While the term aromatherapy is sometimes misused to refer to many fragranced products, aromatherapy in the hands of a trained professional is a therapeutic technique using essential oils to promote health and well-being. Aromatherapy can increase energy, trigger relaxation, and reduce stress. Professional aromatherapy is part of the larger field of holistic medicine. Many aromatherapists are also herbalists.

Essential oils, which are the basis of aromatherapy, are highly concentrated derivatives of herbs and flowers. They contain the essence of the plants from which they come. In contrast, perfumed oils and fragranced oils are often synthesized from the plants, created in labs, or diluted.

A holistic approach means that a therapy deals with body, mind and spirit (energy). Only about five percent of essential oils available today are used in aromatherapy, and there are 10 to 15 that are the most commonly used. With few exceptions, essential oils should not be applied to the skin; they are best inhaled. Their aroma does the work.

To use essential oils for aromatherapy, only a few drops are needed. Common ways of dispensing aromatherapy oils are in a vaporizer, on a sachet, in potpourri, in bathwater, or in a lightbulb ring. While candles may emit fragrances thought to be therapeutic, they rarely contain actual essential oils.

Here are some of the typical uses and essences of aromatherapy. Bergamot is said to ease depression and anxiety (be careful if you put it in bathwater because it will temporarily make your skin more sensitive to sunlight). Chamomile is for alleviating insomnia and restlessness. Jasmine supposedly restores confidence and decreases apathy. Lemon is a stimulant that is said to improve memory and concentration. Lavender relieves stress and depression and enhances relaxation. Peppermint helps to eliminate fatigue. Both rose and jasmine are said to have aphrodisiac properties as well. Sandalwood helps to offset stress.
