there are hundreds of these folk medicine "cures" but i don't think you are going to have much success in curing your plantar warts with a potato. unless of course your bury the potato under a full moon (just kidding).
potato in half rub on planter wart for a few weeks? . when i was a kid i had. i had a planter wart on my big toe. i remember at the time my parents took a potato and did not peel it they cut in half and rubbed the white half over the wart. i remember doing this every evening for a week or so and they would discard the potato after using both sides and cutting a new white part over again. so does anyone remember the potato for getting rid of planters wart?
