Why don't you write to Dr. Dale Loewen in Williams Lake BC.
He was a GP for 22 years before going into natural medicine. His office is called Total Health Centre. I'm sure he could give you lots of info and answer any questions you may have. This is what the College of Physicians in BC do. http://www.cpsbc.bc.ca/press/2003-10-17_loewen.htm I met him because of a heart attack in 1989. He took me off the drugs and we did chelation therapy with EDTA. I had real problems with the drugs but they all went away. I'm now on nothing and have completed my 61st journey around the sun. If it wasn't for this man I'd be dying of Canada's great health care system. Stay with natural medicine--it works!
