This book is packed with useful health advice, covering everything from nutrition to environment to relationships, all of which have an impact on health, according to Dr Galland. It covers so much ground that you really have to read it at least twice to take it all in and begin to act on it -- or, at any rate, I'll have to read it again! (In my case, I'll probably have to take notes to gain the full benefit of this book.)
This book shows that perhaps the greatest failing of modern, conventional medicine is the tendency not to listen to, and consider, the patients themselves: it focuses too much, he believes, on treating symptoms and diseases rather than people and the underlying causes of illness. He goes on to describe how the system can be improved; meanwhile, he tells people how they can help themselves.
The one thing that I felt was missing from this brilliant book was any mention of how the microwave fields generated by mobile phones (cellphones) & similar devices can make people sick -- and not just with cancer -- and, most importantly, how he believes we can deal with electrohypersensitivity and microwave sickness. (As humanity is flooding the planet with microwaves and making this subject ever-more important, perhaps he could devote a whole book to it.)
After reading "Power Healing" I can't wait to get my teeth into his next book, "The Allergy Solution" (due out in May 2016).
