This method worked for me, it removes the wart and the wart does not return.
Every 5 to 8 months, the wart will "bloom", becoming softer and pushing its small black "seeds" to the surface.
These black seeds are the things that cause the wart to spread, and to return.
Completely remove them using a small penknife, a needle or tweezers, get them into a tissue and into the bin immediately.
They should come out very easily, make sure you get them all.
Wash your hands and the wart as soon as you are done.
Once the seeds are gone the wart will reduce itself in time, and eventually the skin will heal itself completely.
This "blooming" only lasts for a couple of days, so be sure to pay attention.
Thanks for the replies :)
It may be possible to bring out the wart before its blooming time (I haven't had a wart in many years so I can't check it for you)
Try soaking the wart (your hand) in hot water until your fingers go all pruney. My thinking is that the wart will think that conditions are good for it to spread, and open up.
When I first had warts I tried pulling them out with a pliers, it was so painful I could not complete even one fully.
Glad I discovered this method though, getting the seeds out is so easy.
