To cure corns, crush a comfrey leaf in your hand until it becomes moist, and then place it over the corn and cover with an old sock. Do this right before bedtime, either outside or near a window where you can see the Moon. In a few days time, the corn will leave your body. For extra healing, while you are rubbing the comfrey leaf over the corn and watching the Moon, repeat this phrase:

What I see is growing, What I rub is going.

As soon as possible after you wake in the morning, bury the crushed comfrey leaf. The leaf will deteriorate into the earth as the corn diminishes.
