藿香正气散：治疗风邪损伤胃腑，导致阴阳失调，出现上吐下泻的症状。
紫苏叶（一钱） 大腹皮（一丸） 芽桔梗（一钱） 白云苓（一钱） 制半夏（一钱五分） 川浓朴（一钱）
真广皮（一钱） 炙甘草（一钱）
生姜三片，大枣三枚，加水煎煮，热服。
六君子汤：方剂见卷二“非搐门”。
理中汤：方剂见卷二“乳子伤寒门”。此方加入藿香、木瓜。
五苓散：方剂见卷二“中暑门”。加入藿香。
盐汤催吐法：其方法是用温水调配略咸的食盐，一大碗，让患儿服用。过一段时间后，用手指探入喉间催吐，一旦吐出症状即缓解。
凡是霍乱伴有呕吐、腹泻、腹痛的患者，切忌饮用热汤及米汤，若违反必死无疑；必须等待其呕吐腹泻停止一两个时辰后，服药过后，等到其胃气稍恢复，口渴止住且知道饥饿时，才可以给予稀粥食用。
凡是霍乱呕吐严重，无法受纳药物和食物的危重患者，迅速用新汲水和百沸汤（滚开水）各一盏混合均匀，名为阴阳汤，饮用数日即可安定。
凡是痰疟及宿食恶毒之物，阻塞中焦，导致腹胀欲发霍乱者，立即给予盐汤，令其一次性服下，吐尽痰食即可安宁。
霍乱吐泻诸药无效时，取绿豆、胡椒各二十一粒，研细，水煎服；如果口渴严重者，将这两味药研细，用新汲井水调服则安。
另一方用六一散一二钱，用浓姜汤调服，夏季使用更佳。因为六一散性凉，姜汤性热，这也是“寒因热用”的意思。
干霍乱即绞肠痧，其症状忽然心腹绞痛难以忍受，上不能吐，下不能泻，痰壅腹胀，手足厥冷，六脉沉细或伏匿，死亡只在顷刻之间，真是凶险的证候。紧急时用食盐一两，生姜五钱，捣碎，同盐炒至黑色，用水一大碗，煎煮数沸，温服。过一段时间后，用手指探喉催吐，或者不吐即泻。
绞肠痧也有阴阳之分。阴痧腹痛手足冷，看身上有红点，用灯火在红点上淬烫；阳痧腹痛手足暖，用针刺其十指背近指甲处约韭菜叶宽的地方，出血即安，仍先从两臂捩下恶血，使其聚集于指头，然后刺之。
凡是发痧出现手足厥冷、腹痛，用温水一碗，令病患俯卧在凳子上，用手蘸水拍打其两膝弯处，名为委中穴，看到有紫黑点显现，用针刺出恶血即愈（脾脉、肝脉、肾脉、三阴之脉都经过此委中穴。）又一种方法，用香油拍打两手曲池穴，即肘内弯处，用浸了油的麻束刮擦，刮起紫疹，立刻即愈。（肺脉、心脉、心包络脉都从此曲池穴经过。以上做法，也是疏散邪气的意思。）
Huoxiang Zhengqi San (Patchouli and Magnolia Bark Powder): Treats wind pathogen injuring the Stomach, leading to disharmony of Yin and Yang, with symptoms of vomiting above and diarrhea below.
Perilla Leaf (Qian), Areca Peel (Wan), Bud Platycodon Root (Qian), White Poria (Qian), Processed Pinellia Tuber (Qian 5 Fen), Sichuan Magnolia Bark (Qian), True Tangerine Peel (Qian), Honey-fried Licorice Root (Qian).
Add three slices of Fresh Ginger and three Jujubes, decoct in water, and take warm.
Liujunzi Tang (Six Gentlemen Decoction): Formula seen in Volume II, Chapter "Non-Convulsive Disorders".
Lizhong Tang (Regulate the Middle Decoction): Formula seen in Volume II, Chapter "Infant Cold Damage". This formula adds Patchouli and Quince.
Wuling San (Five-Ingredient Powder with Poria): Formula seen in Volume II, Chapter "Heatstroke". Adds Patchouli.
Salt Water Emetic Method: The method involves mixing table salt with warm water until slightly salty, one large bowl, for the child to drink. After a while, probe the throat with a finger to induce vomiting; once vomited, relief follows immediately.
In cases of Huoluan (Acute Vomiting and Diarrhea) with vomiting, diarrhea, and abdominal pain, hot soups and rice gruel are strictly contraindicated; violating this leads to death. One must wait one or two hours after vomiting and diarrhea cease, and after administering medicine, until the Stomach Qi recovers slightly, thirst stops, and hunger is felt, before offering thin rice gruel.
For severe Huoluan where vomiting prevents the intake of medicine and food, quickly mix one cup of fresh well water with one cup of boiling water, named Yinyang Tang (Yin-Yang Decoction). Drinking this for several days will stabilize the condition.
When phlegm-malaria or retained food and toxic substances block the Middle Jiao, causing abdominal distension and impending Huoluan, administer salt water immediately for single-dose ingestion. Vomiting out the phlegm and food brings relief.
If various medicines fail for Huoluan vomiting and diarrhea, grind twenty-one mung beans and twenty-one peppercorns finely, decoct in water, and take. If thirst is severe, grind these two ingredients finely and take mixed with fresh well water for relief.
Another prescription uses Liuyi San (Six-to-One Powder) 1-2 Qian, taken with strong ginger soup, which is particularly effective in summer. Since Liuyi San is cooling and ginger soup is hot, this follows the principle of "treating cold with heat" (Han yin re yong).
Gan Huoluan (Dry Huoluan), also known as Jiaochang Sha (Intestinal Cramping Sha), presents with sudden unbearable heart and abdominal colic, inability to vomit above or defecate below, phlegm obstruction and abdominal distension, cold limbs, and deep, fine, or imperceptible pulses. Death occurs within moments; it is truly a malignant syndrome. Urgently use one liang of table salt and five qian of fresh ginger, crush them, stir-fry with salt until black, decoct in one large bowl of water for a few boils, and take warm. After a while, probe the throat to induce vomiting, or it may result in diarrhea instead.
Jiaochang Sha also has Yin and Yang types. Yin Sha features abdominal pain and cold limbs; look for red spots on the body and cauterize them with a lamp flame. Yang Sha features abdominal pain and warm limbs; prick the dorsal side of the ten fingers near the nail beds, about the width of a leek leaf, to bleed, bringing immediate relief. First, twist the arms to draw bad blood to the fingertips, then prick.
For Sha syndromes presenting with cold limbs and abdominal pain, use one bowl of warm water. Have the patient lie prone on a stool. Dip hands in water and slap the popliteal fossae bilaterally, known as Weizhong BL40. When purple-black spots appear, prick them with a needle to release bad blood for cure (The Spleen, Liver, Kidney, and all Three Yin meridians pass through Weizhong BL40.) Another method: apply sesame oil to the Quichi LI11 acupoints (the elbow creases), dip hemp fibers in the oil, and scrape the skin until purple rashes appear, resulting in immediate cure. (The Lung, Heart, and Pericardium meridians pass through Quichi LI11. These methods aim at dispersing and diffusing pathogens.)
