人脏腑虚实不调，则生于客热，表有风湿，与热气相搏，则身体生疮，痒痛而脓汁出，
甚者一瘥一剧，此风热所为也。
上实下虚，热气内盛，熏于咽喉，故生疮也。
夫经发汗，汗出多则津液少，津液少则胃干结，热在胃，所以大便不通。又有腑脏自生
于热者，此由三焦痞隔，脾胃不和，蓄热在内，亦大便不通也。
热气攻于肠胃，则谷气衰，所以三虫动作，食人五脏及下部，重者肛烂见腑脏。
肝脏开窍于目，肝气虚，热毒乘虚则上冲于目，重者生疮翳及赤白膜也。
夫热病毒攻手足，及人五脏六腑井荥俞皆出于手足指，今毒瓦斯从腑脏而出，循于经络，
攻于手足，故手足指皆肿赤 痛也。
胃内有热，则谷气不和，新谷入胃，与热气相搏，胃气不平，故呕。或吐下以后，脏虚
亦令呕也。
伏热在胃，则令人胸满，胸满则气逆，气逆则哕。若大下以后，饮水多，胃内虚冷，亦
令哕也。
人的脏腑虚实不调，就会产生客热（外来的热邪），体表有风湿之邪，与热气相互搏结，就会导致身体生疮，瘙痒疼痛并流出脓汁，严重时病情反复，时好时坏，这是风热邪气所致。
这是由于脾脏有热，热气上冲至胸膈以上部位（上焦），所以口腔内生疮。
上部实而下部虚，体内热气旺盛，熏蒸咽喉，所以咽喉生疮。
经过发汗治疗后，出汗过多导致津液减少，津液少则胃中干燥结滞，热邪在胃中，所以大便不通畅。又有脏腑自身产生热邪的情况，这是由于三焦气机痞塞阻隔，脾胃不和，热量蓄积在体内，也会导致大便不通。
热邪在膀胱，流注到小肠，热势亢盛则导致脾胃干燥，津液减少，所以小便不通畅。
热邪侵袭肠胃，胃气虚弱则排泄出赤黄色的汁液，夹杂毒邪则形成脓血。
热邪侵袭肠胃，则水谷精微之气衰弱，所以体内的三种寄生虫（蛔虫、蛲虫、姜片虫等）妄动，侵蚀人的五脏及下部器官，严重的会导致肛门腐烂甚至露出内脏。
肝脏的开窍在于眼睛，肝气虚弱，热毒乘虚而上冲于目，严重的会长出疮疡、翳膜以及红白色的薄膜。
热毒邪气侵袭手足，且人体五脏六腑的井穴、荥穴、俞穴都分布于手足指端，现在毒气从脏腑发出，沿着经络运行，侵袭手足，所以手足指头都会肿胀、发红、疼痛。
胃内有热，则水谷精微之气不和，新摄入的食物进入胃中，与热气相互搏结，胃气不平和顺，所以发生呕吐。或者在吐泻之后，脏腑虚弱，也会导致呕吐。
伏留的热邪在胃中，会使人胸部胀满，胸部胀满则气机上逆，气机上逆就会发生呃逆（打嗝）。如果在剧烈泻下之后，饮水过多，胃内虚冷，也会导致呃逆。
When the deficiency and excess of the internal organs are not harmonious, external heat (Ke Re) arises. If wind-dampness exists on the exterior and contends with heat qi, sores will appear on the body, accompanied by itching, pain, and discharge of pus. In severe cases, the condition fluctuates between remission and exacerbation; this is caused by wind-heat pathogenic factors.
This occurs due to heat in the Spleen organ, which rushes upward to the Upper Jiao (the upper burner, encompassing the heart and lungs), resulting in sores in the mouth.
With excess in the upper part and deficiency in the lower part, abundant internal heat steams and scorches the throat, causing sores there.
After diaphoresis (sweating therapy), excessive sweating leads to a scarcity of Body Fluids (Jin Ye). A shortage of fluids causes dryness and stagnation in the Stomach, with heat residing within, thus leading to constipation. Additionally, some cases involve heat generated spontaneously by the internal organs; this stems from obstruction in the San Jiao (Triple Burner) and disharmony between the Spleen and Stomach, where heat accumulates internally, also resulting in constipation.
Heat in the Bladder flows into the Small Intestine. When heat is excessive, it dries the Spleen and Stomach and depletes fluids, leading to urinary retention.
Heat pathogens attack the intestines and stomach. If the Stomach Qi is deficient, red-yellow fluid is discharged; if mixed with toxins, it becomes pus and blood.
Heat pathogens attacking the intestines and stomach cause the decline of Gu Qi (Grain Qi/nutritive energy derived from food). Consequently, the "Three Worms" (intestinal parasites) become active, devouring the five zang organs and the lower orifices. In severe cases, anal erosion occurs, exposing the viscera.
The Liver opens into the eyes. When Liver Qi is deficient, heat-toxins take advantage of the deficiency to rush upward to the eyes. In severe cases, this results in sores, nebulae (corneal opacities), and red-white membranes.
Heat-toxin pathogens attack the hands and feet. The Jing-River points (Jing-Xue, Ying-Xue, Shu-Xue) of the five zang and six fu organs all emerge from the fingers and toes. Now, as toxin qi exits from the viscera and follows the meridians to attack the hands and feet, the fingertips become swollen, red, and painful.
Heat within the Stomach disrupts the harmony of Grain Qi. When new food enters the Stomach, it contends with the existing heat, disturbing Stomach Qi and causing vomiting. Alternatively, after vomiting or purging, visceral deficiency can also lead to vomiting.
Latent heat in the Stomach causes chest fullness. Chest fullness leads to rebellious Qi, and rebellious Qi causes hiccups (Yue). If, following severe purging, large amounts of water are consumed, the coldness and deficiency in the Stomach can also induce hiccups.
This is due to deficient heat in the five zang organs and disharmony between the Spleen and Stomach, leading to exhaustion and scarcity of fluids, resulting in a dry mouth.
This is caused by heat injuring the Heart. The Heart governs Blood, and the Lung governs Qi, opening into the nose. When evil heat combines with Blood and Qi, epistaxis (nosebleed) occurs. Epistaxis refers to blood flowing from the nasal cavity.
When a heat disease has just healed, fluids have not yet recovered, and Qi and Blood remain deficient. If one engages in labor too early, physical exertion generates heat. This heat takes advantage of the deficiency to re-enter the meridians, causing the recurrence of the disease.
