Manganese nitrate 100 grams, very cheap, or buy about 1, 2 yuan will be enough, tape 1 roll.

Method of use:

Manganite little, crushed, put in a bowl with a small amount of water (cool water), so that it is crystallized spare. Cover the top to fix it, and change the medicine once a day or every other day until the corns disappear.

This method has cured me of 2 small corns on my fingers and 1 large corns on my toes. It's a good idea to use the medication 10 times to cure it, and it hasn't come back. The eye doesn't even need to go to the hospital to remove, I used to use that garbage corns cream simply does not work, just the corns outside the keratinized layer to remove it, the root of the corns are not removed or will recur.
