Most teas are not washed before being dried – and therefore non-organic teas almost certainly contain pesticide residues. Some tea brands (even those claimed organic or pesticide free!) have recently been found to contain pesticides that are known carcinogens – in quantities above the US and EU limits! This is completely outrageous. Now this vague terminology is a “blanket term” which conceals the truth of these ingredients. The term “Natural Flavors” essentially means flavorings “which have their origin in nature”. In other words, it could be made from any animal or plant source and processed in many ways.
