While a regulatory system for raw plant materials used in individual dispensing would be difficult and impractical to implement, plant materials identified as toxic should be subjected to specific regulatory procedures. Plant materials classified as toxic should be dispensed only by appropriately qualified practitioners.

At all levels of handling of raw plant materials, clear and accurate identification and labelling is paramount. Countries should also give consideration to mechanisms for controlling contamination of raw plant materials with pests, microorganisms, aflatoxins and other mycotoxins, pesticides, heavy metals and other foreign matters.
