It’s very simple – first, you need to crush the 10 tablets of aspirin (300 mg), and make them like powder. Then, you need to mix the powder with 250 ml of brandy (or 70% medical alcohol) and leave it for 1-2 days. Note: make sure you shake this mixture every night and you need to dip one piece of folded gauze in it. Put the gauze soaked in this mixture on your heel (calluses, foot), wrap your foot with a nylon bag and put on your socks.
