Aromatherapy is based on the use of aromatic materials, including essential oils and other aroma compounds, with claims for improving psychological well-being. It is offered as a complementary therapy or as a form of alternative medicine. Fragrances used in aromatherapy are not approved as prescription drugs in the United States. People may use blends of essential oils as topical application, massage, inhalation, or water immersion. There is no good medical evidence that aromatherapy can either prevent, treat or cure any disease. There is disputed evidence that it may be effective in combating postoperative nausea and vomiting.

Distilled cedarwood oil was used by the ancient Egyptians, and the process of distilling essential oils like rose essence was refined by the 11th century Persian scholar Ibn Sina.
