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 warm (+1.06)
From 100% of the weighed grams.
Grams by band: warm 94%, hot 6%.
Small but decisive: Wu Zhu Yu 30g (hot, 6% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 74%
- sweet 6%
- sour 6%
- bitter 15%
From 100% of the weighed grams.
Channels reached
- Spleen 88%
- Stomach 65%
- Lung 59%
- Kidney 41%
- Large intestine 12%
- Heart 12%
Share of the grams entering each channel, from 100% of the weighed grams.
