Letting adhesive bandage stay on a cut for days

When you put antibacterial ointment on a cut, keeping it for days will increase the moisture on the cut. After a day, remove the bandage and let it heal on its own. If the cut is deep, change adhesive bandage twice a day. Make sure the entire area is clean and dry.

Heat on a sprain or fracture

Butter on a burn

Putting butter on a burn is a blunder. It is greasy and keeps heat within to make healing difficult. Instead run cold water over the burn to ease the pain. Keep the affected area loosely covered so that it dries.
