黄汗，汗出染衣，黄如柏汁是也。
〔仲〕问曰∶黄汗之为病，身体肿，发热，汗出而渴，状如风水，汗沾衣，色正黄如柏汁，
脉沉，何从得之？师曰∶以汗出时入水中浴，水从汗孔入得之，宜 芍桂酒汤主之。
黄 白芍药（各五两） 桂枝（三两）
上三味，以苦酒一升，水七升相和，煮取三升，温服一升。初发当心烦、服至六七日乃解。若
心烦不止者，以苦酒阻故也。（一方用好酒代苦酒。）
黄汗之病，两胫自冷，假令发热，此属历节。食已汗出，又身常暮盗汗出者，此劳气也。若汗
出已反热者，久久其身必甲错。若发热不止者，必生恶疮。若身重，汗出已辄轻者，久久身必 。
又胸前痛，腰上有汗，腰下无汗，腰 弛痛，如有物在皮中状，剧者不能食，身疼重，烦躁，
小便不利者，此为黄汗，桂枝加黄 汤主之。（方见本门表疸下。）
脉浮而洪，浮则为风，洪则为气。风气相搏，风强则为隐疹，身体为痒，痒为泄风，久为痂
癞；气强则为水，难以俯仰。风气相击，身体洪肿，汗出乃愈。恶风则虚，此为风水；不恶风者，
小便通利，上焦有寒，其口多涎，此为黄汗。
经云∶目黄者，曰黄胆。然亦有目黄而身不黄者，故宜另立篇门。
风气自阳明入胃，循脉而上至目 ，其人肥，风气不得外泄，则为热中而目黄。（全文见诸风条。）
〔河〕青龙散治风气传化，腹内疼结而目黄，风气不得泄，为热中烦渴引饮。
地黄 威灵仙 防风 荆芥穗 何首乌（去黑皮，米泔浸一宿，竹刀切。各二两）
上为末。每日三服，食后沸汤调下一钱。
〔《类》〕治黄胆，目黄不除。用瓜丁为细末，如豆大，纳鼻中，令病患深吸，取鼻中黄
水出，愈。
针灸 目黄有五法∶
其一取心。经云∶心少阴之脉，所生病者，目黄胁痛云云。
其二取心主。经云∶心主手厥阴之脉，是动则病面赤目黄云云
其三取小肠。经云∶小肠手太阳之脉，所生病者，耳聋面黄云云。
其四取大肠。经云∶大肠手阳明之脉，所生病者，目黄口苦云云。
其五取膀胱。经云∶膀胱足太阳之脉，所生病者，目黄泪出云云。
以上五法，并视盛虚寒热陷下取之。
Yellow sweat refers to a condition where sweat stains the clothing yellow, resembling the juice of Phellodendri Cortex (Huangbai).
[Zhang Zhongjing] asked: Regarding Yellow Sweat disease, characterized by bodily swelling, fever, sweating with thirst, symptoms resembling Fengshui (Wind-water edema), sweat staining clothes yellow like Phellodendri Cortex juice, and a deep pulse, how is it contracted? The Master said: It is contracted when one bathes in water while sweating; water enters through the sweat pores. It should be treated primarily with Shaoyao Guizhi Jiu Tang (Peony and Cinnamon Twig Wine Decoction).
Formula for Yellow Sweat: Baishao Yao (Radix Paeoniae Alba) [5 liang each], Guizhi (Ramulus Cinnamomi) [3 liang].
The above three ingredients are mixed with one sheng of Kujiu (bitter wine/vinegar) and seven sheng of water, boiled down to three sheng. Take one sheng warm. Initially, there may be mental restlessness; after six or seven days, the condition resolves. If mental restlessness persists, it is due to the obstruction caused by Kujiu. (Another prescription uses good wine instead of Kujiu.)
In Yellow Sweat disease, the calves are naturally cold; if they feel hot, this belongs to Lijie (Migratory Arthritis). Sweating after eating, along with frequent night sweats in the evening, indicates Laoqi (Consumptive Qi deficiency). If fever persists after sweating, the skin will eventually become rough and scaly (Jiacuo). If fever continues indefinitely, malignant sores will likely develop. If the body feels heavy but becomes lighter after sweating, over time the body will become emaciated or flaccid. Additionally, chest pain, sweating above the waist but not below, lax pain in the lower back, a sensation as if something is trapped in the skin, inability to eat in severe cases, body ache and heaviness, irritability, and difficult urination indicate Yellow Sweat, which should be treated with Guizhi Jia Huangqi Tang (Cinnamon Twig Decoction plus Astragali Radix). (See formula under Jaundice-Exterior section.)
A floating and surging pulse: floating indicates Wind, surging indicates Qi (Heat). When Wind and Heat struggle, strong Wind manifests as Yin Zhen (urticaria) with itching; chronic itching leads to Ji Lai (scabies/lichenification). Strong Heat leads to edema, making flexion and extension difficult. When Wind and Heat strike each other causing severe edema, sweating leads to recovery. Aversion to wind indicates deficiency, known as Fengshui; no aversion to wind, with free urination, cold in the Upper Jiao, and excessive salivation, indicates Yellow Sweat.
The Classic states: Those with yellow eyes are called Huangdan (Jaundice). However, some have yellow eyes without yellowing of the body, so a separate chapter is established.
Wind-Qi enters the Stomach via the Yangming channel, ascending to the inner canthus. In obese individuals, Wind-Qi cannot dissipate externally, leading to Rezhong (Internal Heat) and yellow eyes. (Full text see General Wind section.)
[Li Dongyuan] Qinglong San (Azure Dragon Powder) treats Wind-Qi transformation causing abdominal pain and nodules with yellow eyes, where Wind-Qi fails to vent, resulting in Internal Heat, irritability, and thirst.
Dihuang (Radix Rehmanniae), Weilingxian (Herba Clematidis), Fangfeng (Radix Saposhnikoviae), Jingjie Sui (Flos Schizonepetae), Heshouwu (Radix Polygoni Multiflori Preparata) [2 liang each, processed as described].
Grind into powder. Take one qian mixed with boiling water after meals, three times daily.
[Classics] Treats Jaundice where yellow eyes persist. Use Guding (Gua蒂 powder) finely ground. Place a bean-sized amount in the nose, instruct the patient to inhale deeply to discharge yellow fluid from the nose, curing the condition.
Acupuncture treatment for yellow eyes has five methods:
First, select Heart meridian points. The Classic states: The Hand-Shaoyin Heart Meridian diseases include yellow eyes and flank pain.
Second, select Pericardium meridian points. The Classic states: The Hand-Jueyin Pericardium Meridian disturbances cause red face and yellow eyes.
Third, select Small Intestine meridian points. The Classic states: The Hand-Taiyang Small Intestine Meridian diseases include deafness and yellow complexion.
Fourth, select Large Intestine meridian points. The Classic states: The Hand-Yangming Large Intestine Meridian diseases include yellow eyes and bitter taste.
Fifth, select Bladder meridian points. The Classic states: The Foot-Taiyang Bladder Meridian diseases include yellow eyes and tearing.
For all five methods, select points based on excess/deficiency, cold/heat, and sinking conditions.
