冯鲁瞻曰∶夫鼻为肺窍。经曰∶天气通于肺。若肠胃无痰火积热，则平常上升，
皆清气也。肺家有病，则鼻不利，如伤热之不散，或伤寒之久郁成热，皆能使塞而
不利。若平人而多涕，或黄或白，或带血如脓状者，皆肾虚所致，不可过用凉药。（《锦囊》）
又曰∶鼻渊者，谓其涕下不止，如淌水泉，故名之也。经曰∶是胆移热于脑。盖
胆脉起于目锐 ，上抵头角，入络于脑。然阳明之脉亦挟鼻，络目旁，约太阳之脉者
也。今因脑热，则足太阳逆，与阳明之脉俱盛，泊于额中，是以鼻额酸痛，涕下不止矣。
又曰∶更有寒邪未尽，虚热渐炽，是以脓涕结聚，香臭不闻，此名鼻 。
又曰∶更有热血入面，为寒所拂，是以污浊凝滞，则成鼻 。
又曰∶脑病有二∶若清水流出而不痛
者，为寒；若流黄臭水而痛者，为热。久而不愈，即名脑漏。治当内服清利胆热，外
于囟会、通天二穴灸之。
又曰∶鼻流浊涕不止者，名曰鼻渊。乃风热烁脑而液下渗，或黄或白，或带血如
脓状，此肾虚之证也。经曰∶脑渗为涕。又曰∶胆移热于脑。《原病式》曰∶如以火烁
金，热极则反化为水。然究其原，必肾阴虚而不能纳气归元，故火无所畏，上迫肺
金，由是津液之气不得降下，并于空窍，转浊为涕，津液为之逆流矣。于是肾肝愈虚，
有升无降，有阳无阴，阴虚则病，阴绝则死。此最宜戒怒以养阳，绝欲以养阴，断
炙，远酒面，以防作热。然后假之良医，滋肾清肺为君，开郁顺气为臣，补阴养血
为佐，俾火息金清，降令胥行，气畅郁分，清窍无壅，阳开阴阖，相根据相附，脏腑各
司乃职，自慎以培其根，药饵以治其病，间有可愈者。苟或骄恣不慎，或误投凉药，虽
仓扁不能使其长生矣。
又曰∶久患鼻流浓涕极臭者，即名脑漏。气虚者，补中益气汤；阴虚者，麦味地黄汤。
经曰∶肺和则能知香臭矣。肺中壅遏不和，故鼻窍窒塞不闻香臭矣。
陈实功曰∶鼻渊又名脑漏，总由风寒凝入脑户，与太阳湿热交蒸而成。其患鼻
流浊涕，或流黄水，点点滴滴，长湿无干，久则头眩虚晕不已，治以藿香汤主之。如
日久虚眩，内服补中益气汤、六味地黄丸，以滋化源可也。（《正宗》）
陈远公曰∶人有无端鼻流清水，日久则流鼻涕，又久则流黄浊之物，如脓如髓，
腥臭难闻，流至十年而死矣。此得之饮酒太过，临风而卧，风入胆中，胆之酒毒，不
能外泄，遂移热于脑，脑得热毒之气，不能久藏，从鼻窍出矣。脑窍通于鼻，而胆
气何以通于脑，酒气何以入于胆耶？凡善饮者，饮酒必先入胆，胆不能受酒，而能
渗酒，酒经胆渗则气尽解，倘饮多则胆不
及渗矣。胆不及渗，则不胜酒，既不及化酒，则火毒存于中，人卧则胆气不行，又
加寒风之吹，胆更不舒矣。胆木最恶者，寒风也，内寒相侵则内热益甚，胆属阳，头
亦属阳，胆热不能久藏胆中，必移热上走于头矣。脑在头中，头无藏热之处，必遇
穴即入，况胆脑原相通者乎。脑之穴大过于胆，遂安居而不还于胆矣。及居脑，久
动则思迁，又寻窍而出，乃顺趋于鼻矣。火毒浅则涕清，深则涕浊，愈久愈流愈重，后
则涕无可流，并脑髓尽出，欲不死不可得矣。治法∶治其脑而仍治其胆者，探源之
治也。用取渊汤∶辛夷二钱，当归、黑山栀各三钱，柴胡、贝母各一钱，元参一两，
水煎服。二剂涕减，三剂全愈。（辛夷入胆，引当归以补脑之气，引元参以解脑之火，加柴、栀舒胆之
郁，则胆不来助火，自受补气之益也。不止鼻之涕者，清脑中之火，益脑中之气，正所以止之也。盖鼻原无涕，遏
上游出涕之源，何必又截下流之水乎！或疑当归过于多用，不知脑髓尽出，若不大补，则脑气不生。辛夷耗散
之物，非可常用，故乘其引导，大用当归补脑渗精，不必日后再用。倘日后减去辛夷，即重用当归无益矣。此
用药先后之机也。人疑当归不可多用，不过嫌其性滑，有妨于脾耳。谁知脑髓直流之人，必髓不能化精者也。精
不化则必少矣，精少则不能分布于大肠，大肠必有干燥之苦，然则以当归润之，正其所喜，何患之有耶！）
又曰∶人有鼻流清涕，经年不愈，人以为内热成脑漏也，谁知肺气虚寒乎？夫
脑漏，即鼻渊也。有寒热二证，不独胆热而成之也。何以别之？盖鼻涕浊而臭者，热
也；清而不臭者，寒也。热属实，寒属虚，今流清涕而不臭，正虚寒也。热宜清凉之
药，寒宜温和之剂，若概用散而不用补，则损肺气而肺益寒，愈流清涕矣。用温肺止
流丹∶人参、荆芥、细辛各五分，诃子、甘草各一钱，桔梗三钱，水煎，调石首鱼脑
骨五钱， 末服，一剂即止。（此方气味温和，自能暖肺，性又带散祛邪，故奏功如神。或谓石首鱼脑骨
古人以治内热之鼻渊，疑石首鱼脑骨为物，何以用治寒证鼻渊耶？恐鼻渊皆属热，而非寒乎？不知鼻渊有寒热
二证，而石首鱼脑骨皆兼治之。但热病之涕通于脑，寒证之涕出于肺，所用之药皆入肺，无非温和之味，肺既
寒凉，得温和自解，又得石首鱼脑骨，截脑中之路，则脑气不下陷，肺气更闭矣，所以一剂止流也。）
又曰∶人有鼻塞不通，浊涕稠粘已经数年，人以为鼻渊，火结于脑也，谁知乃
肺之郁火不宣，而非鼻渊也。夫郁证五脏皆有，不独肺能郁也。《内经》曰∶诸气愤
郁，皆属于肺。肺郁则气不通也。《难经》曰∶肺热甚则出涕。肺本清虚之府，最恶
热也。肺热则气必粗，液必上拂，而结为涕，热甚则涕黄，热极则涕浊，则浊之物，
岂容于清虚之府，必从鼻之门户出矣。用加味逍遥散∶柴胡、白术、白茯苓各二钱，
桔梗、白芍、当归各三钱，黄芩、半夏、白芷、甘草各一钱，陈皮五分，水煎服。二
剂轻，八剂全愈。（此治肝郁之方，何以治肺郁亦效？不知此方善治五郁，非独治肝一经已也。又佐以桔梗散
肺之邪，黄芩泻肺之热，且引众味入肺，何郁之不宣乎？故塞通浊化也。）
李东垣曰∶鼻塞不闻香臭者，俗谓肺寒，而用解利辛温之药不效，殊不知多因
肺经素有火邪，故遇寒便塞也。治当清肺降火为主，佐以通气之剂。如原无鼻塞旧
症，但一时偶感风寒，而致窒塞声重，或流清涕者，自作风寒治之。然气虚之人，气
弱不能上升，则鼻塞滞，所谓九窍不通，肠胃之所生也，多服补中益气汤自通。
朱丹溪曰∶肺开窍于鼻，阳明胃脉亦挟鼻上行，脑为元神之府，鼻为命门之窍，
人之中气不足，清阳不升，则头为之倾，九窍为之不利。经曰∶天气通于肺。若肠胃
无痰火积热，则平常之升，皆清气也。故十二经脉，三百六十五络，其气血皆上升
于面而走空窍，其宗气出于鼻而为臭。谓阳气、宗气者，皆胃中生发之气也。若因
饥饱劳役损伤脾胃，则生发之气弱，而营运之气不能上升，乃邪塞空窍，故鼻不利，
而不闻香臭也。治法宜养胃实营气，阳气、宗气上升则通矣。然《难经》云∶心主五
臭，肺主诸气。鼻者，肺窍也，反闻香臭者，何也？盖以窍言之，肺也；以用言之，
心也。若因卫气失守，寒邪客于头，而鼻
亦受之，不能为用，是以不闻香臭矣。经曰∶五气入鼻，藏于心肺，心肺有病，鼻
为之不利也。视听明而清凉，香臭辨而温暖，治法宜先散寒邪，后补胃气，使心肺
之气得以交通，则鼻利而香臭闻矣。

冯鲁瞻说：鼻子是肺的窍道。医经说：天气通于肺。如果肠胃没有痰火积热，那么平常上升的都是清气。肺家有病，则鼻子不通利，比如感受热邪而不得消散，或者伤寒日久郁结化热，都能导致鼻塞不通利。如果是普通人却多涕，颜色或黄或白，或者带血像脓状，这都是肾虚所致，不可过度使用凉药。（《锦囊》）
又说：鼻渊，是指鼻涕流个不停，像泉水流淌一样，所以叫这个名字。医经说：这是胆移热于脑。因为胆脉起于目外角，向上抵达头角，进入络属于脑。然而阳明脉也挟持鼻子，络属眼旁，约束太阳脉。现在因为脑热，导致足太阳脉逆行，与阳明脉一起亢盛，停滞在额中，所以鼻部和额头酸痛，鼻涕流个不停。
又说：更有寒邪未尽，虚热逐渐炽盛，所以脓涕结聚，闻不到香味和臭味，这叫做鼻鼽（注：原文此处可能有误，通常指鼻窒或鼻渊变证，依文意理解为鼻塞嗅觉失灵）。
又说：更有热血进入面部，被寒邪拂逆，所以污浊凝滞，形成鼻鼽。
又说：脑病有两种：如果流出清水且不痛，属于寒；如果流出黄色臭水且痛，属于热。久治不愈，就叫做脑漏。治疗应当内服清利胆热的药物，外部在囟会、通天两个穴位进行艾灸。
又说：鼻子流浊涕不止的，叫做鼻渊。这是风热灼烧脑部导致津液下渗，或者黄色白色，或者带血像脓状，这是肾虚的证候。医经说：脑渗为涕。又说：胆移热于脑。《原病式》说：就像用火烤金，热极则反化为水。然而追究根源，必然是肾阴虚而不能纳气归元，所以火无所畏惧，向上逼迫肺金，因此津液之气不能下降，并聚于空窍，转浊为涕，津液为之逆流了。于是肾肝更加虚弱，只有升没有降，只有阳没有阴，阴虚则生病，阴绝则死亡。这最宜戒怒以养阳，断绝欲望以养阴，停止吃烧烤食物，远离酒面，以防产生热邪。然后借助良医，以滋肾清肺为主，开郁顺气为辅，补阴养血为佐，使火息金清，降令通行，气畅郁分，清窍无壅塞，阳开阴阖，相互依附，脏腑各司其职，自己谨慎以培固根本，药物来治疗疾病，偶尔有能治愈的。如果骄傲放纵不慎，或者误投凉药，即使是仓公、扁鹊也不能让他长生。
又说：长期患鼻流浓涕极臭的，就叫做脑漏。气虚者，用补中益气汤；阴虚者，用麦味地黄汤。医经说：肺和则能知香臭。肺中壅遏不和，所以鼻窍窒塞闻不到香臭。
陈实功说：鼻渊又名脑漏，总由风寒凝入脑户，与太阳湿热交蒸而成。其症状是鼻流浊涕，或者流黄水，点点滴滴，长久湿润不干，久了则头晕虚晕不已，治疗以藿香汤为主。如果日久出现虚眩，内服补中益气汤、六味地黄丸，以滋养化源即可。（《正宗》）
陈远公说：人有无缘无故鼻流清水，日子久了则流鼻涕，又久了则流黄浊之物，像脓像髓，腥臭难闻，流到十年就会死。这是因为饮酒太过，临风而卧，风进入胆中，胆中的酒毒不能外泄，于是移热于脑，脑得到热毒之气，不能久藏，从鼻窍出去了。脑窍通于鼻，而胆气何以通于脑，酒气何以入于胆呢？凡是善于饮酒的人，饮酒必先入胆，胆不能承受酒，但能渗透酒，酒经过胆渗透则气尽解，如果喝多了则胆来不及渗透。胆来不及渗透，就不能胜酒，既然来不及化酒，则火毒存于其中，人躺下时胆气不行，又加上寒风吹拂，胆更不舒服了。胆木最厌恶的是寒风，内寒相侵则内热更甚，胆属阳，头也属阳，胆热不能久藏胆中，必移热上行到头。脑在头中，头没有藏热之处，必定遇到穴道就进入，何况胆脑原本相通呢。脑的穴道大于胆，于是安居而不返回胆中。等到居住在脑中，久了想移动，又寻找窍道而出，于是顺势趋向于鼻。火毒浅则涕清，深则涕浊，越久流得越重，后来涕无可流，连脑髓都尽出，想要不死都不可能了。治疗方法：治其脑而仍治其胆，是探源的治疗。用取渊汤：辛夷二钱，当归、黑山栀各三钱，柴胡、贝母各一钱，元参一两，水煎服。两剂后鼻涕减少，三剂全愈。（辛夷入胆，引当归以补脑之气，引元参以解脑之火，加柴胡、山栀舒胆之郁，则胆不来助火，自然受补气之益。不止鼻之涕，是因为清脑中之火，益脑中之气，这正是止涕的方法。盖鼻子原本无涕，遏制上游出涕之源，何必又截断下游之水呢！有人怀疑当归过于多用，不知道脑髓尽出，若不大补，则脑气不生。辛夷是耗散之物，不可常用，所以乘其引导，大用当归补脑渗精，不必日后再用。倘若日后减去辛夷，即重用当归也无益了。这是用药先后的关键。人怀疑当归不可多用，不过是嫌其性滑，有妨于脾罢了。谁知道脑髓直流的人，一定是髓不能化精的人。精不化则必少，精少则不能分布于大肠，大肠必有干燥之苦，然而用当归润之，正是其所喜，有什么可担心的呢！）
又说：人有鼻流清涕，经年不愈，人们以为是内热成脑漏，谁知道是肺气虚寒呢？夫脑漏，即鼻渊。有寒热两种证候，不只是胆热而成。如何辨别？鼻涕浊而臭的，是热；清而不臭的，是寒。热属实，寒属虚，现在流清涕而不臭，正是虚寒。热宜清凉药，寒宜温和剂，如果一概用散法而不用补法，则损肺气而肺更寒，流清涕更多。用温肺止流丹：人参、荆芥、细辛各五分，诃子、甘草各一钱，桔梗三钱，水煎，调石首鱼脑骨五钱末服，一剂即止。（此方气味温和，自能暖肺，性又带散祛邪，故奏效如神。有人说石首鱼脑骨古人用来治内热之鼻渊，怀疑石首鱼脑骨这种物，何以用治寒证鼻渊？恐怕认为鼻渊皆属热，而非寒吧？不知道鼻渊有寒热二证，而石首鱼脑骨皆兼治之。但热病的涕通于脑，寒证的涕出于肺，所用之药皆入肺，无非温和之味，肺既寒凉，得温和自解，又得石首鱼脑骨，截断脑中之路，则脑气不下陷，肺气更闭，所以一剂止流。）
又说：人有鼻塞不通，浊涕稠粘已经数年，人们以为是鼻渊，火结于脑，谁知道乃是肺之郁火不宣，而不是鼻渊。夫郁证五脏皆有，不只是肺能郁。《内经》说：诸气愤郁，皆属于肺。肺郁则气不通。《难经》说：肺热甚则出涕。肺本是清虚之府，最恶热。肺热则气必粗，液必上拂，而结为涕，热甚则涕黄，热极则涕浊，这浊之物，岂容于清虚之府，必从鼻之门户出。用加味逍遥散：柴胡、白术、白茯苓各二钱，桔梗、白芍、当归各三钱，黄芩、半夏、白芷、甘草各一钱，陈皮五分，水煎服。两剂减轻，八剂全愈。（这是治肝郁的方子，何以治肺郁也有效？不知道此方善治五郁，不只是治肝一经而已。又佐以桔梗散肺之邪，黄芩泻肺之热，且引众味入肺，何郁之不宣乎？所以塞通浊化。）
李东垣说：鼻塞不闻香臭，俗谓肺寒，而用解利辛温之药不效，殊不知多因肺经素有火邪，故遇寒便塞。治疗当以清肺降火为主，佐以通气之剂。如果原来没有鼻塞旧症，只是一时偶感风寒，而导致窒塞声重，或流清涕的，自然按风寒治疗。然而气虚之人，气弱不能上升，则鼻塞滞，所谓九窍不通，是肠胃之所生，多服补中益气汤自通。
朱丹溪说：肺开窍于鼻，阳明胃脉也挟鼻上行，脑为元神之府，鼻为命门之窍，人的中气不足，清阳不升，则头为之倾，九窍为之不利。医经说：天气通于肺。如果肠胃没有痰火积热，那么平常的升，都是清气。所以十二经脉，三百六十五络，其气血皆上升于面而走空窍，其宗气出于鼻而为臭。谓阳气、宗气者，都是胃中生发之气。如果因饥饱劳役损伤脾胃，则生发之气弱，而营运之气不能上升，乃邪塞空窍，所以鼻不利，而不闻香臭。治疗方法宜养胃实营气，阳气、宗气上升则通了。然而《难经》说：心主五臭，肺主诸气。鼻者，肺窍也，反闻香臭者，为什么呢？盖以窍言之，是肺；以用言之，是心。如果因卫气失守，寒邪客于头，而鼻亦受之，不能为用，是以不闻香臭。医经说：五气入鼻，藏于心肺，心肺有病，鼻为之不利。视听明而清凉，香臭辨而温暖，治疗方法宜先散寒邪，后补胃气，使心肺之气得以交通，则鼻利而香臭闻矣。

Feng Luzhan stated: The nose is the orifice of the Lung. The Classics state: "Heavenly Qi connects with the Lung." If there is no phlegm-fire accumulation-heat in the intestines and stomach, then what normally rises is clear Qi. When the Lung house has disease, the nose becomes obstructed. For example, heat pathogen that does not dissipate, or cold damage that lingers and transforms into heat over time, can both cause obstruction and difficulty in breathing. If a healthy person has excessive nasal discharge, whether yellow or white, or bloody like pus, this is caused by Kidney deficiency. One must not overuse cooling medicines. (*Jinnang*)
He also said: Biyuan (Nasal Sinusitis/Brain Leak) refers to continuous dripping of nasal mucus, like a flowing spring, hence the name. The Classics state: "This is Gallbladder transferring heat to the Brain." The Gallbladder meridian originates at the outer canthus of the eye, ascends to the corner of the head, and enters/connects with the Brain. However, the Yangming meridian also flanks the nose, connects with the side of the eyes, and constrains the Taiyang meridian. Now, due to Brain heat, the Foot-Taiyang meridian rebels, becoming excessive along with the Yangming meridian, stagnating in the forehead. Thus, there is soreness and pain in the nose and forehead, and continuous dripping of nasal mucus.
He also said: Furthermore, if cold pathogen is not fully resolved and deficient heat gradually intensifies, purulent mucus accumulates, and the sense of smell is lost; this is called Biqiu (Nasal Obstruction/Loss of Smell).
He also said: Furthermore, if hot blood enters the face and is rebuffed by cold pathogen, turbid matter stagnates, forming Biqiu.
He also said: There are two types of Brain diseases: If clear water flows out without pain, it is Cold; if yellow, foul-smelling water flows out with pain, it is Heat. If prolonged and unhealed, it is named Naolou (Brain Leakage). Treatment should involve internal administration of herbs to clear and drain Gallbladder heat, and external moxibustion on the Xinhui and Tongtian acupoints.
He also said: Continuous flow of turbid nasal mucus is called Biyuan. This is caused by wind-heat scorching the Brain, causing fluids to seep downward. The discharge may be yellow or white, or bloody like pus; this is a sign of Kidney deficiency. The Classics state: "Brain seepage becomes mucus." It also states: "Gallbladder transfers heat to the Brain." *Yuanbing Shi* says: "Like using fire to smelt metal, extreme heat turns back into water." However, tracing the origin, it is inevitably due to Kidney Yin deficiency failing to grasp Qi and return it to its source. Thus, Fire acts without fear, pressing upward against Lung Metal. Consequently, the Qi of body fluids cannot descend, gathers in the orifices, transforms turbidity into mucus, and causes body fluids to flow in reverse. Thus, Kidney and Liver become increasingly deficient, with only ascending and no descending, only Yang and no Yin. Yin deficiency leads to disease; Yin exhaustion leads to death. One must guard against anger to nourish Yang, abstain from desires to nourish Yin, avoid fried foods, and stay away from alcohol and wheat products to prevent generating heat. Then, relying on a skilled physician, use nourishing Kidney and clearing Lung as the sovereign agents, resolving depression and smoothing Qi as the minister agents, and tonifying Yin and nourishing Blood as the assistant agents. This allows Fire to subside and Metal to clear, descending functions to proceed smoothly, Qi to flow freely and depression to resolve, clear orifices to be unobstructed, Yang opening and Yin closing to support each other, and Zang-Fu organs to perform their duties. By being cautious to cultivate the root and using medicine to treat the illness, occasional cures are possible. But if one is arrogant, indulgent, and careless, or mistakenly uses cooling medicines, even Cang Gong or Bian Que cannot grant longevity.
He also said: Long-term suffering from extremely foul-smelling thick nasal discharge is named Naolou. For Qi deficiency, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction); for Yin deficiency, use Maiwei Dihuang Tang (Lily and Cornus Pill with Rehmannia). The Classics state: "When Lung is harmonious, one can perceive smells." When Lung is congested and disharmonious, the nasal orifice is blocked, and one cannot smell.
Chen Shigong stated: Biyuan is also called Naolou. It is generally caused by cold and congealing into the Brain Gate, interacting with Sun-Yang damp-heat to generate steaming. The symptom is flowing turbid nasal mucus, or yellow water, dripping drop by drop, remaining wet for a long time without drying. Over time, dizziness and voidiness persist. Treatment is primarily Huoxiang Tang (Agastache Decoction). If dizziness persists due to long duration, internally administer Buzhong Yiqi Tang and Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) to nourish the source of transformation. (*Zhengzong*)
Chen Yuangong stated: Some people have spontaneous clear nasal discharge. After a long time, it becomes regular mucus; after even longer, it becomes yellow and turbid matter, like pus or marrow, with an unbearable fishy stench. Flowing for ten years leads to death. This results from excessive drinking and sleeping facing the wind. Wind enters the Gallbladder; the alcohol toxin in the Gallbladder cannot excrete outward, thus transferring heat to the Brain. The Brain receives the heat-toxin Qi and cannot store it long-term, so it exits through the nasal orifice. The Brain orifice connects with the nose, but how does Gallbladder Qi connect to the Brain, and how does alcohol Qi enter the Gallbladder? Those who drink well know that alcohol first enters the Gallbladder. The Gallbladder cannot withstand alcohol but can permeate it. Alcohol permeated by the Gallbladder dissipates its Qi. If one drinks too much, the Gallbladder cannot permeate it in time. Unable to permeate, it cannot overcome the alcohol; unable to transform the alcohol, fire-toxin remains inside. When lying down, Gallbladder Qi does not move, compounded by cold wind blowing, making the Gallbladder uncomfortable. Wood of the Gallbladder hates cold wind most. Internal cold invasion makes internal heat worse. Gallbladder belongs to Yang, and the Head also belongs to Yang. Gallbladder heat cannot stay in the Gallbladder long-term; it must transfer heat upward to the Head. The Brain is in the Head, and the Head has no place to store heat; it enters wherever there is an acupoint. Moreover, Gallbladder and Brain are originally connected. The Brain's acupoints are larger than those of the Gallbladder, so it settles there and does not return. Once settled in the Brain, movement prompts migration, seeking an orifice to exit, trending naturally toward the nose. Shallow fire-toxin yields clear mucus; deep fire-toxin yields turbid mucus. The longer it lasts, the heavier the flow. Eventually, mucus runs out, and brain marrow is entirely expelled; death is inevitable. Treatment method: Treating the Brain while still treating the Gallbladder is treating the source. Use Qiyuan Tang: Xinyi (2 qian), Danggui and Heishanzhi (Black Gardenia) (3 qian each), Chaihu and Beimu (1 qian each), Yuan Shen (1 liang). Decoct in water and take orally. Two doses reduce mucus; three doses cure completely. (Xinyi enters the Gallbladder, guiding Danggui to tonify Brain Qi, and Yuan Shen to resolve Brain Fire. Adding Chaihu and Zhizi soothes Gallbladder depression, so the Gallbladder does not assist Fire and naturally benefits from Qi tonification. Stopping nasal mucus by clearing Brain Fire and benefiting Brain Qi is the correct approach. The nose originally has no mucus; blocking the source upstream is better than damming the stream downstream! Some doubt using large amounts of Danggui, not knowing that when brain marrow is exhausted, large tonification is needed for Brain Qi to regenerate. Xinyi is dispersing and not for long-term use, so during its guiding phase, large doses of Danggui are used to tonify Brain and secrete essence, avoiding later use. If Xinyi is reduced later, heavy Danggui is useless. This is the key to sequential medication. People doubt Danggui due to its slippery nature harming the Spleen. Who knows that those with direct brain marrow leakage definitely fail to transform marrow into essence. Essence fails to transform, so it decreases. Decreased essence cannot distribute to the Large Intestine, causing dryness. Using Danggui to moisten is exactly what is desired; why worry?)
He also said: Some people have clear nasal discharge lasting years. People think it is internal heat causing Naolou, but who knows it is Lung Qi deficiency and Cold? Naolou is Biyuan. There are Cold and Heat syndromes, not just Gallbladder Heat. How to distinguish? Turbid and foul mucus indicates Heat; clear and odorless indicates Cold. Heat is Excess; Cold is Deficiency. Clear, odorless mucus is precisely Deficient-Cold. Heat requires cooling herbs; Cold requires warm-mild agents. If one universally uses dispersing methods without tonification, Lung Qi is damaged and Lung becomes colder, increasing clear discharge. Use Wenfei Zhiliu Dan: Renshen, Jingjie, Xixin (5 fen each), Hezi, Gancao (1 qian each), Jiegeng (3 qian). Decoct in water, mix with 5 qian of Shishouyu Naogu (Turbot Brain Bone) powder, and take orally. One dose stops the flow. (This formula is warm and mild, naturally warming the Lung, and possesses dispersing properties to expel pathogens, achieving miraculous results. Some argue Shishouyu Naogu was used by ancients for internal heat Biyuan, questioning how it treats Cold syndrome Biyuan, suspecting all Biyuan is Heat, not Cold. Not knowing Biyuan has Cold and Heat syndromes, and Shishouyu Naogu treats both. In Heat cases, mucus connects to the Brain; in Cold cases, mucus comes from the Lung. Medications enter the Lung, which are mild-warm. If the Lung is cold-cool, mild-warm resolves it. With Shishouyu Naogu blocking the path from the Brain, Brain Qi does not sink, and Lung Qi closes further, stopping the flow in one dose.)
He also said: Some people have nasal congestion and thick, sticky turbid mucus for years. People think it is Biyuan with Fire knotting in the Brain, but who knows it is Lung Depression-Fire not venting, not Biyuan. Depression syndromes exist in all five Zang organs, not just the Lung. *Neijing* states: "All Qi frustration and depression belong to the Lung." Lung depression means Qi blockage. *Nanjing* states: "Extreme Lung Heat causes mucus discharge." The Lung is a pure-empty organ, hating Heat most. Lung Heat makes Qi coarse and fluids rise, knotting into mucus. Extreme Heat makes mucus yellow; extreme Heat makes mucus turbid. This turbid matter cannot reside in the pure-empty organ and must exit via the nasal gate. Use Jiawei Xiaoyao San: Chaihu, Baizhu, Baifuling (2 qian each), Jiegeng, Baishao, Danggui (3 qian each), Huangqin, Banxia, Baizhi, Gancao (1 qian each), Chenpi (5 fen). Decoct in water and take orally. Two doses bring relief; eight doses cure completely. (This treats Liver Depression; why effective for Lung Depression? Because this formula treats Five Depressions, not just the Liver meridian. Added Jiegeng disperses Lung pathogens, Huangqin drains Lung Heat, and guides other ingredients into the Lung. How can depression not be vented? Thus congestion clears and turbidity dissolves.)
Li Dongyuan stated: Nasal congestion with loss of smell is commonly thought to be Lung Cold, but using pungent-warm resolving medicines is ineffective. Unknowingly, it is often due to pre-existing Fire pathogen in the Lung Meridian, causing blockage upon exposure to cold. Treatment should focus on clearing Lung and descending Fire, assisted by Qi-unblocking agents. If there was no previous history of congestion, but sudden onset due to cold-damp invasion causing stuffiness, heavy voice, or clear discharge, treat as Cold-Damp. However, in Qi-deficient persons, weak Qi cannot ascend, causing nasal stagnation. As stated, "Nine Orifices Blockage" arises from the intestines and stomach; frequent use of Buzhong Yiqi Tang will restore patency.
Zhu Danxi stated: The Lung opens into the nose; the Yangming Stomach Meridian also ascends flanking the nose. The Brain is the mansion of the Original Spirit; the nose is the orifice of the Life Gate. If Middle Qi is insufficient and Clear Yang does not ascend, the head tilts, and the Nine Orifices become unfavorable. The Classics state: "Heavenly Qi connects with the Lung." If there is no phlegm-fire accumulation-heat in the intestines and stomach, normal ascent is Clear Qi. Thus, the Twelve Meridians and 365 Collaterals send Qi and Blood upward to the face and through the orifices. Their Zong Qi (Gathering Qi) emerges from the nose to create smell. Yang Qi and Zong Qi are both generating Qi from the Stomach. If Spleen and Stomach are damaged by hunger, fullness, or labor, generating Qi weakens, and transporting Qi cannot ascend. Pathogens block the orifices, causing nasal disadvantage and inability to smell. Treatment should nourish the Stomach and solidify Ying Qi. When Yang Qi and Zong Qi ascend, patency returns. However, *Nanjing* says: "The Heart governs the Five Odors; the Lung governs all Qi." The nose is the Lung orifice, yet it perceives smells. Why? Speaking of the orifice, it is the Lung; speaking of function, it is the Heart. If Wei Qi (Defensive Qi) fails to guard, and cold pathogen lodges in the head, affecting the nose, it cannot function, leading to loss of smell. The Classics state: "Five Qi enter the nose and store in the Heart and Lung. Disease in Heart and Lung causes nasal disadvantage." Vision and hearing are bright and cool; distinguishing smells is warm. Treatment should first disperse cold pathogen, then tonify Stomach Qi, allowing Heart and Lung Qi to communicate, resulting in nasal patency and perception of smells.
