愈后大便久不行，作呕不进食，此下格病也。宜调胃承气热服，下宿结而呕止。
愈后数日，腹痛里急，此下焦伏邪，欲作滞下也，宜芍药汤∶白芍、当归、浓
朴（各一钱）、槟榔（二钱）、甘草（七分）。
愈后大便数日不行，别无他证，此虚燥也。切不可攻，宜蜜导法，甚则宜六成
汤∶当归（一钱半）、白芍、麦冬、天冬、（各一钱。）地黄（五钱）、肉苁蓉（三钱）、日后更燥，宜六味
丸减泽泻。
愈后五更夜半作泻，其脉迟细而弱，此命门阳虚也，宜七成汤∶故纸（三钱）、炮附、
白茯苓、人参、（各一钱。）五味（八分）、甘草（五分）。愈后更发者，八味丸倍加附子。
愈后微渴微热，不思饮食，此正气虚也，强与之即为食复，渐进稀粥，以复
胃气。
愈后能饮食，肢体浮肿，此气复也。胃气大健则浮肿消，勿误为水气。若小便
不利而肿，乃是水肿，宜济生肾气丸。
愈后因劳而复发热，宜安神养血汤∶茯神、枣仁、白芍药、当归、远志、桔梗、
地黄、陈皮、甘草、圆眼肉。
愈后伤食，吞酸嗳气而复热，轻则少食，重则消导，自愈。若无故自复，此前
邪未尽除也，稍与前证所服之药，以彻其余邪自愈。
经水适来而瘟，邪不入胃，入于血室，至夜发热谵语，或止夜热而不谵语，宜
柴胡汤∶柴胡、黄芩、半夏、甘草、生地。
经水适断而瘟，宜柴胡养荣汤，与适来有虚实之别。
妊娠瘟病，宜下者，照前法下之，毋惑参术安胎之说而用补药，则大凶矣。但
下药得下则已，勿过剂也。
小儿瘟病，遇时气盛行，发热、目吊、惊搐、发痉，是也。宜太极丸∶天竺黄、
胆星、（各五钱。）大黄（三钱）、麝香（三分）、冰片（三分）、僵蚕（三钱），糯米饭丸，如芡实大，朱砂为
衣。凡遇疫证，姜汤下一丸，神效。
病后大便长期不通，伴有呕吐、无法进食，这是“下格”病。适宜热服调胃承气汤，以攻下积滞的燥结，呕吐即可停止。
病后数日，出现腹痛且肛门急迫感，这是下焦潜伏的病邪，想要发展为痢疾（滞下）。适宜使用芍药汤：白芍、当归、厚朴（各一钱）、槟榔（二钱）、甘草（七分）。
病后大便数日不行，但没有其他症状，这是虚性燥结。千万不可使用攻下法，适宜用蜜导法（蜂蜜栓剂塞肛），如果情况严重，适宜使用六成汤：当归（一钱半）、白芍、麦冬、天冬（各一钱）、地黄（五钱）、肉苁蓉（三钱）。日后如果更加干燥，适宜使用六味丸减去泽泻。
病后在五更或夜半时分发生腹泻，脉象迟细而弱，这是命门火衰（肾阳虚）。适宜使用七成汤：补骨脂（故纸，三钱）、炮附子、白茯苓、人参（各一钱）、五味子（八分）、甘草（五分）。病后再次发作的，使用八味丸并加倍增加附子的用量。
病后有轻微口渴和发热，不想吃东西，这是正气虚弱。强行喂食就会导致“食复”（因饮食不当导致的复发），应逐渐进服稀粥，以恢复胃气。
病后能够进食，但肢体浮肿，这是阳气恢复的表现。胃气大大强健则浮肿消退，不要误认为是水气病。如果小便不利并且浮肿，那才是水肿病，适宜使用济生肾气丸。
病后因劳累而再次发热，适宜使用安神养血汤：茯神、酸枣仁、白芍药、当归、远志、桔梗、地黄、陈皮、甘草、桂圆肉。
病后饮食不节导致伤食，出现吞酸、嗳气并再次发热，轻症减少饮食，重症使用消食导滞法，即可自愈。如果是无故自行复发，这是因为之前的病邪没有完全清除，稍许给予之前病症所服的药物，以清除残余病邪即可自愈。
月经刚来潮时感染瘟疫，病邪不进入胃，而是进入血室（子宫及相关血脉），到了夜间出现发热和胡言乱语，或者只是夜间发热而不胡言乱语，适宜使用柴胡汤：柴胡、黄芩、半夏、甘草、生地。
月经刚结束时感染瘟疫，适宜使用柴胡养荣汤，这与经水适来时的病情有虚实之别。
妊娠期患瘟疫病，需要攻下的，按照前面的方法攻下，不要被“参术安胎”的说法迷惑而使用补药，否则会有大凶险。但是攻下药只要达到通便效果就停止，不要过量。
小儿患瘟疫病，遇到时行疫气盛行，出现发热、眼睛上吊、惊厥抽搐、发痉等症状，就是这种情况。适宜使用太极丸：天竺黄、胆南星（各五钱）、大黄（三钱）、麝香（三分）、冰片（三分）、僵蚕（三钱），用糯米饭做丸，大小如芡实，朱砂为衣。凡是遇到疫病证候，用姜汤送服一丸，效果神奇。
After the recovery from illness, if bowel movements have been absent for a long time, accompanied by vomiting and inability to eat, this is "Xiage" (Lower Obstruction). It is appropriate to take Tiaowei Chengqi Tang (Regulate the Stomach and Purge the Yang Decoction) while hot, to purge accumulated dryness and stop the vomiting.
A few days after recovery, if abdominal pain and tenesmus occur, this indicates latent pathogenic factors in the Lower Jiao (Lower Burner), intending to develop into dysentery ("Zhixia"). It is appropriate to use Shaoyao Tang (Peony Decoction): Baishao (White Peony Root), Danggui (Angelica Sinensis), Houpo (Magnolia Bark) (each 1 qian), Binglang (Areca Seed) (2 qian), Gancao (Licorice Root) (7 fen).
If bowel movements are absent for several days after recovery, without other symptoms, this is deficiency-type dryness. One must absolutely not use purgatives; it is appropriate to use the Honey Suppository method. If severe, Chengliu Tang (Six-Tenths Decoction) is appropriate: Danggui (Angelica Sinensis) (1.5 qian), Baishao (White Peony Root), Maidong (Ophiopogon Tuber), Tiandong (Asparagus Tuber) (each 1 qian), Dihuang (Rehmannia Root) (5 qian), Rousongrong (Cistanche Stem) (3 qian). If dryness worsens later, Liuwei Wan (Six-Ingredient Pill with Rehmannia) minus Zexie (Alisma Rhizome) is appropriate.
If diarrhea occurs at dawn or midnight after recovery, with a slow, fine, and weak pulse, this is Mingmen Yang Deficiency (Deficiency of Kidney Yang). It is appropriate to use Chengqi Tang (Seven-Tenths Decoction): Guzhi (Psoralea Fruit), Paofu (Prepared Aconite Root), Bai Fuling (Poria), Renshen (Ginseng Root) (each 1 qian), Wuwei (Schisandra Berry) (8 fen), Gancao (Licorice Root) (5 fen). For recurrences after recovery, Bawei Wan (Eight-Ingredient Pill) with doubled Fuzi (Prepared Aconite Root) is appropriate.
If there is slight thirst and fever after recovery, along with loss of appetite, this is deficiency of Righteous Qi (Vital Energy). Forcing food intake will lead to "Shifu" (Relapse due to Diet); one should gradually consume thin rice gruel to restore Stomach Qi.
If the patient can eat after recovery but exhibits limb edema, this indicates the restoration of Yang Qi. When Stomach Qi becomes robust, the edema will subside; do not mistakenly diagnose this as Water-Qi pathology. If urination is difficult and edema is present, it is Edema Disease, and Jisheng Shenqi Wan (Jisheng Kidney Qi Pill) is appropriate.
If fever recurs after recovery due to overexertion, Anshen Yangxue Tang (Calming the Spirit and Nourishing Blood Decoction) is appropriate: Fushen (Poria with Hostwood), Zaoren (Sour Jujube Seed), Baishao (White Peony Root), Danggui (Angelica Sinensis), Yuanzhi (Polygala Root), Jiegeng (Platycodon Root), Dihuang (Rehmannia Root), Chenpi (Tangerine Peel), Gancao (Licorice Root), Yuanyanrou (Longan Aril).
If food stagnation occurs after recovery, causing acid regurgitation, belching, and recurrent fever, mild cases require dietary restriction, while severe cases require digestion-promoting methods, leading to spontaneous recovery. If recurrence happens without cause, it is because previous pathogens were not fully eliminated; administering a small amount of the medicine used for previous symptoms will clear residual pathogens and lead to recovery.
When menstruation has just begun and plague infection occurs, the pathogen does not enter the Stomach but enters the Blood Chamber (Uterus and related blood vessels). Fever and delirium occur at night, or only night fever without delirium. Chaihu Tang (Bupleurum Decoction) is appropriate: Chaihu (Bupleurum Root), Huangqin (Scutellaria Root), Banxia (Pinellia Tuber), Gancao (Licorice Root), Shengdi (Raw Rehmannia Root).
When menstruation has just ended and plague infection occurs, Chaihu Yangrong Tang (Bupleurum and Ying-Nourishing Decoction) is appropriate, which differs from the case of menstruation beginning in terms of excess and deficiency.
For pregnant women suffering from plague, if purgation is indicated, follow the previous methods for purgation. Do not be confused by theories regarding "Renshen and Baizhu for fetal security" and use tonifying medicines, as this would be extremely dangerous. However, stop using purgatives once bowel movement is achieved; do not overdose.
For children suffering from plague during an epidemic, presenting with fever, eyes rolling upward, convulsions, and spasms, this is the condition. Taiji Wan (Taiji Pill) is appropriate: Tianzhuhuang (Calculus Bovis), Danning (Arisaema with Betel Nut Juice) (each 5 qian), Dahuang (Rhubarb Root), Shexiang (Musk), Bingpian (Borneol), Jiangcan (Bombyx Batryticatus) (each 3 qian). Make pills with glutinous rice paste, size similar to Euryale Seed, coated with Zhusha (Cinnabar). For any epidemic syndrome, administer one pill with Ginger Decoction; the effect is miraculous.
