Take seven plum blossom stamens, grind them into a paste, combine with one qian of Cinnabar (Zhu Sha, 朱砂) processed by water flotation to an extremely fine powder, and take it mixed with rock sugar on New Year's Eve. The smallpox eruption will inevitably be sparse; if another dose is taken, the smallpox may not erupt at all.
Earthworm (Dilong, 地龙), specifically one slender, bright red, active specimen with a white neck, is preferred. One black-bone chicken egg. Make a small hole in the eggshell, insert the earthworm inside, seal the hole with paper containing skin, and steam it over rice until cooked. Remove the earthworm and feed the egg to the child. Eating one such egg every year on the Day of Li Chun (Start of Spring) ensures lifelong immunity from smallpox. During outbreaks of smallpox, consuming one or two eggs is highly effective. It can also be consumed on the Day of Chun Fen (Spring Equinox).
Select a plump male rat, remove fur, skin, and internal organs. Boil it thoroughly with Amomum fruit (Sharen, 砂仁) and salt, then eat it. This results in sparse smallpox eruptions. Feeding this before the consumption of meat is particularly effective.
Choose a crucian carp of any size, remove scales and intestines, but do not wash with water. Finely chop Coriander (Yanxi, 芫su), mix with a little salt, stuff it into the fish belly, wrap the fish in grass hearts, and bake/roast it in fire. Feed it to the child gradually. This effectively dilutes and resolves smallpox toxin. Bury the scales, intestines, bones, and spines.
In August, collect a large toad, remove the scalp and bones. Use the clean meat, flower salt, and sesame oil to roast/cook it in a pan and consume it. Consuming more than ten toads is even better and can prevent the risk of smallpox and rashes.
Cicada slough (Chantui, 蝉蜕), Phoenix Slough (Fenghuang Tui, i.e., hatched eggshells), and Immortal Slough (Shenxian Tui, i.e., parents' fingernails/clippings). Take equal parts of these four ingredients, dry-roast them, and grind into a fine powder. Take one qian per dose, form honey pills the size of mung beans, and take them on New Year's Eve each year. After three years, smallpox will never erupt.
Raise a single yellow female chick separately, ensuring it does not mix with roosters. Collect seven large raw eggs, mark them sequentially for storage, avoid writing characters on them, and protect them from mosquitoes. Buy seven small bamboo baskets to hold them. Tie strings to thin bamboo sticks as markers corresponding to the number of eggs. Soak the eggs in an eastern toilet that no women enter. On the first day of the twelfth lunar month, soak the first egg; on the second day, soak the second egg; from the third to the seventh day, soak one egg each day according to the date. By the eighth day, check the bamboo stick markers. Retrieve the previously soaked eggs one by one daily according to the count. Cook them in a clay pot and eat them on an empty stomach. This ensures a life free from disease and robust health, with effects beyond description.
