I first came across this book at an acupuncture conference in 1996. It was one of my best purchases of the year. The book covers in depth, a topic only glanced upon in most acupuncture schools. The technique is not just for acupuncturists. I believe it’s a must read for massage professionals, especially if your hands are starting to wear out from years of giving massage. After reading it, I have confidently expanded Gua sha to every sort of muscular injury with great results. I have saved a number of people from exploratory surgery by removing pains of unknown etiology, thru the use of this technique and proper muscle knowledge. This is why I recommend it for massage therapists, physical therapists as well as Oriental and TCM practitioners.
