3 herbs without a dose in grams, so left out of every figure above: Hou Po, Lai Fu Zi, Mang Xiao.
Dose-weighted from each herb's recorded nature, taste and channels (missing values are left out, never counted as neutral). It describes the composition — it is not a recommendation.
Preparation
Decoct, adding Da Huang near the end; dissolve Mang Xiao in the strained decoction. For intestinal obstruction the first dose may be given by nasogastric tube and a second as an enema 2-3 hours later.

Formula family
Each entry reads as the larger formula written out: “+” adds its other catalogue cores, then the herbs none of them hold. A catalogue formula counts as a core only when at least 80% of its herbs are present, no more than 1 is absent, and the absent herb is not its chief.
