一、劳倦饥饱不时，而致寒热往来者，以饥时脏气馁，劳时腠理开，腠理开则邪易感，
脏气馁则邪易入，所以饥饱劳倦不慎者，多令人为头痛发热恶寒等证。虽曰此由内伤，而实
有外感，虽有外感，而实以内伤。故东垣制补中益气汤，以参、 、归、术，而加之升、柴
，以助生长之气，使胃气上升，则气复于中，而阳达于外，此实和解之良法也。第今人以劳
倦伤阴，而精血受病者为尤多，则 、术之属，亦有不相宜者。兹余复制补阴益气煎，凡阳
虚于下，水亏不能作汗，而邪有不解者，此方尤胜之。愚有治脾三方并补中益气汤论，在后
饮食门，当参阅之。
一、劳倦感邪，以致伤寒，发热，头痛身痛，凡脉紧邪盛者，不得不从解散治之。若虚
本不甚，而表邪不解者，宜正柴胡饮。若外邪兼火者，一柴胡饮。外邪兼寒者，二柴胡饮。
若气血微虚者，三柴胡饮，或四柴胡饮。其有虚甚而邪不易解者，宜理阴煎，或大温中饮，
所不可缓也。
一、夏日暑热之时，或于道途，或于田野，过于劳倦，而身体薄弱者，最易伤暑，此亦
劳倦之属，论治详暑证门阳暑条中。
凡是因过度劳累和疲倦导致，且没有外感邪气的情况，或者身体虽然有轻微发热，但脉象表现为缓大而无力，完全不紧促数急，或者懒于言语、喜欢躺卧，或者身体经常出汗，这就是劳倦发热的证候，自然与外感引起的头痛、脉紧、筋骨酸痛等不同。治疗应当以补养为主，气机恢复后病症即可痊愈。虚损在阳分的，适宜使用四君子汤、五君子煎；虚损在阴分的，适宜使用三阴煎、五阴煎，或者大营煎、小营煎。如果是脾胃中气受损的，适宜使用理中汤、养中煎。如果是气血都虚弱的，适宜使用五福饮、八珍汤，或者十全大补汤。
一、因劳倦、饥饿或饱食不规律，而导致寒热往来的，是因为饥饿时脏腑之气虚弱，劳累时腠理（皮肤毛孔及肌肉纹理）开放，腠理开放则邪气容易侵入，脏腑之气虚弱则邪气容易进入体内，所以饮食饥饱不节制、劳倦不慎的人，多会出现头痛、发热、恶寒等症状。虽然说是由于内伤引起，但实际上兼有外感；虽然兼有外感，但根本原因在于内伤。因此李东垣制定了补中益气汤，用人参、[原文缺字，通常指黄芪]、当归、白术，并加入升麻、柴胡，来助长生长之气，使胃气上升，那么气就能恢复于中焦，阳气就能通达于体表，这确实是和解法的良方。只是如今人们因劳倦损伤阴分，导致精血生病的情况尤其多，那么人参、白术这类药物，也有不太适宜的时候。现在我另外制定补阴益气煎，凡是下焦阳虚，肾水亏虚不能化汗，而邪气未能解除的，这个方剂尤为优越。我有论述脾脏治疗的三个方子以及关于补中益气汤的文章，在后面饮食门中，应当参考阅读。
一、因劳倦感受邪气，导致伤寒、发热、头痛、身体疼痛，凡是脉紧、邪气盛实的，不得不从发散解表的方法治疗。如果正气虚损不是很严重，而表邪未解的，适宜使用正柴胡饮。如果外邪兼夹火邪的，使用一柴胡饮。外邪兼夹寒邪的，使用二柴胡饮。如果气血轻微虚弱的，使用三柴胡饮，或者四柴胡饮。如果有虚损非常严重而邪气不易解除的，适宜使用理阴煎，或者大温中饮，这是不可拖延的。
一、夏日暑热之时，或者在路上行走，或者在田野劳作，过于劳倦，且身体薄弱的人，最容易伤暑，这也属于劳倦的范畴，详细的治疗论述在暑证门的阳暑条中。
For cases caused by overexertion and fatigue without external pathogenic invasion, or where there is slight fever but the pulse is slow, large, and forceless, completely lacking in tightness and rapidity, or where there is reluctance to speak and a preference for lying down, or frequent sweating, this constitutes the syndrome of heat arising from exhaustion. It naturally differs from headache, tight pulse, and soreness/pain in bones and muscles caused by external invasions. Treatment should primarily focus on tonification and nourishment; once Qi recovers, the condition will resolve. For deficiency in the Yang aspect, Si Jun Zi Tang (Four Gentlemen Decoction) or Wu Jun Zi Jian (Five Gentimen Decoction) are appropriate. For deficiency in the Yin aspect, San Yin Jian (Three Yin Decoction), Wu Yin Jian (Five Yin Decoction), Da Ying Jian (Great Camp Decoction), or Xiao Ying Jian (Small Camp Decoction) are suitable. If the Middle Qi of the Spleen and Stomach is injured, Li Zhong Tang (Regulate the Middle Decoction) or Yang Zhong Jian (Nourish the Middle Decoction) are indicated. If both Qi and Blood are deficient, Wu Fu Yin (Five Blessings Drink), Ba Zhen Tang (Eight Treasures Decoction), or Shi Quan Da Bu Tang (Ten Complete Great Tonifying Decoction) are recommended.
One: When alternating chills and fever result from overexertion, irregular hunger, or satiety, it is because during hunger, the Qi of the Zang organs becomes weak, and during exertion, the Cou Li (pores and interstitial spaces) open. When the Cou Li are open, pathogens easily invade; when Zang Qi is weak, pathogens easily enter. Therefore, those who do not exercise caution regarding dietary intake and overexertion often suffer from symptoms such as headache, fever, and aversion to cold. Although these are attributed to internal injury, they actually involve external invasion; although there is external invasion, the root lies in internal injury. Thus, Li Dongyuan formulated Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction), using Ren Shen (Ginseng Root), [Original text missing character, typically Huang Qi], Dang Gui (Angelica Sinensis Root), Bai Zhu (Atractylodes Macrocephala Rhizome), augmented with Sheng Ma (Cimicifugae Rhizome) and Chai Hu (Bupleuri Radix), to assist the growth-promoting Qi. This causes Stomach Qi to ascend, thereby restoring Qi to the Middle Jiao and allowing Yang to reach the exterior. This is indeed an excellent method of harmonizing. However, nowadays, cases where overexertion damages Yin and affects Essence and Blood are particularly common; thus, herbs like Ren Shen and Bai Zhu may sometimes be unsuitable. I have therefore newly formulated Bu Yin Yi Qi Jian (Nourish Yin and Augment Qi Decoction). For cases where Yang is deficient below, Kidney Water is insufficient to generate sweat, and pathogens remain unresolved, this formula is superior. I have written treatises on three formulas for treating the Spleen and on Bu Zhong Yi Qi Tang, which can be found in the subsequent Dietary Section for reference.
One: When overexertion leads to pathogenic invasion resulting in Shang Han (Cold Damage), fever, headache, and body pain, if the pulse is tight and pathogens are abundant, dispersing and resolving methods must necessarily be employed. If the underlying deficiency is not severe but the exterior pathogens remain unresolved, Zheng Chai Hu Yin (Correct Bupleurum Drink) is appropriate. If external pathogens are combined with Fire, Yi Chai Hu Yin (First Bupleurum Drink) is used. If external pathogens are combined with Cold, Er Chai Hu Yin (Second Bupleurum Drink) is used. If Qi and Blood are slightly deficient, San Chai Hu Yin (Third Bupleurum Drink) or Si Chai Hu Yin (Fourth Bupleurum Drink) are used. In cases of severe deficiency where pathogens are difficult to resolve, Li Yin Jian (Regulate Yin Decoction) or Da Wen Zhong Yin (Great Warm the Middle Decoction) are indicated, and delay is inadvisable.
One: During the hot summer season, whether traveling on roads or working in fields, excessive overexhaustion in individuals with weak constitutions makes them most susceptible to Summerheat Injury. This also falls under the category of overexertion; detailed discussions on treatment can be found in the Summerheat Syndrome section under the Yang Summerheat article.
