人有无端鼻流清水者，久则流涕，又久则流黄浊之物，如脓如髓，腥臭不堪闻
者，流至十年，而人死矣。此病得之饮酒太过，临风而卧，风入胆中，胆之酒毒，
不能外泄，遂移其热于脑中。夫脑之窍通于鼻，而胆之气，何以通于脑，而酒之气
何以入于胆耶？凡善饮酒者，胆气自旺，且多叫号，故酒先入胆，而胆不胜酒，即
不及化酒，而火毒存于其中矣。夫胆属木，最恶者寒风也，外寒相侵，则内热愈甚。
胆属阳，而头亦属阳，胆移热而上走于头，脑在头之中，头无可藏热之处，故遇穴
而即入。况胆与脑原是相通，脑之穴大过于胆，遂乐于相安居之，而不肯还入于胆
矣。迨居脑既久，而动极思迁，又寻窍而出，乃顺趋于鼻矣。火毒浅而涕清，火毒
深而涕浊，愈久愈流而愈重，后则涕无可流，并脑髓而尽出，欲不死而不可得矣。
治法治其脑可也，然治其脑，必仍治其胆者，探源之治也。方用取渊汤∶
辛夷（二钱） 当归（二两） 柴胡（一钱） 炒栀子（三钱） 玄参（一两） 贝母（一钱）
水煎服。一剂涕减，再剂涕又减，三剂病全愈。
盖辛夷最能入胆，引当归以补脑之气，引玄参以解脑之火，加柴胡、栀子以舒
胆中之郁热，则胆不来助火，而自受补气之益也。然不去止鼻中之涕者，清脑中之
火，益脑中之气，正所以止之也。盖鼻中原无涕，遏抑上游出涕之源，何必截下流
之水乎。此治法之神耳。或疑当归过于多用，不知脑髓尽出，不大补则脑之气不生。
辛夷耗散之物，非可常用也，故乘其引导，大用当归以补脑添精，不必日后之再用。
倘后日减去辛夷，即重用当归无益矣。此用药先后之机，又不可不识也。人疑当归
之不可多用者，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，精不能化，则精必少，精少则不能分布于大肠，必有干燥之苦，然则用当归以
润之，正其所喜，何虑之有。
此症用探渊丹亦能奏功。
辛夷（一钱） 当归（五钱） 麦冬（二两） 茯苓（三钱） 黄芩（二钱） 白芍（一两）
天花粉（三钱） 生地（五钱） 桔梗（二钱） 水煎服。
四剂全愈。
人有鼻流清涕，经年不愈，是肺气虚寒，非脑漏也。夫脑漏即鼻渊也，原有寒
热二症，不止胆热而成之也。然同是鼻渊，而寒热何以分乎？盖涕臭者热也，涕清
而不臭者寒也。热属实热，寒属虚寒。兹但流清涕而不腥臭，正虚寒之病也。热症
宜用清凉之药，寒症宜用温和之剂，倘概用散而不用补，则损伤肺气，而肺金益寒，
愈流清涕矣。方用温肺止流丹∶
诃子（一钱） 甘草（一钱） 桔梗（三钱） 石首鱼脑骨（五钱， 过存性为末） 荆芥（五分）
细辛（五分） 人参（五分） 水煎调服。一剂即止流矣，不必再服也。
此方气味温和，自能暖肺，而性又带散，更能祛邪，故奏功如神。或谓石首脑
骨，古人以治内热之鼻渊，是为寒物，何用之以治寒症之鼻渊耶？不知鼻渊实有寒
热二症，而石首脑骨寒热二症皆能治之。但热症之涕通于脑，寒症之涕出于肺，我
用群药皆入肺之药也，无非温和之味，肺既寒凉，得温和而自解，复得石首脑骨佐
之，以截脑中之路，则脑气不下陷，而肺气更闭矣。所以一剂而止流也。
人有鼻塞不通，浊涕稠粘，已经数年，皆以为鼻渊而火结于脑也，谁知是肺经
郁火不宣，有似于鼻渊，而非鼻渊乎。夫郁病五脏皆有，不独肝木一经之能郁也。
《内经》曰∶诸气 郁，皆属于肺。肺气郁则气不通，而鼻乃肺经之门户，故肺气不
通，而鼻之气亦不通也。《难经》曰∶肺热甚则出涕。肺本清虚之府，最恶者热也，
肺热则肺气必粗，而肺中之液，必上沸而结为涕，热甚则涕黄，热极则涕浊，败浊
之物，岂容于清虚之腑，自必从鼻之门户而出矣。方用逍遥散加味治之。
柴胡（二钱） 当归（三钱） 白术（二钱） 陈皮（五分） 甘草（一钱） 黄芩（一钱）
茯苓（二钱） 白芍（三钱） 白芷（一钱） 桔梗（三钱） 半夏（一钱） 水煎服。一剂轻，
二剂又轻，连服八剂全愈。
此方治肝木之郁者也，何以治肺郁而亦效？不知逍遥散善治五郁，非独治肝经
一部之郁已也。况佐之桔梗，散肺之邪，加之黄芩泻肺之热，且引群药直入肺经，
何郁之不宣乎。故壅塞通稠浊化也。
此症用宣肺散亦佳。
柴胡 黄芩 紫菀（各二钱） 白芍（一两） 当归 麦冬（各五钱） 茯苓
白芥子（各三钱） 甘草 款冬花（各一钱） 紫苏（一钱） 辛夷（五分）
水煎服。四剂愈。
有人无缘无故地鼻子流出清水，时间久了变成流鼻涕，更久则流出黄浊的液体，像脓又像骨髓，气味腥臭难闻。如果这种情况持续十年，人就会死亡。这种病是因为饮酒过量，又对着风睡觉，导致风邪侵入胆中，胆中的酒毒无法向外宣泄，于是将热邪转移到脑中。脑的窍穴与鼻相通，那么胆的气机为何能通达于脑，而酒气为何能进入胆呢？凡是善于饮酒的人，胆气自然旺盛，且多大声呼叫，所以酒气先入胆，而胆承受不住酒力，来不及化解酒气，火毒便存留其中。胆属木，最畏惧寒风，外寒侵袭，则内热更加严重。胆属阳，头部也属阳，胆将热邪转移并向上走窜至头部，脑位于头部之中，头部没有容纳热邪的地方，所以热邪遇到穴位就进入。况且胆与脑原本就是相通的，脑的穴位远大于胆，所以热邪乐于在脑中安居而不肯回到胆中。等到在脑中居住久了，动极思迁，又寻找窍穴而出，于是顺势趋向于鼻。火毒浅则鼻涕清稀，火毒深则鼻涕浑浊，时间越久流得越多且病情越重，后来鼻涕流无可流，连同脑髓一起全部排出，想要不死都不可能了。治疗时治脑是可以的，然而治脑必须仍要治胆，这是探求根源的治疗方法。方剂用取渊汤：辛夷（二钱）、当归（二两）、柴胡（一钱）、炒栀子（三钱）、玄参（一两）、贝母（一钱），水煎服。服用一剂鼻涕减少，再服一剂鼻涕又减少，服三剂病全愈。
因为辛夷最能入胆经，引导当归来补益脑气，引导玄参来解除脑火，加入柴胡、栀子来疏通胆中的郁热，这样胆就不来助长火势，而自然受到补气的好处。然而不去直接止住鼻中的鼻涕，而是清除脑中的火，补益脑中的气，这正是止住鼻涕的方法。因为鼻中原无鼻涕，遏制上游出涕的源头，何必去截断下游的水呢。这是治疗方法的神妙之处。有人怀疑当归用量过大，不知道脑髓尽出，不大量进补则脑气无法生成。辛夷是耗散的药物，不可常用，所以趁着它引导的作用，大剂量使用当归来补脑添精，不必日后再用。如果日后减去辛夷，即使重用当归也没有益处。这是用药先后的关键，不可不认识。人们怀疑当归不可多用，不过是嫌弃其性质滑利，妨碍脾胃罢了，谁知道脑髓直流的人，一定是髓不能化精的人，精不能化生，则精必少，精少则不能分布于大肠，必然有干燥的痛苦，那么使用当归来润燥，正是它所喜欢的，有什么可忧虑的呢。
此症用探渊丹也能奏效。
辛夷（一钱）、当归（五钱）、麦冬（二两）、茯苓（三钱）、黄芩（二钱）、白芍（一两）、天花粉（三钱）、生地（五钱）、桔梗（二钱），水煎服。
四剂全愈。
有人鼻子流清涕，经过一年不愈，这是肺气虚寒，不是脑漏。所谓脑漏即鼻渊，本来就有寒热两种症状，不只是由胆热形成的。然而同样是鼻渊，寒热如何区分呢？大概鼻涕腥臭的是热证，鼻涕清稀且不腥臭的是寒证。热证属实热，寒证属虚寒。这里只流清涕且不腥臭，正是虚寒的病。热证宜用清凉的药，寒证宜用温和的剂，如果一概用发散药而不用补益药，则会损伤肺气，使肺金更寒，流清涕更多。方剂用温肺止流丹：诃子（一钱）、甘草（一钱）、桔梗（三钱）、石首鱼脑骨（五钱，煅存性研为末）、荆芥（五分）、细辛（五分）、人参（五分），水煎调服。一剂即停止流涕，不必再服。
此方气味温和，自然能暖肺，而性质又带有发散，更能祛除邪气，所以见效如神。有人说石首鱼脑骨，古人用来治疗内热的鼻渊，它是寒性药物，为何用来治疗寒症的鼻渊呢？不知道鼻渊确实有寒热两种症状，而石首鱼脑骨寒热两种症状都能治疗。但热证的鼻涕通于脑，寒证的鼻涕出于肺，我用群药都是入肺经的药，无非是温和的味道，肺既寒凉，得到温和之气自然缓解，再加上石首鱼脑骨辅助，以截断脑中之路，使脑气不下陷，而肺气更闭固。所以一剂就能止住流涕。
有人鼻塞不通，浊涕稠粘，已经数年，都认为是鼻渊而火结于脑，谁知道这是肺经郁火不宣，看似鼻渊，而非鼻渊。郁病五脏都有，不独肝木一经能郁。《内经》说：各种气郁，都属于肺。肺气郁结则气不通，而鼻是肺经的门户，所以肺气不通，鼻的气也不通。《难经》说：肺热甚则出涕。肺本是清虚之府，最厌恶热邪，肺热则肺气必粗，肺中的津液，必上沸而凝结为涕，热甚则涕黄，热极则涕浊，败浊之物，岂容于清虚之腑，必然从鼻的门户而出。方剂用逍遥散加味治疗。
柴胡（二钱）、当归（三钱）、白术（二钱）、陈皮（五分）、甘草（一钱）、黄芩（一钱）、茯苓（二钱）、白芍（三钱）、白芷（一钱）、桔梗（三钱）、半夏（一钱），水煎服。一剂减轻，二剂又减轻，连服八剂全愈。
此方治疗肝木之郁，为何治肺郁也有效？不知道逍遥散善于治疗五郁，并非只治肝经一部的郁结而已。况且佐以桔梗，疏散肺之邪气，加上黄芩泻肺之热，并且引导群药直入肺经，什么郁结不能宣散呢。所以壅塞通，稠浊化。
此症用宣肺散也很好。
柴胡、黄芩、紫菀（各二钱）、白芍（一两）、当归、麦冬（各五钱）、茯苓、白芥子（各三钱）、甘草、款冬花（各一钱）、紫苏（一钱）、辛夷（五分），水煎服。四剂痊愈。
There are cases where a person suddenly flows clear fluid from the nose. After a long time, it becomes runny nose; after even longer, it flows yellow and turbid substances, like pus or marrow, with an unbearable fishy and foul odor. If this persists for ten years, the person will die. This disease arises from excessive drinking and sleeping in the wind. Wind enters the Gallbladder (Dan, 胆), and the alcohol toxin within the Gallbladder cannot be excreted outward, thus transferring its heat to the Brain (Nao, 脑). The orifice of the Brain connects to the nose. How does the Qi of the Gallbladder connect to the Brain, and how does the Qi of alcohol enter the Gallbladder? Those who are skilled at drinking have naturally vigorous Gallbladder Qi and often shout loudly; therefore, alcohol Qi first enters the Gallbladder. When the Gallbladder cannot withstand the alcohol, failing to transform it promptly, fire toxins remain within. The Gallbladder belongs to Wood and most fears cold wind. External cold invasion makes internal heat more severe. The Gallbladder is Yang, and the head is also Yang. When the Gallbladder transfers heat upward to the head, and since the Brain is located within the head, which has no place to store heat, the heat enters upon encountering acupoints. Moreover, the Gallbladder and Brain are originally connected. The acupoints of the Brain are much larger than those of the Gallbladder, so the heat prefers to reside in the Brain rather than return to the Gallbladder. After residing in the Brain for a long time, seeking change due to extreme movement, it seeks an orifice to exit, following the path to the nose. Shallow fire toxins result in clear nasal discharge; deep fire toxins result in turbid discharge. The longer it lasts, the more it flows and the heavier the condition becomes. Eventually, there is no more discharge, and even the brain marrow is completely expelled, making death inevitable. Treatment targeting the Brain is feasible, but treating the Brain requires still treating the Gallbladder, which is a root-seeking treatment. Use Qu Yuan Tang (Cavern-Draining Decoction): Xin Yi (Magnolia Flower) (2 qian), Dang Gui (Angelica Sinensis Root) (2 liang), Chai Hu (Bupleurum Root) (1 qian), Chao Zhi Zi (Fried Gardenia Fruit) (3 qian), Xuan Shen (Scrophularia Root) (1 liang), Bei Mu (Fritillaria Bulb) (1 qian). Decoct in water and take orally. One dose reduces discharge; two doses reduce it further; three doses cure the disease completely.
Xin Yi enters the Gallbladder meridian best, guiding Dang Gui to tonify Brain Qi, and guiding Xuan Shen to resolve Brain Fire. Adding Chai Hu and Zhi Zi soothes stagnant heat in the Gallbladder, so the Gallbladder does not assist the fire and naturally benefits from qi tonification. Not directly stopping the nasal discharge, but clearing Brain Fire and benefiting Brain Qi is precisely the method to stop it. Since there is no original discharge in the nose, blocking the source upstream renders cutting off the downstream flow unnecessary. This is the divine efficacy of this treatment. Some doubt the large dosage of Dang Gui, unaware that when brain marrow is fully expelled, massive tonification is needed to generate Brain Qi. Xin Yi is a dispersing herb and should not be used long-term; thus, leveraging its guiding action, a large dose of Dang Gui is used to tonify the Brain and replenish essence, avoiding the need for later use. If Xin Yi is reduced later, heavy use of Dang Gui would be ineffective. This is the key to the sequence of medication, which must be understood. People suspect Dang Gui cannot be used in large amounts because they dislike its slippery nature interfering with the Spleen. However, one who suffers from direct brain marrow leakage surely has marrow that fails to transform into essence. If essence fails to transform, essence is scarce; if essence is scarce, it cannot distribute to the Large Intestine, leading to dryness. Therefore, using Dang Gui to moisten is exactly what is desired, leaving no cause for worry.
This condition can also be treated effectively with Tan Yuan Dan (Cavern-Exploring Pill).
Xin Yi (1 qian), Dang Gui (5 qian), Mai Dong (Ophiopogon Tuber) (2 liang), Fu Ling (Poria) (3 qian), Huang Qin (Scutellaria Root) (2 qian), Bai Shao (White Peony Root) (1 liang), Tian Hua Fen (Trichosanthes Root) (3 qian), Sheng Di (Rehmannia Root) (5 qian), Jie Geng (Platycodon Root) (2 qian). Decoct in water and take orally. Four doses cure completely.
Some people have clear nasal discharge persisting for a year without healing. This is Lung Qi deficiency and cold, not Brain Leakage (Nao Lou). Brain Leakage is synonymous with Nasal Pool (Bi Yuan). There are originally cold and hot syndromes, not solely caused by Gallbladder heat. However, for the same Nasal Pool, how to distinguish cold from hot? Generally, foul-smelling discharge indicates heat; clear, non-foul discharge indicates cold. Heat belongs to excess heat; cold belongs to deficiency cold. Here, only clear discharge without fishy odor indicates a deficiency-cold disease. Hot syndromes should use cooling herbs; cold syndromes should use mild-warm formulas. If all use dispersing herbs without tonification, Lung Qi is damaged, and Lung Metal becomes colder, causing more clear discharge. Use Wen Fei Zhi Liu Dan (Lung-Warming Discharge-Stopping Decoction): He Zi (Chebula Fruit) (1 qian), Gan Cao (Licorice Root) (1 qian), Jie Geng (Platycodon Root) (3 qian), Shi Shou Yu Nao Gu (Stonefish Brain Bone) (5 qian, calcined to retain character and ground into powder), Jing Jie (Schizonepeta Spike) (0.5 qian), Xi Xin (Asarum Root) (0.5 qian), Ren Shen (Ginseng Root) (0.5 qian). Decoct in water and mix with powder for oral administration. One dose stops the flow immediately; no further doses are needed.
This formula has a mild-warm aroma, naturally warming the Lung, while its nature carries dispersing properties, further expelling pathogens, hence achieving miraculous results. Some ask: Stonefish Brain Bone was used by ancients to treat internal-heat Nasal Pool as it is a cold-natured substance. Why use it for cold-syndrome Nasal Pool? It is unknown that Nasal Pool indeed has cold and hot syndromes, and Stonefish Brain Bone treats both. But hot syndrome discharge connects to the Brain, while cold syndrome discharge originates from the Lung. I use herbs entering the Lung meridian, all of mild-warm nature. Since the Lung is cold-cool, it resolves itself with mild-warmth. Assisted by Stonefish Brain Bone to block the path from the Brain, Brain Qi does not sink, and Lung Qi closes tighter. Thus, one dose stops the flow.
Some have nasal congestion, thick sticky turbid discharge for years. All assume it is Nasal Pool with fire knotting in the Brain. Who knows it is actually Lung Meridian stagnant fire not venting, resembling Nasal Pool but not being Nasal Pool. Stagnation diseases exist in all five Zang organs, not just Liver Wood. *Neijing* states: All Qi stagnations belong to the Lung. Lung Qi stagnation causes Qi obstruction; the nose is the gateway of the Lung Meridian. Thus, if Lung Qi is obstructed, nasal Qi is also obstructed. *Nan Jing* states: Severe Lung heat causes nasal discharge. The Lung is originally a clear-empty organ, most hating heat. Lung heat makes Lung Qi rough, and fluids in the Lung boil upward, condensing into discharge. Severe heat makes discharge yellow; extreme heat makes discharge turbid. Turbid,败坏 substances cannot remain in the clear-empty organ and must exit through the nasal gateway. Use Xiao Yao San (Free and Easy Wanderer Powder) with modifications.
Chai Hu (2 qian), Dang Gui (3 qian), Bai Zhu (Atractylodes Macrocephala Rhizome) (2 qian), Chen Pi (Citrus Peel) (0.5 qian), Gan Cao (1 qian), Huang Qin (1 qian), Fu Ling (2 qian), Bai Shao (3 qian), Bai Zhi (Angelica Dahurica Root) (1 qian), Jie Geng (3 qian), Ban Xia (Pinellia Tuber) (1 qian). Decoct in water and take orally. One dose brings relief; two doses bring further relief; eight consecutive doses cure completely.
This formula treats Liver Wood stagnation. Why is it effective for Lung stagnation? Unknown is that Xiao Yao San excels at treating Five Stagnations, not merely Liver Meridian stagnation. Furthermore, assisted by Jie Geng to disperse Lung pathogens, and Huang Qin to drain Lung heat, guiding all herbs directly into the Lung Meridian, what stagnation cannot be vented? Thus, congestion clears, and turbidity transforms.
Using Xuan Fei San (Lung-Ventilating Powder) is also excellent for this condition.
Chai Hu, Huang Qin, Zi Wan (Aster Root) (2 qian each), Bai Shao (1 liang), Dang Gui, Mai Dong (5 qian each), Fu Ling, Bai Jie Zi (White Mustard Seed) (3 qian each), Gan Cao, Kuan Dong Hua (Farfusa Flower) (1 qian each), Zi Su (Perilla Leaf) (1 qian), Xin Yi (0.5 qian). Decoct in water and take orally. Four doses cure.
