A recent purchase for clinical use, this book is nothing more than a thinly veiled product manual for a company called Young Living Essential Oils (YLEO), a pyramid sales structured business that also happens to churn out some good quality therapeutic oils.
I should have taken clue #1: no opportunity to browse the book online prior to purchase, or, clue #2: no listing for either an author or an editorial staff that may have culled an Essential Oil Desk Reference worthy of academic study and clinical application at more than a YLEO sales or personal use level.
While a brief discussion of basic essential oils information occurs in passing, the overwhelming balance (and emphasis) of the text is directed toward and devoted to the YLEO product line.
In addition, about 1/3 of the book addresses non-essential oil topics including detox diets, herbal supplements, and lifestyle recommendations all of which, brace yourself dear reader, also happen to include YLEO product recommendations.
If you are using YLEO, it's a great tool. If you are seeking a true reference tool, look elsewhere.
