邵评∶发黄有因热因湿之不同。热属阳明而色明亮者。阳黄也。湿属太阴而色晦暗者。
阴黄也。故治发黄。当辨其湿热阴阳之不同。
太阳蓄血亦发黄。但以小便不利。为湿热发黄。小便自利。为蓄血发黄也。
邵评∶蓄血有身黄一症。非蓄血必发黄也。此以发黄之小便不利。借证蓄血之小便自利。非以蓄血发黄
二症对勘也。其实以湿热之小便不利。借证蓄血之小便自利耳。
又评∶蓄血有身黄者。非发黄因于蓄血也。不可以湿热发黄与蓄血发黄对列。

邵评∶此阳明湿热发黄之症。但头汗而身无汗。郁热上熏而邪不外达也。小便不利。其热又不得下泄。
而又渴欲饮水。则热之蓄于内者方炽。而湿之引于外者无已。湿与热合。瘀郁不解。未能表达里通。

邵评∶阴黄阳绝则死。阳黄阴竭亦死。
湿热邪气都严重的时候，就会发生发黄。阳明经热邪偏胜的，黄色像橘子皮那样鲜明光亮；太阴经湿邪偏胜的，黄色像被烟熏过那样晦暗无光。
邵评：发黄有因热邪和因湿邪的不同。热邪属于阳明经，颜色明亮的是阳黄。湿邪属于太阴经，颜色晦暗的是阴黄。所以治疗发黄，应当辨别其湿热、阴阳的不同。
太阳经蓄血证也会发黄，但通过小便是否通畅来区分：小便不利的是湿热发黄，小便自利（通畅）的是蓄血发黄。
邵评：蓄血证有身体发黄这一症状，但并非蓄血证一定会发黄。这里是用湿热发黄的小便不利，来反证蓄血证的小便自利，并不是将蓄血发黄这两个症状进行对勘比较。其实是用湿热导致的小便不利，来佐证蓄血证的小便自利罢了。
又评：蓄血证出现身黄，并不是因为蓄血导致的发黄。不能将湿热发黄与蓄血发黄并列看待。大概是因为发黄是由于外感则汗液不得排泄，内里则小便不利，导致湿邪和瘀热郁结而发黄。所以湿热发黄，小便不利；蓄血证不在气分，且小便自利，那么体内的湿邪和瘀热已经得到外泄，怎么能发黄呢？要知道蓄血与发黄，没有同时并见的道理。热邪在膀胱，就会发黄；血液凝结在膀胱，就会形成蓄血。病在气分还是在血分，是有形还是无形，截然相反。如果确实是太阳经发黄，却使用治疗蓄血的峻猛方剂抵当汤服用，那么前阴会出血如泉涌，立刻死亡。蓄血证也谈论发黄，这种误解不是小事，所以特别加以辨析。
太阳病失于解表，瘀热留在体内，表实无汗，小便不利，身体发黄的，用麻黄连翘赤小豆汤主治，使黄疸从汗液排出而解除。
邵评：太阳病失于发表，外面无汗出，内里小便不利，热邪入里而不能向外发散，称为瘀热。热邪蒸腾导致发黄，这是热邪瘀结但未成实证的病症。因为它既有表证又有里证，所以用麻黄、杏仁、生姜的发汗散表作用，以及赤小豆、梓白皮、连翘根的苦寒清热利水作用。大概因为发黄是热邪瘀结但未成实证，所以以发汗清利，双解表里作为治疗方法。
阳明病，遍身无汗，只有头部出汗，小便不利，口渴想喝水的，这是热邪不得宣泄，瘀积在体内而发黄，用茵陈蒿汤主治，使黄疸从大便排出而解除。
邵评：这是阳明经湿热发黄的病症。只有头部出汗而身上无汗，是郁热上熏而邪气不能向外达出。小便不利，热邪又不能向下排泄，而又口渴想喝水，说明热邪蓄积在内正炽盛，而湿邪牵引在外没有止境。湿与热结合，瘀郁不解，不能通达表和里，势必蒸发成为黄疸。用茵陈蒿汤苦寒通泄，使体内瘀积的湿热向下趋行，那么黄疸就从大便排出而下解。这条《伤寒论》原文中有“腹满”一症，是因为邪气不能向外泄下通，郁热发黄，邪气深入里部而导致腹满，这是阳明热实证的病症，所以在方中使用大黄清除湿热并攻下里实。
太阴病小便不利，湿土被热邪蒸腾而发黄的，用茵陈五苓散主治，使黄疸从小便排出而解除。
邵评：太阴经湿气潜伏，不从小便向下排泄，遏阻在内部蒸腾热气而发黄，这是太阴湿热症。用五苓散宣化膀胱的气机以利小便，加入茵陈以清渗湿热。大概太阴经湿郁蒸热而发黄，热邪未成实证，应当宣通气化，使邪气从小便排出而解除。
《瘟疫论》说：疫邪传入里部，遗留下热邪在下焦，小便不利，邪气没有输泄途径，经气郁滞，传变为疸病，身体眼睛都像金子一样黄，适宜用茵陈蒿汤。如果用茵陈五苓散，不但不能退黄，就连小便也难以通利。这是因为胃家移热所致，所以大黄有特殊的功效。
邵评：瘟疫湿浊之邪传入阳明，热邪在中下二焦，结聚而成实证，气机不宣通，郁结而发黄。这是阳黄实证热邪，用茵陈蒿汤攻下热实。大概疫邪热邪入里，阳明胃家热而成实，所以用茵陈蒿汤攻下热实。这与上一条湿热发黄、热邪未成实证的情况不同。
邵评：这是阳明经的病症，表无邪气郁结，里未成实证，所以说没有表里症。乃是身体发热发黄，热邪瘀结在阳明经。所以只治疗以清热为主。
凡是发黄，热多则脉必数急，全身不痛，以解毒为主；湿多则脉必缓怠，全身尽痛，以渗湿为主。
邵评：热盛于阳明，蒸腾郁结而发黄，脉数而身体不痛的是阳黄，用清热解毒法治疗。太阴湿邪偏胜，阻滞气机而发黄，脉缓身体疼痛，湿邪进入经络，成为阴黄，以渗湿行气法为主。只有热黄脉数属于阳明，湿黄脉缓属于太阴。
邵评：这是阳明经瘀热发黄的治法。方中宜再加泽兰、红曲以消除瘀血。以上论述的是阳黄症。
发黄后出汗但身体寒冷，脉象沉迟，小便不利，口不渴的，是阴黄症。小便不利的，用五苓散加干姜、茵陈；大小便都通畅的，用理中汤加茵陈。
伤寒遇到辰、戌、丑、未年，太阳、太阴司天，医生用药寒凉太过，往往会有阴黄的病症。脉象沉迟，肢体冷而发黄，适宜用理中汤加茵陈主治。小便不利，理中汤加茯苓、猪苓、官桂；呕吐的，理中汤合二陈汤加生姜。如果天空久雨不停，湿令大行，又应当用理中汤合平胃散为妥当。严重的加附子。
邵评：寒水湿土当令之年，如果其人阳气本虚，偶尔受湿邪，医生过用寒凉药，损伤其中焦阳气，而形成阴黄症。所见脉症，全是阴寒之象，与阳黄的热实证大相径庭。用理中汤加茵陈，温运中焦阳气而化湿。阴寒严重的，当加附子以扶助阳气、泄除浊邪。如果中焦阳气虚弱，寒湿内伏，阳气不得宣化，而小便不利，加茯苓、桂枝以通阳利水。呕吐的，是胃虚有寒痰，合二陈汤加生姜，以调和胃气而化痰饮。只有久雨湿盛，阴浊之气太甚，脾胃中土受到损害，所以用理中汤温运中宫，合平胃散除湿化邪。这是脾阳虚弱，寒湿内伏而成阴黄，治疗以温中化湿为主。
脾绝出现的类似发黄的病症，全身尽黄，寸口无脉，鼻中出冷气，摇头直视，口周发黑，形体如烟煤般黑褐，这是脾家真气断绝，不是发黄。第一书说：胆气绝，则面色黄；脾气绝，则身体黄。这些都是黄如土色，干枯无神气的表现。
邵评：脾属阴土，黄色是土的本色。脾阳衰乏，阳气不运行，所以寸口无脉。阳气微弱欲绝，则气冷不温暖。所见的各种症状，纯粹是一派阴浊作祟，微弱的阳气将要被埋没，脾的真气宣告断绝，土的本色毫无保留地显露在外现。所以全身尽见黄色。这是脏气绝的病症，与发黄症有外邪的情况各不相同。
When damp-heat pathogens are both severe, jaundice (yellowing of the skin and eyes) occurs. If heat is predominant in the Yangming channel, the yellow color is bright and lustrous like an orange peel; if dampness is predominant in the Taiyin channel, the yellow color is dull and dark like something smoked.
Shao's Commentary: Jaundice differs depending on whether it is caused by heat or dampness. Heat belongs to the Yangming channel, and a bright color indicates Yang Jaundice. Dampness belongs to the Taiyin channel, and a dark color indicates Yin Jaundice. Therefore, when treating jaundice, one must distinguish between the differences in damp-heat and yin-yang.
Blood stasis accumulation in the Taiyang channel can also cause jaundice, but it is distinguished by urination: urinary difficulty indicates damp-heat jaundice, while spontaneous free urination indicates blood stasis jaundice.
Shao's Commentary: Blood stasis syndrome has the symptom of body yellowing, but blood stasis does not necessarily cause jaundice. Here, the urinary difficulty of damp-heat jaundice is used to contrast with the spontaneous free urination of blood stasis, rather than comparing the two symptoms of "blood stasis jaundice" directly. In essence, it uses the urinary difficulty caused by damp-heat to corroborate the spontaneous free urination of blood stasis.
Further Commentary: The body yellowing seen in blood stasis is not jaundice caused by blood stasis. One should not list damp-heat jaundice and blood stasis jaundice side by side. Generally, jaundice arises because external pathogens prevent sweat excretion, and internally, urinary difficulty leads to the stagnation of dampness and stagnant heat, which condense to form yellow. Thus, in damp-heat jaundice, there is urinary difficulty. Blood stasis resides in the blood level, not the qi level, and features spontaneous free urination, meaning internal dampness and stagnant heat have been externally discharged; how could jaundice form? It must be understood that blood stasis and jaundice do not coexist. Heat in the Bladder causes jaundice; blood coagulation in the Bladder causes blood stasis. Pathology in the qi level versus the blood level, and有形 (solid/form) versus 无形 (formless), are截然 opposite (completely distinct). If Taiyang jaundice were mistakenly treated with the harsh formula Didang Tang (Cassia Twig and Fermented Soybean Decoction) for blood stasis, bleeding from the anterior orifice would gush like a spring, leading to immediate death. Discussing jaundice in the context of blood stasis is a significant error, hence this clarification.
The pulse in blood stasis jaundice is deep, fine, and knotted. The pulse in damp-heat jaundice is floating, slippery, and rapid.
Shao's Commentary: This distinguishes the pulse presentations of blood stasis jaundice versus damp-heat jaundice.
In blood stasis jaundice, bowel movements are smooth and clear. In damp-heat jaundice, stool is yellow and turbid.
Shao's Commentary: This differentiates jaundice from blood stasis based on whether the stool is yellow/turbid or clear/smooth.
If Taiyang disease fails to resolve the exterior, causing stagnant heat to remain inside, with exterior excess, no sweating, urinary difficulty, and body yellowing, Mahuang Lianqiao Xiaodou Tang (Ephedra, Forsythia, and Red Bean Decoction) is the primary treatment, allowing the jaundice to resolve through sweating.
Shao's Commentary: Failure to release the exterior in Taiyang disease results in no external sweat and internal urinary difficulty. Heat enters the interior without dispersing outward, termed stagnant heat. Heat steaming causes jaundice; this is a condition where heat is stagnant but not yet solidified. Since there are both exterior and interior signs, Mahuang, Xingren, and Shengjiang are used to induce sweating and disperse the exterior, while Chidou, Zibai Pi, and Lianqiao Gen are used for their bitter-cold properties to clear heat and promote diuresis. Because jaundice here involves heat stagnation without solidification, the treatment employs sweating and clearing/diuresis to simultaneously resolve the exterior and interior.
In Yangming disease, with generalized lack of sweat, only head sweating, urinary difficulty, and thirst desire for water, this indicates heat cannot vent, stagnates in the interior, and causes jaundice. Yinchen Hao Tang (Artemisiae Scopariae and Sorghum Decoction) is the primary treatment, allowing the jaundice to resolve through bowel movement.
Shao's Commentary: This describes Yangming damp-heat jaundice. Head sweating without body sweating indicates stagnant heat steaming upward while pathogens fail to reach the exterior. Urinary difficulty prevents heat from draining downward. Thirst indicates intense internal heat accumulation, while dampness persists externally. Dampness and heat combine, stagnating unresolved, unable to vent via the exterior or unblock the interior, inevitably evaporating into jaundice. Yinchen Hao Tang uses bitter-cold purgation to direct internal stagnant damp-heat downward, so jaundice exits via stool. The original Shanghan Lun text includes "abdominal fullness," indicating pathogens failed to vent downward, stagnant heat formed jaundice, and pathogens penetrated deeply causing abdominal fullness—a Yangming heat-excess syndrome. Thus, Dahuang is used in the formula to clear damp-heat and purge interior excess.
In Taiyin disease, with urinary difficulty, where damp-earth is steamed by heat causing jaundice, Yinchen Wuling San (Artemisiae Scopariae and Five-Ingredient Poria Powder) is the primary treatment, allowing jaundice to resolve through urination.
Shao's Commentary: Taiyin dampness lies dormant, failing to drain via urine, obstructing internally and steaming heat to cause jaundice; this is a Taiyin damp-heat syndrome. Wuling San promotes bladder qi transformation to aid urination, added with Yinchen to clear and leach damp-heat. Since Taiyin damp-stagnation steams heat to cause jaundice without solidification, promoting qi transformation allows pathogens to exit via urine.
Wenbing Tiao Bian states: When epidemic pathogens transmit to the interior, leaving heat in the Lower Jiao, urinary difficulty occurs, pathogens lack drainage, meridian qi stagnates, transforming into jaundice with body and eyes golden-yellow. Yinchens Hao Tang is appropriate. If Yinchen Wuling San is used, it will not only fail to reduce jaundice but also hinder urination. This is due to heat transferring to the Stomach home, where Dahuang has specific efficacy.
Shao's Commentary: Epidemic damp-turbid pathogens transmit to Yangming, with heat in the Middle and Lower Jiao, consolidating into excess, blocking qi flow, and stagnating into jaundice. This is Yang Jaundice excess-heat, treated with Yinchen Hao Tang to purge heat-excess. Epidemic heat entering the interior causes Yangming Stomach heat to become solid; thus, Yinchen Hao Tang purges heat-excess. This differs from the previous case of damp-heat jaundice where heat was not yet solid.
In Shanghan, if there is fever and jaundice without exterior or interior excess syndromes, Zhizi Bopi Tang (Gardeniae Cortex Phellodendri Decoction) is the primary treatment.
Shao's Commentary: This is a Yangming meridian syndrome. There is no exterior pathogen stagnation, nor interior excess formation, hence "no exterior-interior syndrome." Body heat and jaundice result from heat stagnating in the Yangming meridian. Treatment focuses solely on clearing heat.
Generally, in jaundice, if heat is predominant, the pulse is rapid, the body does not ache, and treatment prioritizes detoxification. If dampness is predominant, the pulse is slow, the whole body aches, and treatment prioritizes leaching dampness.
Shao's Commentary: Heat excess in Yangming steams and stagnates to cause jaundice; rapid pulse without body pain indicates Yang Jaundice, treated with heat-clearing and detoxification. Taiyin dampness excess blocks qi to cause jaundice; slow pulse with body pain indicates dampness entering meridians, forming Yin Jaundice, treated with damp-leaching and qi-moving methods. Only heat jaundice with rapid pulse belongs to Yangming; damp jaundice with slow pulse belongs to Taiyin.
Yangming jaundice with excessive heat and constipation of both bowels and bladder is treated with Yinchen Hao Tang.
Shao's Commentary: This is the standard method for Yangming heat-excess jaundice.
Taiyin jaundice with excessive dampness and urinary difficulty is treated with Yinchen Wuling San.
Shao's Commentary: This is the standard method for Taiyin damp-stagnation jaundice.
Body heat with jaundice, without exterior-interior syndromes, is treated with Zhizi Bipi Tang.
Shao's Commentary: This is the treatment for Yangming meridian stagnant-heat jaundice. Zelán and Hongqu should be added to the formula to resolve blood stasis. The above discusses Yang Jaundice syndromes.
Jaundice with sweating but cold body, deep-slow pulse, urinary difficulty, and no thirst is Yin Jaundice. With urinary difficulty, use Wuling San plus Ganjiang and Yinchen. With free urination and defecation, use Lizhong Tang plus Yinchen.
In Shanghan, during years governed by Chen, Xu, Chou, Wei, with Taiyang and Taiyin ruling the Heaven, physicians using excessive cold-cooling herbs often encounter Yin Jaundice. Pulse is deep-slow, limbs are cold, and jaundice appears; Lizhong Tang plus Yinchen is indicated. For urinary difficulty, add Lingzhi (Poria) and Guigui (Cinnamon Bark) to Lizhong Tang. For vomiting, combine Lizhong Tang with Erchen Tang and Shengjiang. If prolonged rain causes excessive dampness, combine Lizhong Tang with Pingwei San. Severe cases require adding Fuzi.
Shao's Commentary: In years of Cold-Water and Damp-Earth dominance, if the person has deficient Yang and contracts dampness, excessive use of cold herbs damages Middle Yang, forming Yin Jaundice. All observed pulses and symptoms are Yin-cold signs, vastly different from Yang Jaundice heat-excess. Lizhong Tang plus Yinchen warms and moves Middle Yang to transform dampness. For severe Yin-cold, add Fuzi to support Yang and drain turbidity. If Middle Yang is weak with internal cold-damp stagnation preventing Qi transformation and causing urinary difficulty, add Fuling and Guizhi to unblock Yang and promote diuresis. Vomiting indicates Stomach deficiency with cold-phlegm; combining Erchen Tang and Shengjiang harmonizes Stomach Qi and transforms phlegm-fluids. Prolonged rain causes excessive Yin-turbidity, damaging Spleen-Stomach Earth; thus, Lizhong Tang warms the Middle Palace, combined with Pingwei San to drain dampness. This is Yin Jaundice caused by Spleen Yang deficiency and internal cold-damp stagnation, treated primarily by warming the Middle and transforming dampness.
Spleen exhaustion mimicking jaundice presents as total body yellowing, absence of pulse at Cun Kou, cold air from nose, head shaking, fixed gaze, blackening around the mouth, and body resembling burnt coal smoke. This is the exhaustion of Spleen True Qi, not jaundice. The First Book states: Gallbladder Qi exhaustion causes facial yellowing; Spleen Qi exhaustion causes body yellowing. These present as yellow like earth, dry, and devoid of spirit.
Shao's Commentary: Spleen is Yin Earth; yellow is the true color of Earth. Spleen Yang deficiency fails to move Yang, resulting in absent Cun Kou pulse. Weak Yang nearing exhaustion causes cold air and lack of warmth. All symptoms reflect pure Yin-turbidity acting, with faint Yang about to be buried. Spleen True Qi is exhausted, and the Earth's true color reveals itself externally, causing total body yellowing. This is a Zang exhaustion syndrome, distinct from jaundice caused by external pathogens.
Yizong Jinjian states: Blackening around the mouth with cold sweat is a fatal Yin Jaundice sign. Dry, withered body resembling smoke is a fatal Yang Jaundice sign.
Shao's Commentary: Yin Jaundice with Yang exhaustion leads to death; Yang Jaundice with Yin depletion also leads to death.
