Query: Great Book

I've read some of the bad reviews but I think that this book, like any other book, is just an opener to the great uses of essential oils. Many complaints are due to the fact that many readers did not take the time to further research exactly what they needed and just expected this book to provide answers to thier varied problems. Personally, I have found this book to be of great help for myself, my customers, family and friends. There is a great receipe for in-grown hairs, herbal teas and preventative measures for acne. NO this is not an answer all book but it has been useful to my business. The herb salve that I now make has gotten rave reviews. I not only used this book as a reference, but I also did further research to ensure that the information was valid.
