This is the book that always comes to the forefront when people look for aromatherapy books. Heck, it was even in my health food store. This book is disjointed, assumes you have oodles of money for 50 plus oils, and gives vague instructions on the way to use these. It may be clear if you already know about this subject. For me, I need a step by step understanding of how to proceed. That is not what you get in this book.For the beginner Kathi Keville is the way to go. (Aromatherapy for Dummies, or Aromatherapy the Complete Guide to the Healing Art).
