Name and classical tradition

Luoque, 络却, admits several spellings and several readings. 絡 is the network of collaterals; 卻, to retreat, to turn back. The modern gloss understands that the Bladder channel enters the network of the brain here and then returns. No classical citation supports it. The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) records it with two of its aliases: "絡卻,一名強陽,一名腦蓋,在通天後一寸三分," one cun and three fen posterior to BL7.

More interesting is its philology. Among the ancient texts, the second character alternates between 卻 and 郄, and the alternative names are of very diverse meaning: the two from the Jiayi Jing, 強陽, "strong Yang," and 腦蓋, "lid of the brain," and others that the reference works add, 絡郄 and 反行, "the one that walks backward." The last is curious, because it fits the idea of retreat in the gloss. The exact provenance of each variant has not been identified.

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 BL8 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.
