耳中出血，将龙骨研末吹入鼻腔即可止血。若左关脉象弦而洪大，使用柴胡清肝散。尺脉或躁动不安或虚弱无力，使用六味地黄丸。
口鼻出血，都属于上实下虚，气机只有上升没有下降，血液随着气机上逆，从上部孔窍溢出。治疗应当顺其气机，气降则血回归经脉。适宜用苏子降气汤，加入人参、阿胶各一钱，配合服用下养正丹。也有因气虚不能统摄血液的，其脉象必定微弱虚软，精神疲惫，适宜用独参汤，或者人参饮子、团参丸。上焦壅热导致的吐血，脉象洪大弦长，重按有力，精神不疲倦，或者感觉胸中满痛，或者血色紫黑成块的，使用生地黄、赤芍、当归、牡丹皮、荆芥、阿胶、滑石、大黄、玄明粉、桃仁泥这类药物，通过大便引导排出瘀血，这是釜底抽薪的方法。血液从下部排出为顺证，从上部溢出为逆证，所有血液上溢的病证，如果不是脾虚泄泻、身体极度消瘦无法承受攻伐的患者，都应当用醋制大黄，配合生地黄汁，以及桃仁泥、牡丹皮等药物，引入血分，使血液下行，将逆证转为顺证，这是妙法。不了解这一点而整天从事于黄芩、黄连、栀子、黄柏这类寒凉药物，辅助四物汤来行血，会导致气血俱伤，脾胃两败。如今医生治疗血证，怎么会有痊愈的呢？血液下行之后，使用薏苡仁（多用）、百合、麦门冬、鲜地骨皮。咳嗽口渴加枇杷叶、五味子、桑根白皮。有痰加贝母。这些都是气薄味淡的药物，属于西方兑金的本药，顺着病势衰退而减少邪气，自然不再复发，对于虚劳证尤其适宜。急于止血的，使用血余灰二钱，用白开水化开阿胶二钱，加入童便、生藕汁、刺蓟汁、生地黄汁各一杯，仍用好墨磨浓黑，顿服温热的药液。胸中烦热，吐血不止，口舌干燥，头疼，使用石膏散。冒雨受湿，郁结在经络，血液溢出妄行，从鼻子流出则为鼻衄。鼻衄走清道，吐血走浊道。血液流入胃脘，令人吐血。使用肾着汤，头疼加川芎，最能止住浴室中引发的鼻衄。暑天吐血，病患口渴面垢，头晕干呕，煎煮茅花灯心麦门冬汤，仍加入藕节汁、侧柏叶汁、茅根汁少许、生姜汁少许、生蜜少许，调服五苓散。血止后用生地黄、当归、牡丹皮、赤芍药、百草霜末，煎服一二帖，然后用黄耆六一汤调理。怒气伤肝的，唇青面黑，当用鸡苏丸，煎四物汤吞服，并用十四友丸、灯心麦门冬汤吞服，因为其中含有理肝的药物。打扑损伤导致吐血，先用藕节汁、侧柏叶汁、茅根汁、韭汁、童便磨墨汁、化开的阿胶来止血。然后用川芎、当归、白芍药、百合、荆芥穗、阿胶、牡丹皮、紫金藤、大黄、滑石、红花煎汤，调服番降香末、白芨末。戴复庵先用苏合香丸，然后用黑神散和小乌沉汤，用童便调治。劳心过度吐血，用莲心五十粒，糯米五十粒，研末用温酒调服，以及天门冬汤。劳力太过，吐血不止，用苏子降气汤加人参、阿胶，用猪肝煮熟，蘸白芨末食用。吐血久不止，用松花散、百花煎，并常服大阿胶丸。未见效，用伏龙肝二钱，米饮调下，迅速止血。或者是饮酒之后，闷吐之时，血从吐后出，或因吃辛辣热物而得吐血之证，名叫肺疽。宜用大蓟散。古方用红枣烧存性，百药煎等分为末，米饮调服二钱。饮酒伤胃吐血，用理中汤加金钩子、干葛、茅花。酒色过度，饥饱失调吐血的有效方剂，用枇杷叶、款冬花、北紫菀、杏仁、鹿茸、桑白皮、木通、大黄为末，炼蜜为丸，噙化。内损吐血下血，或者饮酒太过，劳伤于内，血液妄行，流出如涌泉，口鼻皆流，片刻不救即死。用侧柏叶蒸焙一两半，荆芥穗烧灰，人参各一两，为细末，加入飞罗面一钱，新汲水调如稀糊，不拘时候啜服。伤胃吐血，因饮食太饱之后，胃中冷不能消化，便烦闷，强呕吐，使所食之物与气共上冲蹙，因伤裂胃口，吐血色鲜正赤，腹亦绞痛，自汗，其脉紧而数者，为难治也。适宜用理中汤加川芎、干葛各半钱，或者只根据理中本方，加川芎、扁豆尤好，不必用干葛。如果口渴甚用葛根，丸剂则用白术丸。《曹氏必用方》说：吐血须煎干姜、甘草作汤与服，或者四物理中汤亦可，如此无不愈者。如果服生地黄、竹茹、藕汁，去生便远。《三因方》说：理中汤能止伤胃吐血，以其方最理中脘，分利阴阳，安定血脉。按患者果身受寒气，口受冷物，邪入血分，血得冷而凝，不归经络而妄行者，其血必黯黑，其色必白而夭，其脉必微迟，其身必清凉，不用姜桂而用凉血之剂殆矣。临病之工，宜详审焉。有时或吐血两口，随即无事，数日又发，经年累月不愈者，宜黑神散和小乌沉汤常服。吐血人多发渴，名为血渴，十全大补汤，或者黄耆、人参、五味子、地黄、麦门冬、葛根、枇杷叶，量胃气虚实用之。吐甚头晕，发为寒热者，降气汤合四物汤各半帖，加阿胶一钱。若单发热者，茯苓补心汤。吐血之后有潮热咳嗽，脉洪大而数，五至以上不可治也。《金匮方》，心气不足，吐血、衄血，泻心汤主之。大黄二两，黄连、黄芩各一两，水三升，煮取一升顿服之。此正谓心手少阴经之阴气不足，本经之阳亢甚无所辅，肺肝俱受其火而病作，以致阴血妄行而飞越，故用大黄泄去亢甚之火，黄芩救肺，黄连救肝，使之和平，则阴血自复而归经矣。云岐子加生地，名犀角地黄汤。又说：吐血不止，柏叶汤主之。柏叶、干姜各二两，艾三把，以水五升，取马通汁一升，合煮取一升，分温再服。凡吐血不已，则气血皆虚，虚则生寒，是故用柏叶，柏叶生而西向，乃禀兑金之气而生，可制肝木，木主升，金主降，取其升降相配，夫妇之道和则血得以归脏于肝矣，故用是为君。干姜性热，止而不走，用补虚寒之血。艾叶之温，能入内而不炎于上，可使阴阳之气反归于里，以补其寒，用二味为佐。马通者，为血生于心，心属午，于是用午兽之通，主降火消停血，引领而行为使。仲景治吐血，唯此二方，可以为准绳，触类而长之。
Bleeding from the ears can be stopped immediately by blowing calcined Longgu (Fossilia Ossis Mastodi, Dragon Bone) powder into the nasal cavity. If the pulse at the left Guan position is wiry and surging, use Chaihu Qinggan San (Bupleurum Liver-Clearing Powder). If the Chi pulse is either restless or weak, use Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill).
Bleeding from the mouth and nose is all related to excess in the upper jiao and deficiency in the lower jiao, with qi ascending without descending, causing blood to follow the qi upward and escape through the upper orifices. The treatment principle should be to smooth the qi; when qi descends, blood returns to its vessels. It is appropriate to use Suzi Jiangqi Tang (Perilla Seed Qi-Descending Decoction), adding Renshen (Ginseng Radix) and Ejiao (Donkey-hide Gelatin) each at one qian, along with Xiayangzheng Dan (Lower-Nourishing Uprightness Pill). There are also cases where qi deficiency fails to control the blood; the pulse will necessarily be weak, thready, and soft, with mental fatigue. In such cases, Dushen Tang (Single Ginseng Decoction), or Renshen Yinzi (Ginseng Drink), or Tuanshen Wan (Round Ginseng Pill) are appropriate. For hematemesis caused by heat congestion in the upper diaphragm, with a pulse that is surging, large, wiry, and long, forceful upon pressure, unweary spirit, or a sensation of fullness and pain in the chest, or purple-black clots in the blood, use Shengdihuang (Rehmanniae Radix), Chishao (Paeoniae Radix Rubra), Danggui (Angelicae Sinensis Radix), Mudanpi (Moutan Cortex), Jingjie (Schizonepetae Spica), Ejiao, Huashi (Talcum), Dahuang (Rhei Radix et Rhizoma), Xuanmingfen (Natrii Sulfas Exsiccatus), and Taoren Ni (Persic Semen Paste), etc., to guide the blood out through the bowels. This is the method of "removing firewood from under the cauldron." Blood exiting from below is a favorable sign (Shun), while bleeding from above is unfavorable (Ni). For all conditions of blood overflowing upward, unless the patient has spleen deficiency with diarrhea and extreme emaciation unable to tolerate purgation, one should use vinegar-processed Dahuang, mixed with Shengdihuang juice, as well as Taoren Ni, Mudanpi, etc., to enter the blood level, causing the blood to descend and turning the unfavorable condition into a favorable one. This is a subtle method. Those who do not understand this but daily engage in using Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Zhizi (Gardeniae Fructus), and Huangbai (Phellodendri Cortex), assisting Siwu Tang (Four Substances Decoction), will damage both qi and blood, leading to the failure of the spleen and stomach. How can there be any survivors among those treated by physicians today for blood disorders? After the blood has descended, use Yiyiren (Coicis Semen) (use in large amounts), Baihe (Lilii Bulbus), Maimendong (Ophiopogonis Radix), and Xian Digupi (Fresh Lycii Cortex). Add Pipaye (Loquat Leaf), Wuweizi (Schisandrae Fructus), and Sangbaipipi (Mori Cortex) for cough and thirst. Add Beimu (Fritillariae Bulbus) for phlegm. These herbs have thin qi and light taste, being the fundamental medicines of the West Metal element. By reducing pathogenic factors according to their decline, recurrence will naturally cease; this is especially suitable for Xu Lao (Consumption) syndromes. To stop bleeding urgently, use two qian of Xueyu Hui (Ash of Human Hair), dissolve two qian of Ejiao in plain water, add one cup each of Tongbian (Infant Urine), Sheng Ou Zhi (Fresh Lotus Rhizome Juice), Ciji Zhi (Sonchii Juice), and Shengdihuang juice. Grind high-quality ink into a thick black liquid, mix well, and take warm in one dose. For irritability in the chest, continuous hematemesis, dryness of the mouth and tongue, and headache, use Shigao San (Gypsum Powder). For blood溢 (overflowing) due to rain exposure and dampness stagnating in the meridians, manifesting as epistaxis, note that epistaxis travels through the clear pathways, while hematemesis travels through the turbid pathways. If blood flows into the stomach, it causes hematemesis. Use Shen Zhuo Tang (Kidney-Dampness Decoction); add Chuanxiong (Ligustici Chuanxiong Rhizoma) for headache. This is most effective for stopping epistaxis occurring in bathrooms. For hematemesis in summer, where the patient has thirst, greasy face, dizziness, and dry retching, decoct Maodeng Xin Maimendong Tang (Equisetum, Centella, and Ophiopogon Decoction), adding Ou Jie Zhi (Lotus Node Juice), Ce Bai Ye Zhi (Platycladi Cacumen Juice), Mao Gen Zhi (Imperatae Rhizoma Juice), a little Shengjiang (Zingiberis Rhizoma Recens) juice, and a little Sheng Mi (Raw Honey). Mix with Wuling San (Five-Ingredient Powder with Poria). After bleeding stops, use Shengdihuang, Danggui, Mudanpi, Chishao Yao (Paeoniae Radix Rubra), and Baicao Shuang Mo (Powder of Hundred Herbs Ash), decocted and taken for one or two doses, then regulate with Liuyi Tang (Honeydew Melon and Talcum Powder). For liver injury due to anger, presenting with cyanotic lips and dark face, use Jisu Wan (Elsholtzia Pill), swallowed with Siwu Tang decoction, and also with Shisi You Wan (Fourteen Friends Pill) and Dengxin Maimendong Tang (Juncus and Ophiopogon Decoction), as they contain herbs that regulate the liver. For hematemesis due to bruising and trauma, first stop bleeding with Ou Jie Zhi, Ce Bai Ye Zhi, Mao Gen Zhi, Jiu Zhi (Leek Juice), Tongbian mixed with ink juice, and dissolved Ejiao. Then decoct Chuanxiong, Danggui, Baishao Yao (Paeoniae Radix Alba), Baihe, Jingjie Sui (Schizonepetae Spica), Ejiao, Mudanpi, Zijin Teng (Akebia Caulis), Dahuang, Huashi, and Honghua (Carthami Flos) in water, and take with Fan Jiangxiang Mo (Sappan Wood Powder) and Baiji Mo (Bletillae Rhizoma Powder). Dai Fu'an first used Suhexiang Wan (Styrax Pill), then treated with Heishen San (Black Divine Powder) and Xiao Wuchen Tang (Minor Dark Stagnation Decoction), regulated with Tongbian. For heart labor-induced hematemesis, use fifty Lianxin (Nelumbinis Plumula) and fifty Nuomi (Glutinous Rice), grind into powder, and take with warm wine, along with Tianmendong Tang (Asparagi Decoction). For excessive physical labor causing continuous hematemesis, use Suzi Jiangqi Tang added with Renshen and Ejiao; eat cooked pork liver dipped in Baiji powder. For chronic hematemesis that does not stop, use Songhua San (Pine Pollen Powder) and Baihua Jian (Hundred Flowers Decoction), and frequently take Da Ejiao Wan (Large Donkey-hide Gelatin Pill). If ineffective, use two qian of Fulonggan (Ustulatum Cao), taken with rice drink, to stop bleeding quickly. Or, after drinking alcohol or during stifling vomiting, if blood appears after vomiting, or if hematemesis results from consuming spicy and hot foods, it is named Fei Ju (Lung Abscess). Use Daji San (Greater Thistle Powder). Ancient formulas use Hongzao (Jujubae Fructus) charred to retain its nature, mixed equally with Baiyaojian (Fermented Medicated Leaven), ground into powder, and taken with rice drink at two qian. For hematemesis due to alcohol damaging the stomach, use Lizhong Tang (Regulate the Middle Decoction) added with Jingouzi (Uncariae Ramulus cum Uncis), Gange (Puerariae Radix), and Maohua (Equiseti Herba). For hematemesis due to excessive alcohol and sexual activity, or irregular eating, an effective formula uses Pipaye, Kuandonghua (Kolkwitziae Flos), Beiziwan (Asteris Radix), Xingren (Armeniacae Semen Amarum), Lurong (Cervi Cornu Degelatinatum), Sangbaipi (Mori Cortex), Mutong (Akebiae Caulis), and Dahuang, ground into powder, made into pills with refined honey, and held in the mouth to dissolve. For internal injury causing hematemesis and hematochezia, or excessive drinking, internal labor injury causing reckless blood flow, gushing like a spring, flowing from mouth and nose, which leads to death if not saved promptly: use Ce Baiye (Platycladi Cacumen) steamed and dried, one liang and half; Jingjie Sui burned to ash, one liang; Renshen, one liang. Grind into fine powder, add one qian of Feiluo Mian (Fine Wheat Flour), mix with fresh well-water into a thin paste, and sip at any time. For stomach injury hematemesis, caused by overeating leading to cold stomach inability to digest, resulting in restlessness, forced vomiting, causing food and qi to rush upward and crush, thereby tearing the stomach opening, presenting with bright red blood, abdominal cramping pain, spontaneous sweating, and a tight and rapid pulse, it is difficult to treat. Use Lizhong Tang added with Chuanxiong and Gange, half qian each; or simply use the base Lizhong Tang added with Chuanxiong and Bian Dou (Phaseoli Semen), which is better, without Gange. If thirst is severe, use Ge Gen (Puerariae Radix); for pills, use Baizhu Wan (Atractylodis Macrocephalae Pill). *Cao Shi Bi Yong Fang* states: For hematemesis, one must decoct Ganjiang (Zingiberis Rhizoma) and Gancao (Glycyrrhizae Radix) to make a decoction to take, or Siwu Lizhong Tang is also acceptable; thus, there is no case that does not heal. If Shengdihuang, Zhuru (Bambusae Caulis in Taenia), or Ou Zhi are used, healing is far away. *San Yin Fang* states: Lizhong Tang can stop stomach-injury hematemesis because it best regulates the middle jiao, separates yin and yang, and stabilizes the blood vessels. If the patient indeed suffers from external cold and ingested cold items, with pathogens entering the blood level, blood congealing due to cold, failing to return to vessels and flowing recklessly, the blood will be dark black, complexion pale and lifeless, pulse micro and slow, body cool. Using cooling blood agents instead of Jiang Gui (Zingiberis Rhizoma and Cinnamomi Cortex) would be dangerous. Physicians attending to diseases should examine carefully. Sometimes bleeding occurs twice, then resolves, only to recur days later, persisting for years without healing; Heishen San and Xiao Wuchen Tang should be taken regularly. Hematemesis patients often develop thirst, named Xue Ke (Blood Thirst). Use Shiquan Dabu Tang (Perfect Great Tonifying Decoction), or Huangqi (Astragali Radix), Renshen, Wuweizi, Dihuang, Maimendong, Gegen, Pipaye, dosed according to stomach qi deficiency or excess. Severe vomiting with dizziness, developing chills and fever: use Jiangqi Tang combined with Siwu Tang, half a dose each, plus one qian of Ejiao. If only fever occurs, use Fuling Buxin Tang (Poria Heart-Nourishing Decoction). Post-hematemesis tidal fever and cough with a surging, large, and rapid pulse exceeding five beats per breath are untreatable. *Jin Gui Fang*: Insufficient heart qi causing hematemesis and epistaxis is primarily treated with Xiexin Tang (Drain the Heart Decoction). Dahuang two liang, Huanglian and Huangqin one liang each. Boil in three sheng of water to obtain one sheng, take in one dose. This refers precisely to insufficient yin qi of the Hand-Shaoyin Heart Meridian, with excessive yang in the same meridian lacking support, causing Lung and Liver to suffer from fire and disease, leading to reckless flying of yin blood. Thus, Dahuang is used to drain excessive fire, Huangqin saves the Lung, and Huanglian saves the Liver, bringing them to harmony, so yin blood naturally recovers and returns to the vessels. Yun Qizi adds Shengdi, naming it Xijiao Dihuang Tang (Rhino Horn and Rehmannia Decoction). Also stated: For continuous hematemesis, Baiye Tang (Platycladus Decoction) is primary. Baiye and Ganjiang two liang each, Aiye (Artemisiae Argyi Folium) three handfuls. Boil in five sheng of water, add one sheng of Matong (Equi Feces), boil together to obtain one sheng, take warm in two divided doses. Whenever hematemesis does not cease, qi and blood both become deficient; deficiency generates cold. Therefore, Baiye is used. Baiye grows facing west, inheriting the Qi of Dui Metal, which can restrain Liver Wood. Wood governs ascent, Metal governs descent; taking advantage of this ascending-descending pairing, the husband-wife relationship harmonizes, allowing blood to return to the Liver organ. Thus, it is used as the Sovereign herb. Ganjiang is hot in nature, stopping movement without wandering, used to tonify blood deficiency-cold. Aiye's warmth enters internally without flaring upward, allowing yin and yang qi to return inward to supplement cold; these two are used as Ministers. Matong is used because blood is generated by the Heart, which corresponds to Wu (Noon); thus, the excrement of the Wu animal (horse) is used to descend fire and resolve stagnant blood, leading the action as the Envoy. Zhang Zhongjing's treatments for hematemesis rely on these two formulas as the standard; apply this principle to extend to other cases.
