The condition of this book is very good but it has some scuffs from shelf storage and a taped page. Please view the photos for visual details of condition. The mini Modern Essentials Usage Guide is a softcover, condensed version of the larger, hardcover Modern Essentials: A Contemporary Guide to the Therapeutic Use of Essential Oils. The smaller size and coil binding make this portable reference perfect to carry in a purse or case wherever you go?outdoors, traveling, or visiting clients. The usage guide contains the complete "Personal Usage Guide" from the hardcover book (conditions, oils, and applications methods). Condensed sections from the larger book include "Single Essential Oils" (primary uses and application methods) and "The Science and Application of Essential Oils" (introduction, history, chemistry, charts, and proper use).
