That's a very good question. One of the keys to the "Mini Kit" concept is to get multiple uses from a single item. Iodine based water purification tablets do produce a mildly antiseptic solution in water, after all that is their intended purpose. It would certainly be better to clean or irrigate a wound with treated water than risk introducing other little bugs, critters and nasties from untreated water. I would still use the 2 tablets per quart of water recipe. Don't use this on someone who is sensitive or allergic to iodine.<br><br>
