《素问》说：热病刚刚痊愈，却时常有余热遗留的情况，这是为什么呢？岐伯回答说：凡是余热遗留的病症，都是因为体内热势尚盛时强行进食所致。像这种情况，都是疾病虽然已经衰退，但热邪仍然潜伏在体内，因为食物进入体内产生的谷气与残留的热邪相互搏结，两股热势合在一起，所以导致余热遗留。治疗这种余热遗留该怎么办呢？回答说：要观察患者体质的虚实，调理气机的逆乱或顺从，这样就可以使疾病必定痊愈。
《素问》又说：患热病时应当如何禁忌饮食呢？岐伯回答说：热病症状稍微减轻时，如果吃肉就会复发（食复），吃得过多就会留下余热（遗）。这就是需要禁忌的原因。
张仲景又说：伤寒病初愈后，再次出现发热，用小柴胡汤主治。脉象浮的，用发汗法解除表邪；脉象沉实的（“实”一作“紧”），用泻下法解除里邪。常器之说：发汗宜用柴胡桂枝汤，泻下宜用调胃承气汤。
张仲景又说：大病初愈后，腰部以下有水气停留者，用牡蛎泽泻散主治。
张仲景又说：大病初愈后，喜欢吐唾沫，久久不能止息，这是因为胸中有寒邪，应用丸药温补中焦，适宜用理中丸。
张仲景又说：伤寒病解之后，身体虚弱消瘦、气息短少，气机上逆想要呕吐，用竹叶石膏汤主治。
张仲景又说：患者的脉象已经平和（“脉”一作“热”），但在傍晚时分感到轻微烦闷，这是因为病刚痊愈，人们勉强给病人进食，脾胃之气还很虚弱，不能消化食物，所以导致轻微烦闷。减少饮食量就会痊愈。
华佗（字元化）说：时令病初愈后，酒、肉、五辛（葱、蒜、韭、薤、兴渠）、油面、生冷、酸滑食物以及房事都要禁止。这是大概的原则。
孙思邈（号真人）说：凡是热病刚痊愈，以及大病之后，吃了猪肉、羊肉、血制品、肥鱼、油腻等食物，一定会导致严重腹泻，这是医生难以治疗的，必然会导致死亡。如果吃饼饵、粱黍、饴糖、肉干、生鱼片、烤肉、枣栗等各种水果和干果，以及坚硬难消化的食物，由于胃气还虚弱，不能消化，必然会再次郁结产生热邪。如果用药物攻下，则会导致胃气虚冷，大便失禁无法控制；如果不攻下则会死亡，攻下则处于危险境地，都很难救治。热病及大病之后，大多因此致死，不可不谨慎。
孙思邈又说：新病初愈，只能吃稀粥，宁可少吃让自己感到饥饿，千万不要吃撑。不要吃其他任何食物，即使想吃也不要给。过一段时间逐渐好转后，可以逐渐吃羊肉和白米粥。如果是肉汁、羹汤，可以吃野鸡、兔子、鹿肉，不可以吃猪肉和狗肉。新病初愈后，应当安静卧床休息，千万不要早起梳头洗脸。这不仅会劳累身体，也不可以多说话、用心思虑，以免精神劳损疲劳。凡此种种都会导致劳复。所以督邮顾子献得病初愈后，华佗诊脉说：虽然病愈但身体依然虚弱，尚未恢复，阳气不足，千万不要从事劳累之事。其他的劳累还可以忍受，如果是房事劳累则会导致死亡，会出现舌头吐出数寸长的症状。他的妻子听说丈夫病愈，从百余里外赶来探望，经过一夜同房，中间过了三天，出现发热、牙关紧闭的症状，临死前舌头伸出数寸而死。病刚痊愈，未满一百天，气力尚未平复，就进行房事的，几乎没有不死的人。古代有个名叫盖正的人，病愈后六十天，已经能行走射箭打猎，结果因房事导致吐涎而死。最近有一个读书人，大病初愈十多天，犯了房事，小腹急痛，手足拘挛而死。
孙思邈又说：时令病初愈后，未满五天，吃各种肉类和面食，病情发作一定会使人困顿。
孙思邈又说：病愈后刚起身，饮酒及吃韭菜，病情会再次发作。
孙思邈又说：新病初愈吃生鱼鲜，腹泻一定不止；吃生菜，终身面色不再红润；吃生果及羊肉，必然导致胸膈以上热气蒸腾；吃狗肉、羊肉等，必然导致骨中蒸热；吃鱼肉、瓜果、生菜，会让人身体浮肿；吃蒜和生鱼片，疾病会再次发作，必然导致极度困顿。新近汗出病解，喝冷水，会导致心包寒冷，使人虚弱，补益也无法恢复。郭雍说：伤寒作为热毒类疾病，不可不谨慎警惕其后续反应，是害怕这种毒邪再次发作。一次已经过分严重了，难道还能再来一次吗？况且饮酒、吃枣、羊狗肉，都是大热的食物，因此导致复发，没有不极度困顿的。而且发汗、泻下之后，表里俱虚，胃气困弱，吃得过多、吃生冷食物，以及稍有劳动，都必然导致复发，能不谨慎吗？郭雍见到北方多有此类疾病，也有调养的方法：病愈之后，三天之内，只吃白粥，连说话也要忌讳。三天之后，粥里稍微加些味道。六天之后，才吃最软的饭，稍微加些面条丝、葱蒜羹。切忌梳头洗手。这个病最初是从脚部发起的，所以即使二十天后也不敢洗脚，触犯它必然导致复发。前面的论述有的说忌羊肉，有的说忌猪肉，说法不同，其实猪羊肉都要忌食。猪肉容易导致动风腹泻，羊肉容易导致热邪复发。北方土地病愈一两个月后，后来有人敢吃猪肉的，而羊肉近期也需忌口两个月，远则须百日。还有那种完全康复的人，应当少量食用，不要多吃。北方的羊肉羹，其热性尤其厉害，而洛原一带的猪肉，不太容易引发疾病。从西北到秦晋地区，南至汉水以南，猪肉则不可食用，秦晋地区尤为严重。南方猪羊也多，有病时仍需用心选择。因为大病之后，脏腑气血与平日不同。禁忌三日如法调养，则七日可保平安；七日如法，则十四日、二十一日可保平安；二十一日如法，则一月、三月可保平安。让他在初期调养护理得力，亲眼目睹这样的人，没有不迅速康复的。至于房事，必须忌满一百天以后。孙氏的论述，一个字也不可忽视。因为一旦劳复之后，病情必比前次发病时更困重；再次复发，又比第一次复发时更困重。何况还有第三次、第四次复发，几乎承受不了这种困重。因此往往因病复发而死。富贵人家大族，多有娇纵的女儿，又在发汗、泻下之后，肠胃空虚，急切想要进食，虽然吃了但不能消化，必然致病，难以劝说。全在于父母明白道理，左右有能调和之人来调节，才可以。如果病患初愈后，只喜欢吃白粥，则永远不会有祸患了。
《千金方》说：伤寒初愈后，再次出现头痛、高热、烦闷，宜服用黄龙汤。
《千金方》又说：男子新病初愈，亲近房事而复发的，宜服用赤帛烧散。
《千金方》又说：病后早起，以及因饮食过多、劳累而复发者，用鼠屎豉汤。崔氏方加入栀子。
《千金方》又说：食饱不消，劳复且脉象实者，宜用栀子香豉鼠屎大黄方。
《千金方》又说：劳复，气息将绝者，宜用麦门冬汤。起死回生，困倦者有效。
《千金方》又说：伤寒初愈一年后，心下停聚水饮，不能进食者，宜用地黄白术面汤方。
庞安时（字安常，世称庞氏）说：病刚痊愈后，气血津液衰耗，千万不要做各种活动。凡是言语思虑劳神，梳洗沐浴，体力劳动，劳动就会产生热邪，而疾病像原来一样复发。另外，新病初愈后，精髓枯燥，千万不可行房事，触犯必然死亡，就像顾子献那样。这名叫女劳复。又不是阴阳易。《素问》有言：吃得太多则难以消化，疾病复发像原来一样，这名叫食复。新病初愈，强壮的人需足月两个月，虚弱的人需足月一百天，就不会再复发了。
庞安时说：天行病（流行性传染病）劳复，头痛，四肢疼痛，宜用葱豉鼠屎汤。此汤最为奇妙。
庞安时说：天行病劳复出现发热，早晨到晚上则腰脊疼痛，头项强直沉重，宜用葛根姜豉汤。
庞安时说：伤寒已愈，劳复如初，脉浮无汗者，宜用桂枝栀子汤。自汗出的，去掉麻黄。
庞安时说：伤寒劳复如初，自汗出者，脉浮，烦躁严重，宜用栀子石膏香豉汤加雄鼠屎。
庞安时说：病刚平复后，劳动发热，热气攻冲胸部，手足拘急抽搐，像中风的样子，宜用栝蒌竹茹汤。
庞安时说：天行病初愈后，劳复发热，呕吐不能进食者，宜用芦根橘皮汤。
庞安时说：男子房劳导致复发者，宜用鼠屎薤根汤。兼治阴阳易，神验。
庞安时说：男子房劳复发，牙关紧闭，舌头伸出者死。刚开始劳复，百节疼痛如被打，浑身沉重，恍惚失措，脉促而绝，不可治。或者有吐涎不止，或者有谵语妄乱者，不治。
庞安时说：妇人病未平复，因丈夫触动，少腹及阴部急痛，腰胯痛，四肢不能举动，无热症者，用附子黄芩汤。
《活人书》说：新病初愈，血气尚虚，津液未复，因而劳动生热，热气重新回到经络，名叫劳复。张仲景说：用小柴胡汤主治。又有食复者，大病新愈，脾胃尚弱，强行进食过多，停积不化，因而发热，名叫食复。张仲景在枳实栀子汤后说：如果有宿食者，加大黄如博棋子五六枚，服用后痊愈。广济疗复雄鼠屎汤，许仁则七味葱白汤，都可以选用。郭雍说：病愈后，梳洗沐浴等事项，都容易禁止，只有肠胃空虚时食欲不止，所以多发生食复。然而劳复之中，服药也容易见效，所担心的是反复发作罢了。
The *Suwen* (Basic Questions) states: When a febrile disease has just subsided, why does residual heat sometimes remain? Qibo replied: In cases of residual heat, it is because food was forcibly consumed while the pathogenic heat was still intense. In such instances, although the disease has declined, heat remains latent within. The qi generated from the ingested grain combats with the residual heat, and the two heats merge, resulting in residual heat. How should this residual heat be treated? It is answered: Observe the deficiency or excess of the patient's constitution, and regulate the rebellious or smooth flow of qi; thus, the disease can certainly be cured.
The *Suwen* further states: What dietary prohibitions apply during a febrile disease? Qibo replied: When the symptoms of a febrile disease have slightly subsided, consuming meat will cause recurrence (*shi fu*, dietary relapse), and overeating will leave residual heat (*yi*). These are the prohibitions.
Zhang Zhongjing stated: For patients recovering from a major illness who suffer from relapse due to exertion (*lao fu*), Zhi Shi Zhi Zi Chi Tang (Immature Bitter Orange, Gardenia, and Fermented Soybean Decoction) is the primary treatment.
He also stated: After recovery from Shanghan (Cold Damage), if fever recurs, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is indicated. If the pulse is floating, resolve the exterior through sweating; if the pulse is sunken and excess (or tight), resolve the interior through purgation. Chang Qi stated that for sweating, Chai Hu Gui Zhi Tang (Bupleurum and Cinnamon Twig Decoction) is suitable, and for purgation, Tiao Wei Cheng Qi Tang (Regulate the Stomach and Direct Downward Decoction) is suitable.
He also stated: After recovery from a major illness, if there is fluid accumulation below the waist, Mu Li Ze Xie San (Oyster Shell and Alisma Powder) is indicated.
He also stated: After recovery from a major illness, if the patient frequently spits saliva without relief for a long time, it is due to cold in the chest. Pill medicines should be used to warm the middle jiao; Li Zhong Wan (Regulate the Middle Pill) is appropriate.
He also stated: After the resolution of Shanghan, if the patient is emaciated, short of breath, and experiences rebellious qi leading to nausea, Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction) is indicated.
He also stated: If the patient’s pulse has normalized, but they feel slight vexation in the evening, it is because the disease has just healed, people force-feed them, and the spleen and stomach qi are still weak, unable to digest the food, causing slight vexation. Reducing food intake will lead to recovery.
Hua Tu (courtesy name Yuanhua) stated: After recovery from seasonal diseases, alcohol, meat, five pungent spices (garlic, chives, leeks, scallions, asafetida), oily noodles, raw/cold foods, sour/slick foods, and sexual intercourse must all be prohibited. This is the general principle.
Sun Simiao (honored as Zhenren) stated: After a febrile disease has just healed, or following a major illness, consuming pork, mutton, blood products, fatty fish, or greasy foods will inevitably cause severe diarrhea, which physicians cannot treat, leading to death. If one consumes cakes, millet, malt sugar, dried meat, raw fish slices, roasted meat, dates, chestnuts, various fruits, and jerky, or other hard-to-digest foods, the weak stomach qi cannot digest them, leading to stagnation and renewed heat. If purgatives are used, stomach qi becomes deficient and cold, causing incontinence; if not used, death ensues. Both outcomes are difficult to save. Many die after febrile or major illnesses due to this; caution is essential.
Sun Simiao further stated: For new recoveries, only gruel should be eaten. It is better to eat little and remain slightly hungry than to become full. Do not consume other foods, even if desired. As time passes and condition improves, lamb and white rice gruel can be gradually introduced. Broths may include pheasant, rabbit, or venison, but not pork or dog meat. New recoveries should rest quietly in bed. Early rising, combing hair, or washing the face should be avoided, as these labor the body. Excessive talking or mental exertion should also be avoided, as these cause mental fatigue. All these factors lead to *lao fu* (exertional relapse). For example, Gu Zixian, a district inspector, recovered from illness. Hua Shu diagnosed his pulse and said, "Although recovered, he is still weak and not fully restored; yang qi is insufficient. Avoid labor. Other labors are bearable, but sexual labor leads to death, characterized by the tongue protruding several inches." His wife traveled over a hundred li to visit him. After intercourse overnight, three days later he developed fever and trismus. He died with his tongue protruding several inches. Those who engage in sexual activity within one hundred days of recovery, when qi and strength are not yet restored, almost invariably die. An ancient man named Gai Zheng, sixty days after recovery, could walk and hunt, but died from salivation after sexual activity. Recently, a scholar engaged in sexual activity ten days after a major illness, suffered lower abdominal pain and limb spasms, and died.
Sun Simiao also stated: Within five days of recovering from a seasonal disease, eating any meat or noodles will cause the disease to recur with severe debility.
He also stated: Rising shortly after recovery and consuming alcohol or chives will cause the disease to recur.
He also stated: Eating raw fish or fresh seafood after new recovery causes unceasing diarrhea. Eating raw vegetables causes lifelong dull complexion. Eating raw fruits or lamb causes steaming heat above the diaphragm. Eating dog or mutton causes steaming heat in the bones. Eating fish, melons, or raw vegetables causes edema. Eating garlic and raw fish causes disease recurrence and severe debility. Drinking cold water immediately after sweating resolves the exterior, causing cold in the pericardium and weakness that cannot be replenished. Gu Yong stated: Shanghan and other heat-toxin diseases require strict vigilance against sequelae, fearing the reactivation of toxins. One instance is already severe; how much more so a second? Alcohol, dates, lamb, and dog meat are hot-natured foods; consuming them causes relapse and severe debility. After sweating or purging, both exterior and interior are deficient, and stomach qi is weak. Overeating, consuming raw/cold foods, or slight exertion will inevitably cause relapse. Is caution not necessary? Gu Yong observed many such cases in the north and noted调养 (nourishing/regulating) methods: For three days post-recovery, eat only white rice gruel and avoid speaking. After three days, add flavor to the gruel. After six days, eat very soft rice, adding thin noodles, scallion, and garlic soup. Combing hair and washing hands/feet are strictly forbidden. Since the disease often originates from the feet, even after twenty days, foot washing must be avoided to prevent relapse. Earlier texts differed on avoiding lamb vs. pork, but both should be avoided. Pork induces wind and diarrhea; lamb induces heat relapse. In northern regions, pork may be tolerated after one to two months, but lamb requires two months to a hundred days. Even fully recovered individuals should eat sparingly. Northern lamb broth is particularly heating; pork from Luoyuan rarely causes issues. However, from northwest to Qin/Jin, south to Han River, pork is forbidden, especially in Qin/Jin. Southern regions have abundant pork and lamb, but selection is crucial post-illness as zang-fu and qi-blood differ from normal times. Adhering to prohibitions for three days ensures safety for seven days; seven days ensures fourteen and twenty-one days; twenty-one days ensures one to three months. Proper initial care leads to rapid recovery. Sexual abstinence is required for one hundred days. Sun’s words must not be ignored. One relapse makes the condition worse than the original; a second relapse is worse than the first. Multiple relapses are unbearable, often leading to death. Wealthy families often indulge daughters; after sweating/purging, empty guts crave food, leading to indigestion and illness. Parents must understand, and attendants must regulate diet. If the patient prefers only white rice gruel post-recovery, disaster is averted.
*Qianjin Fang* (Prescriptions Worth a Thousand Gold) states: After Shanghan recovery, if headache, high fever, and vexation recur, Huang Long Tang (Yellow Dragon Decoction) is indicated.
It also states: For men recovering from new illness who relapse due to sexual activity, Chi Bi Shao San (Burnt Red Silk Powder) is indicated.
It also states: For relapse due to early rising or overexertion/diet, Shu Shi Chi Tang (Mouse Dropping and Fermented Soybean Decoction) is used. Cui’s formula adds Zhi Zi (Gardenia).
It also states: For indigestion after full meals and relapse with an excess pulse, Zhi Zi Xiang Chi Shu Shi Da Huang Fang (Gardenia, Aromatic Fermented Soybean, Mouse Dropping, and Rhubarb Formula) is indicated.
It also states: For *lao fu* with near-extinction of qi, Mai Men Dong Tang (Ophiopogon Decoction) is indicated. It revives the dying and alleviates exhaustion.
It also states: One year after Shanghan recovery, if water retention under the heart prevents eating, Di Huang Bai Zhu Mian Tang (Rehmannia and Atractylodes Noodle Decoction) is indicated.
Pang Anshi (known as Pang Shi) stated: After new recovery, qi, blood, and fluids are depleted. Avoid all activities. Mental labor from speech/thought, physical labor from grooming/bathing/exertion generates heat, causing relapse. Furthermore, essence and marrow are dry post-recovery; sexual activity is strictly forbidden and fatal, as seen in Gu Zixian. This is called *nv lao fu* (female-induced exertional relapse), distinct from *yin yang yi*. The *Suwen* notes that overeating causes indigestion and relapse, called *shi fu* (dietary relapse). Strong persons need two months of rest; weak persons need one hundred days to prevent relapse.
Pang Shi also stated: For epidemic *lao fu* with headache and limb pain, Cong Chi Shu Shi Tang (Scallion, Fermented Soybean, and Mouse Dropping Decoction) is excellent.
For epidemic *lao fu* with fever worsening from morning to night, accompanied by backache and stiff neck, Ge Gen Jiang Chi Tang (Kudzu, Ginger, and Fermented Soybean Decoction) is indicated.
For Shanghan relapse resembling the initial state with floating pulse and no sweat, Gui Zhi Zhi Zi Tang (Cinnamon Twig and Gardenia Decoction) is indicated. Remove Ma Huang (Ephedra) if spontaneous sweating occurs.
For Shanghan relapse with floating pulse and no sweat, the condition is severe.
For Shanghan relapse with spontaneous sweating, floating pulse, and severe irritability, Zhi Zi Shi Gao Xiang Chi Tang (Gardenia, Gypsum, and Fermented Soybean Decoction) plus male mouse droppings is indicated.
After recent recovery, if exertion causes fever, heat attacking the chest, and limb spasms resembling wind-stroke, Gua Lou Zhu Ru Tang (Trichosanthes and Bamboo Sap Decoction) is indicated.
For epidemic recovery relapse with fever, vomiting, and inability to eat, Lu Gen Ju Pi Tang (Phragmites Root and Tangerine Peel Decoction) is indicated.
For men relapsing due to sexual labor, Shu Shi Xie Gen Tang (Mouse Dropping and Shallot Root Decoction) is indicated. It also treats *yin yang yi* effectively.
For men relapsing from sexual labor with trismus and protruding tongue, death occurs. Initial *lao fu* with joint pain like beating, heaviness, confusion, and intermittent pulse is incurable. Uncontrollable salivation or delirious agitation is also incurable.
For women whose illness has not fully resolved, if moved by their husband, causing lower abdominal/genital pain, lumbar/hip pain, and immobility without fever, Fu Zi Huang Qin Tang (Aconite and Scutellaria Decoction) is indicated.
*Huoren Shu* (Book of Vitality) stated: New recovery leaves qi and blood deficient and fluids unreplenished. Exertion generates heat, which returns to the meridians, called *lao fu*. Zhang Zhongjing prescribed Xiao Chai Hu Tang. Dietary relapse (*shi fu*) occurs when strong eating after major illness causes stagnation and fever. Zhang Zhongjing added Rhubarb to Zhi Shi Zhi Zi Tang for retained food. Guang Ji’s Xiong Shu Shi Tang and Xu Renze’s Qi Wei Cong Bai Tang are also selectable options. Gu Yong noted that post-recovery grooming is easy to prohibit, but hunger leads to overeating and *shi fu*. While medication helps *lao fu*, repeated relapses are the concern.
