Energetics dose-weighted
The formula's overall nature, taste balance and channel reach, weighted by each herb's dose. Classical formulas often pair warm and cool herbs on purpose, so a net figure summarises the mix — it doesn't describe every herb in it.
Nature

From 100% of the weighed grams.
Grams by band: cold 38%, cool 31%, warm 31%.
Pairs warm and cool. 31% of the weighed grams are warm or hot and 69% cool or cold — the net is their average, not the whole story.

From 100% of the weighed grams.
Channels reached
- Stomach 81%
- Lung 63%

- Liver 19%
Share of the grams entering each channel, from 100% of the weighed grams.
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
Cook in 8 cups of Lao Shui (water ladled in and out of a pail 1,000 times until bubbly) until reduced to one-third; take warm, strained, in three doses daily. Bracketed doses may be used today.

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.
