My daughter sunburned the shins on both legs. They had 3rd-degree burns. Big yellow blisters. She could walk for about 3 days. I was told by an elderly man to soak gauze in Castor Oil and wrap her legs with the gauze and leave it for 3 days. The next day my daughter was able to walk. The 3rd day I removed the gauze and she was healed. Blisters gone. Her legs we just a shade pink. It left no scars. Awesome stuff.
