River point, not the Yuan-Source point (LI4). It is Nakatani's representative point.

Name and classical tradition

Yangxi, 陽谿, is the “yang stream.” 陽 indicates the dorsal side of the hand, which is yang; 谿, also written 溪, is a stream or ravine, the word the nomenclature uses for narrow depressions between tendons or bones. Here the stream is the anatomical snuffbox, the hollow that forms at the wrist between the thumb tendons when the thumb is extended.

The Lingshu (Spiritual Pivot), chapter Ben Shu (本輸), describes it in those same terms: “行於陽谿,陽谿在兩筋間陷者中,為經.” The qi travels through Yangxi, in the depression between the two tendons; it is the Jing-River point (經穴). On the yang channels, the Jing-River point corresponds to Fire. After the “passing” at LI4, the verb is now “traveling,” the verb for the regular course of a river.

The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) gives it the alternative name 中魁, so the alias is ancient.

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 LI5 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.
