The term essential refers to the essence of a plant, rather than an indispensable component of the oil or a vital biologic function. These organic compounds are a mixture of complex hydrocarbons that give the oil its aroma, therapeutic properties, and occasionally cause toxicity. More than 500 essential oils exist and can be categorized into five chemical groups: terpenes, quinines, substituted benzenes, aromatic/aliphatic esters, and phenols and aromatic/aliphatic alcohols.
