[YEA] We removed a plantar wart from my preteen's foot with regular iodized table salt--the kind you get from the supermarket for less than 50 cents a canister. We had tried duct tape, ACV and banana peels, and the latter two did very clearly affect the wart, but it stubbornly remained. I did not wish to take my son to the doctor to have his wart frozen off, only to return, or cut out. After reading a suggestion here on Earth Clinic, we began soaking the affected part of his foot in a salt slurry for 10-20 minutes every day that we remembered or could get to it. It was very helpful to relieve his pain, and the wart became more black and scablike. After about 3 weeks of soaking, one evening my son's foot itched. He scratched at it absently, and a little cone-shaped piece of flesh (the wart) fell off in his hand. He had an equally tiny, cone-shaped indention in his foot with a little red dot at the bottom of it. We soaked his foot in the salt slurry a couple days more, just to make sure that little red dot could make no progress on any sinister intentions, but 4 months later, my son is still wart-free.
The salt slurry was never carefully measured -- just a little pile of salt poured onto a dish, with enough water to get it to the consistence of mud.
