此由脾胃大热，热伤于心，心主于血，热气盛，故发黄而动血，故因名为发血。
黄病后，小便涩，兼石淋，发黄胆，此皆由蓄热所为。热流小肠，小便涩少而痛，下物
如沙石也。
黄胆之病，此由酒食过度，腑脏不和，水谷相并，积于脾胃，复为风湿所搏，瘀结不散
，热气郁蒸，故食已如饥，令身体面目爪甲及小便尽黄，而欲安卧。
若身脉多赤，多黑、多青皆见者，必寒热身痛。面色微黄，齿垢黄，爪甲上黄，黄胆也
疸而渴者，其病难治；疸而不渴，其病可治。发于阴部，其人必呕；发于阳部，其人振
夫虚劳之人，若饮酒多，进谷少者，则胃内生热。因大醉当风入水，则身目发黄，心中
懊痛，足胫满，小便黄，面发赤斑。若下之，久久变为黑疸，面目黑，心中如啖蒜齑
状，大便正黑，皮肤爪之不仁。其脉浮弱，故知之。
酒疸，心中热，欲呕者，当吐之则愈。其小便不利，其候当心中热，足不热，是其证明
若腹满欲吐，鼻燥，其脉浮，先吐之，沉弦，先下之。
凡是先前患有风湿病，又遭遇冷气侵袭并与之相搏结，就会导致全身疼痛，出现发热并且身体发黄的症状。
这是由于脾胃有大热，热邪损伤了心脏；心主司血液运行，当热气亢盛时，就会使身体发黄并导致出血，因此这种病症被称为“发血”。
这是由于瘀滞的热邪停留在脾胃之中，进而导致身体发黄；如果夹杂毒邪则会出现下痢症状，因此这种病症被称为“发痢”。
这种病症是因为热邪损伤了心脏，心主司血液，热势亢盛则血液随大便排出体外，这种病症称为“血痔”。
所有的黄疸病都是由大热引起的。在热势亢盛的时候，必须服用寒凉药物，但如果寒凉药物过多，就会触动体内原有的积块癖疾。
患黄疸病后，如果出现小便涩滞不畅，兼有石淋（尿路结石），以及发黄胆等症状，这都是由蓄积的热邪所致。热邪流注于小肠，导致小便涩滞、量少且疼痛，排出的物体像沙石一样。
在黄疸病经过催吐或泻下治疗后，胃气变得虚弱寒冷，如果患者原本就有寒饮停聚的宿疾，就会引发呕吐。
黄疸病的成因，是由于饮酒和饮食过度，导致脏腑功能不和，水谷之气相互混杂，积聚在脾胃之中，再加上受到风湿邪气的搏结，瘀结不散，热气郁蒸，所以会出现吃完饭后感觉饥饿，身体、面目、爪甲以及小便全部发黄，并且想要安静躺卧的症状。
如果身上的脉象呈现多赤色、多黑色、多青色等颜色交错出现的现象，必定伴有忽冷忽热和身体疼痛。面色微微发黄，牙齿上有黄色垢腻，爪甲上发黄，这就是黄疸病。黄疸病如果伴有口渴，说明病情难治；如果不口渴，说明病情容易治愈。病发于阴部的人，一定会呕吐；病发于阳部的人，会出现寒战
虚劳体质的人，如果饮酒过多而进食谷物较少，胃中就会产生内热。如果在醉酒之后迎风受寒或进入水中，就会导致身体和眼睛发黄，心中感到烦闷疼痛，小腿肿胀满急，小便发黄，面部出现红色斑点。如果使用攻下法治疗，久而久之会转变为黑疸，表现为面目发黑，心中感觉像吃了蒜泥一样的辛辣刺痛感，大便完全变黑，皮肤麻木不仁。通过诊察脉象浮弱，就可以知道这是黑疸。
酒疸病患者，如果心中烦热且有想呕吐的感觉，应当使用涌吐法治疗，呕吐后痊愈。如果小便不利，其证候表现为心中烦热但脚部不热，这是其确切的证明。
Any person who previously suffered from wind-dampness and then encountered cold qi, which fought with the pathogenic factors, will experience pain throughout the body, fever, and yellowing of the body.
This is due to excessive heat in the Spleen and Stomach; the heat injures the Heart. The Heart governs blood. When heat qi is exuberant, it causes yellowing of the body and disturbs the blood (bleeding), hence this condition is named "Fa Xue" (Bleeding Eruption).
This is caused by stagnant heat residing in the Spleen and Stomach, leading to yellowing of the body. If it is complicated by toxins, it results in dysentery, hence this condition is named "Fa Li" (Dysentery Eruption).
This disease arises because heat injures the Heart, and the Heart governs blood. When heat is exuberant, blood follows the stool downward, a condition named "Xue Zhi" (Hemorrhoidal Bleeding).
All jaundice diseases are caused by excessive heat. During times of exuberant heat, one must take cooling medicines. However, if too many cooling medicines are taken, they may stir up old accumulations or masses (Pi Ji).
After suffering from jaundice, if there is difficult and painful urination accompanied by stone strangury (Shi Lin) and yellowing of the gallbladder, these are all caused by accumulated heat. Heat flows into the Small Intestine, causing difficult, scanty, and painful urination, with discharge resembling sand and stones.
After vomiting and purging for jaundice, the Stomach Qi becomes deficient and cold. If the person has a chronic condition involving cold fluid retention, vomiting will occur.
The disease of Jaundice (Dan Huang) is caused by excessive consumption of alcohol and food, leading to disharmony of the Fu and Zang organs. Water and grain mix together and accumulate in the Spleen and Stomach. Combined with the struggle against wind-dampness, the stagnation does not disperse. Heat qi stagnates and steams, causing the sensation of hunger after eating, yellowing of the body, face, nails, and urine, and a desire to lie still.
If the pulses on the body show mixed colors—predominantly red, black, or blue—it indicates alternating chills and fever along with body pain. A slightly yellow complexion, yellow dental plaque, and yellow nails indicate Dan Huang (Jaundice). If Dan Huang is accompanied by thirst, the disease is difficult to treat; if not accompanied by thirst, it is treatable. If the disease manifests in Yin regions, the person will certainly vomit; if it manifests in Yang regions, the person will experience shivering
In persons with deficiency consumptive diseases, if they drink much alcohol but eat little grain, internal heat generates in the Stomach. If they enter water or are exposed to wind while heavily intoxicated, the body and eyes turn yellow, the heart feels vexed and painful, the calves become full and swollen, the urine turns yellow, and red spots appear on the face. If treated with purgatives, over time it transforms into Black Dan (Hei Dan), characterized by a black face and eyes, a sensation in the heart as if eating minced garlic, completely black stools, and skin that is numb and insensitive to scratching. This can be known by a floating and weak pulse.
For Jiu Dan (Alcohol Jaundice), if the patient feels heat in the heart and desires to vomit, inducing vomiting will lead to recovery. If there is difficulty in urination, the symptom profile shows heat in the heart but no heat in the feet; this confirms the diagnosis.
If there is abdominal fullness, a desire to vomit, dry nose, and a floating pulse, induce vomiting first. If the pulse is deep and wiry, purge first.
