Hi friend. Look into MMS (Miracle Mineral Solution) aka Chlorine Dioxide. Its estimated that over 20 million people worldwide have used it. Its been shunned by the pharmaceutical industry as quackery, as they cannot patent or make money off of it. Its a weak oxidizer that when run thru the body, can destroy disease pathogens and they poisons they create, while doing no harm to the body. It destroys viruses, bacterial, fungus etc. NASA named chlorine dioxide "the universal antidote"
