泄痢之人，若不禁生冷鱼肉肥腻，与不服药同。（《幼幼》引《养生必用》）（《六要》曰∶若宿滞未净，
又增新者，肠胃何由以清。渐渐壅塞，直至恶心不食，成噤口矣。）
一男子病脓血恶痢，痛不可忍，忽见水浸甜瓜，心酷喜之，连皮食数枚，脓血皆已。人言下痢无正形，是何
言也。人止知痢是虚冷，温之燥之涩之截之，此外无术矣；岂知风暑火湿燥寒六者皆为痢，此冰蜜甜瓜所以效
也。（《杂记九门》）（按∶又载病泄食羊肝而愈，且曰∶戴人常曰∶胃为
水谷之海，不可虚怯，虚怯则百邪皆入矣。或思荤茹，虽与病相反，亦令少食，图引浆粥，此权变之道也。若
专以淡粥责之，则病患不悦而食减，久则病增损命，世俗误人矣。）
下利以胃气为本，胃失生长，故恶物而不欲食。但得思食，无分何物，与之遂获愈者，此胃气胜故也。
（《医通》）（按∶此说本于戴人。）
治一妇患痢疾，素瘦弱，久卧病，而粥入胃，即腹痛且呕吐，必吐尽所食乃止。由是粒食不下咽，四十余
日，众医为危，特迎予诊。曰∶病与脉应，无虑也。不劳以药，惟宜饲以米饮，使胃常得谷气，白露节后，症当
获安。如期果愈。（《石山医按》）
痢后风（详载于《历节》中）
痢后脱肛（治方详出《脱肛》中）脱肛者，肛门脱出也，多因久痢后大肠虚冷所为。肛门为大肠之候，
大肠虚而伤于寒，痢而用气KT ，其气下冲，则肛门脱出，因谓脱肛也。（《病源论》）
下痢脱肛，以养脏汤加升麻，去木香主之。（《原病集》）
患有泄泻痢疾的人，如果不禁忌生冷、鱼肉及肥腻食物，这与不服药的效果是一样的。（《幼幼新书》引用《养生必用》）（《六要》说：如果宿存的积滞尚未清除，又增加了新的饮食，肠胃怎么能保持清净？逐渐地壅塞不通，直到出现恶心不想吃东西，形成噤口痢。）
有一个男子患脓血恶痢，疼痛难以忍受，忽然看见浸泡在水中的甜瓜，心里非常喜爱，连皮吃了几枚，脓血症状随即消失。人们说下痢没有固定的形态，这是什么话呢？人们只知道痢疾是虚寒证，采用温补、燥湿、收敛、截断的方法，除此之外别无他法；哪里知道风、暑、火、湿、燥、寒这六种邪气都能导致痢疾，这就是冰蜜和甜瓜之所以有效的缘故。（《杂记九门》）（按语：又记载有人因食用羊肝而治愈泄泻病，并且说：戴人常讲：胃是水谷之海，不能虚弱怯弱，虚弱则各种邪气都会侵入。如果病人想吃荤腥，虽然与病情相反，也应让他少量食用，以图引导喝进米汤粥水，这是权宜变通之道。如果一味要求吃清淡的白粥，病人会不高兴且进食减少，时间久了病情加重损害生命，这是世俗医生误导人的地方。）
下利以胃气为根本，胃气失去生化之源，所以厌恶秽物而不想进食。只要病人产生食欲，不分是什么食物，给予后就能痊愈，这是因为胃气旺盛的缘故。（《医宗必读》）（按语：这种说法源于戴人。）
治疗一位患痢疾的妇女，平时身体瘦弱，长期卧床患病，但粥进入胃里，就腹痛并呕吐，必须把吃的东西全部吐完才停止。因此颗粒食物无法咽下，四十多天，众医认为病情危重，特意请我诊治。我说：病症与脉象相应，不用担心。不用劳神用药，只适宜喂米汤，使胃经常得到谷气滋养，白露节气过后，症状应当获得安宁。到期果然痊愈。（《石山医案》）
痢后风（详细记载于《历节》篇中）
痢后脱肛（治疗方剂详细见《脱肛》篇）脱肛，是指肛门脱出体外，多因为久痢之后大肠虚冷所致。肛门是大肠的外候，大肠虚弱且受寒邪损伤，痢疾时用力排便，气机下冲，导致肛门脱出，因此称为脱肛。（《诸病源候论》）
Patients with diarrhea and dysentery, if they do not abstain from raw/cold foods, fish/meat, and fatty/greasy items, are equivalent to taking no medicine. (Cited in *Youyou Xinshu* from *Yangsheng Biyong*) (*Liuyao* states: If old stagnation is not cleared, and new food is added, how can the intestines and stomach remain clear? Gradually, blockage occurs, leading to nausea and loss of appetite, resulting in Jin Kou Li (Jin Kou Dysentery).)
A man suffered from severe purulent and bloody dysentery with unbearable pain. He suddenly saw melons soaked in water and felt a strong desire for them. He ate several whole, including the skin, and the purulent and bloody symptoms ceased. People say that dysentery has no fixed form; what kind of statement is this? People only know that dysentery is a deficiency-cold syndrome, treating it with warming, drying, astringing, and blocking methods, believing there are no other techniques; how could they know that wind, summerheat, fire, dampness, dryness, and cold as six pathogenic factors can all cause dysentery? This explains why ice-sweetened melon is effective. (*Zaji Jiumen*) (Note: It also records a case where eating sheep liver cured diarrhea, stating: Dai Ren often said: The Stomach is the sea of water and grain; it must not be deficient or weak. If deficient, all evils will enter. If one craves meat, even if contrary to the disease, allowing small amounts can help induce the intake of broth or gruel. This is a method of flexible adaptation. If one strictly demands bland gruel, the patient becomes displeased and eats less; over time, the disease worsens, damaging life. This is how worldly doctors mislead people.)
Lowering discharge (Xia Li) relies on Stomach Qi as its root. When Stomach Qi loses its ability to generate and nourish, the body rejects foul matter and lacks appetite. However, if the patient desires food, regardless of what it is, and recovery follows upon consumption, this is because Stomach Qi is strong. (*Yitong*) (Note: This theory originates from Dai Ren.)
Treated a woman suffering from dysentery. She was naturally thin and weak, and had been bedridden for a long time. Whenever porridge entered her stomach, she experienced abdominal pain and vomiting, stopping only after expelling all ingested food. Consequently, she could not swallow any solid food for over forty days. Many physicians deemed her condition critical and invited me to consult. I said: The symptoms correspond with the pulse; there is no need to worry. Do not burden the body with medication. It is best to feed her rice water, so that the Stomach constantly receives the qi of grains. After the White Dew solar term, her symptoms should resolve. As predicted, she recovered on schedule. (*Shishan Yi An*)
Post-dysentery Wind (Detailed in the *Li Jie* chapter)
Post-dysentery Rectal Prolapse (Treatment formulas detailed in the *Tuo Gang* chapter). Rectal prolapse refers to the protrusion of the anus. It is mostly caused by deficiency and cold of the Large Intestine following chronic dysentery. The anus is the external manifestation of the Large Intestine. When the Large Intestine is deficient and injured by cold, and during dysentery, straining causes Qi to rush downward, the anus protrudes, hence the name "Rectal Prolapse" (*Tuo Gang*). (*Bing Yuan Lun*)
For lower dysentery accompanied by rectal prolapse, treat primarily with Yang Zang Tang (Nourish Viscera Decoction) adding Sheng Ma (Cimicifugae Rhizoma), and removing Mu Xiang (Aucklandiae Radix). (*Yuan Bing Ji*)
