Chelation therapy helps improve conditions associated with poor circulation or atherosclerosis, including slow-healing wounds, by providing the antioxidant ethylenediaminetetraacetic acid, which goes into the bloodstream and clings to iron, lead and other heavy metals that cause free radical harm to the arteries, explains the Rothfeld Center. The antioxidant brings the heavy metals with it when the body flushes it through urine, thus decreasing harmful metal buildup, delaying the progress of atherosclerosis and restoring healthy blood flow.
Additionally, EDTA enhances the responsiveness and dilation of artery walls by getting rid of extra calcium in the walls, notes the Rothfeld Center. This benefit helps restore the function of arteries and improve blood circulation. Other benefits of chelation include thinning the blood and preventing the creation of harmful blood clots that contribute to heart problems.
During a chelation treatment, a doctor gradually administers EDTA intravenously while the patient sits in a recliner, states the Rothfeld Center. The process takes 90 minutes to three hours, and a full course of treatment involves up to 30 sessions.
Slow wound healing is a symptom of peripheral artery disease, in which plaque leads to poor circulation and causes leg arteries to narrow, according to WebMD. Peripheral artery disease is one of the main types of cardiovascular disease that results from the plaques of atherosclerosis.
