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 (+0.05)
From 100% of the weighed grams.
Grams by band: cold 7%, cool 28%, neutral 19%, warm 47%.
Pairs warm and cool. 47% of the weighed grams are warm or hot and 35% cool or cold — the net is their average, not the whole story.
Small but decisive: Qian Cao 9g (cold, 7% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- sweet 44%
- sour 5%
- bitter 23%
- salty 28%
From 100% of the weighed grams.
Channels reached
- Liver 63%
- Spleen 56%
- Kidney 47%
- Heart 44%
- Stomach 33%
- Gallbladder 19%
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.
