Some essential oils such as tea tree[1] have demonstrated anti-microbial effects, but there is still a lack of clinical evidence demonstrating efficacy against bacterial, fungal, or viral infections. Evidence for the efficacy of aromatherapy in treating medical conditions remains poor, with a particular lack of studies employing rigorous methodology,[2] however some evidence exists that essential oils may have therapeutic potential.[3]

Aromatherapy may have origins in antiquity with the use of infused aromatic oils, made by macerating dried plant material in fatty oil, heating and then filtering. Many such 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.[4] Distilled essential oils have been employed as medicines since the invention of distillation in the eleventh century,[5] when Avicenna isolated essential oils using steam distillation.[6]

The concept of aromatherapy was first mooted by a small number of European scientists and doctors, in about[weasel words] 1907. In 1937, the word first appeared in print in a French book on the subject: Aromathérapie: Les Huiles Essentielles, Hormones Végétales by René-Maurice Gattefossé, a chemist. An English version was published in 1993.[7] In 1910, Gattefossé burned a hand very badly in a laboratory explosion. The hand developed gas gangrene, which he successfully, and intentionally, treated with lavender oil. [8]

Two basic mechanisms are offered to explain the purported effects. One is the influence of aroma on the brain, especially the limbic system through the olfactory system.[12] The other is the direct pharmacological effects of the essential oils.[13] While precise knowledge of the synergy between the body and aromatic oils is often claimed by aromatherapists, the efficacy of aromatherapy remains unproven. However, some preliminary clinical studies of aromatherapy in combination with other techniques show positive effects. Aromatherapy does not cure conditions, but helps the body to find a natural way to cure itself and improve immune response.[14][15]
