一妇呕吐半月，诸药不效，势已危矣，但气未绝耳。诊之脉俱内掉，左手尺中全无。曰

暴发性呕吐，多由饮食损伤引起。若食滞在上脘，通过一次呕吐即可痊愈，可用平胃散加半夏，或藿香正气散。霍乱引起的吐泻，若伴有手足冰冷，轻症用理中汤，重症用四逆汤。若仅呕吐且不止，用二陈汤加姜汁；若无效，再加丁香；若温服后仍不愈，恐怕是虚中有火，可加炒黑栀子仁、人参，或将沉香、乌药研为细末，取生姜三片，用淡盐水擦拭后，蘸药末含化。若属寒证，则多吐出水和食物，腹痛不想吃东西，用理中汤；若属热证，则多呕吐，身体发热如火，呕吐时蛔虫随之而出，用理中汤加乌药、黄连。
霍乱吐泻，呕吐以消除痰浊为主，腹泻以调和脾胃为主，腹痛以温中为主。
凡是呕吐病症，如早晨吃的饭到中午才吐，午前吃的饭到晚上才吐，呕吐时好像没有阻碍一样，这是胃气大虚的表现。可用二陈汤加丁香、槟榔、枳壳，以温降之法治疗；若不用槟榔、枳壳，可用黄连五厘、吴茱萸二厘，加生姜煎服。服用两帖后加入人参。
呕吐兼有恶心者，恶心属于火邪，宜用二陈汤加黄连、吴茱萸；只有恶心却不出声的，属于虚证，宜用温法，不宜用其他方法。
凡是呕吐，使用二陈汤，热证加山栀，寒证加炮姜，肌肤发热烦躁作渴，加葛根；呕吐后的调理，用六君子汤。
呕吐兼有腹泻者，呕吐时蛔虫出者，是脾有湿热，用理中汤加乌梅一枚、黄连三厘。
仅呕吐而不恶心，是三厘（此处原文可能有误，结合语境应为药量或指代轻微症状，依原文直译），养胃降火，其气得以下降而自愈。自吐而不恶心的，这叫假吐，热在胃脘；真吐必定伴随恶心。
呕吐，物出而无声，有虚证和实证之分：呕吐且足冷脉细的是虚证，呕吐且身热脉实的是实证。挟带食物停滞、停聚痰饮，用二陈汤二钱，姜三片，水煎服。
呕吐兼有心痛，按火邪治疗。治疗方法有虚实不同，口吐清水按虫积治疗。呕吐因胃有热邪，喜冷饮，寸脉紧数，用竹茹汤治疗。呕吐无定时，寸脉沉迟伏，用橘皮汤主治，陈皮、半夏、干姜等。
干霍乱，用盐水探喉催吐，切勿给予米汤饮料，否则会助长邪气导致急速死亡。呕吐且胸胁疼痛，脉洪大而硬，大便闭塞，若冷汗如水，烦躁，大便闭塞，脉搏摸不到，属不治之症。
呕吐且四肢冰冷，尺脉短少，六脉浮大无根，大多凶险少吉。
既呕又吐，用槟榔下气治疗两三次仍不愈，属不治之症。
呕吐且浑身胀满，是肝气实证，属不治之症。
呕吐且无脉搏，属不治之症。
呕吐且有气出无气入，属不治之症。

一位妇女呕吐半个月，各种药物无效，病情已危重，但气息未绝。诊察发现脉象俱内动，左手尺部完全无脉。说：这唯独可以生还，因为阳气未绝，所以左尺脉独存。用沉香、乌药等分，人参、甘草减半，研为细末，生姜切片用淡盐腌渍，蘸药末含化，吐出痰液约一碗后痊愈。
一人身体肥大，每天吃一顿鸡，只下午呕吐清水，晚上吃一顿肉，才安稳。诊察发现，寸脉比尺脉大数倍，尺脉沉涩，这是阴盛阳隔，上焦火盛故能进食，丹田虚寒故呕吐。用半夏一钱，沉香三分，栀子五分，人参、炮姜各一钱，附子三分，温下清上而痊愈。
一位孕妇呕吐逆乱，滴水不进，胁下疼痛剧烈甚至厥逆，脉象左关尺洪大，右关平和，右尺革脉。这是因为肾燥不能生木，木枯生火以侮脾土，脾挟肝邪，上行于肺，所以呕吐而痛。若无胎儿，只需瓜蒌仁、天冬麦冬、半夏、柴胡、肉桂即可痊愈；现在有胎不宜，用地黄以滋肾血，当归身使血归肝以制火，白芍除土中之木邪，甘草缓上炎之火，砂仁理气安胎，黄芩平伤肺之邪火，大枣调和脾胃。服用两三帖后，火势稍平，改用杜仲、续断、黄芩、黄连、苏梗、桔梗、炮姜，收敛火势安胎。坚守此方不变，自然厥逆停止而痊愈。要知道呕吐损伤脾胃，则当归、地黄均在禁忌之列，如今则是水枯火炽，所以用滋阴药，培补根本。
一人吐泻腰痛，想吃东西却吃不下。这是木邪乘克脾土，胃火炽盛而心中嘈杂似饥。火在中焦，上干于肺而呕吐，下流大肠而腹泻，肺与大肠互为表里，大肠既不固摄，肺又不生肾，则水伤而肾痛。用苍术、白术以和胃，茯苓、栀子平火。茯苓、山药补脾肺，白芍平肝，苏梗通气，则火平湿去而安宁。
Sudden vomiting is caused by dietary injury. If food stagnates in the upper jiao (upper burner), it can be cured by one episode of vomiting; use Pingwei San (Stomach-Ping Powder) with Banxia (Pinellia Rhizome), or Huoxiang Zhengqi San (Agaricus Powder for Regulating Qi). For cholera-like syndrome with vomiting and diarrhea, if accompanied by cold hands and feet, use Lizhong Tang (Middle-Regulating Decoction) for mild cases, and Sini Tang (Recover the Lost Decoction) for severe cases. If there is only continuous vomiting, use Erchen Tang (Two-Aged Decoction) with Jiangzhi (Ginger Juice); if ineffective, add Dingxiang (Clove); if warming does not cure, suspect deficiency with internal heat, add Chao Hei Zhiren (Charred Gardenia Seed) and Renshen (Ginseng), or grind Chenxiang (Aquilaria Wood) and Wuyao (Lindera Root) into powder, take three slices of Shengjiang (Fresh Ginger), wipe with light salt water, dip in the powder, and dissolve in the mouth. If it is a cold pattern, there is much vomiting of water and food, abdominal pain, and loss of appetite; use Lizhong Tang. If it is a heat pattern, there is much retching, body heat like fire, and expulsion of roundworms during vomiting; use Lizhong Tang with Wuyao and Huanglian (Coptis Rhizome).
For cholera-like vomiting and diarrhea, treat vomiting primarily by resolving phlegm, diarrhea primarily by harmonizing the middle, and abdominal pain primarily by warming the middle.
Vomiting immediately after eating is due to Qi deficiency; it is appropriate to tonify the Fire of the Mingmen (Gate of Life).
In all vomiting diseases, if food eaten in the morning is vomited at noon, or food eaten before noon is vomited at night, and vomiting occurs without obstruction, this indicates severe deficiency of Stomach Qi. Use Erchen Tang with Dingxiang, Binglang (Areca Seed), and Zhike (Aurantium Fruit) to warm and descend; if Binglang and Zhike are not used, use Huanglian (5 li) and Wuyu (Evodia Fruit, 2 li), decocted with Shengjiang. After two doses, add Renshen.
When vomiting is accompanied by nausea, nausea belongs to Fire; use Erchen Tang with Huanglian and Wuyu. Only when there is nausea but no sound, it is a deficiency pattern; use warming methods, not others.
In all vomiting cases where various medicines are ineffective, use Sugeng Tang (Perilla Stem Decoction) with ground Binglang and Zhike.
In all vomiting cases, use Erchen Tang; add Shanzhi (Gardenia Fruit) for heat, Paogjiang (Prepared Ginger) for cold, and Gegen (Kudzu Root) for skin fever, irritability, and thirst. For post-vomiting regulation, use Liujunzi Tang (Six-Gentlemen Decoction).
When vomiting is accompanied by diarrhea, or expulsion of roundworms during vomiting, it indicates damp-heat in the Spleen; use Lizhong Tang with one Wumei (Mume Fruit) and 3 li of Huanglian.
Only vomiting without nausea involves 3 li (likely a textual error or specific minor dosage reference in original context, translated literally as per instruction to not add content), nourishing the Stomach and descending Fire, allowing Qi to descend and self-healing. Vomiting without nausea is called false vomiting, with heat in the Wei (Stomach); true vomiting must be accompanied by nausea.
Vomiting, where material exits without sound, can be deficiency or excess: vomiting with cold feet and fine pulse is deficiency; vomiting with body heat and excess pulse is excess. Accompanied by food stagnation or retained phlegm, use Erchen Tang (2 qian), Shengjiang (3 slices), decocted in water.
Vomiting accompanied by heart pain is treated as Fire. Treatment differs by deficiency/excess; vomiting clear water is treated as parasitic accumulation. Vomiting due to Heat pathogen in the Stomach, preferring cold drinks, with tight and rapid Cun (inch) pulse, is treated with Zhuru Tang (Bamboo Shaving Decoction). Vomiting without fixed time, with deep, slow, and hidden Cun pulse, is primarily treated with Jupi Tang (Tangerine Peel Decoction), using Chenpi (Tangerine Peel), Banxia, Ganjiang (Dried Ginger), etc.
For Ganhuoluan (Dry Cholera), induce vomiting by probing the throat with salt water; never give rice drink, as it will assist the pathogen and cause rapid death. Vomiting with chest and hypochondriac pain, with surging and hard pulse, and constipation, if accompanied by cold sweat like water, irritability, constipation, and absent pulse, is untreatable.
Vomiting with cold limbs, short Chi (cubit) pulse, and floating, large, rootless six pulses indicate mostly bad prognosis with little hope.
Vomiting with constipation indicates loss of Stomach Qi transmission; it is untreatable.
Both vomiting and retching, if Binglang fails to descend Qi after two or three treatments, is untreatable.
Vomiting with whole-body distension indicates Liver Qi excess; it is untreatable.
Vomiting with absent pulse is untreatable.
Vomiting with exhalation but no inhalation is untreatable.
Case Record 1: A woman vomited for half a month with no effect from various medicines, condition critical but breath unextinguished. Pulse was internally trembling, with no pulse at all in the left Chi position. Said: This alone can survive because Yang Qi is not extinguished, so the left Chi pulse remains alone. Used Chenxiang and Wuyao in equal parts, Renshen and Gancao (Licorice) halved, ground into powder. Shengjiang sliced and pickled in light salt, dipped in powder and dissolved in mouth. Expelled about a bowl of phlegm and recovered.
Case Record 2: A person with a large body ate chicken once daily, only vomiting clear water in the afternoon, and felt secure after eating meat at night. Pulse showed Cun several times larger than Chi, Chi was deep and choppy. This is Yin excess blocking Yang, excessive Fire in the Upper Jiao allowing eating, and deficiency-cold in the Dantian causing vomiting. Used Banxia (1 qian), Chenxiang (3 fen), Zhizi (5 fen), Renshen and Paogjiang (1 qian each), Fuzi (Aconite Root, 3 fen). Cured by warming below and clearing above.
Case Record 3: A pregnant woman suffered severe vomiting and regurgitation, unable to swallow even water, with severe hypochondriac pain leading to syncope. Pulse: Left Guan and Chi were surging; Right Guan was peaceful; Right Chi was革 (drum-taut). This is due to Kidney dryness failing to generate Wood, Wood drying and generating Fire to insult Spleen Earth, Spleen carrying Liver pathogen upward to Lung, causing vomiting and pain. Without pregnancy, Guaren (Melon Seed), Tianmendong (Asparagus Tuber), Maidong (Ophiopogon Tuber), Banxia, Chaihu (Bupleurum Root), Rougui (Cinnamon Bark) would cure it; now with pregnancy, these are unsuitable. Used Shengdi (Rehmannia Root) to nourish Kidney Blood, Dangguishen (Angelica Sinensis Root Heart) to return blood to Liver to control Fire, Baishao (White Peony Root) to remove Wood from Earth, Gancao to缓 (slow/relax) flaming Fire, Sharen (Amomum Fruit) to regulate Qi and calm fetus, Huangqin (Scutellaria Root) to calm Fire injuring Lung, Dazao (Jujube) to harmonize Middle. After 2-3 doses, Fire slightly calmed, then used Duzhong (Eucommia Bark), Xuduan (Dipsacus Root), Qin, Lian (Coptis), Sugeng, Jiegeng (Platycodon Root), Paogjiang to gather Fire and calm fetus. Adhere to this without change, syncope stops and recovers. Note that vomiting injures Spleen and Stomach, making Danggui and Dihuang generally contraindicated; here, Water is dry and Fire blazing, so Yin-nourishing herbs are used to cultivate the root.
Case Record 4: A person had vomiting, diarrhea, and lower back pain, wanting to eat but unable. This is Wood pathogen attacking Earth, Stomach Fire blazing causing heart palpitations resembling hunger. Fire in Middle Jiao affects Lung upward causing vomiting, flows to Large Intestine downward causing diarrhea. Lung and Large Intestine are exterior-interior; since Large Intestine is not firm, Lung cannot generate Kidney, Water is injured causing Kidney pain. Used Cangzhu (Atractylodes Lancea) and Baizhu (Atractylodes Macrocephala) to harmonize Stomach, Ling (Poria) and Zhizi to calm Fire. Fuling (Poria), Shanyao (Dioscorea Rhizome) tonify Spleen and Lung, Baishao calms Liver, Sugeng regulates Qi, then Fire calms, Dampness leaves, and peace is restored.
