Do some looking on the castor oil forum. I posted on there about how I removed a mole with castor oil. I just applied a wee drop two or three times a day and it shrank right up. It didn't go totally away, maybe because I got kind of lazy about keeping it up when the weather got cold and it was covered. But it's much smaller and pale, more like a little freckle now instead of a big freaky looking mole.
