天麻子（三十粒，去壳衣，挑选肥大的），朱砂（一钱，挑选明透的），麝香（五厘，挑选真品且气味纯正的）。先将朱砂和麝香研磨成极细的粉末，然后加入天麻子，共同研磨成膏状。在五月五日午时，涂抹于小后心、两手心、两足心、两脚弯（腘窝）、两胁，共十三处部位，都要涂抹到，不可遗漏。涂药后有剩余的药膏，涂完后不可清洗或触动，听其自然脱落。当年擦过一次，出痘的数量很少；次年端午节再擦三次；再次年端午节再擦一次。这样可以永远不出天花。如果未满周岁的婴儿，在七月七日、九月九日，按照此法涂抹效果更好。男女治疗方法相同。传授此方的人家，三代人都不出天花。
另外，凡是婴儿不论男女，选用川楝子（挑选肥大光洁的）放入盆中捣烂。（一岁至三岁用七个川楝子配三碗水，四五岁用九个配五碗水，六七岁用十五个配七碗水，八岁至十岁用二十个配九碗水，十一岁至十五岁用三十个配十五碗水。）用新砂锅煎煮至浓稠，倒入盆内。在避风处，用一块新的白布蘸取药液，从头到脚遍身洗擦，不留空隙。然后将布擦干，在避风处停留片刻。捣药时忌用铁器。不仅不会出痘，还能避免疮疖。洗浴日期必须选择“除日”中的第七个日子，洗七次。如从五月到八月初止，其中有几个除日，都在热天。
凡是被房事、月经、生产等秽气所犯，用烧大枣产生的烟来化解。如果预防发痒，用桦皮和大枣一起烧烟来化解。被这些秽气侵犯的人，用葛根和茵陈蒿烧烟来化解。被五辛气味侵犯的，用生姜烧烟来化解。被死尸气味及疫疠之气侵犯的，用大黄和苍术烧烟来化解。被狐臭、狗羊气味侵犯的，则烧枫树叶来化解。如果遇到风雨天气，则烧苍术和枫树叶来化解。如果是血少而痘浆难成的情况，则忌烧苍术，因为恐怕更加燥烈导致痘浆更难形成。如果遇到各种恶气，则以乳香熏之，用胡荽酒喷洒。民间有煮醋熏痘的做法，认为醋能活血，殊不知醋具有收敛作用，非常不适宜。
Tianmaizi (Gastrodiae Rhizoma, 30 grains, shell and skin removed, selecting plump ones), Zhusha (Cinnabar, 1 qian, selecting transparent and bright ones), Shexiang (Musk, 5 li, selecting authentic with pure odor). First, grind Zhusha and Shexiang into an extremely fine powder. Then add Tianmaizi and grind them together into a paste. On the noon of the fifth day of the fifth lunar month, apply the paste to thirteen locations: the lower back heart area, both palms, both soles, both popliteal fossae (knee pits), and both flanks. Ensure all areas are covered without omission. Any remaining paste should not be washed off or touched after application; let it fall off naturally. Applying once in the current year results in few pustules. Apply three times again on the Dragon Boat Festival of the following year, and once more on the Dragon Boat Festival of the second subsequent year. This ensures permanent immunity from smallpox. For infants under one year old, applying according to this method on the seventh day of the seventh lunar month and the ninth day of the ninth lunar month is even better. The treatment method is the same for both males and females. The family transmitting this prescription has had three generations free from smallpox.
Furthermore, for any infant regardless of gender, select Chuanlianzi (Toosendan Fructus, choosing plump and smooth ones) and pound them in a basin. (For ages one to three, use seven fruits with three bowls of water; for four to five years, nine fruits with five bowls of water; for six to seven years, fifteen fruits with seven bowls of water; for eight to ten years, twenty fruits with nine bowls of water; for eleven to fifteen years, thirty fruits with fifteen bowls of water.) Decoct in a new clay pot until thick, then pour into a basin. In a wind-sheltered place, dip a piece of new white cloth into the liquid and wipe the entire body from head to foot, leaving no gaps. Then dry the cloth and stay in a wind-sheltered place for a moment. Avoid using iron tools when pounding the herbs. This not only prevents smallpox but also avoids sores and boils. The bathing date must be chosen as the seventh "Chu" day (a day designated for removal/cleansing in the traditional calendar), and wash seven times. From May to early August, there are several such days, all occurring during hot weather.
If contaminated by filth from sexual intercourse, menstruation, or childbirth, resolve it by burning dates to produce smoke. To prevent itching, resolve it by burning birch bark mixed with dates to produce smoke. For those affected by these filths, resolve it by burning Gegen (Puerariae Radix) and Yinchenshao (Artemisiae Scopariae Herba) to produce smoke. If affected by the qi of the Five Pungent Spices, resolve it by burning Shengjiang (Zingiberis Rhizoma Recens) to produce smoke. If affected by the qi of corpses or epidemic pathogens, resolve it by burning Dahuang (Rhei Radix et Rhizoma) and Cangzhu (Atractylodis Rhizoma) to produce smoke. If affected by fox odor or dog/sheep odor, resolve it by burning Fengshuye (Maple Leaf) to produce smoke. If encountering windy or rainy weather, burn Cangzhu and Fengshuye to resolve it. If the blood is deficient and the pus formation of pustules is difficult, avoid burning Cangzhu, lest it increase dryness and make pus formation even more difficult. If encountering various evil airs, fumigate with Ruxiang (Olibanum) and spray with Hucui Jiu (Coriander Wine). Folk practice involves boiling vinegar to fumigate pustules, believing vinegar promotes blood circulation; however, vinegar actually has an astringent effect, which is highly inappropriate.
