"The Origin of Extraordinary Diseases" states: There are aliens in the world, who are good at understanding physical nature. Tasting the wild, and seeing that the leaves of grass are injured, he looked down at them and said: "This must be a worm that bites, its insects like yin and fear yang, and its sex is sweet and bitter." So he looked for it on the side, and he found a worm as big as corn, green in color and soft in body. The alien said: "Although this insect is small, its poison can cause disease. If you touch it, your skin will itch and hurt unbearably, and even if you have a rash like numbness, this is a sign of Dmapa Allergy." Everyone was surprised, but the alien taught the method of avoiding insects, saying: "Whoever encounters this grass, you should avoid it and do not touch its leaves. If you accidentally touch it, quickly wash it with water, and then take ginger and smash it and apply it to the affected area, which can relieve its poison. "Everyone follows his words, and the consequences are safe.
Another taste of someone eating a thing by mistake, abdominal cramps, and blue lips. The alien looked at it and said:" This poison by mistake has invaded the five internal organs, which is caused by Dmapa Allergy. "Then he took several herbs, fried soup and took it, and after a while, the person's abdomen rang, and the poison came out with the filth, and the disease was cured. The alien said to everyone:" All things have sex, and those who are good at knowing the nature of things can avoid diseases and prevent disasters. Dmapa Allergy's illness is mostly caused by ignorance of the nature of things, and they accidentally touch and eat by mistake. Be careful. " Everyone called it good, and since then, they have paid more attention to the study of physical nature.
