I'll tell you another folk prescription. A relative of my family used it, and the effect was good:
Use an aloe vera (the variety should be called "Dragon Claw", there are several kinds of aloe vera, and the leaves of this aloe vera have thorns on both sides). The longer it grows, the better the healing effect. Take a big leaf more than six inches long from aloe, break it off and wash it, cut it into pieces with a knife, then cut a green apple into small pieces, put it in a casserole, and put Tonga in a pot. Put half a spoonful of lard (that is, the oil refined from pig fat) in it, and then put the casserole on the fire to cook. Just cook the soup until the apples are rotten. After cooking, even the apples and aloe in the soup were eaten. However, it is ok to eat aloe raw, but it is not delicious when cooked with apples. There is lard in it, which is even worse. It gives people a feeling that it is difficult to swallow, which is beyond the eating ability of ordinary people.
Another recipe is to eat an egg fried in pig oil every morning, but nothing is put in the egg, including salt. This is also very bad, because it has no taste.
