I have arthirtis of the spine (ankylosing sponditis) and been told by doctors that there is no cure just PT. Dr Murray gives you an explanation of what went wrong, (while my disease is genetic why doesn't everyone with the gene get it?), nutritional vitamins and finally a diet to help and somewhat reverse the tide. Has it helped? In the two weeks I bought this book it has; my pain is less, much less, and while I am not totally faithful I am beginning to become a devout convert. If you have arthrits, ulcerative colitis (ra and uc are genetically related) or uncontrolled allergies, this man knows how to handle them. I've searched everywhere and he has the answer. Get this and the Balch Natural Remedies book and mate, you'll be right :-)
