病在中气之虚也，其症小便自利，脉息无力，神思困倦，言语轻微，或怔忡眩晕，畏寒
少食
，四肢不举，或大便不实，小便如膏。得之内伤劳役，饥饱失时，中气大伤，脾不化血，而
脾土之色自见于外。《金匮》云∶男子痿黄，小便自利，当与虚劳小建中汤。又《略例》云
∶内伤劳役，饮食失节，中州变寒之病而生黄者，非伤寒坏症，而只用建中、理中、大建中
足矣。不必用茵陈也。
即伤寒症也。东垣云∶伤寒当汗不汗，即生黄。邪在表者，宜急汗之，在表之里，宜渗
利之
；在半表半里，宜和解之；在里者，宜急下之。在表者必发热身痛，在里者必烦热而渴，若
阳明热邪内郁者，必痞结胀闷也。

这是中气虚弱的病证，其症状表现为小便通畅自如，脉象微弱无力，精神疲倦困乏，说话声音低微，或者出现心悸、头晕目眩，怕冷，食欲减退，四肢无力抬举，或者大便稀溏不成形，小便浑浊如膏脂。此病多因内伤劳役过度，饮食饥饱无常，导致中气严重受损，脾脏无法化生血液，从而脾土的本色显露于体表。《金匮要略》中说：男子面色萎黄，小便通畅，应当给予虚劳小建中汤治疗。另外《医宗必读·略例》中说：因内伤劳役，饮食不节制，导致中焦脾胃变寒而产生的发黄病症，并非伤寒误治后的坏病，只需使用建中汤、理中汤或大建中汤即可。不需要使用茵陈。
这指的是伤寒病症。李东垣说：伤寒症应当发汗却未发汗，就会发生发黄。邪气在表位的，应当紧急发汗；邪气在表之里的（半表半里之间），应当用渗湿利水的方法；在半表半里的，应当用和解的方法；邪气在里的，应当紧急攻下。邪气在表的必然伴有发热和身体疼痛，邪气在里的必然伴有烦热和口渴，如果是阳明经的热邪内郁，必然会出现痞塞、结聚、胀闷的症状。

This is a syndrome of deficiency in the Middle Qi (Middle Jiao Qi). The symptoms include free urination, a weak and powerless pulse, mental fatigue and lassitude, faint speech, or palpitations and dizziness, aversion to cold, poor appetite, inability to lift the limbs, loose stools, or urine that resembles paste. This condition arises from internal injury due to overwork, irregular eating habits leading to severe damage to the Middle Qi. The Spleen fails to transform blood, causing the color of Spleen Earth to manifest externally. *Jin Gui Yao Lue* states: "In men with sallow complexion and free urination, one should administer Xiao Jian Zhong Tang for deficiency consumption." Furthermore, *Lue Li* states: "Jaundice arising from internal injury, overwork, and dietary irregularities causing cold transformation in the Middle Jiao is not a deteriorated syndrome from Taiyang disease; it suffices to use only Jian Zhong Tang, Li Zhong Tang, or Da Jian Zhong Tang. Yin Chen is not necessary."
This refers to Shaoyang disease. Dong Yuan stated: "If Shaoyang disease requires sweating but does not sweat, jaundice will develop." If the pathogen is at the Exterior level, urgent sweating is indicated; if it is between the Exterior and Interior, diuresis and leaching out dampness are indicated; if it is at the Half-Exterior Half-Interior level, harmonization is indicated; if it is at the Interior level, urgent purgation is indicated. Pathogens at the Exterior must present with fever and body pain; pathogens at the Interior must present with vexing heat and thirst; if Yangming heat pathogen is internally constrained, there must be epigastric fullness, obstruction, distension, and oppression.
