To find a doctor in your area that does Chelation Therapy, go to http://www.acam.org/. That is the home page of the American College for Advancement in Medicine.
The web site also has information on books to read about the benefits of EDTA.
"Bypassing Bypass Surgery" By Elmer M. Cranton, MD is one of the books I read many years ago and I would highly recommend reading it.
From things that I have read in the past is that if you have a serious problem, the intravenous EDTA method works faster. I have tried the oral EDTA and did not see any benefit from it.
