Great Luo
3 points · study category
The Great Luo points don't link a channel with its paired channel. Each one governs an entire collateral network: the Great Luo of the Ren Mai waters the abdomen, that of the Du Mai the back, and that of the Spleen the lateral band of the chest. They are separate from the twelve connecting Luo points, which is why the Spleen has a Luo point (SP4) and also a Great Luo (SP21).
