It has been shown that warts are somehow responsive to suggestion, which explains why children especially have success with selling their warts, or other magical ways of getting rid of them. If they believe they will go, they very often do.
Even though I had read that, it is hard to believe enough to actually get them to go.
This is my story, strange as it may sound; I started out with one tiny flat wart on the pad of my thumb about the size of a brown rice grain. It was there for about three years, and never did me any harm, or got bigger. It was not unsightly or embarrassing, and I didn't worry too much about it. Then others started coming. (This is three years later, remember) Soon they were all over my hands, in visible spots. They were big. A couple were huge. They would bleed if I tried to mess with them. I was embarrased to show my hands. I tried vinegar, garlic, wart kill from the chemist, banana skins, all kinds of things. I successfully ripped one or two of the bigger ones out completely (with a lot of blood) but they would grow back usually. Or more would spring up on adjacent fingers. In all this time, the original one on my thumb stayed exactly as it was, no bigger no smaller. Still flat and unobtrusive, unlike many of the other ones.
I made a deal with this wart. I said to it, Look I know you have some juristiction here, you were here first. You are in charge of all these other hooligans. I am about to reeeally get nasty with them (and start the wart kill stuff again, which was casustic and painful but had the most success) but I will leave you alone completely if you tell them all its time to go. I put the stuff on the two biggest, and if this makes sense, with intention. Also with no intention to harm what I now called to myself the King wart. Most of the other warts were too small to put the stuff on without getting it on my skin as well. But, they all went. All within a few weeks. Except the King Wart. This all happened about a year ago now, and I have just looked down as I was typing this, and even my original wart has somehow dissappeared in the last few weeks without me even noticing. I think I will kind of miss it.
