ESSENTIAL OILS POCKET REFERENCE:  Newly updated! This pocket-sized version of the Essential Oils Desk Reference contains Personal Usage Guide (which features information and recommended essential oils and blends for over 300 different alphabetized health topics). It includes safety data, application information, and much more!  If you want to learn more about essential oils, this is the single, most powerful tool!  It is sold on Amazon, but I also sell it at my local Young Living meetings for $25.  I offer a discount to members in my personal organization who purchase the Premium Starter Kit.
