Fragrances can do more than just smell good. They can affect relaxation, sensuality, happiness, and well-being.

Aromatherapy is the ancient practice of using oils from plants, herbs, and flowers to stimulate the olfactory sense to benefit the body physically, mentally, emotionally, and spiritually. It is based on folklore and anecdotal information, rather than on scientific studies. The newer field of aromachology, or olfactory science, however, rigorously studies the temporary effects of specific fragrances on human behavior, moods, and emotions. Scientists at leading universities, hospitals, and research centers are investigating many aspects of aromas.

Studies, many supported by the Olfactory Research Fund, have shown that pleasant odors can encourage helpfulness, creativity, and innovative problem solving. Some even contend that fragrances can help reduce anxiety during medical procedures. In particular, the scent of lemon has been shown to help clerical workers make fewer computer and word processing errors. Peppermint and lily of the valley are said to improve performance on tasks requiring sustained attention. Lavender is thought to aid relaxation and the sleep process.

Scientists have been able to quantitatively substantiate some of the claims made by aromatherapists over the years. Studies are advancing our understanding of fragrance and may point to a day when our medicine chests are as likely to be filled with aromas as with aspirin.
