Essential Oil Defined
Source: Essential Oil.
An essential oil is a concentrated, hydrophobic (see definition) liquid containing volatile aroma compounds extracted from plants. They are also known as volatile or ethereal oils, or simply as the "oil of" the plant material from which they were extracted, such as oil of clove. An oil is "essential" in the sense that it carries a distinctive scent, or essence, of the plant. Essential oils do not as a group need to have any specific chemical properties in common, beyond conveying characteristic fragrances.
Hydrophobic Definition: In chemistry, hydrophobicity (from the combining form of water in Attic Greek hydro- and for fear phobos) refers to the physical property of a molecule (known as a hydrophobe) that is repelled from a mass of water.
Essential oils may be produced by distillation, expression, or solvent extraction. Essential oils are used in perfumery, aromatherapy, cosmetics, incense, medicine, household cleaning products, and for flavoring food and drink. They are valuable commodities in the fragrance and food industries. They are not to be confused with essential fatty acids.

Essential oil is distilled from plant material using water, steam or both. The process involves placing plant material over a grate and forcing steam through the grate. In the alternative, the plant material can be placed in boiling water. In either case, the heat from the steam and/or water causes the plant material to break apart and release an aromatic vapor. This vapor is condensed through cooling tubes into liquid form. This liquid is the essential oil of the plant, along with the hydrosol (water) of the plant.
The essential oil and hydrosol are then separated from one another and separately bottled for shipping and sale. Essential oils have remarkable qualities that enhance health, beauty and well being, helping to revitalize skin, encouraging radiance and resilience.
