I'm attending an evening class in aromatherapy and this book was recommended by the teacher. It has a nicely designed cover, and the typeface inside is clear and easily readable. It's designed as a working tome, and indeed I keep refering to it. The main body of the book is an alphabetical listing of oils, sometimes accompanied by a black and white line drawing of the plant in question. Each description is in a set pattern for quick reference and as well as telling you what it looks like and where it grows there is a lot of other info about how it is extracted what it's actions are, how to use it, any safety concerns etc. There's an interesting introduction for those of us new to using oils, a therapeutic index, a glossary and other good reference material. Possibly the only book you'll need for using aromatherapy in the home, unless you want to develop a much deeper understanding or skill, e.g. train as an aromatherapist. A really nice book to hold and flick through.
