Wheat leaf, barley leaf, spearmint leaf, and manuka leaf are all certified organic.
We always try to source organic green pea, but when there is none available in New Zealand we use non-organic green pea. All harvested product is tested for residue and only used if no trace of chemical is found.
The boysenberry is not organic as they are susceptible to botrytis (fungus) if not managed with a fungicide which is applied at flowering (not on the actual fruit).
