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 (-1.14)
From 100% of the weighed grams.
Grams by band: cold 34%, cool 57%, warm 8%, hot 1%.
Small but decisive: Zhi Zi 45g (cold, 8% of the grams), Mang Xiao 45g (cold, 8% of the grams), Chang Shan 30g (cold, 5% of the grams), Ba Dou 8g (hot, 1% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 23%
- sweet 14%
- bitter 54%
- salty 9%
From 100% of the weighed grams.
Channels reached
- Stomach 74%
- Lung 66%
- Liver 31%
- Large intestine 30%
- Spleen 21%
- Heart 13%
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 powder, mix with honey and make into pills as size of phoenix tree seed, take 3 pills with hot water each time, then vomiting, diarrhea or sweating may occur, if not, take one pill again

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.
