Essential oils are compounds extracted from plants. The oils capture the plant's scent and flavour, also referred to as its “essence" Unique aromatic compounds give each essential oil its characteristic essence. Essential oils are obtained through distillation (via steam and/or water). Once the aromatic chemicals have been extracted, they are combined with a carrier oil to create a product that's ready for use. The way the oils are produced us extremely important, as essential oils obtained through chemical processes are not considered true essential oils.
