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 warm (+0.77)
From 100% of the weighed grams.
Grams by band: cold 10%, cool 10%, neutral 7%, warm 42%, hot 32%.
Small but decisive: Qing Fen 9g (cold, 10% of the grams), Chuan Wu 9g (hot, 10% of the grams), Rou Gui 3g (hot, 3% of the grams), Hu Jiao 3g (hot, 3% of the grams), Gao Liang Jiang 3g (hot, 3% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 65%
- sweet 2%
- bitter 21%
- salty 13%
From 100% of the weighed grams.
Channels reached
- Liver 71%
- Spleen 61%
- Heart 45%
- Stomach 39%
- Large intestine 29%
- Kidney 26%
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
Grind the ingredients into extremely-fine powder, dust it on the plaster, and paste on the affected area

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.
