Aromatherapy and Essential Oils (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - General Information


Although essential oils are given orally or internally by aromatherapists in France and Germany, use is generally limited to inhalation or topical application in the United Kingdom and United States. Nonmedical use of essential oils is common in the flavoring and fragrance industries. Most essential oils have been classified as GRAS (generally recognized as safe), at specified concentration limits, by the U.S. Food and Drug Administration (FDA). (See the International Federation of Aromatherapists [] for a list of international aromatherapy programs.)

Aromatherapy products do not need approval by the FDA.
