How we scored it
Plant extract, no single molecule: all constituents are plant metabolites (n = 1), so natural fraction = 1.0. Extraction solvents and carriers leave no counted mass.
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
