48. 疾病初愈时，脏腑功能均显虚弱，营卫之气与肠胃功能尚未恢复调和。若饮食过量或过度劳累，会导致余热复发；此时宜用枳实栀子大黄汤治疗以助康复。若脉象浮浅且有表证，可用发汗法解表；若脉象沉潜且有里证，可用泻下法通里；若无明显的表里症状，则用小柴胡汤进行和解调理。若出现口燥、心烦口渴且喜呕吐的症状，宜用竹叶石膏汤主治。若因内伤导致气虚而引发劳复，应以补中益气汤为主治方剂。若因房事不节导致阴液亏损，宜用六味地黄汤（加干地黄）主治；若兼有气虚，应加倍加入人参煎服。
【注释】大病初愈之后，脏腑的气血皆处于不足状态，营卫之气未通畅，肠胃功能未调和，此时只宜食用白米粥并静养休息。如果进食过多，脾胃虚弱难以消化，因而再次出现烦热症状，称为“食复”。如果过度劳累再次产生烦热，称为“劳复”。对于劳复患者，适宜使用枳实栀子豉汤通过发汗法治疗。对于食复患者，适宜使用枳实栀子豉汤加大黄通过泻下法治疗。脉象浮浅且有表证的，适宜用枳实栀子豉汤通过发汗法解除病邪。脉象沉潜且有里证的，适宜用枳实栀子豉汤加大黄通过泻下法解除病邪。如果没有表证和里证表现的，适宜用小柴胡汤进行和解治疗。出现口燥、心烦口渴且喜欢呕吐的，适宜用竹叶石膏汤主治。如果是因内伤气虚导致的劳复，适宜用补中益气汤主治。如果是因房事过度导致阴精亏损的，适宜用六味生干地黄汤主治；若气虚明显，应加倍加入人参煎服。
49. 房劳复与阴阳易这两种病情不同，但症状表现相似。病后发生性行为导致自身复发，称为房劳复；疾病传染给未患病的一方，称为阴阳易。男女双方患病初愈时均适用烧裈散治疗。其症状包括少腹部拘急疼痛并牵引至阴部，身体沉重、气息短少、头晕目眩，四肢拘挛痉挛，热气上冲胸部。
【注释】男女双方在疾病初愈时进行性交，因而导致疾病复发，称为“房劳复”。男女双方疾病初愈时进行性交，患病男性传染给未患病的妇女，或患病女性传染给未患病的男性，称为“阴阳易”，即交换的意思。患有此类疾病的，男性取女性的内裤裆部，女性取男性的内裤裆部，烧成灰末，用开水或酒送服，每日三次即可痊愈。少腹部拘急疼痛牵引至阴部，身体沉重、气息短少，头晕目眩，四肢拘挛痉挛，热气上冲胸部，这些都是该病的症状表现。
48. When a disease has just healed, the Zang-Fu organs are all deficient, and the Ying-Wei (Nutritive and Defensive Qi) and the stomach and intestines have not yet regained harmony. Overeating or overexertion may cause recurrent heat; in such cases, Zhishi Zhizi Dahuang Tang (Immature Bitter Orange, Gardenia, and Rhubarb Decoction) should be used to facilitate recovery. If the pulse is floating indicating exterior syndrome, sweating method should be employed to resolve the exterior. If the pulse is sunken indicating interior syndrome, purgative method should be employed to resolve the interior. If there are no obvious exterior or interior signs, Xiaochaihu Tang (Minor Bupleurum Decoction) should be used for harmonizing treatment. If symptoms include dry mouth, vexation, thirst, and a desire to vomit, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is indicated. If labor recurrence is caused by internal injury and Qi deficiency, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) is the primary formula. If Yin deficiency results from sexual indiscretion, Liuwei Dihuang Tang (Six-Ingredient Rehmannia Pill with Dry Rehmannia) is indicated; if Qi is also deficient, the dosage of Renshen (Ginseng Root) should be doubled.
[Annotation] After the recent healing of a major illness, the Qi and Blood of the Zang-Fu organs are all insufficient, the Ying-Wei circulation is not unobstructed, and the function of the stomach and intestines is not harmonized. At this time, only plain rice gruel and quiet rest are suitable. If food intake is excessive, the weak spleen and stomach cannot digest it properly, leading to recurrent vexation and heat, which is called "Food Recurrence" (Shi Fu). If overexertion leads to recurrent heat and vexation, it is called "Labor Recurrence" (Lao Fu). For labor recurrence, Zhishi Zhizi Chi Tang (Immature Bitter Orange, Gardenia, and Fermented Soybean Decoction) should be used to induce sweating. For food recurrence, Zhishi Zhizi Chi Tang added with Dahuang (Rhubarb Root and Rhizome) should be used to induce purgation. If the pulse is floating with exterior signs, Zhishi Zhizi Chi Tang should be used to resolve via sweating. If the pulse is sunken with interior signs, Zhishi Zhizi Chi Tang added with Dahuang should be used to resolve via purgation. If there are no exterior or interior syndromes, Xiaochaihu Tang should be used for harmonization. If there is dry mouth, vexation, thirst, and a preference for vomiting, Zhuye Shigao Tang is indicated. If labor recurrence is due to internal injury and Qi deficiency, Buzhong Yiqi Tang is indicated. If Yin essence is depleted due to sexual activity, Liuwei Shengan Dihuang Tang (Six-Ingredient Raw Rehmannia Decoction) is indicated; if Qi is deficient, the dosage of Renshen should be significantly increased.
49. Labor Recurrence via Sexual Activity (Fang Lao Fu) and Yin-Yang Exchange (Yin Yang Yi) differ in pathology but present with similar symptoms. Recurrence of one's own illness after sexual activity post-recovery is called Fang Lao Fu; transmission of the disease to an unaffected partner is called Yin Yang Yi. Both men and women suffering from these conditions are treated with Shao Kun San (Burnt Undergarment Powder). Symptoms include urgency and pain in the lower abdomen radiating to the genitalia, heaviness of the body, shortness of breath, dizziness and vertigo, spasms and contracture of the limbs, and rising heat rushing to the chest.
[Annotation] When men and women engage in intercourse shortly after recovering from illness, causing the disease to recur, it is called "Fang Lao Fu". When men and women engage in intercourse shortly after recovery, and the sick man transmits the disease to the healthy woman, or the sick woman transmits it to the healthy man, it is called "Yin Yang Yi", meaning exchange. For those afflicted with this condition, the crotch of the female's undergarment is taken for men, and the crotch of the male's undergarment is taken for women; these are burned to ash and administered three times daily with boiling water or wine for cure. Urgency and pain in the lower abdomen radiating to the genitalia, body heaviness, shortness of breath, dizziness and vertigo, limb spasms, and heat rushing to the chest are its clinical manifestations.
