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 (-0.56)
From 100% of the weighed grams.
Grams by band: cold 20%, cool 44%, neutral 8%, warm 28%.
Pairs warm and cool. 28% of the weighed grams are warm or hot and 64% cool or cold — the net is their average, not the whole story.
Small but decisive: Yu Jin 3g (cold, 4% of the grams), Huang Qin 3g (cold, 4% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 33%
- sweet 15%
- sour 10%
- bitter 41%
From 100% of the weighed grams.
Channels reached
- Liver 72%
- Heart 64%
- Spleen 52%
- Lung 32%
- Kidney 20%
- Stomach 16%
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.
