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

Cold Cool Neutral Warm Hot

Net slightly cool (-0.62)

From 100% of the weighed grams.

Grams by band: cold 48%, neutral 19%, warm 33%.
