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 (-1.42)
From 100% of the weighed grams.
Grams by band: cold 50%, cool 42%, neutral 8%.
Small but decisive: Di Gu Pi 9g (cold, 8% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- sweet 43%
- sour 7%
- bitter 37%
- salty 9%
- bland 4%
From 100% of the weighed grams.
Channels reached
- Kidney 72%
- Lung 58%
- Liver 58%
- Stomach 42%
- Heart 42%
- Spleen 28%
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.

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.
