This portable version of the larger Modern Essentials book is the perfect choice for taking information with you when you are out enjoying nature, on trips, or visiting clients. Its small size makes this book easy to slip into a purse, carrying case, or suitcase, and its coil binding allows easy access to the information when you need it most. This book contains the Personal Usage Guide section with commonly used oils and application methods, along with the Science and Application section, containing detailed information on the history, science, and proper application of essential oils—with detailed instruction on how to perform the AromaTouch Technique. Not all of the information contained in the large book, Modern Essentials, is in this book. This book only has 2 of the 6 major sections contained in the large book.
