How we scored it
Dried, ground inner bark: whole plant material, all mass plant-derived, so 1.0. No synthetic fragments.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Inner bark of Uncaria tomentosa, harvested mainly in Peru, is dried and milled. No synthetic route exists for this plant material.
In plain English
