Here I share my very favorite reference books, mobile apps and eBooks!
I’ve tried and tested many resources. Some were great, some… not so much. To help you in your journey to natural health and wellness, I'm listing some of my favorite references for you here.
You might wonder why we often look to third party sources for our essential oil education. dōTERRA does supply us with a great amount of valuable research and information, but because they sell oils, they are required to communicate in "compliant language" to comply with FDA rules regarding making drug claims. A source who does not market or sell essential oils has can communicate more freely under Freedom of Speech, using what I like to refer to as "plain English".
I personally use the reference materials I have listed here and shop these suppliers. I would never recommend anything that I don't love or use myself!

REFERENCE BOOKS

Essentials of the Earth
This spiral bound book is my favorite go-to for quick and easy use. It's a great reference guide, providing an overview, usage instructions, scientific explanations, safety charts, and an A-Z Guide of essential oils and health concerns.

Modern Essentials
An essential oil encyclopedia! It's a comprehensive guide to the therapeutic use of essential oils to safely address hundreds of health conditions. This detailed book covers everything from the basics, each individual oil and oil blends, personal care and spa, usage guides, and in-depth science section as well as a quick reference guide. The new 11th edition includes dōTERRA specific proprietary blend names, which is very helpful!

The Essential Life
A beautiful book with captivating images and details about each oil. To me this book is less of an encyclopedia, as it draws you in to turning each page to learn more. It has details about each oil, including suggested uses and recipes. The 5th edition has been updated with the new 2018 dōTERRA products.
