Treatment for various types of malaria.
Method: Take one strip of snake skin (She Tui), or three to five strips, calcine them over charcoal fire until the medicinal properties are preserved (Cun Xing), and grind into a fine powder. Administer one "yi zi" (a traditional small unit of weight) per dose, taken with Wugen Shui (water without roots, such as rain or dew water). The medicine should be taken one shichen (two hours) before the onset of symptoms. Avoid consuming chicken, fish, and cold/raw foods. An alternative method is to plug both ears with snake skin and take a small amount of medicine just before the attack.
In ancient times, the Yellow Emperor asked Qibo: "There are many prescriptions for malaria, yet few result in cure. Why is this?" Qibo replied: "Malaria has twelve types." The Emperor asked: "What are the names of these 'malaria ghosts'? May I hear them?" Qibo said: "If you know the name of the malaria ghost, it will be cured; if not, even a hundred prescriptions will fail." The Emperor said: "I wish to hear about them."
