Bests & Worsts Reviews from Amazon

If you are a Young Living user of their products, this is your BIBLE! It has everything you need in order to use the products wisely and effectively. I turn to it whenever I have a question regarding a health issue. For example: I have a cold with a nasty cough, what oil can I use? I look up cough in the book and they have recommendations with different oils and supplements. This is by far an extensive guide, highly recommend it!
