1. Knead with honey

Wash your hands and dry them after breakfast every day. Apply honey to the fingernails of your palms and rub them with a small towel for 5- 10 minutes to keep your hands warm. Wash your hands before going to bed at night, and then rub your hands with honey according to the above method.

Choose a ripe banana with black skin, bake it by the fire, apply it to the affected area and knead it for a while.
