Warts and all. It gets pretty graphic on the Mudcat at times, don't it?
The trouble with plantar warts is they are all flat and you can't get a grip on them and yank them off root and all, which seems to get rid of them.
Otherwise a spot of blood from the wart on half a potato buried when the moon is waning is supposed to do the job. But I'm no expert on that. A friendly witch is what you need. We've got a few of them round the Mudcat.
