Children in rural areas have been frostbitten before. What remedies have you used?

When I was a child, my hands were basically split, deep and big. Boys, girls and children should always rub some hand oil. I'm a little scared to think about the pain in my hand. My hometown is in the countryside, and there is no magic frostbite medicine. This is an indigenous method passed down from mouth to mouth. One of the most common methods is to boil eggplant seedlings in water and soak them for a long time. Although this method is not effective, it is really useful! If frostbite is severe, use pepper seedlings. This thing is more painful. If there are cracks in your hands or feet, it hurts too much. That's how I survived frostbite when I was a child. Every frostbite is like the last execution ground. Up to now, I haven't figured out what role pepper seedlings play. Fortunately, when I was a child, I was stocky and came over in a daze. It's not too cold now, and the radiator is hot now. Nowadays, few children get frostbite because of the cold weather, and all kinds of frostbite drugs in pharmacies give people more choices. Past therapies are rarely used now. ?
