A heat pack can be used to treat an ear infection and one natural remedy uses warmed salts. Use sea salt, organic if possible, and warm the salt in a pan. Pour it into a cotton pouch. Use a sock that’s made from all natural and un-dyed cotton. Place the pack on the infected ear to relieve pain. Don’t try it with table salt since it will spill and don’t use the salt after its been heated. The heat pack can be warmed up again as needed.
