This an easy-to-read guide to aromatherapy. The authors, who have a combined 75 years of experience, present complex topics in a way that anyone can understand. This book is set up in four parts: theory, therapy, alchemy and materia medica. An important component of this book is the incorporation of herbal information - the more I learn about aromatherapy, the more I'm interested in herbs - that is not often included in a book about aromatherapy.
In the theory section, you will find information on the history and science behind aromatherapy, as well as the effects on the body and mind. In therapy, they cover guidelines for safely using essential oils - the safety information is good, but as always, I recommend getting a second opinion. Each system in the body is given its own section, alongside the essential oil therapies, herbal adjuncts are included. Section three, alchemy, teaches us about blending, extraction and the chemistry of essential oils. The final section, materia medica, includes the typical guide as well as one for Ayurvedic aromatherapy and a section on chakras. Throughout the chapters you will find recipes, but if that's all you're after this book isn't for you, as the bulk of the text is informational.
Overall, I would recommend this book to readers who are past the beginning level but not quite ready for advance study, in between the beginner and intermediate. Many of the concepts were repeats of what I've previously learned.
