Composition
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
Net cool (-1.00)
From 100% of the weighed grams.
Grams by band: cool 100%.
Taste
- pungent 100%
From 100% of the weighed grams.
Channels reached
- Lung 100%
- Liver 100%
Share of the grams entering each channel, from 100% of the weighed grams.
2 herbs without a dose in grams, so left out of every figure above: Hua Shi, Gan Cao.
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.

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.
