the book is very well written. I'm not an acupuncturist. But as a massage therapist I've found the information regarding the meridians, source points, how microcurrents flow and how they affect the body, to be useful in my daily practice.
also, I have a microcurrent unit that I use for myself. Because of the information in this book, I am now able to expand on the treatments I give myself and get even better results. And know why I'm doing something and what to expect from it.
So even though it's technically written for acupuncturists, the information can be broadly used by anyone with an interest in how energy flows through the body, how to affect that energy flow, and what to expect from energy restrictions before and after treatment.
