I agree that the medically community rather treat diseases rather than cure them, but in order to treat them the disease has to be scientifically proven. If they can prove the condition of Cushing's, I see no reason they couldn't prove the existence of "AF" if it were real. I see no reason they wouldn't want that to be a real disease so they can start charging people to treat it.
Do you really think the AMA and big pharma wants alternative medicine to have the monopoly in treating a disease? No way!
