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.
