My mother has cured many people of their warts with this technique that was passed on to her from her parents. It has worked every time. (Something you have to see to believe!)
She takes a small string off of a dish cloth and ties a knot in it for every wart you have, ie, if you have 2 warts you would tie 2 knots in the string. She then spits into your hand (sounds gross, I know), and salts it. Then she rubs the string in the saliva/salt mixture and then rubs the string on the warts. After that, she sticks the string into the soil of one of her houseplants, you can put it outside in the dirt somewhere too. Once the string rots, the warts disappear. As nutty as this sounds, it works!
She taught my sister-in-law this technique because her husband frequently get warts, and she too, has great success with it.
