The best Antibiotic on planet Earth is Iodine sufficiency. If we have enough Iodine in our bodies, it is in the nose, lungs, saliva, stomach and it kills all virus & bacteria. These "bugs" never develop an immunity. Our immune system cannot function properly without iodine, and even uses Iodine to kill cancer cells by a process called Apoptosis. The more we learn about iodine, the more vital it is to our lives. Antibiotics devastate our immune system, because they kill everything including our own immune cells. I wish that all doctors were trained on iodine, but alas the drug companies will not allow it. http://tinyurl.com/iodine-references
