Name and classical tradition

Chongmen, 冲门, is the “Surging Gate.” 冲 refers to an obligatory, strategic passage, and also to the impulse to advance with force; 门 is the gate. The point lies in the groin, in the area the classics called 氣街 (Qi Street), a crucial passage between the trunk and the leg. Hence the reading of a gate on a main thoroughfare. A modern gloss adds that the Qi rising through the leg surges here toward the abdomen, with no citation to support it.

Secondary sources attribute it to the Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) and consider it a crossing point of the Spleen channel with the Liver channel. They also record two alternative names, 慈宫, “Palace of Compassion,” and 上慈宫, which sources repeat consistently although without any ancient citation.

Despite sharing the character 冲, Chongmen is not the Chong Mai, the Extraordinary Vessel. In the same inguinal area, the Stomach channel has ST30, Qichong, which tradition regards as the origin of that vessel.

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 SP12 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.
