[YEA] 12/28/2009: June from Cincinnati, Oh Usa: "I have a cardiac arrithymia since childhood. I am 54 now. I have researched and researched and researched after going to alot of cardiologists and trying mainstream remedies. I have tried magnesium, B vitamins, salt, potassium,etc. They all helped but did not cure my palpitations. My heart used to skip, and beat incredibly fast. I stopped going to the emergency room because they immediately wanted to do surgery, etc. The whole thing was terrifying. I cured this condition with one drop of REAL elemental Iodine in my orange juice in the morning. Sea kelp and drugstore Iodine did not work. Dr. Brownstein has written a book about it. You can tell if you are deficient by putting any iodine on the inside of your arm and watching to see if it lasts 24 hours. All my thyroid tests were normal. Every person I have told (who has arrithymia) has had a similiar experience!!!! One itsy bitsy drop of elemental iodine changed my life COMPLETELY. (I also paint my arm with it sometimes.)" http://www.earthclinic.com/Remedies/iodine.html
