Name and classical tradition

Fengmen, 风门, is the “wind gate.” 风 (風) is Wind in its medical sense, the pathogenic factor that enters from the outside; 门 (門) is the gate. The point is regarded as the place where Wind enters and leaves the body, a well-established concept in the classical nosology of Wind. The name is doctrine, not gloss.

The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) places it one and a half cun on each side of the space below the second thoracic vertebra. The reference works record the alternative name 熱府, “storehouse of heat,” the same one attributed to GB20, Fengchi, another Wind point. Together with Fengchi and GV16, Fengfu, it forms the series of points that carry Wind in their names on the nape and upper back.

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 BL12 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.
