Essential oils are concentrated, hydrophobic liquids containing volatile (readily evaporate) chemical compounds extracted from plant material. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that the oil contains the fragrance or essence of the plant. The term "essential" used here does not indicate that it is nutritionally required in the diet, as with essential amino acid or essential fatty acid.
Essential oils are most commonly extracted by steam distillation. Other processes include expression, solvent extraction, sfumatura, and cold pressing. They are used in perfumes, cosmetics, soaps, air fresheners and other products, for flavoring food and drink, and for adding scents to household cleaning products.
