I ask about sulfur (sorry I misspelled the title) because I was watching an episode of Jericho, and there was a list of needed items on the show. The list was: (what I can remember) Salt Morphine Antibiotics Iodine Sulfur I understand the others completely, but why sulphur? What can it be used for, and how can you get it? And Iodine?..... just an antiseptic right?
