If you continue to research this topic and its history and current use you should go to www.cigna.com and check out their pages on chelation therapy. They cover chelation for certain uses and not others. Where its use would conflict with group think in medicine, all the invasive and pharmaceutical based treatments, it is not covered. Look at the list of citations, all the standard groups that stand to lose market share of your medical dollars. They did not cite a recent Saunders medical textbook entitled Cardiovascular Drug Therapy containing a chapter entitled “Magnesium EDTA Chelation“ and it 65 references. Is that not interesting. Also keep in mind there are many chelating agents used for different problems. A recent book called Malignant Medical Myths, Why medical treatment causes 200,000 deaths in the USA each year, and how to protect yourself by Joel M. Kauffman, PhD and medical researcher is a must read for anyone who wants to understand enough about medicine to protect one’s self. It is available at www.buybooksontheweb.com.
