Name and classical tradition

Huiyang, 会阳, is the “meeting of Yang.” 会 (會) means to gather, to converge; 阳 (陽) is Yang. The point is beside the coccyx, and the convergence the name indicates is that of the Bladder channel with the Du Mai, both of a Yang nature. The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) confirms this by describing it as a place «督脈脈氣所發», where the Qi of the Du Mai emerges. It is, then, a point with a dual affiliation, and the name reflects a classical fact, not a late gloss.

The reference works give it the alternative name 利機, “favorable mechanism.” Very close by, on the midline, is GV1, Changqiang, the point where the Du Mai begins.

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 BL35 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.
