People commonly think that "aromatherapy" refers to anything that smells good, like scented candles, potpourri, and perfumes. We use the term "aromatherapy" to refer to the therapeutic application of plant essential oils (usually diluted in some type of solution) by qualified aromatherapists or other individuals.

There is a growing body of research from laboratory and clinical studies that points to the remarkable healing properties of essential oils. They are widely available in markets, co-ops, and pharmacies and are increasingly used in clinics and hospitals.
