Chelation is used by alternative and mainstream medicine.
There are many useful natural herbs that have been proven to work for thousands of years in Other medical modalities besides the current medical structure. I have a chronic disease the allopathic doctor could not help. I went to an ayurvedic doctor, he is practicing a medicine that is based on scientific principles and the accumulated knowledge of thousands of years. I saw results within the first week. Where as the allopathic doctor basically told me to hang up my hat.
I fail to see how diet exclusions are expensive or dangerous, if anything you should be saving money. This just goes to show the duplicity and doublespeak involved in allopathic medicine. It's the Ole we can't find anything wrong with McDonalds ...so it must be OK. Most doctors I've dealt with know very little about nutrition.
