仲景《金匮》曰∶夫饮有四,何谓也?师曰∶有痰饮,有悬饮,有溢饮,有支饮。其人
素盛今瘦,水在肠间,沥沥有声,谓之痰饮。饮后水流在胁下,咳唾引痛,谓之悬饮。饮水
流行,归于四肢,当汗出而不汗出,身体疼痛,谓之溢饮。咳逆倚息,气短不得卧,其形如
肿,谓之支饮。水在心,心下坚筑,短气,恶水不欲饮。水在肺,吐涎沫,欲饮水。水在脾
,少气身重。水在肝,胁下支满,嚏而痛。水在肾,心下悸。夫心有留饮,其人背恶寒如掌
大。留饮者,胁下痛引缺盆,咳嗽则转甚。胸中有留饮,其人短气而渴,四肢历节痛。脉沉
者,有留饮。膈上病痰,满喘咳吐,发则寒热,背痛腰疼,目泣自出,其人振振身 剧
,必有伏饮。病患饮水多,必暴喘满。凡食少饮多,水停心下,甚者则悸,微者短气。脉双
弦者,寒也。皆大下后善虚,脉偏弦者,饮也。肺饮不弦,但苦喘气短。支饮亦喘而不能卧
,加短气,其脉平也。病痰饮者,当以温药和之。
陈无择曰∶病患百药不效,关上脉伏而大者,痰也。眼皮及眼下如灰烟黑者,痰也。
《活人书》云∶中脘有痰,亦令人憎寒发热,恶风自汗,胸膈痞满,有类伤寒者,但头
不痛、项不强为异。
《原病式》曰∶积饮留饮,积蓄而不散也。水得燥则消散,得湿则不消,以为积饮,土
湿主病故也。大略要分湿热、寒湿之因。
张子和曰∶凡人病痰证有五∶一曰风痰,二曰热痰,三曰湿痰,四曰酒痰,五曰食痰。
如新暴风痰者,形寒饮冷;热痰者,火盛制金;湿痰者,停饮不散;酒痰、食痰者,饮食过
度也。
王节斋曰∶津液者血之余,行乎脉外,流通一身,如天之清露,若血浊气浊,则凝聚而
为痰。痰乃津液之变,如天之露也。故云痰遍身上下,无处不到。盖即津液之在周身者。津
液生于脾胃,水谷所成,浊则为痰,故痰生于脾土也。
薛立斋曰∶凡痰火证,有因脾气不足者,有因脾气郁滞者,有因脾肺之气亏损者,有因
肾阴虚不能摄水。泛而为痰者。有因脾气虚不能摄涎,上溢而似痰者,有因热而生痰者;有
因痰而生热者,有因风寒暑湿而得者,有因惊而得者,有因气而得者,有因酒而得者,有因
食积而得者,有脾虚不能运化而生者,有胸中痰郁而似鬼附者。各审其源而治之。
徐东皋曰∶脾胃为仓廪,所以纳谷,因脾弱不能营运,致血气失于滋养,故不周流,气
道壅滞,中焦不能腐谷,遂停滞而为痰为饮。其变为寒为热,为喘为咳,为呕吐,为反胃,
为肿满,为眩运,为风痫,为嗳气,为吞酸嘈杂,为噎嗝,为怔忡,为疼痛之类,不
可尽状,是皆痰之变病,而其源则出脾湿不流,水谷津液停滞之所致也。
张仲景在《金匮要略》中说:饮邪分为四种,是什么?老师回答说:有痰饮,有悬饮,有溢饮,有支饮。病人平素身体丰盛现在消瘦,水液停留在肠间,发出沥沥的声音,称为痰饮。饮水后水流停滞在胁下,咳嗽吐唾时牵引疼痛,称为悬饮。饮水流行,归于四肢,应当出汗却不出汗,身体疼痛,称为溢饮。咳嗽气逆,倚靠呼吸,气短不能平卧,身形浮肿,称为支饮。水邪在心,心下坚硬悸动,气短,厌恶水不想喝。水邪在肺,吐出涎沫,想喝水。水邪在脾,少气身重。水邪在肝,胁下支撑胀满,打喷嚏时疼痛。水邪在肾,心下悸动。如果心有留饮(停留的水饮),病人背部有一块巴掌大的区域感觉恶寒。留饮病,胁下疼痛牵引至缺盆穴,咳嗽时加重。胸中有留饮,病人气短且口渴,四肢关节遍身疼痛。脉象沉的,是有留饮。膈上有病痰,胸满喘咳吐痰,发作时伴有寒热,背痛腰疼,眼泪自出,病人身体震颤剧烈,必定有伏饮(潜伏的水饮)。病人喝水多,必然突发喘促胀满。凡是吃得少喝得多,水停聚在心下,严重的则心悸,轻微的则气短。脉象双弦的,是寒证。都是大病攻下之后导致虚损,脉象偏弦的,是饮证。肺部的饮邪脉不弦,只是苦于喘促气短。支饮也是喘而不能卧,加上气短,其脉象平和。治疗痰饮病,应当用温药来调和。
陈无择说:病人服用多种药物无效,关上脉象伏而大的,是痰证。眼皮及眼下颜色如灰烟黑者,是痰证。
《活人书》说:中脘有痰,也会让人憎寒发热,恶风自汗,胸膈痞闷胀满,症状类似伤寒,但头不痛、项不强作为区别。
《原病式》说:积饮和留饮,是积蓄而不消散。水遇到燥则消散,遇到湿则不消,形成积饮,这是因为土湿主病的缘故。大略上要区分湿热、寒湿的原因。
张子和说:凡人患痰证有五种:一是风痰,二是热痰,三是湿痰,四是酒痰,五是食痰。比如新得的暴风痰,是因为形寒饮冷;热痰,是因为火盛克制肺金;湿痰,是因为停饮不散;酒痰、食痰,是因为饮食过度。
王节斋说:津液是血的余绪,运行在脉外,流通全身,像天上的清露,如果血浊气浊,则凝聚而成痰。痰是津液的变产物,像天上的露水一样。所以说痰遍布身上下,无处不到。其实就是津液在周身的一部分。津液生于脾胃,由水谷所成,浑浊则为痰,所以痰生于脾土。
薛立斋说:凡是痰火证,有因脾气不足的,有因脾气郁滞的,有因脾肺之气亏损的,有因肾阴虚不能摄水,泛滥而为痰的。有因脾气虚不能摄涎,上溢而似痰的,有因热而生痰的;有因痰而生热的,有因风寒暑湿而得的,有因惊而得的,有因气而得的,有因酒而得的,有因食积而得的,有脾虚不能运化而生的,有胸中痰郁而似鬼附着的。各自审察其源头而治疗。
徐东皋说:脾胃是仓库廪库,用来容纳谷物,因为脾弱不能营运,导致血气失去滋养,所以不能周流,气道壅滞,中焦不能腐熟谷物,于是停滞成为痰为饮。其变化为寒为热,为喘为咳,为呕吐,为反胃,为肿满,为眩晕,为风痫,为嗳气,为吞酸嘈杂,为噎嗝,为怔忡,为疼痛之类,不可尽述,这些都是痰的变病,而其源头则出自脾湿不流,水谷津液停滞所致。
Zhang Zhongjing stated in the *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet): "There are four types of Yin pathogen, what are they?" The master replied: "There is Tan Yin (Phlegm-Fluid), Xuan Yin (Hanging Fluid), Yi Yin (Overflowing Fluid), and Zhi Yin (Branch Fluid). When a patient who was previously robust becomes emaciated, with water accumulating in the intestines making a gurgling sound, it is called Tan Yin. When fluid accumulates under the hypochondrium after drinking, causing pain upon coughing or spitting, it is called Xuan Yin. When water flows into the limbs, sweating should occur but does not, accompanied by body pain, it is called Yi Yin. When there is coughing and wheezing requiring leaning for support, shortness of breath preventing lying flat, and swelling appearance, it is called Zhi Yin. Water in the Heart causes hardness and palpitations below the heart, shortness of breath, aversion to water, and lack of desire to drink. Water in the Lungs causes expectoration of saliva and foam, and desire to drink. Water in the Spleen causes Qi deficiency and heavy body. Water in the Liver causes distension and fullness under the hypochondrium, with pain upon sneezing. Water in the Kidneys causes palpitations below the heart. If there is Liu Yin (Retained Fluid) in the Heart, the patient experiences coldness on the back over an area the size of a palm. In Liu Yin disease, pain under the hypochondrium radiates to the Quepen (LI 12) acupoint, worsening with coughing. If there is retained fluid in the chest, the patient suffers from shortness of breath and thirst, and pain in all joints of the four limbs. A deep pulse indicates retained fluid. Phlegm disease above the diaphragm presents with fullness, wheezing, coughing, and expectoration; upon onset, there are alternating chills and fever, back and waist pain, spontaneous tearing, and severe trembling of the body, indicating Fu Yin (Hidden Fluid). Patients who drink excessive water will suffer from sudden wheezing and fullness. Generally, eating little and drinking much leads to water stagnation below the heart; severe cases cause palpitations, mild cases cause shortness of breath. A double-wiry pulse indicates Cold. These often follow excessive purgation leading to deficiency; a single wiry pulse indicates Fluid retention. Lung fluid retention does not present with a wiry pulse, but rather distress from wheezing and shortness of breath. Zhi Yin also involves wheezing and inability to lie down, plus shortness of breath, with a normal pulse. For treating Tan Yin disease, warm herbs should be used to harmonize."
Chen Wuyue said: "When patients do not respond to various medicines, a伏 (deep/hidden) and large pulse at the Guan position indicates Phlegm. Ash-gray or black discoloration under the eyelids indicates Phlegm."
The *Heren Shu* (Book of Living People) states: "Phlegm in the Zhongwan (CV 12) acupoint can cause aversion to cold and fever, aversion to wind, and spontaneous sweating, with chest and diaphragm stuffiness and fullness, resembling Shanghan (Cold Damage) syndrome, but distinguished by the absence of headache and neck stiffness."
The *Yuan Bing Shi* (Treatise on Original Causes of Disease) says: "Accumulated and retained fluids are those that accumulate without dissipating. Water dissipates when dry but fails to digest when damp, forming accumulated fluid, due to the pathology of Earth-dampness. Broadly, one must distinguish between Damp-Heat and Cold-Damp causes."
Zhang Zihe said: "There are five types of Phlegm diseases in humans: first, Feng Tan (Wind-Phlegm); second, Re Tan (Heat-Phlegm); third, Shi Tan (Damp-Phlegm); fourth, Jiu Tan (Wine-Phlegm); fifth, Shi Tan (Food-Phlegm). For example, acute Wind-Phlegm arises from exposure to cold and consumption of cold drinks; Heat-Phlegm arises from excessive Fire suppressing Metal (Lung); Damp-Phlegm arises from stagnant fluids failing to dissipate; Wine-Phlegm and Food-Phlegm arise from dietary excess."
Wang Jiezhai said: "Jin Ye (Body Fluids) are the surplus of Blood, circulating outside the vessels throughout the body, like clear dew from heaven. If Blood and Qi become turbid, they condense into Tan (Phlegm). Tan is a transformation of Jin Ye, like dew. Thus, it is said that Tan pervades the entire body, reaching everywhere. It is essentially the Jin Ye circulating in the body. Jin Ye is generated by the Spleen and Stomach from food and water; when turbid, it becomes Tan. Therefore, Tan originates from Spleen-Earth."
Xue Lizhai said: "Regarding Tan Huo (Phlegm-Fire) syndromes, some arise from Spleen Qi deficiency, some from Spleen Qi stagnation, some from depletion of Spleen and Lung Qi, and some from Kidney Yin deficiency failing to control water, leading to flooding and formation of Phlegm. Some arise from Spleen Qi deficiency failing to contain saliva, which overflows upwards resembling Phlegm. Some arise from Heat generating Phlegm; some from Phlegm generating Heat. Others result from Wind-Cold, Summer-Heat, or Dampness; from Fright; from Qi stagnation; from Wine; from Food stagnation; from Spleen deficiency failing to transform and transport; or from Phlegm stagnation in the chest resembling spirit possession. Each must be treated according to its root source."
Xu Donggao said: "The Spleen and Stomach are the granaries responsible for receiving grain. Due to Spleen weakness failing to circulate and transport, Blood and Qi lose nourishment and fail to flow freely. Qi pathways become obstructed, and the Middle Jiao fails to rot and ripen grain, leading to stagnation as Phlegm and Fluid. Its transformations include Cold or Heat, Wheezing or Cough, Vomiting or Reverse Regurgitation, Swelling and Fullness, Vertigo, Wind-Seizures, Belching, Acid Regurgitation and Dyspepsia, Dysphagia, Palpitations, Pain, and other conditions too numerous to describe. All these are variations of Phlegm diseases, originating from Spleen-Dampness failing to flow and the stagnation of Grain-Jin Ye."
