黄帝向岐伯问道:饮食水谷进入口中,输送到肠胃。其中的液体分为五种情况。天气寒冷、衣服单薄时,就变成尿液和气体;天气炎热、衣服厚实时,就变成汗液。悲哀情绪导致气机郁结,就变成眼泪;体内有热且胃壁松弛时,就变成唾液。邪气在体内逆乱,就会导致气机闭塞不通。气机不通畅就会形成水胀病。我知道这些现象是这样的,但不知道它们是如何产生的,希望听听其中的道理。
岐伯回答说:饮食水谷都进入口中,味道分为五味,各自注入相应的“海”(指气血汇聚之处)。津和液各自运行其特定的通道。所以三焦发出气,用来温煦肌肉,充实皮肤,这叫做“津”;流动缓慢而不外泄的,叫做“液”。天气暑热、衣服厚实时,腠理(皮肤纹理及汗孔)张开,所以出汗。寒气停留在分肉(肌肉间隙)之间,凝聚成沫,就会引起疼痛。天气寒冷时,腠理闭合,湿气之气不能向外发散,水液向下流入膀胱,就变成尿液和气体。五脏六腑中,心是主宰,耳是听者,目是观察外界的代表,肺是宰相,肝是将帅,脾是卫护者,肾是主管体表的。因此,五脏六腑的津液,都向上渗透于眼睛。人心悲则气机郁结,导致心脉拘急;心脉拘急,则牵引肺脏上举;肺脏上举,则津液上溢。但是心脉与肺脏不能经常处于上举状态,而是忽上忽下,所以出现咳嗽并流出眼泪。体内有热则胃中消化食物过快,消化过快则肠道寄生虫上下活动,导致肠胃充满扩张,所以胃壁松弛;胃壁松弛则气机上逆,所以吐出唾液。五谷产生的津液,调和融合成为膏脂状的物质,向内渗入骨空,补益脑髓,并向下游走至大腿内侧。如果阴阳不和,就会导致津液外溢并向下流注于阴部。髓液都会减少并向下流失,如果流失过度就会造成虚损,虚损所以导致腰背疼痛和小腿酸软无力。如果阴阳气道不通畅,四海(指髓海、血海、气海、水谷之海)闭塞,三焦不能通泻,津液不能正常化生,水谷并行于肠胃之中,在回肠处被区分开,滞留于下焦,不能渗入膀胱,就会导致下焦胀满。水液泛滥就会形成水胀病。这就是津液五种分流中的顺逆规律。
这一段一问一答的结构并不奇特,措辞也没有特别精警的地方。“五癃”指的是气的逆行称为“厥”,津液的逆行称为“癃”。“津液别”是指津与液在质地上有五种不同。
Huangdi asked Qibo: When food and drink enter the mouth, they are transported to the intestines and stomach. The fluids derived from them differentiate into five types. In cold weather with thin clothing, they become urine and gas; in hot weather with thick clothing, they become sweat. Grief causes Qi to congregate, resulting in tears; internal heat with a relaxed stomach wall results in saliva. When pathogenic factors reverse internally, Qi becomes obstructed and fails to circulate. Failure of circulation leads to water distension (Shuizhang). I know these phenomena occur, but I do not understand their origin. I wish to hear the principle behind them.
Qibo replied: Food and drink enter the mouth, and their flavors are divided into five categories, each pouring into its respective "Sea" (where Qi and Blood gather). Jin (thin fluid) and Ye (thick fluid) travel along their specific pathways. Thus, Sanjiao (Triple Burner) emits Qi to warm the muscles and fill the skin; this is called Jin. What flows slowly and does not exit externally is called Ye. In hot weather with thick clothing, the Couli (pores and interstitial spaces) open, so sweat is excreted. Cold lingering between the Fenrou (muscle intervals) condenses into foam, causing pain. In cold weather, the Couli close, dampness-Qi cannot move outward, and water flows downward into the Bladder, becoming urine and gas. Among the Zang and Fu organs, the Heart is the ruler, the Ears are the listeners, the Eyes are the observers, the Lungs are the ministers, the Liver is the general, the Spleen is the defender, and the Kidneys govern the exterior. Therefore, the Jin and Ye of all Zang and Fu organs seep upward into the eyes. When one is sad, Qi congregates, causing the Xinmai (Heart Vessel) to contract tightly. Tight contraction of the Heart Vessel lifts the Lung. When the Lung is lifted, fluids overflow upward. However, the Heart Vessel and Lung cannot remain lifted constantly; they rise and fall intermittently, thus causing coughing and tearing. Internal heat causes rapid digestion of grain in the Stomach. Rapid digestion causes intestinal parasites to move up and down, filling and expanding the intestines and stomach, leading to a relaxed stomach wall. A relaxed stomach wall causes Qi to rebel upward, resulting in spitting saliva. The Jin and Ye from the five grains harmonize and combine to form a paste-like substance. This substance penetrates inward into the bone cavities to nourish the brain marrow and flows downward to the inner thighs. If Yin and Yang are disharmonious, fluids overflow and flow downward into the yin regions. Marrow fluids decrease and flow downward; excessive loss leads to deficiency. Deficiency causes lower back and waist pain and weakness in the shins. If the Qi and blood channels of Yin and Yang are blocked, the Four Seas are obstructed, Sanjiao fails to drain, and Jin and Ye fail to transform. Water and grain travel together within the intestines and stomach, separating at the Hui Chang (Lower Intestine), remaining in the Lower Jiao, and failing to渗 (seep) into the Bladder. This causes distension in the Lower Jiao. Overflowing water leads to water distension. This describes the normal and abnormal differentiation of the five types of Jin and Ye.
The question-and-answer structure here is unremarkable, and the wording lacks particular brilliance. "Wu Long" refers to the reversal of Qi as "Jue" and the reversal of Jin/Ye as "Long". "Jin Ye Bie" indicates that Jin and Ye differ in substance into five types.
