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 (-0.61)
From 100% of the weighed grams.
Grams by band: cold 20%, cool 45%, neutral 10%, warm 25%.
Small but decisive: Mu Tong 3g (cold, 6% of the grams), Dan Zhu Ye 2g (cold, 4% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 37%
- sweet 15%
- sour 2%
- bitter 44%
- bland 2%
From 100% of the weighed grams.
Channels reached
- Lung 78%
- Stomach 37%
- Spleen 29%
- Large intestine 25%
- Heart 25%
- Small intestine 20%
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.

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.
