Here is Charlotte (Ann's mom, she's almost 90) reading about her oils in her Essential Oils Pocket Reference guide. You can get them on Amazon for about $25. The book shown below is the larger book, Essential Oils Desk Reference (all 800 pages of it). There is a TON of information in there but you'll pay a little more for it (about $70 on Amazon).
The information covers each individual oil and each oil blend. Invaluable!
