Aromatherapy uses plant materials and aromatic plant oils, including essential oils, and other aroma compounds for improving psychological or physical well-being.

It can be offered as a complementary therapy or, more controversially, as a form of alternative medicine. Complementary therapy can be offered alongside standard treatment, with alternative medicine offered instead of conventional, evidence-based treatments.

Aromatherapists, who specialize in the practice of aromatherapy, utilize blends of therapeutic essential oils that can be issued through topical application, massage, inhalation or water immersion to stimulate a desired response.

There is no good medical evidence that aromatherapy can either prevent or cure any disease, but it might help improve general well-being.

The use of essential oils for therapeutic, spiritual, hygienic and ritualistic purposes goes back to a number of ancient civilizations including the Chinese, Indians, Egyptians, Greeks, and Romans who used them in cosmetics, perfumes and drugs.

Oils are described by Dioscorides, along with beliefs of the time regarding their healing properties, in his De Materia Medica, written in the first century. Distilled essential oils have been employed as medicines since the invention of distillation in the eleventh century, when Avicenna isolated essential oils using steam distillation.

The concept of aromatherapy was first mooted by a small number of European scientists and doctors, in about 1907. In 1937, the word first appeared in print in a French book on the subject: Aromathérapie: Les Huiles Essentielles, Hormones Végétales by , a chemist. An English version was published in 1993. In 1910, Gattefossé burned a hand very badly and later claimed he treated it effectively with lavender oil.

A French surgeon, , pioneered the medicinal uses of essential oils, which he used as antiseptics in the treatment of wounded soldiers during World War II.
