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 (-0.44)
From 100% of the weighed grams.
Grams by band: cold 6%, cool 47%, neutral 33%, warm 14%.
Small but decisive: Da Huang 30g (cold, 6% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 43%
- sweet 14%
- sour 3%
- bitter 40%
From 100% of the weighed grams.
Channels reached
- Lung 81%
- Heart 39%
- Liver 36%
- Stomach 25%
- Spleen 25%
- Small intestine 14%
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.
Preparation
Grind to fine powder and form pills with egg white, each the size of a large bullet; dissolve one pill under the tongue and swallow at bedtime.
