Humans have used aromatherapy for thousands of years. Ancient cultures in China, India, Egypt, and elsewhere incorporated aromatic plant components in resins, balms, and oils. These natural substances were used for medical and religious purposes. They were known to have both physical and psychological benefits.

Essential oils distillation is attributed to the Persians in the 10th century, though the practice may have been in use for a long time prior to this. Information about essential oil distillation was published in the 16th century in Germany. French physicians in the 19th century recognized the potential of essential oils in treating disease.

Medical doctors became more established in the 19th century and focused on using chemical drugs. However, the French and German doctors still recognized the role of natural botanicals in treating illness.

The term “aromatherapy” was coined by a French perfumer and chemist René-Maurice Gattefossé in a book he wrote on the topic that was published in 1937. He had previously discovered the healing potential of lavender in treating burns. The book discusses the use of essential oils in treating medical conditions.
