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 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. There is some evidence that it is more effective than placebo in combating postoperative nausea and vomiting, but also that it is less effective than standard anti-emetic drugs.
