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 neutral (-0.12)
From 100% of the weighed grams.
Grams by band: cold 15%, cool 28%, neutral 12%, warm 45%.
Pairs warm and cool. 45% of the weighed grams are warm or hot and 43% cool or cold — the net is their average, not the whole story.
Small but decisive: Huang Qin 21g (cold, 9% of the grams), Huang Lian 15g (cold, 6% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 26%
- sweet 34%
- bitter 40%
From 100% of the weighed grams.
Channels reached
- Spleen 70%
- Lung 51%
- Stomach 49%
- Liver 37%
- Heart 35%
- Gallbladder 33%
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
Fine powder, 9g as a draft; add a little shi gao in summer (source text).
