That IS interesting. Do they dissolve or what? I used castor oil and baking soda for about 2 months on a large facial mole. Didn't get rid of it completely, and it was very painful, and bled a lot. It did knock it down to where it is almost flat now. I was going to get some black salve on the ones on my back and arms, but I'll the plain castor oil and see what happens.
