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 (-0.27)
From 100% of the weighed grams.
Grams by band: cold 27%, cool 9%, neutral 27%, warm 36%.
Pairs warm and cool. 36% of the weighed grams are warm or hot and 36% cool or cold — the net is their average, not the whole story.
Small but decisive: Huang Lian 5g (cold, 9% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 36%
- sweet 18%
- bitter 36%
- bland 9%
From 100% of the weighed grams.
Channels reached
- Lung 91%
- Spleen 91%
- Stomach 55%
- Heart 55%
- Large intestine 27%
- Gallbladder 27%
Share of the grams entering each channel, from 100% of the weighed grams.
1 herb without a dose in grams, so left out of every figure above: Sheng Jiang.
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, and take at a long interval before and after meals

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.
