便黄因内热，红赤黑同看。绿白青皆冷，积滞气臭酸(37)。
久泻四肢瘫，才惊睡不安。热疳毛作穗，涎嗽定伤寒。
肝冷传脾臭绿青，焦黄脾土热之形。肺肠寒色脓粘白，赤热
因心肾热成。
身热发厥歌(久泄多虚热)
气虚多发厥，血虚须作热。气血若俱虚，身热手足厥。
吐泻名曰霍乱，其症有三：有寒、有热，有食积。
凡上吐下泻，两腮红赤，遍身热，口作渴，吐泄时多而出物
少者，此属于热。用五苓散煨干姜治之，或用煨姜汤澄冷调服益
元散，神效。
凡上吐下泻，面胱白，足冷。腹痛，多啼哭，不作渴，吐泻
时少而出物多者，此属于寒，用理中汤治之。甚者，加附子乌梅
效。以上二症，皆不阻乳食。
凡吐泻出物酸臭，面黄，不喜饮食，腹常作痛者，此食积
也。以丁香脾积丸推去其积，后以集圣丸调之。
凡吐泻久，身瘦作热者，只用集圣丸治之。
祖传治吐泻，不问寒热虚实，只用胃苓丸，煨姜汤送下，即
安。
益元散(又名六一散，又名天水散)
滑石六两，甘草一两，为细未，或煎服，或冷水调
服。
凡吐泻不止，作渴不休者，不治。加惊搐者，不治。口舌生
疮，手足冷，身热，此阴降阳升。脾气中绝者，不治。
西江 月
大凡男女吐泻，阴阳顺逆当明，男逢泻甚下无阴，女子吐多
不应。出物多而数少，此为寒盛相侵。如逢物少数频频，火盛细加
体认。
吐泻若是同见，此名霍乱阴阳，只用一剂理中汤，上吐下泻
了当。服此若还不效，再加热附煨姜，乌梅作引是良方，莫与俗人
夸奖。
吐泻时时作渴，诸般汤药无灵，饮汤饮水腹膨膨，束手坐观
死症。急用伏龙饮子，时时与吃调停;须臾吐止火邪宁，才与理
中对症。
吐泻分为三症，食积、寒、热当知，面黄粪臭恶乳食，此症
方为食积。若是身热作渴。宜为热症袪除，面白身寒腹痛时，正
是虚寒之疾。
食积宜行转取，灵应去积为宜，如逢热症又何如，益元五苓
为主。寒症理中可用，甚加附子乌梅，寒热总用胃苓奇，吞用干姜
煎水。
Stool yellow is due to internal heat; red, crimson, and black are viewed similarly. Green, white, and cyan all indicate cold patterns; if accompanied by food stagnation, the odor is sour (37).
Prolonged diarrhea leads to flaccidity of the four limbs; sudden fright or restless sleep indicates instability. Heat-related malnutrition (Re Gan) presents with hair clumping like tufts; phlegm-cough suggests Taiyang Cold Damage (Shanghan).
Liver cold transmitting to the Spleen causes green/cyan stool with a foul odor; scorched yellow is the manifestation of Spleen Earth heat. Lung and Intestine cold present with sticky, white pus; redness and heat result from Heart and Kidney heat.
Song on Body Heat and Cold Extremities (Prolonged diarrhea often involves deficiency-heat)
Qi deficiency frequently induces cold extremities (Jue); Blood deficiency must manifest as heat. If both Qi and Blood are deficient, the body feels hot while the hands and feet are cold.
Vomiting and diarrhea combined are called Huoluan (Cholera-like syndrome), presenting in three types: Cold, Heat, and Food Stagnation.
When there is vomiting and diarrhea, reddish cheeks, generalized fever, thirst, frequent episodes with scanty discharge, this belongs to Heat. Treat with Wuling San (Five-Ingredient Powder with Poria) plus calcined Ginger, or administer Yi Yuan San (Benefit Prime Powder) cooled in calcined Ginger Decoction; the effect is miraculous.
When there is vomiting and diarrhea, pale complexion, cold feet, abdominal pain, frequent crying, no thirst, infrequent episodes with abundant discharge, this belongs to Cold. Treat with Lizhong Tang (Regulate the Middle Decoction). For severe cases, adding Fuzi (Aconite Lateral Root) and Wumei (Mume Fruit) is effective. In these two conditions, breast milk and food intake are not obstructed.
When vomit and stool are sour and foul-smelling, the face is yellow, appetite is poor, and the abdomen is often painful, this is Food Stagnation. Use Dingxiang Pi Ji Wan (Clove Spleen Accumulation Pill) to expel the stagnation, followed by Jisheng Wan (Accumulated Sage Pill) for regulation.
For prolonged vomiting and diarrhea with emaciation and heat, use only Jisheng Wan.
Ancestral treatment for vomiting and diarrhea, regardless of Cold, Heat, Deficiency, or Excess, uses Weiling Wan (Stomach Regulating Pill) delivered with calcined Ginger Decoction, bringing immediate relief.
Yi Yuan San (Also known as Liuyi San / Six-to-One Powder, also known as Tianshui San)
Huaishi (Talcum) six liang, Gancao (Licorice Root) one liang, ground into fine powder. Can be decocted and taken, or mixed with cold water.
If vomiting and diarrhea do not cease and thirst persists, it is incurable. If accompanied by convulsions, it is incurable. Mouth and tongue ulcers, cold hands and feet, and body heat indicate Yin descending and Yang ascending, with the interruption of Spleen Qi; it is incurable.
Xijiang Yue (Poem)
Generally, for male or female vomiting and diarrhea, one must understand the smoothness or reversal of Yin and Yang. In men, severe diarrhea depletes Yin below; in women, excessive vomiting is abnormal. Abundant discharge but infrequent frequency indicates severe Cold invasion. Infrequent discharge but frequent frequency requires careful assessment for Fire Excess.
When vomiting and diarrhea occur together, it is named Huoluan involving Yin-Yang imbalance. One dose of Lizhong Tang can resolve upper vomiting and lower diarrhea. If this is ineffective, add Fuzi and calcined Ginger, using Wumei as a guide; this is a good prescription, do not boast to laymen.
If vomiting and diarrhea cause constant thirst, and various decoctions fail, drinking fluids leads to abdominal distension, facing death helplessly. Urgently use Fulong Yinzi (Dragon's Kiln Mud Drink), administered intermittently; once vomiting stops and Fire Evil calms, then treat appropriately with Lizhong Tang.
Vomiting and diarrhea are divided into three syndromes: Food Stagnation, Cold, and Heat. Yellow face, foul feces, and aversion to milk/food indicate Food Stagnation. If body heat and thirst are present, it should be treated as Heat Syndrome. Pale face, cold body, and abdominal pain indicate Deficient-Cold disease.
Food Stagnation requires moving Qi and resolving accumulation; Lingying Quji Wan is suitable. For Heat Syndrome, Yi Yuan San and Wuling San are primary. For Cold Syndrome, Lizhong Tang is usable, adding Fuzi and Wumei for severe cases. For both Cold and Heat, Weiling Wan is unique, taken with dry ginger decoction.
