Query: Aromatherapy Lacking

As a person who has had an interest in aromatherapy for many years, I found this book lacking in useful information and practical recipes. There were some very inspirational stories that I enjoyed reading, but got the feeling that this book was a bit of an advertisement for the authors company. For the person who is looking for more useable information, there are too many other books out there that give more insight."
