I used Epson Salt to clean my wounds on my toenail
after I bumped it on the door. My nail was flipped over, and bleeding. I mixed the salt with warm water; not too hot, enough to avoid skin burn, and soaked it for 15 minutes every time, twice a day.
I applied antibiotic and pain relief cream over it after it air dried, then bandaged. My nail was removed naturally in five days without pain. I am waiting for my nail to be full grown. Happy ending.
