It is widely thought that Aromatherapy began in Egypt. A medical papyri considered to date back to around 1555 BC contains remedies for all types of illnesses and the methods of application are similar to the ones used in Aromatherapy and Herbal medicine today.

Aromatherapy is a term coined by French chemist René Maurice Gattefossé in the 1920's to describe the practice of using essential oils taken from plants, flowers, roots, seeds in healing.

The term is a bit misleading, since the aromas of oils, whether natural or synthetic, are generally not themselves therapeutic. Aromas are used to identify the oils, to determine adulteration, and to stir the memory, but not to directly bring about a cure or healing. It is the "essence" of the oil or its chemical properties that gives it whatever therapeutic value the oil might have. Furthermore, vapors are used in some but not all cases of aromatherapy. In most cases, the oil is rubbed onto the skin or ingested in a tea or other liquid. Some aromatherapists even consider cooking with herbs a type of aromatherapy.
