List of essential oils

Essential oils are plant oils extracted by distillation. The principal uses of essential oils are as flavoring agents, and medical and aromatherapy applications. Essential oils should not be confused with macerated oils, where plant materials are infused in a base oil. Tarragon oil, for example, is oil distilled from the tarragon plant. Tarragon leaves in olive oil are sometimes used in cooking, and can also be called tarragon oil.
