Wow, what an interesting book. I always thought dowsing was a myth until a friend gave me this book and urged me to read it. I suffer from poor health including allergies which has made my life miserable at times. I was always looking for ways to improve my health so was prepared to give dowseing a go. What fabulous results it has brought to my life! I have been able to identify several supplements which had an almost immediate impact on improving my health. I also have a knowledge of what food groups to avoid to keep individual problems at bay. Fantastic!
