I don't know anything about that product, but I do know how to remove warts naturally!
I had a couple of warts on my hand when I was a child. My mother heard about an old natural remedy and wanted to try it. She took a potato and sliced it, just a thin slice so that the potato juice was there. She had me rub the potato on my warts several times a day and let it dry on my hand. She stored it in a container in the fridge and when it was time to do it again we'd slice another slice off and do it again.
This was too many years ago for me to remember just how long it took for the warts to be gone but they disappeared! I'm thinking it was just a couple of weeks because you know when you're a child and you have to do something you don't want to do, how long it would seem like it was taking? I never had that 'will this ever be done' question, I'd remember if I did, so that means it didn't take long and the warts have never come back.
I don't know if potatoes are the same today as they were when I was a child but I'd say like everything else they're much more toxic. If I was going to use that method again I'd be sure I used an organic potato.
