痘疹痊愈后出现大便排脓，是热毒侵入大肠所致。适宜使用四物汤（由当归、川芎、白芍、熟地黄组成的补血基础方）加入黄芩、黄连、枳壳、荆芥穗。或者使用黄连解毒汤（由黄连、黄芩、黄柏、栀子组成的清热泻火方）加入生地黄。
上述痘疹病症自有其专科治疗。因为因其形态表现被冠以外科之名，所以似乎归属于外科范畴。现采集数条以备参考。
固罐法：近来少阳城用罐时，可用双耳茶叶罐代替。将罐子烤热，在罐外遍擦捣碎的大蒜，再烤再擦，如此重复三四次。
接着将姜、醋放入罐内，加热煮至干燥为止。然后用黄土二分、煤灰一分，混合马毛，用盐水调和，以厚度为一指为度，阴干待用。
封罐口法：放入药物完毕后，盖上铁盏，用铁丝捆绑固定。用石膏、无名异（一种矿物药，主要成分为磁铁矿或赤铁矿）各等分，食盐减半，全部研磨成极细粉末，用醋调成膏状。
接着在盏内加两三块炭火，烧烫铁盏，用笔蘸取药膏沿四周涂抹，随干随涂，以与口平齐为标准。
另一种方法是用生石膏、生白矾、食盐三味药，等分为末，用水调匀涂抹，如前所述。
冬至之后，取十斤洁净朴硝，用水一斗五升，五斤打碎的白萝卜，同硝一起放入锅内，煮化。待汤水滚沸充足后，捞出萝卜。将竹丝箕铺上两层绵纸，架在新缸上，将硝汤慢慢倒入箕内，待滤尽后再添，直到汤液滤完为止。将缸放置在露天处，暴露三天。硝结晶在缸边，倒掉剩余水分，沥干为止。取下硝，再用砂锅放在炭炉上，将一碗硝融化煎滚，用铜匙铲搅拌。当即将凝结时，铲入小鱼酢罐内，距罐口上方约一寸处。再下硝炼制。如此完成后，每罐下方，用三个呈“品”字样的钉子钉入土地，留寸半在外面，将罐浮搁在上面，钉头上用瓦片盖住口，周围用段砖砌成百眼炉，围绕离罐一寸半许，将炭安入炉内四周，底火顶火互相保护，等候罐内硝变红为止。次日取出硝来，预先用大绵纸摊在洁净的阴凉土地上，将硝碾细，用绢筛筛在纸上，厚度为一钱浓，不能再多。将门闼都关闭，不许让人看见。三天后，硝自然复活，色白如粉，轻虚成片，用钵盛收，用纸盖好，上面再用乱纸一寸许，以吸收潮气，使其不凝结。此品最能降火化痰，清利脏腑，怪症服用可消除，狂躁服用即愈，搜除百病，安敛心神。况且此服用之不伤元气，只有久病泻痢者不宜。大人每次服用三四钱，小儿五分至一钱皆可，都用白滚汤或葱汤空腹化服。待排便二三次后，随即喝稀粥，自然精神爽健，调和脏腑，津液顿生，百病如失。又取过硝石六两，加朱砂三钱、青黛一钱、冰片一钱五分，共研细末，照前筛在纸上，再用纸盖一层，四边以戒尺压紧，勿令走气。候三天后，取起密收。又名阳春紫雪，最治失心忘志、颠痫健忘、小儿急惊、大人异症。每次服用五分至一钱，都用淡竹叶、灯心汤化服，屡有奇效，不可尽述。玄明粉乃神仙保命服食之品，每一斤加生熟甘草末一两，葱汤化服二三钱，令人容颜悦泽，轻身耐老矣。
Purulent stool after smallpox is caused by heat toxin entering the large intestine. It is appropriate to use Siwu Tang (Four Substances Decoction) plus Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Zhiqiao (Aurantii Fructus), and Jingjiesui (Schizonepetae Spica). Alternatively, Huanglian Jiedu Tang (Coptis Toxin-Resolving Decoction) plus Shengdi (Rehmanniae Radix) can be used.
The above smallpox conditions naturally have their own specialized field. Because their manifestations bear the name of external medicine (waike), they also seem to belong to external medicine. Several entries are recorded here for reference.
Method for Reinforcing the Jar: Recently, the Shaoyangcheng jar is used, which can be substituted with a double-handled tea leaf jar. Heat the jar, pound garlic, and rub it all over the outside of the jar. Heat it again and rub again. Repeat this three or four times.
Then, put ginger and vinegar into the jar, warm it, and boil it until dry. Next, use two parts of yellow earth, one part of coal ash, mixed with horse hair, and blend with salt water. Apply the mixture to reinforce the jar to a thickness of one finger's width. Let it dry in the shade for later use.
Method for Sealing the Jar Mouth: After adding the medicinal ingredients, cover with an iron lid and secure it with iron wire. Take equal parts of Gypsum Fibrosum (Shigao) and Pyrolusite (Wumingyi), with half the amount of salt (Yan). Calcine all of them and grind into extremely fine powder. Mix with vinegar to form a paste.
Then, place two or three pieces of charcoal inside the lid, heat the lid, and use a brush to dip the medicinal paste and apply it all around the joint. Apply more as it dries, until the surface is level.
Another method: Use equal parts of raw Gypsum Fibrosum (Sheng Shigao), raw Alumen (Sheng Baifan), and salt (Yan). Grind into powder, mix with water, and apply as before.
After the winter solstice, take ten jin of clean Mirabilitum Praeparatum (Poxiao). Use one dou and five sheng of water, and five jin of white radish, crushed. Put the nitre and radish into a pot and boil until dissolved. When the decoction has boiled sufficiently, remove the radish. Use a bamboo sieve, spread two layers of tissue paper inside the sieve, and place it over a new vat. Slowly pour the nitre decoction into the sieve. Wait for it to filter through and add more, until all the liquid has filtered through. Place the vat in the courtyard, expose it to the open air for three days. The nitre will crystallize on the sides of the vat. Pour off the remaining water and let it drain completely. Remove the nitre. Then, use an earthenware pot placed on a charcoal stove. Take one bowl of the nitre, melt it, and bring to a boil. Stir with a copper spoon. When it is about to congeal, scoop it into small fish sauce jars, leaving about one cun of space from the top. Continue refining more nitre in the same way. After this is complete, for each jar, use three nails driven into the ground in a triangular pattern, leaving one and a half cun exposed. Float the jar on top of the nails. Cover the mouth with a tile. Surround the jar with broken bricks to build a perforated furnace, leaving about one and a half cun of space around the jar. Place burning charcoal into the furnace all around, ensuring both bottom fire and top fire are maintained. Heat until the nitre inside the jar turns red. The next day, take out the nitre. First, spread large sheets of tissue paper on clean, shaded ground. Grind the nitre finely, sift it through a silk sieve onto the paper to a thickness of one qian, no more. Close all doors and windows, and do not allow anyone to see it. After three days, the nitre will naturally revive, becoming white like powder, light and forming flakes. Store it in a bowl, covered with paper. Place another layer of scrap paper about one cun thick on top to absorb moisture, preventing clumping. This product is most effective for descending fire and resolving phlegm, clearing and regulating the zang-fu organs. Strange diseases can be eliminated by taking it; mania and agitation are cured upon use. It searches out and eliminates hundreds of diseases, calming and收敛 the heart spirit. Moreover, taking it does not damage the original qi. Only those with chronic diarrhea or dysentery should not take it. Adults take three to four qian each time; children can take from five fen to one qian. Take it on an empty stomach, dissolved in plain boiled water or scallion decoction. After two or three bowel movements, drink thin porridge. One will naturally feel refreshed and vigorous in spirit, with harmonized zang-fu organs, immediate generation of body fluids, and all diseases as if lost. Another method: Take six liang of calcined Nitrum (Xiaoshi), add three qian of Cinnabaris (Zhusha), one qian of Indigo Naturalis (Qingdai), and one qian and five fen of Borneolum Syntheticum (Bingpian). Grind together into fine powder. Sift onto paper as before, then cover with another layer of paper. Press the edges tightly with a ruler to prevent air leakage. After more than three days, collect it and store it securely. It is also called Yangchun Zixue (Spring Purple Snow). It is most effective for treating loss of mind and forgetfulness, epilepsy and amnesia, infantile acute convulsions in children, and strange diseases in adults. Take five fen to one qian each time, dissolved in decoction of Lophatheri Herba (Danzhuye) and Juncus Medulla (Dengxin). It has repeatedly shown remarkable efficacy, which cannot be fully described. Xuanmingfen (Refined Mirabilitum) is what immortals take to preserve life. For every one jin, add one liang of powder from raw and prepared Glycyrrhizae Radix et Rhizoma (Gancao). Take two to three qian dissolved in scallion decoction. It makes one's complexion radiant and beautiful, lightens the body, and delays aging.
