I was diagnosed with arthritis of the spine which of course spread to every joint in my body about ten years ago. Having never been one to pop any type of pills, I did look for natural ways to combat this without checking with my physician an this was one of the books I used. I am not saying that the information is no good, it's just as they tell you it will work for some people and for some it will not. I was one that did not benefit from this. Whatever you do, never quit taking your medication unless you have the consent of your healthcare provider or they are aware that you are looking at alternative methods.
