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 (-0.45)
From 100% of the weighed grams.
Grams by band: cold 36%, neutral 36%, warm 27%.
Pairs warm and cool. 27% of the weighed grams are warm or hot and 36% cool or cold — the net is their average, not the whole story.
Small but decisive: Mai Men Dong 10g (cold, 9% of the grams), Huang Qin 10g (cold, 9% of the grams), Di Gu Pi 10g (cold, 9% of the grams), Che Qian Zi 10g (cold, 9% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- sweet 64%
- bitter 21%
- bland 16%
From 100% of the weighed grams.
Channels reached
- Lung 86%
- Spleen 82%
- Heart 68%
- Kidney 59%
- Stomach 27%
- Liver 18%
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.
