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》）
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*)
