Tea tree oil, but I have used organic apple cider vinegar which is great for warts and moles. I soak a cotton ball and tape it on overnight for a few nights.
These are all really good suggestions for wart removal. Applying peroxide daily can do the same as the tea tree oil or apple cider vinegar (or even white vinegar for that matter). My niece used the duct tape method and it worked great.
I've read recently about painless remedies. They include: vitamin E oil, coconut oil, castor oil, washing soda, baking soda, iodine, and dandelion milk. Currently I'm playing around with a combination of these things, but mostly focusing on the iodine. My wart is very stubborn and has resisted all other forms of treatment so far. I'm really hoping this current experiment will work. I'll let you know if it does. So far the only down side is that both the dandelion and the iodine leave a stain on the area for a few days.
I actually had one before, what I did I went to a doctor and got it frozen off. Its gone but it left a scar.
Yep, freezing is quite often the fastest and most effective method. The problem is that some warts are in places that are too sensitive for freezing. I've had the one on my finger frozen twice, and it hurt so bad my whole hand looked like a "claw" for a couple of days because the freezing hit a nerve that radiated pain through all of my fingers. And the wart survived both treatments. However I've had lots of them on my knee and a nasty one on the bottom of my foot, and they all came off with one treatment of liquid nitrogen, and it was barely painful. So it really depends on the wart and where it's positioned.
