Name and classical tradition

Youmen, 幽门, is the "dark gate" or "hidden gate." 幽 means hidden, dark, deep; 门 (門) is the gate. The point lies in the upper abdomen, at the level of CV14, Juque, and is the last of the abdominal stretch in which the Kidney channel and the Chong Mai rise together. A modern gloss explains that only a small part of the Qi continues upward from here, with no classical support.

The term 幽門 also designates, in modern Chinese anatomy, the pylorus, the outlet of the stomach, although there is no evidence that this usage is related to the origin of the point's name. The reference works give it the alternate names 上門, 上關, and 幽關. The first work to record it is 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 KI21 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.
