aromatherapy

aromatherapy

n. a type of therapy purported to improve psychological and physical health through the use of selected essential oils extracted from seeds, herbs, flowers, fruits, and trees. The fragrances of these oils are inhaled or the oils themselves are applied topically, using compresses, baths, or massages, in an effort to induce relaxation, reduce stress and emotional distress, and enhance well-being. Evidence supporting the effectiveness of aromatherapy is largely inconclusive. See also complementary and alternative medicine.
