许仁则云∶此病复发，不但起动劳役，或因饮食稍多，或因言语过分，或缘视听不节，
或为动转不常，皆成此复。若复甚者，乃至不救，剧于初得病时，不可以复发而云轻易，劳

上药用劳水煎之，三分减二，去滓。分温三服，相去行八九里。如觉欲汗，渐渐覆之。
兼主伤寒。忌芜荑。
又依前葱白等七味饮服之得可，但适寒温将息，以取安稳，若不觉可，宜合葳蕤等五味

许仁则说：这种病复发，不仅仅是因为过度劳累，也可能是因为饮食稍多，或者说话过多，或者视听没有节制，或者行动起居不规律，都会导致这种复发。如果复发严重的，甚至会导致死亡，比最初得病时更严重，不能因为是复发就认为它轻微。劳复的症状表现就像伤寒初起时一样。对于这种情况，适宜使用葱白等七味饮，服用后逐渐覆盖衣被以取汗的方法。
葱白连须（切一升） 干葛（切六合） 新豉（一合绵裹） 生姜（切二合） 生麦门冬（去心六合） 干地黄（六合） 劳水八升此水以杓扬之（一千过）
将上述药材用劳水煎煮，水量减少三分之二，滤去药渣。分三次温服，每次服药间隔行走八九里路。如果觉得要出汗，就逐渐加盖衣被。同时也主治伤寒。忌食芜荑。
又按照前面葱白等七味饮服用有效的话，只要注意寒温调摄，以求安稳，如果感觉效果不明显，适宜使用葳蕤等五味饮子服用方。
葳蕤（五两切） 葱白（切一升） 豉心（一升绵裹） 粳米（三合研碎） 雄鼠屎（七枚末之）
将上述药材用水七升，先煮豉以上药材取四升汁液，滤去药渣，加入粳米屑，煮至米烂熟后，加入鼠屎末搅拌调和。一次性服用。盖好被子安静躺卧，以出汗为痊愈。
另外凡是天行病（流行性传染病）痊愈后，按照常规应当逐渐恢复体力能行走，如果超过限度不堪劳累，身体气息虚弱消瘦，经常觉得头痛，嘴唇口干，忽冷忽热，发作有定时，或者虽然能行动运转，但在发病时节有前述症状的，名为天行后不了了，如果有这种情况，适宜使用地骨白皮等五味饮子、白薇等十味丸方，细细服用。
地骨白皮（三两） 知母（三两） 麦门冬（五两去心） 竹沥（一升） 白蜜（三合）
将上述药材切碎知母以上与麦门冬混合，然后用水六升，煎煮取二升汁液，滤去药渣，加入竹沥和蜂蜜搅拌调和。分三次温服，每次服药间隔相当于人行走十里路的时间。如果觉得虚弱，不能空腹一次性喝完，想间隔进食后服用也很好。同时也主治伤寒。
另外如果服用前面的地骨白皮等五味饮子无效，虽然不能完全退热，适宜使用白薇等十味丸方。
白薇（三两） 知母（四两） 地骨皮（三两） 干地黄（六两） 麦门冬（五两去心） 甘草（四两炙） 蜀漆（三两） 葳蕤（三两） 橘皮（二两） 人参（三两）
将上述药材细切，混合捣碎筛粉，用绢罗过滤成散剂，用蜂蜜和丸如梧桐子大小。初次服用时用温水送下十五丸，每天两次，逐渐增加至三十丸。服用三四天后，自己观察腹部情况，如果觉得热就在饭前服用，如果不能空腹喝水送下药丸，适宜使用乌梅等四味饮送服前面的药丸。忌食菘菜、海藻、芜荑等。
将上述药材切碎，用水六升，煮前三味药材取二升汁液，滤去药渣，加入白蜜搅拌调和，细细用来送服前面的药丸，多少冷暖，根据心意斟酌。即使不下药丸，只要觉得口干渴就饮用。（吴升相同）
Xu Renze stated: The recurrence of this disease is not only caused by excessive labor, but also may result from slightly overeating, speaking excessively, lack of moderation in hearing and seeing, or irregular movement and daily routine. All these factors can lead to such a recurrence. If the recurrence is severe, it may even be incurable and more critical than the initial onset; one must not consider it trivial because it is a relapse. The symptoms of "Lao Fu" (recurrence due to overexertion) are exactly like those at the beginning of Shanghan (Cold Damage). In such cases, it is appropriate to use Congbai Qiwei Yin (Scallion White Seven-Ingredient Decoction), covering the patient gradually after ingestion to induce sweating.
Scallion White with Roots (Cut, 1 Sheng) Gan Ge (Puerariae Radix, Cut, 6 He) Xin Chi (Fresh Fermented Soybean Paste, 1 He, wrapped in silk) Sheng Jiang (Fresh Ginger Root, Cut, 2 He) Sheng Maidong (Ophiopogonis Radix, Heart Removed, 6 He) Gan Dihuang (Rehmanniae Radix, 6 He) Lao Shui (Labor Water, 8 Sheng; this water is stirred vigorously with a ladle one thousand times)
Decoct the above herbs in Labor Water until the volume reduces by two-thirds. Strain the dregs. Divide into three warm doses. Walk approximately eight to nine Li between each dose. If one feels the urge to sweat, gradually cover with blankets. This formula also treats Shanghan. Avoid Yuan Yi (Chrysanthemi Fructus).
Furthermore, if taking the aforementioned Congbai Qiwei Yin yields improvement, maintain moderate temperature and rest to ensure stability. If no improvement is felt, it is appropriate to take Weirui Wuwei Yinzi (Weirui Five-Ingredient Drink).
Weirui (Polygonati Rhizoma, 5 Liang, cut) Cong Bai (Scallion White, 1 Sheng, cut) Chi Xin (Fermented Soybean Core, 1 Sheng, wrapped in silk) Jing Mi (Oryza Sativa Indica Concreta, 3 He, ground) Xiong Shu Shi (Male Rat Feces, 7 pieces, powdered)
Decoct the above herbs in 7 Sheng of water. First decoct Chi Xin and others to obtain 4 Sheng of juice. Strain the dregs, add Jing Mi powder, and cook until the rice is soft. Add the powdered rat feces and stir well. Take all at once. Cover with a blanket and lie quietly to induce sweating for recovery.
Additionally, generally after recovery from Tianxing Bing (Epidemic Febrile Disease), one should gradually regain strength to walk. If one exceeds limits and cannot endure exertion, resulting in weak Qi and emaciation, frequent headache, dry lips and mouth, alternating chills and fever occurring at regular intervals, or although able to move, experiencing previous symptoms during episodes, this is named "Tianxing Hou Buliaoliao" (Incomplete Recovery after Epidemic Disease). In such cases, it is appropriate to take Diguxuapi Wuwei Yinzi (Diguxuapi Five-Ingredient Drink) and Baiwei Shiwei Wan (Baiwei Ten-Ingredient Pill), taken slowly.
Diguxuapi (Lycii Cortex, 3 Liang) Zhi Mu (Anemarrhenae Rhizoma, 3 Liang) Maidong (Ophiopogonis Radix, 5 Liang, heart removed) Zhu Li (Bambusa Textilis Sap, 1 Sheng) Bai Mi (White Honey, 3 He)
Cut Zhi Mu and mix with Maidong. Decoct in 6 Sheng of water to obtain 2 Sheng. Strain the dregs, add Zhu Li and honey, and stir well. Divide into three warm doses. The interval between doses should be equivalent to walking ten Li. If feeling weak and unable to finish on an empty stomach, taking it after meals is also good. It also treats Shanghan.
If the aforementioned Diguxuapi Wuwei Yinzi is ineffective, although heat may not completely subside, it is appropriate to use Baiwei Shiwei Wan (Baiwei Ten-Ingredient Pill).
Baiwei (Clerodendri Radix, 3 Liang) Zhi Mu (Anemarrhenae Rhizoma, 4 Liang) Digupi (Lycii Cortex, 3 Liang) Gan Dihuang (Rehmanniae Radix, 6 Liang) Maidong (Ophiopogonis Radix, 5 Liang, heart removed) Gancao (Glycyrrhizae Radix et Rhizoma, 4 Liang, roasted) Shuqi (Perillae Folium, 3 Liang) Weirui (Polygonati Rhizoma, 3 Liang) Jupi (Citri Reticulatae Pericarpium, 2 Liang) Renshen (Ginseng Radix, 3 Liang)
Finely cut the above herbs, pound and sieve them. Pass through a silk sieve to make a powder. Mix with honey to form pills the size of Sophora seeds. Initially take 15 pills with water, twice daily. Gradually increase to 30 pills. After three to four days of administration, observe abdominal sensations. If feeling heat, take before meals. If unable to take with plain water on an empty stomach, it is appropriate to use Wumei Siwei Yin (Wumei Four-Ingredient Drink) to administer the pills. Avoid Songcai (Chinese Cabbage), Haizao (Sargassum), Yuan Yi, etc.
Wumei Yin Formula
Wumei (Mume Fructus, 10 pieces) Weirui (Polygonati Rhizoma, 5 Liang) Sheng Jiang (Fresh Ginger Root, 5 Liang) Bai Mi (White Honey, 1 He)
Cut the above herbs. Decoct the first three ingredients in 6 Sheng of water to obtain 2 Sheng. Strain the dregs, add white honey, and stir well. Use this liquid slowly to administer the aforementioned pills. Adjust quantity and temperature according to preference. Even if not taking pills, drink it whenever feeling dry mouth and thirst. (Same as Wu Sheng's record)
