附可驱寒。热多而渴五苓散，暑证香薷藿朴堪。
【论】夫霍乱者，挥霍撩乱也。外有所感，内有所伤，阴阳乖隔，上吐下利，躁扰闷痛是也。偏阳则多
热，偏阴则多寒。卒然而成，危如风烛，得吐利者，名曰湿霍乱，为可治，盖所伤之物尽出故也。若上不得吐，
下不得利，所伤之物不得出，壅闷正气，关格阴阳，其死甚速，须用盐汤探吐，得出则宽。轻者手足温和，甚
者脐腹绞痛，厥逆脉脱，举体转筋，当温补回阳复脉。若暑月多食瓜果、泉水，以致食郁于中而成霍乱者，宜
辛温散其标寒，次以寒凉清其暑热可也。渴甚者，冰水解之。

[Song] Huoluan (Acute Vomiting and Diarrhea) must be distinguished into damp type and dry type; peace can only be restored after vomiting and diarrhea have expelled the pathogenic factors. If Guan-Ge (obstruction of upper and lower orifices) occurs with reversal of Yin and Yang, life and death are decided in an instant. In severe cases, muscle cramps (Zhuanjin) and even cold extremities occur; Lizhong Tang (Regulate the Middle Decoction) with Ginger and Aconite can dispel cold. If heat is prominent with thirst, Wuling San (Five-Ingredient Poria Powder) should be used; for summerheat patterns, Moslae Herba (Xiangru), Pogostemonis Patchouli Herba (Huoxiang), and Magnoliae Officinalis Cortex (Houpo) are suitable.
[Discussion] Huoluan refers to a state of chaotic turmoil upon onset. External pathogens combined with internal dietary injury cause a disruption of Yin and Yang, manifesting as vomiting above and diarrhea below, accompanied by restlessness, stifling sensation, and pain. Predominance of Yang leads to more heat, while predominance of Yin leads to more cold. The disease strikes suddenly, as precarious as a candle in the wind. Cases presenting with vomiting and diarrhea are named Damp Huoluan (Wet Huoluan); they are treatable because the ingested harmful substances are expelled. If one cannot vomit above nor defecate below, the harmful substances remain trapped, obstructing healthy Qi and causing Guan-Ge with reversal of Yin and Yang, leading to rapid death. In such cases, salt water should be used to induce vomiting; relief follows once the obstruction is cleared. Mild cases present with warm hands and feet; severe cases involve colicky abdominal pain, cold extremities, faint pulse, generalized muscle cramps, and require warming, tonifying, restoring Yang, and reviving the pulse. If Huoluan results from excessive consumption of melons, fruits, or spring water during summer, causing food stagnation in the middle Jiao, it is appropriate to first use acrid-warm herbs to disperse exterior cold, followed by cool-cold herbs to clear summerheat. For severe thirst, ice water may be used to resolve it.
[Pulse Diagnosis] Pulses in Huoluan with vomiting and diarrhea are slippery but irregular. They may be fine and choppy, or deep and hidden, which is alarming. Prominent heat presents with surging and slippery pulses; wiry and slippery pulses indicate food retention.
Damp Huoluan (i.e., Huoluan with vomiting and diarrhea)
For Huoluan with vomiting and diarrhea, Huoxiang Zhengqi San (Patchouli Powder to Rectify the Qi) is indicated. For abdominal pain, cold extremities, and deep pulse, Lizhong Tang (Regulate the Middle Decoction) is used. For persistent muscle cramps, Mugua San (Papaya Powder) is used; prick purple blood from red veins inside the knees and wrists; apply hot fried salt to the umbilicus.
Huoxiang Zhengqi San
Indicated for maladaptation to climate, intolerance to local conditions, spleen-stomach disharmony, vomiting, diarrhea, abdominal pain, food stagnation, nausea, and chest fullness.
Ingredients: Pogostemonis Patchouli Herba (Huoxiang, 2 qian), Angelicae Dahuricae Radix (Baizhi, 1 qian), Platycodonis Radix (Jiegeng, 1 qian), Pinelliae Rhizoma Preparatum (Banxia, 1 qian, prepared with ginger), Perillae Folium (Zisu, 1 qian), Citri Reticulatae Pericarpium (Chenpi, 1 qian), Atractylodis Macrocephalae Rhizoma (Baizhu, 1 qian, stir-fried), Arecae Pericarpium (Dafupi, 1 qian), Poria (Fuling, 1 qian), Magnoliae Officinalis Cortex (Nongpo/Houpo, 1 qian, stir-fried with ginger), Glycyrrhizae Radix et Rhizoma (Gancao, 0.5 qian, honey-fried).
Crush the herbs. For one dose, add three slices of ginger and two jujubes, decoct in water, and take warm.
Modifications: Add Papaya (Mugua) for muscle cramps. Add stir-fried Peony Root (Shaoyao) for abdominal pain; add Cinnamon Twig (Guizhi) for cold pain. Add Cyperi Rhizoma (Xiangfu), Amomi Fructus (Sharen), Medicated Leaven (Shenqu), and Hordeum Vulgare Germinatum (Maiya) for indigestion.

Combine with Wuling San if urination is difficult. Add Aurantii Fructus Immaturus (Zhike) if there is frequent urge to defecate without passage.
Lizhong Tang (See "Cold Damage to the Middle" chapter for formula)
Mugua San
Ingredients: Papaya (Mugua, 2 qian), Fennel Fruit (Huixiang, 0.35 qian), Glycyrrhizae Radix et Rhizoma (Gancao, 0.2 qian, honey-fried), Evodiae Fructus (Wuzhuyu, 1.5 qian), Perillae Folium (Zisu, 10 leaves), Zingiberis Rhizoma Recens (Shengjiang, 5 slices).
Crush the herbs. For one dose, add two cups of water, decoct until reduced to 0.8 cup, and take warm on an empty stomach.
Dry Huoluan (Colic Sha, colloquially known as Intestinal Twisting Sha)
Inability to vomit or defecate, severe umbilical and abdominal pain, extreme restlessness and stifling pain.灌 down about one bowl of salt water to induce vomiting. If vomiting does not occur, the condition is untreatable. Additionally, stir-fry 3-4 liang of Evodiae Fructus (Wuzhuyu) with several liang of salt until hot, and apply as a compress to the area below the umbilicus.
Summerheat Huoluan
For summer Huoluan, Liuhe Tang (Six-Harmonies Decoction) is used. For heat with dryness, thirst, and restlessness, use Wuling San, or mix Yiyuan San (Benefit Primordial Powder) with cool water, or Gui Ling Gan Lu Yin (Cassia, Poria, and Sweet Dew Drink), or Huo Ru Tang (Patchouli and Mosla Decoction) taken cold.
Liuhe Tang
Indicated for summerheat invasion, latent heat causing restlessness, dysfunction of Qi ascending and descending, Huoluan with muscle cramps, vomiting and diarrhea, alternating chills and fever, phlegm and wheezing, chest diaphragm stuffiness, dizziness and headache, limb edema, dark and scanty urination, lethargy and desire to sleep, as well as post-alcohol thirst and aversion to food. Modify according to symptoms.
Ingredients: Amomi Fructus (Suosha, 1 liang), Pinelliae Rhizoma (Banxia, 1 liang), Prunus Armeniaca Semen (Xingren, 1 liang), Dolichos Lablab Seed (Baidou, 2 liang), Ginseng Radix et Rhizoma (Renshen, 1 liang), Glycyrrhizae Radix et Rhizoma (Gancao, 1 liang, honey-fried), Red Poria (Chifuling, 2 liang), Pogostemonis Patchouli Folium (Huoxiangye, 2 liang), Papaya (Mugua, 2 liang), Moslae Herba (Xiangru, 4 liang), Magnoliae Officinalis Cortex (Nongpo/Houpo, 4 liang, stir-fried with ginger).
Crush the herbs. Take 1 liang per dose, decoct with ginger and jujube in water.
Commentary: "Liuhe" means harmonizing the Six Fu Organs. The Spleen and Stomach are the masters of the Six Fu Organs; thus, for diseases of disharmony in the Six Fu Organs, treatment begins by regulating the Spleen and Stomach. This formula contains Huoxiang and Sharen; their fragrance opens the stomach orifice. Banxia and Shengjiang are acrid and disperse rebellious Qi. Fuling and Mugua are bland and drain dampness. Renshen, Baizhu, and Bian Dou are sweet and regulate the Spleen and Stomach. Once the Spleen and Stomach are regulated, fluids distribute evenly, and the Five Meridians function together, bringing harmony to the limbs, bones, and orifices, let alone the Six Fu Organs.
Wuling San (See "Dampness" chapter for formula)
Yiyuan San, also known as Liuyi San
Ingredients: Talcum (Huashi, 6 liang, water-ground), Glycyrrhizae Radix et Rhizoma (Gancao, 1 liang).
Grind into fine powder, mix with water, and take.
Gui Ling Gan Lu Yin
Indicated for excessive drinking in summer, abdominal distension, Huoluan with diarrhea, dark and scanty urination, dry mouth, and thirst.
Ingredients: Atractylodis Macrocephalae Rhizoma (Baizhu, 2 liang, stir-fried), Poria (Baifuling, 2 liang), Polyporus (Zhuling, 2 liang), Alismatis Rhizoma (Zexie, 2 liang, dehusked), Talcum (Huashi, ground, 2 liang), Halloysit Rubra (Hanshuishi, ground, 1 liang), Glycyrrhizae Radix et Rhizoma (Gancao, 1 liang, honey-fried), Cinnamomi Cortex (Rougui, peeled, 5 qian).
Crush the herbs. Take 1.5 liang per dose, decoct in two zhong of water until reduced to 0.8, and take warm.
Commentary: The above formula uses Wuling San to drain dampness from the Triple Burner. The two stones (Talcum and Halloysit) clear heat from the Six Fu Organs. This is a simple method for treating damp-heat advocated by He Jian. Zhang Zihe added Ginseng because the patient's pulse was deficient.
