【脉象与证候】 脉象沉,口渴想喝水,小便不通畅,都会导致身体发黄。脉象沉是阳明经蓄积热邪的表现,患者喜欢自然出汗。如果出汗后立即进入水中洗浴,热气郁结在体内导致身体浮肿,发热但不口渴,这种病症称为黄汗。脉象紧而数,是因为饥饿后发热,或因饮食过量损伤了胃气,进食后腹部胀满,这种病症称为谷疸。“数”脉代表热,热盛则食欲旺盛;“紧”脉代表寒,寒盛则腹部胀满。脉象浮而紧,是因为突然受热后洗冷水澡,热气潜伏在胸中,全身和眼睛都像金色一样发黄,这种病症称为黄疸(此处指阳黄重症)。如果是阳明病,脉象迟缓的,吃饭不能吃饱,吃饱了就感到心烦、头晕目眩的,一定伴有小便困难,这是将要发生谷疸的前兆。脉象沉弦或紧细,是因为饮酒导致全身血脉发热,又当风受寒或入水,心中烦闷懊恼,脚心发热,这种病症称为酒疸。如果脉象浮且想呕吐的,先用催吐法治疗;如果脉象沉弦的,先用泻下法治疗。脉象浮而紧,是因为在大热天交接房事后立即入水,肾气虚弱,寒气流入脾脏,额头发黑,下午申时发热,小腹部拘急不适,脚底发热,大便色黑,时而稀溏,这种病症称为女劳疸。如果腹部像有水状(鼓胀),属于难治之症。如果寸口脉搏摸不到,口鼻冰冷,也属于难治之症。这类疾病表现为身体发热,全身疼痛,发黄且小便涩滞。
【病因】 内热加上入水洗浴,湿热在体内郁结,冲犯并激发胃气。虽然黄疸分为五种类型,但本质上都是湿热所致。
【治疗】 所有患黄疸的人,只要通过利小便的方法就能痊愈。假如脉象浮,用发汗法解除表邪;如果大便通畅且自然出汗,可以用泻下法治愈。病程以十八天为期限,治疗十天左右病情好转,如果反而加重则难以治疗。治疗方法主要是疏泄湿气、通利小便、清热或者发汗,可以使用五苓散加入茵陈蒿,类似的方法还有很多。
茵陈栀子汤:茵陈(一两,去掉茎部)、大黄(半两)、山栀(十个),用豆豉汤送服。
五苓散:如果热重加苦参;口渴加瓜蒌根;小便涩滞加葶苈子;素来有热加黄连。
茵陈蒿汤:治疗黄疸,症状为寒热往来、不能进食,进食后头晕目眩,心胸不安定的患者适用。
滑石石膏丸:治疗女劳疸。症状见前述标题下的描述。用法是将滑石、石膏研成末服用,用米粥汁送下,一旦大便通畅即停止服用。
[Pulse and Symptoms] A deep pulse, thirst with desire to drink water, and difficult urination all lead to jaundice. A deep pulse indicates heat accumulation in the Yangming channel, accompanied by spontaneous sweating. If one enters water immediately after sweating, heat becomes constrained within the body causing edema, fever without thirst; this condition is named Huanghan (Yellow Sweat). A tight and rapid pulse indicates fever following starvation or stomach injury due to overeating, leading to abdominal fullness after meals; this is called Gujdan (Grain Jaundice). "Rapid" indicates heat, which increases appetite; "tight" indicates cold, which causes abdominal fullness. A floating and tight pulse results from bathing in cold water while suddenly overheated, where heat lies concealed in the chest, causing the whole body and eyes to turn golden yellow; this is named Huangdan (Jaundice). In Yangming disease, a slow pulse suggests that one cannot eat until full; if fullness leads to irritability and dizziness, accompanied by difficult urination, it indicates impending Gujdan (Grain Jaundice). A deep, wiry, or tight-thin pulse, caused by alcohol consumption generating heat in all vessels followed by exposure to wind or water, resulting in mental restlessness and heat in the soles of the feet, is called Jiudan (Alcohol Jaundice). If the pulse is floating with nausea, induce vomiting first; if deep and wiry, purge first. A floating and tight pulse, occurring after intercourse during extreme heat followed by entering water, where Kidney Qi deficiency allows cold to flow into the Spleen, presenting with black forehead, afternoon fever, lower abdominal urgency, heat in the soles, black stool, and occasional loose stools, is called Nulaodan (Female Labor Jaundice). Abdominal distension resembling ascites is intractable. Absence of pulse at the Cun Kou (Radial artery) and cold nose and mouth are also intractable. The disease presents with body heat, generalized pain, jaundice, and dysuria.
[Etiology] Internal heat combined with water exposure causes damp-heat to stagnate internally, stirring up Stomach Qi. Although there are five types of jaundice, they are all caused by damp-heat.
[Treatment] For all patients with jaundice, recovery is achieved primarily by promoting diuresis. If the pulse is floating, resolve via sweating; if stool is unobstructed and spontaneous sweating occurs, treat via purgation. The expected duration is eighteen days; improvement should occur within ten days. If symptoms worsen, it is difficult to treat. Therapeutic methods include dispersing dampness, promoting diuresis, clearing heat, or inducing sweating. Wuling San (Five-Ling Powder) added with Yinchen Hao (Artemisiae Scopariae Herba) is used, along with similar formulas.
Yinchen Zhizi Tang (Inula and Gardenia Decoction): Yinchen (30g, stems removed), Dahuang (15g), Shanzhi (10 fruits). Take with Douchi Tang (Fermented Soybean Decoction).
Wuling San (Five-Ling Powder): Add Kushen (Sophorae Flavescentis Radix) for severe heat; add Gualougen (Trichosanthis Radix) for thirst; add Tingli (Descurainiae Semen) for dysuria; add Huanglian (Coptidis Rhizoma) for inherent heat.
Yinchen Hao Tang (Artemisia Decoction): Treats jaundice characterized by alternating chills and fever, anorexia, dizziness after eating, and discomfort in the heart and chest.
Huashi Shigao Wan (Talcum and Gypsum Pill): Treats Nulaodan (Female Labor Jaundice). See symptoms described above. Grind Huashi (Talcum) and Shigao (Gypsum Fibrosum) into powder, take with rice broth. Stop when bowel movement becomes smooth.
