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 (-0.59)
From 100% of the weighed grams.
Grams by band: cold 47%, neutral 19%, warm 34%.
Pairs warm and cool. 34% of the weighed grams are warm or hot and 47% cool or cold — the net is their average, not the whole story.
Small but decisive: Hu Huang Lian 3g (cold, 10% of the grams), Huang Bai 2.4g (cold, 8% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 19%
- sour 19%
- bitter 61%
From 100% of the weighed grams.
Channels reached
- Large intestine 95%
- Stomach 73%
- Liver 29%
- Spleen 24%
- Lung 19%
- Kidney 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.
