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 (+0.24)
From 100% of the weighed grams.
Grams by band: cool 48%, neutral 16%, hot 36%.
Pairs warm and cool. 36% of the weighed grams are warm or hot and 48% cool or cold — the net is their average, not the whole story.
Taste
- pungent 48%
- sweet 28%
- bitter 24%
From 100% of the weighed grams.
Channels reached
- Spleen 100%
- Stomach 76%
- Heart 52%
- Gallbladder 48%
- Liver 48%
- Lung 28%
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.

Formula family
Each entry reads as the larger formula written out: “+” adds its other catalogue cores, then the herbs none of them hold. A catalogue formula counts as a core only when at least 80% of its herbs are present, no more than 1 is absent, and the absent herb is not its chief.
