Charity......There's a couple of things you can do naturally even though your doctors probably would disagree....First theres EDTA which some alternative medicine doctors will give by IV Drip. However you can buy this at the health food stores in a powder form and drink it. One Product i know of is the ''Royal Arterial Flush Kit''. Secondly high doses of Magnesium keeps Calcium in check so i'd take 1000 mg a day and not take any Calcium except in foods. Thirdly although not sure how true this would work but read about it and that is upon waking up in the morning drink 2 full glasses of Distilled water on an empty stomach and no other food/liquids for an hour as the distilled water will attach Calcium and other metals and flush them out of your body over time...So there's a few ideas what to do naturally about your question....
