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 warm (+0.48)
From 100% of the weighed grams.
Grams by band: cold 7%, cool 11%, neutral 15%, warm 59%, hot 7%.
Small but decisive: Mai Men Dong 10g (cold, 7% of the grams), Rou Gui 10g (hot, 7% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 30%
- sweet 41%
- bitter 26%
- bland 4%
From 100% of the weighed grams.
Channels reached
- Heart 100%
- Spleen 74%
- Liver 52%
- Lung 41%
- Kidney 33%
- Stomach 15%
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.
