此谓病已间，五脏尚虚，客邪未散，真气不复，故旦暮犹有余热如疟状。此非真实，但
客热也。
此谓经发汗、吐、下以后，腑脏空虚，津液竭绝，肾家有余热，故渴。
夫卫气昼行于阳，夜行于阴。阴主夜，夜主卧，谓阳气尽，阴气盛，则目瞑矣。今热气
未散，与诸阳并，所以阳独盛，阴偏虚，虽复病后，仍不得眠者，阴气未复于本故也。
其人血气先虚，复为虚邪所中，发汗、吐、下之后，经络损伤，阴阳竭绝，热邪始散，
真气尚少，五脏犹虚，谷神未复，无津液以荣养，故虚羸而生病焉。
此由阳明太阴受病，被下之后，其热已除，而脾胃为之虚冷，谷气未复，故不能食也。
夫诸阳在表，阳气虚则自汗。心主于汗，心脏偏虚，故其液妄出也。
夫人先瘀结在内，因伤寒病，若热搏于久瘀，则发热如狂；若有寒，则小腹满，小便反
利，此为血瘀。宜下之。其脉沉结者，血证谛也。
肝开窍于目。肝气虚，热乘虚上冲于目，故目赤痛；重者生疮翳、白膜、 肉。
这是由于大肠偏于虚弱，毒热之气冲犯肛门，导致下部突然疼痛，严重的如同鸟啄一般。
这指的是疾病已经缓解，但五脏仍然虚弱，外来的邪气尚未消散，真气未能恢复，所以早晚仍有类似疟疾的余热症状。这并不是真正的实证发热，只是客居的热邪罢了。
这指的是经过发汗、催吐、泻下等治法之后，脏腑空虚，津液枯竭，肾脏有余热，因此出现口渴。
卫气白天运行于阳分，夜晚运行于阴分。阴主夜间，夜间主睡眠，当阳气耗尽、阴气旺盛时，眼睛就会闭合入睡。现在热气尚未消散，与诸阳经之气相并，导致阳气独盛，阴气偏虚，虽然病后身体虚弱，仍然无法入睡，是因为阴气未能恢复到本源状态。
这个人的气血先前就虚弱，又遭受虚邪侵袭，在发汗、催吐、泻下之后，经络受损，阴阳之气衰竭，热邪刚刚散去，真气尚且稀少，五脏依然虚弱，谷气（脾胃运化功能）未恢复，没有津液来濡养身体，所以身体消瘦虚弱而生病。
这是由于阳明经和太阴经受病，被使用泻下法治疗后，体内的热邪已经清除，但脾胃变得虚冷，谷气未恢复，所以不能进食。
所有的阳经都在体表，阳气虚弱就会导致自汗。心主管汗液，心脏偏于虚弱，所以津液会妄行流出。
如果人体内部先有瘀血结聚，因患伤寒病，若热邪搏结于久存的瘀血上，就会出现发热如狂的症状；如果有寒邪，则小腹胀满，小便反而通畅，这是血瘀证。适宜使用攻下法治疗。如果脉象沉结，则是血证的确凿证据。
肝开窍于目。肝气虚弱，热邪乘虚上行冲击眼部，导致眼睛发红疼痛；严重的会长出疮疡、翳膜、白膜或息肉。
这是由于热毒之气从体内发出，沿着经络攻击手足部位。人体的五脏六腑的井穴、荥穴、俞穴，都出于手足指端，所以毒气从脏腑发出。
如果人体阴阳俱虚，湿毒之气与风热相互搏结，导致营卫运行涩滞，营卫涩滞则血气不能流通，血气不流通则邪热导致壅塞，随着经络所生之处形成流肿。
This is due to the large intestine being deficient, with toxic heat qi rushing against the anus, causing sudden pain in the lower part, and in severe cases, pain like bird pecking.
This refers to a condition where the illness has alleviated, but the five zang organs remain deficient, the exogenous pathogenic factors have not yet dispersed, and the true qi has not recovered; therefore, there remains residual heat resembling malaria in the morning and evening. This is not a genuine excess heat, but merely an invading heat pathogen.
This refers to a state after sweating, vomiting, or purging therapies, where the fu and zang organs are empty, body fluids are exhausted, and there is residual heat in the kidney, leading to thirst.
Wei qi (Defensive Qi) travels through the yang aspects during the day and the yin aspects at night. Yin governs the night, and night governs sleep; when yang qi is exhausted and yin qi is abundant, the eyes close for sleep. Now, since the heat pathogen has not yet dispersed and merges with the various yang meridians, yang becomes excessively strong while yin becomes relatively deficient. Although the patient is weak post-illness, they still cannot sleep because yin qi has not returned to its original state.
The person's blood and qi were previously deficient, and they were subsequently struck by deficient pathogens. After sweating, vomiting, or purging, the meridians and collaterals were damaged, yin and yang qi were exhausted, and the heat pathogen had just dispersed. The true qi was still scarce, the five zang organs remained deficient, the grain spirit (Spleen/Stomach digestive function) had not recovered, and there were no body fluids to nourish the body, resulting in emaciation and illness.
This is because the Yangming and Taiyin meridians were affected. After purging therapy, the internal heat was cleared, but the Spleen and Stomach became deficient and cold, and the grain qi had not recovered, leading to an inability to eat.
All yang meridians are on the exterior. When yang qi is deficient, spontaneous sweating occurs. The Heart governs sweat; if the Heart is deficient, body fluids will flow out recklessly.
If there is initially blood stasis accumulation internally, and upon contracting a cold damage disease, heat pathogens clash with long-standing blood stasis, fever and mania-like symptoms occur; if cold pathogens are present, there is fullness in the lower abdomen, and urination is surprisingly free, indicating blood stasis. Purging therapy is appropriate. A deep and knotted pulse confirms the diagnosis of blood stasis.
The Liver opens into the eyes. When Liver qi is deficient, heat pathogens rush upward into the eyes due to deficiency, causing redness and pain in the eyes; in severe cases, sores, nebulae, white membranes, or fleshy growths may develop.
This is due to toxic heat qi emerging from within and attacking the hands and feet along the meridians. The Jing-Well, Ying-Spring, and Shu-Stream acupoints of the five zang and six fu organs all emerge from the fingers and toes; thus, toxins exit from the zang and fu organs.
When both yin and yang are deficient, damp-toxic qi clashes with wind-heat, causing Wei and Ying qi to become stagnant. When Wei and Ying qi are stagnant, blood and qi do not circulate freely; when blood and qi do not circulate, pathogenic heat causes obstruction, leading to flowing swellings along the affected meridians.
