程氏有少妇，病小腹痛，吐痰多呕清水，发热泄泻，肌削而屏饔飧，六脉沉细弦数。曰∶此积饮也，法当
发其积，而病可除。第病久而孱，伐无太过，剂以和中去湿。小腹大痛而昏，既则呕吐盈盆，沉沉皆绿水。众
异曰∶何为有此？桥曰∶吾固以为湿也。盖地下湿则生苔，其缘同，寻无恙。（同上。）
罗练年近壮，病中脘疼痛，连背胁及心间，吐清水，久之痛甚，如 刃，人事昏昏。族医技穷，谓六脉绝
矣。桥后至则曰∶停饮也。痛甚故脉伏，非绝也。遂以温补之剂投之，一服而脉见，再服而愈。（《太函集》。）
徐灵胎曰∶凡病必有邪，如人病汤水下咽，少顷即倾囊涌出者，此乃胃中积水寒饮，故食入即拒。法当扶
阳涤饮，驱开寒邪，然后补其中气。亦必兼涤饮之药，不可竟用参、术补住寒饮。若无邪而现症若此，乃胃绝
之征，亦不必治矣。洞庭一金姓者患呕吐症，其先人与叶氏甚相契，叶氏竭力治之年余，而病者几殆，因求治
程氏家中有一位年轻妇人，患小腹部疼痛，痰多且呕吐清水，伴有发热、腹泻，肌肉消瘦，无法进食，六脉呈现沉、细、弦、数的脉象。医生（魏之琇/桥）说：这是停饮（水液代谢障碍导致的水湿停聚），治疗法则应当攻逐体内的积饮，病就可以消除。只是病人患病日久且体质虚弱，攻伐不宜太过，处方以调和中焦、祛除湿气为主。服药后小腹剧烈疼痛并出现昏厥，随后呕吐出满盆液体，全是绿色的水样物。众人感到惊异，问：为什么会这样？医生说：我本来就知道是湿邪所致。就像地下潮湿就会长苔藓一样，道理是相同的，寻找其根源便无大碍。（同上。）
罗练年近壮年，患中脘部疼痛，牵连背部、胁肋及心窝处，呕吐清水，时间久了疼痛加剧，如刀割一般，神志昏沉迷糊。家族医生医术穷尽，认为六脉已经断绝。魏之琇到达后说：这是停饮。因为疼痛剧烈所以脉象伏匿不见，并非真的断绝。于是给予温补的药剂服用，一服后脉象显现，再服后痊愈。（《太函集》。）
徐灵胎评论说：凡是疾病必有邪气存在。比如有人喝下汤药，片刻之后便全部涌吐出来，这是因为胃中有积水寒饮，所以食物进入即被排斥。治疗法则应当扶助阳气、涤除饮邪，驱散寒邪，然后补益中气。也必须兼用涤除饮邪的药物，不能仅仅使用人参、白术等药物来补住寒饮。如果没有邪气而症状如此，那是胃气绝灭的征象，也不必治疗了。洞庭湖地区有一个姓金的人患呕吐症，他的祖先与叶天士非常相契，叶天士竭尽全力治疗了一年多，病人几乎危殆，于是求治于……
A young woman in the Cheng family suffered from lower abdominal pain, excessive phlegm production, vomiting of clear fluid, fever, diarrhea, emaciation, inability to eat, and a pulse that was deep, fine, wiry, and rapid. The physician stated: This is accumulation of retained fluid (water-dampness retention due to impaired metabolism). The treatment principle should be to purge the accumulated fluid, after which the disease can be eliminated. However, since the illness has persisted for a long time and the patient is frail, aggressive purging must not be excessive. A prescription was used to harmonize the middle jiao (middle burner) and eliminate dampness. After taking the medicine, severe lower abdominal pain occurred accompanied by fainting, followed by vomiting a basin full of liquid, all of which was green water. The crowd was astonished and asked: Why did this happen? The physician replied: I originally suspected dampness. Just as moss grows on damp ground, the principle is the same; once the root cause is identified, there is no great harm. (Ibid.)
Luo Lian, nearing his prime years, suffered from pain in the epigastrium radiating to the back, hypochondrium, and heart region, with vomiting of clear fluid. Over time, the pain intensified, feeling like knife cuts, and he became mentally confused and dazed. His family physicians exhausted their skills, claiming the six pulses had ceased. When Wei Zhiqiu arrived, he said: This is retained fluid. The pain is so severe that the pulse is hidden (deep and imperceptible), not actually absent. He then administered warming and tonifying decoctions. After one dose, the pulse reappeared; after two doses, the patient recovered. (*Taihan Ji*.)
Xu Lingtai commented: All diseases involve pathogenic factors. For instance, if a person drinks herbal decoction but vomits it all up shortly after, it is because there is cold-fluid retention in the stomach, causing rejection of ingested food. The treatment principle should be to support yang qi, purge fluid retention, dispel cold pathogens, and only then tonify middle qi. It is essential to include herbs that purge fluid retention; one cannot merely use Ren Shen (Ginseng Root) and Bai Zhu (Atractylodes Macrocephala Rhizome) to tonify and inadvertently trap the cold-fluid. If there are no pathogenic factors yet symptoms present such severity, it is a sign of stomach qi exhaustion, and treatment is unnecessary. A man surnamed Jin from Dongting Lake suffered from vomiting. His ancestors were close friends with Ye Tianshi. Ye Tianshi treated him diligently for over a year, during which the patient nearly died, so they sought treatment from...
