Phytogenics are being used with increasing frequency, but many users are still uncertain on what constitutes this additive and its relation with essential oils.
Phytogenics are almost invariably compounds that belong to secondary plant metabolism. With that we mean that plants use these compounds for specific purposes. They do not participate in the daily or primary plant metabolism, such as that involving carbohydrate or protein synthesis, for example. Until some years ago, these secondary plant metabolism compounds were characterized as biologically insignificant because scientists thought they had no apparent function.
