凡热病新瘥，及大病之后，食猪肉及肠血肥鱼油腻等，必大下痢，医不能治也，必至于
死。若食饼饵粢黍饴脯 炙枣栗诸果，及坚实难消之物，胃气尚虚弱，不能消化，必更结热，
适以药下之，则胃中虚冷，大利难禁，不下必死，下之复危，皆难救也。热病之后，多坐
此死，不可不慎也。
病新瘥，但得食糜粥，宁可少食令饥，慎勿饱，不得他有所食，虽思之勿与，引日转久
可渐食羊肉糜若兔雉鹿肉，慎不可食猪犬肉也。
新瘥后，当静卧，慎勿令人梳头洗面，非但体劳，亦不可多言语用心使意劳，凡此皆令
劳复。故督邮顾子献得病已瘥未健，诣华 视脉， 曰∶虽瘥尚虚未复，阳气不足，勿为劳
事，余劳尚可，御内即死，临死当吐舌数寸。其妻闻其夫病除，从百余里来省之，止宿交
接，中间三日发病，舌出数寸而死。病新瘥未经百日，气未平复，而以房室者，略无不死也。
盖正疾愈后六十日，己能行射猎，以房事则吐涎而死。及热病房室，名为阴阳易之病，皆难
治，多死。近者有一士大夫，小得伤寒，发汗已十余日，能乘马行来，自谓平复，故以房室，

治疗大病初愈后因劳累而复发者，使用枳实栀子汤方。
枳实（三枚，经炙烤处理） 栀子（十四枚，掰开）
以上两味药，用醋浆一斗，先煎煮至六升，再放入药物煎煮至三升，加入豆豉一升，再煎煮五六沸，滤去药渣，分两次服用，服药后覆盖衣被以取汗。如果有宿食停滞的情况，加入如棋子大小的一块大黄。（出自《外台秘要》卷二）
治疗因劳累复发的“大青汤”方。
大青（四两） 甘草（二两，经炙烤处理） 阿胶（二两，经炙烤处理） 香豉（二两）
以上四味药，切碎，用水一斗，煎煮至三升，滤去药渣，温服一升，每日五到六次。如果症状缓解后又发作，应持续服药，保持体内有药力。若伴有口渴或严重下痢，此方效果良好。应先煎煮大青和甘草，取汁四升，滤去药渣，再加入阿胶和豆豉，待阿胶完全溶化后过滤去除豆豉，不要让豆豉煮烂，应当预先浸泡阿胶使其溶解。忌食白菜、海藻。（出自《外台秘要》卷二）
治疗伤寒大病初愈后，轻微劳累即导致鼻出血者，使用牡蛎散及丸方。
左顾牡蛎（十分，煅烧） 石膏（五分）
以上两味药，捣成粉末，用酒送服一方寸匕，每日二到四次。也可以制成蜜丸，如梧桐子大小，用酒送服十五丸。（出自《外台秘要》卷二）
治疗重病刚初愈时早起劳作，以及饮食过多，导致病情复发近乎死亡者。
将鳖甲烧成末，服用一方寸匕，忌食苋菜。（出自《外台秘要》卷四）
治疗伤寒初愈后，再次出现头痛、高热、烦闷者。
服用黄龙汤五合，每日三次。（出自《医心方》卷十四）
凡是热病刚刚痊愈，以及大病之后，食用猪肉、猪肠、血制品、肥鱼、油腻等食物，必然会导致严重腹泻，医生难以治愈，最终会导致死亡。如果食用饼饵、粢黍、饴糖、肉干、烤枣栗子等各种水果，以及坚硬难消化的食物，由于胃气仍然虚弱，无法消化，必然再次产生内热。此时若恰好用泻下药治疗，则会导致胃中虚冷，严重腹泻无法控制；若不泻下则必死，泻下则更加危险，都难以救治。热病之后，许多人因此而死，不可不谨慎。
疾病刚痊愈时，只能吃稀粥，宁可少吃感到饥饿，千万不要吃撑，不得食用其他食物，即使想吃也不要给，经过一段时间逐渐好转后，可以逐渐食用羊肉糜或兔肉、野鸡、鹿肉，千万不可食用猪肉和狗肉。
大病初愈后，应当安静卧床休息，切勿让人梳头洗脸，这不仅会使身体劳累，也不可多说话或用脑过度导致心神疲劳，凡此种种都会导致劳复。例如督邮顾子献得病已愈但未完全康复，去拜访华佗诊脉，华佗说：“虽然病愈但身体尚虚未恢复，阳气不足，不要从事劳累之事，一般的劳累还可以忍受，但若进行房事就会死亡，临死前舌头会伸出数寸。”他的妻子听说丈夫病除，从百余里外来探望，留宿并发生性关系，中间三天发病，舌头伸出数寸而死。疾病刚痊愈未满百日，气血尚未平复，而行房事者，几乎没有不死的情况。大概正病痊愈后六十天，已经能骑马射箭，若行房事则会吐涎沫而死。此外，在热病期间行房事，称为“阴阳易”病，都难以治疗，大多死亡。最近有一位士大夫，患轻微伤寒，发汗后十余日，能骑马行走，自认为已康复，故行房事，则……
For the recurrence of illness due to overexertion after recovery from a major disease, use the Zhishi Zhizi Tang (Bitter Orange and Gardenia Decoction) formula.
Zhishi (Immature Bitter Orange, three pieces, processed by roasting) Zhizi (Gardenia Fruit, fourteen pieces, broken open)
Take the above two herbs, add one dou of vinegar juice, first decoct until six sheng remain, then add the herbs and decoct until three sheng remain. Add Chi Xiao Dou (Prepared Soybean, one sheng), boil for five or six boils, filter out the dregs, divide into two doses, take orally, and cover with blankets to induce sweating. If there is retained food stagnation, add Dahuang (Rhubarb Root and Rhizome) the size of a chess piece. (From *Waitai Miyao*, Vol. 2)
For recurrence due to overexertion, use the Daqing Tang (Great Cyan Decoction) formula.
Daqing (Qing Dai Plant, four liang) Gancao (Licorice Root, two liang, processed by roasting) Ejiao (Donkey-hide Gelatin, two liang, processed by roasting) Xiangchi (Prepared Soybean, two liang)
Cut the above four herbs, add one dou of water, decoct until three sheng remain, filter out the dregs, take one sheng warm, five to six times daily. If symptoms resolve and then recur, continue administering the decoction to maintain therapeutic levels. This formula is particularly effective for thirst or severe diarrhea. First decoct Daqing and Gancao, obtain four sheng of liquid, filter out the dregs, then add Ejiao and Xiangchi. Allow Ejiao to dissolve completely, then filter out the Xiangchi without letting it disintegrate; pre-soak Ejiao to facilitate dissolution. Avoid eating Chinese cabbage (Songcai) and seaweed. (From *Waitai Miyao*, Vol. 2)
For epistaxis occurring after minor exertion following recovery from Shanghan (Cold Damage), use the Muli San (Oyster Shell Powder) and Wan (Pill) formula.
Zuo Gu Muli (Left-facing Oyster Shell, ten fen, calcined) Shigao (Gypsum Fibrosum, five fen)
Grind the above two herbs into powder, administer one fangcun bi (a square-inch measure) with wine, two to four times daily. Alternatively, make honey pills the size of wutong seeds, administer fifteen pills with wine. (From *Waitai Miyao*, Vol. 2)
For near-fatal recurrence caused by rising early and exerting oneself, or excessive eating, shortly after recovering from a severe illness.
Burn Bi Jia (Turtle Carapace and Plastron) into powder, administer one fangcun bi. Avoid eating Amaranth (Xiancai). (From *Waitai Miyao*, Vol. 4)
For headache, high fever, and restlessness recurring after recovery from Shanghan.
Fuyong Huanglong Tang (Yellow Dragon Decoction), five he, three times daily. (From *Ishinpo*, Vol. 14)
Generally, after recent recovery from febrile diseases or major illnesses, consuming pork, intestines, blood products, fatty fish, or greasy foods will inevitably cause severe diarrhea, which physicians cannot treat, leading to death. Consuming cakes, millet, malt sugar, dried meat, roasted dates, chestnuts, fruits, or hard-to-digest items, when stomach qi is still weak and unable to digest, will inevitably generate internal heat. If purgatives are administered at this time, it will cause cold deficiency in the stomach, making severe diarrhea uncontrollable. Not purging leads to death; purging leads to critical danger. Both are difficult to save. Many die from this after febrile diseases; caution is essential.
When an illness has just healed, only gruel should be eaten. It is better to eat little and feel hungry than to become full. Do not consume other foods; even if desired, do not provide them. After some time, as health gradually returns, mutton gruel or rabbit, pheasant, or venison can be gradually introduced. Pork and dog meat must absolutely be avoided.
After recent recovery, one should lie quietly. Do not allow others to comb hair or wash the face. Not only does this cause physical fatigue, but excessive talking or mental exertion also causes spirit fatigue. All these lead to recurrence due to overexertion (Laofu). For example, Governor Gu Zixian had recovered but was not fully strong. He visited Hua Tuo for pulse diagnosis. Hua Tuo said: "Although the disease has resolved, you are still deficient and un-recovered, with insufficient yang qi. Do not engage in strenuous activity. General fatigue is tolerable, but engaging in sexual intercourse will cause death, and upon death, your tongue will protrude several inches." His wife, hearing of his recovery, traveled over a hundred li to visit him. They stayed overnight and engaged in intercourse. Three days later, he fell ill, his tongue protruded several inches, and he died. Anyone engaging in sexual intercourse within one hundred days of recent recovery, while qi and blood have not yet stabilized, will almost certainly die. Generally, sixty days after the main illness has healed, when one can ride horses and hunt, engaging in sexual intercourse will cause vomiting of saliva and death. Furthermore, engaging in sexual intercourse during a febrile disease is called the "Yinyang Yi" (Yin-Yang Transmission) disease, which is difficult to treat and often fatal. Recently, a scholar suffered from mild Shanghan. After inducing sweating, more than ten days passed, and he could ride a horse, believing himself recovered. Consequently, he engaged in sexual intercourse, and then...
