Name and classical tradition

Zigong, 子宫, is the Chinese name for the uterus, literally the “palace of the child”: 子, the child; 宫 (宮), the palace. There are two points, three cun from CV3, Zhongji, four cun below the navel. It should not be confused with CV19, whose name is pronounced the same but written 紫宮, the Purple Palace.

The Zhenjiu Dacheng (Great Compendium of Acupuncture and Moxibustion) records it among the points outside the channels: “子宮二穴,在中極兩旁各開三寸,針二分,灸二七壯,治婦人久無子嗣” — three cun from Zhongji, for the woman who has gone a long time without conceiving. It is the same field as the lower abdomen of the Ren Mai, where CV4 and CV5 contended for the name of the cinnabar field.

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 EX-CA1 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.
