张子和云∶病肿胀既平，当节饮食，忌盐、血、房室，犯禁者，病再作，乃死不救。病痨嗽
忌房室、膏粱，犯者死。子和案云∶一小儿病痢，用车载数十里，就某寺调理，入门而则死。痢
疾，下坠病也。以车载之，药而又下坠也。所谓落井而又下石，安得不死乎！病患远行，不宜以
车载、马驮，病已扰矣，甚者多死不救。一人为犬所啮，大痛不可忍，偏痒燥，自云载至家二十
里，一夕而死。时人皆不知车之误也。扰动则邪气益盛，是以死也。
伤寒之后，忌荤肉、房事，犯之者不救。水肿之后忌油盐。肚脾胃伤者，节饮食。滑泻之后
忌油腻。此数者决不可轻犯也。唐尧臣， 东人，在北吏部当该，缘家富，平素嗜膏粱，数伤脾
胃。时长夏，因过食伤脾作泻而腹满。求予治，以补中气兼消导而悉愈。随即速欲食肉类，食复
伤又胀而泻。子治之，又愈。竟数日断荤，切欲食肉，命家人烹牛肉和酒食之，惟饱闷而烦躁，
求予消导之，不愈。自云数日不大便，恐后闭所致，欲通之。予以屡伤脾胃，元气未复，何敢通？
道不信，别求医通利，不一日口干躁，心烦而死。原病伤食而又犯之，原病下泄，今又犯之，犯
之又犯，其死必矣。
时病新差，食蒜 者，病发必致大困。时病新愈，食犬羊肉者，必作骨蒸热。时病新愈，食
生枣及羊肉，必作脂上热蒸。时病新愈，食生菜，令人颜色终身不平复。病患新愈，饮酒食韭，病必复作。
张子和说：肿胀病消退后，应当节制饮食，忌食盐、动物血液及房事，若违反禁忌，疾病复发，则无法救治。患肺痨咳嗽者，忌房事及肥甘厚味，违反者致死。张子和医案记载：有一个小儿患痢疾，用车载着走了几十里路，去某寺庙调理，刚进门就死了。痢疾是气机下坠的病证，用车载动它，药物又导致气机下坠，这叫做“落井下石”，怎么能不死呢！病患远行，不宜用车载或马驮，因为病情已经受到扰动，严重的往往无法救治。有一人被狗咬伤，疼痛难忍，患处偏侧瘙痒干燥，自述被车载回家二十里，当晚就死了。当时的人都不知道是车运造成的错误。扰动导致邪气更加旺盛，因此死亡。
伤寒病之后，忌食荤腥肉类及房事，违反者无法救治。水肿病之后忌食油、盐。脾胃受损者，需节制饮食。滑泄腹泻之后忌食油腻食物。这几项决不可轻易违反。唐尧臣，山东人，在北方吏部任职，因家境富裕，平时嗜好肥甘厚味，多次损伤脾胃。当时正值长夏，因过食损伤脾胃导致腹泻且腹部胀满。求我治疗，我用补中益气兼消食导滞的方法使他痊愈。随即他急于想吃肉类，进食后再次损伤，又出现腹胀和腹泻。我再次治疗，他又痊愈了。然而几天后断绝荤腥，却极度想吃肉，命令家人烹煮牛肉配酒食用，结果只感到饱闷烦躁，求我消食导滞，无效。自述几天不大便，担心是便秘所致，想要通利大便。我认为他屡伤脾胃，元气未恢复，怎敢用通利之法？他不听劝告，另找医生通利，不到一天出现口干烦躁，心烦而死。原本就是伤食引起的病却又犯忌，原本是下泄的病，现在又犯忌，犯了再犯，其死亡是必然的。
时令病刚刚痊愈，吃大蒜的，疾病发作必定导致身体极度困顿。时令病刚刚痊愈，吃狗肉羊肉的，必定引发骨蒸热（一种自觉骨内发热的症状）。时令病刚刚痊愈，吃生枣及羊肉的，必定引发脂上热蒸（自觉头部或上半身发热如蒸）。时令病刚刚痊愈，吃生菜的，令人面色终身无法平复正常。病患刚刚痊愈，饮酒并吃韭菜的，疾病必定复发。
Zihe said: After the swelling subsides, one should regulate diet, avoid salt, animal blood, and sexual intercourse. Violating these prohibitions will cause the disease to recur, leading to untreatable death. For those suffering from consumption (Lao) with cough, sexual intercourse and rich/greasy foods are prohibited; violators die. Zihe's case record states: A child suffered from dysentery and was transported by cart for dozens of li to a temple for recuperation. He died upon entering the gate. Dysentery is a condition characterized by downward sinking of Qi. Transporting him by cart aggravated this downward movement, while the medicine also promoted downward purging. This is akin to "throwing stones into a well" after someone has fallen in; how could he not die? When patients travel long distances, they should not be carried by cart or horse, as the illness is already disturbed. Severe cases often result in untreatable death. One person was bitten by a dog, experiencing unbearable pain, with localized itching and dryness. He stated he was carted home for twenty li and died that night. People at the time did not realize the error caused by the cart. Disturbance causes pathogenic factors to flourish, leading to death.
After Shanghan (Cold Damage), pork/beef/mutton and sexual intercourse are prohibited; violators cannot be saved. After edema, oil and salt are prohibited. For injuries to the spleen and stomach, diet must be regulated. After slippery diarrhea, greasy foods are prohibited. These few rules must never be lightly violated. Tang Yaochen, a man from Shandong, served in the Ministry of Personnel in the north. Due to his wealth, he usually indulged in rich and greasy foods, frequently injuring his spleen and stomach. During the late summer, excessive eating injured his spleen, causing diarrhea and abdominal fullness. He sought my treatment, and I cured him completely using methods to tonify middle Qi and promote digestion. Immediately after, he urgently desired meat. Eating it again injured him, causing bloating and diarrhea. I treated him again, and he recovered. However, after several days of abstaining from meat, he intensely craved it, ordered his family to cook beef with wine, and ate it. He only felt full, stifled, and irritable. He asked me to promote digestion, but it was ineffective. He stated he had not had a bowel movement for several days and feared constipation, wishing to unblock it. I reasoned that since his spleen and stomach were repeatedly injured and his Yuan Qi (Original Qi) had not yet recovered, how could I dare to use purgatives? He did not believe me and sought another doctor to promote purgation. Within a day, he developed dry mouth, irritability, and heart vexation, then died. The original illness was caused by food stagnation, yet he violated the prohibition again. The original illness involved downward discharge, yet he violated it again. Violating prohibitions repeatedly makes death inevitable.
When seasonal diseases have just resolved, consuming garlic will cause the disease to flare up, leading to severe debility. When seasonal diseases have just resolved, consuming dog or mutton will inevitably trigger bone-steaming fever (a sensation of heat steaming from the bones). When seasonal diseases have just resolved, consuming raw dates and mutton will inevitably trigger upper-body steaming heat. When seasonal diseases have just resolved, consuming raw vegetables will cause the complexion to remain uneven and abnormal for life. When patients have just recovered, consuming alcohol and leeks will inevitably cause the disease to recur.
