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 slightly cool (-0.30)
From 100% of the weighed grams.
Grams by band: cold 30%, neutral 40%, warm 30%.
Pairs warm and cool. 30% of the weighed grams are warm or hot and 30% cool or cold — the net is their average, not the whole story.
Taste
- sweet 50%
- bitter 15%
- bland 35%
From 100% of the weighed grams.
Channels reached
- Kidney 85%
- Spleen 52%
- Lung 37%
- Heart 37%
- Stomach 15%
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
Decoct the ingredients with water for oral use

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.
Similar Formulas by composition
Match score combines dosage-weighted composition (cosine, 70%) with shared-herb overlap (Jaccard, 30%).
