Does iodine kill gram positive and gram negative organisms?

Answer: yes. In his article "The End of Antibiotics and the Rise of Iodine as an Effective Alternative" Mark Sircus, OMD, says "Though it kills 90 percent of bacteria on the skin within 90 seconds, its use as an antibiotic has been ignored. Iodine exhibits activity against bacteria, molds, yeasts, protozoa, and many viruses; indeed, of all antiseptic preparations suitable for direct use on humans and animals and upon tissues, only iodine is capable of killing all classes of pathogens: gram-positive and gram-negative bacteria, mycobacteria, fungi, yeasts, viruses and protozoa. Most bacteria are killed within 15 to 30 seconds of contact." See the full article at
