This so impressed me that I made sure that aromatherapy was included as a facilitation technique in my book, Therapeutic Recreation Processes and Techniques (5th edition).
Yesterday, while at the IU Med Center Bookstore, I found another resource on aromatherapy. I thought I should pass it on to others. It is a 4-page laminated resource by Permacharts. For $3.95 a wealth of information is provided on aromatherapy.
