I wanted to read this book through before i wrote a review...Well what can I say...It's been the best book I have read in this field by far,money well spent. Easy reading,although I wanted to take my time in reading it because I wanted to clearly understand every sentence I didn't really have to. It has helped me understand the way my body functions and has made me see Chinese medicine in a completely different way.My husband has strabismus and double vision and reading this book has helped us understand where the underlying problem is,quite amazing really. I would highly recommend this book,it really is worth buying. Five stars for me on this one.
