Most real estate agents know the importance of scents during open houses. It is not a mistake that when you enter an open house you are greated by the smell of fresh baked cookies or cloves and cinnamon simmering on the stove. I remember Peterson Nut company on Public Square used to vent the aroma of freshly baked nuts out onto the sidewalk. Aromatherapy is an inexpensive way to boost your mood or help you to relax. For example lavendar is a wonderful calming set. Placing a few drops on a cloth on the night stand can help a person relax enough to fall asleep. Bergamot, a scent from the citrus family, can be used as a mood booster and antidepressant. The following article by Dr. Chan provides some good background http://www.huffingtonpost.com/julie-chen-md/aromatherapy_b_3698319.html. Next time you are in Whole Foods or Earth Fare ask about and explore the world of essential oils.
