熟读在胸，救人无算。与时医所论阴阳，迥不相同。
折三剂，每味三钱。
人参 甘草（炙） 白术 干姜（各三两） 上四味，
捣筛为末，蜜和为丸，如鸡子黄许大。以沸汤数合，和一丸研碎，温服之，日三、四服，夜二服。腹中未
热，益至三、四丸，然不及汤。理中丸与汤本属一方。汤法以四物根据两数切，用水八升，煮取三升，去
渣，温服一升，日三服。急则用汤。若脐上筑者，肾气动也，去术加桂四两；即欲作奔豚，桂枝加桂之法。
吐多者，去术加生姜三两；有干姜而复加生姜，知干姜不治呕也。下多者，还用术；术能止利。悸者，
加茯苓二两；悸为心下有水，故用茯苓。渴欲饮水者，加术，足前成四两半；消饮生津。腹中痛者，加
人参，足前成四两半；此痛因气不足之故。《别录》云∶人参治心腹鼓痛。寒者，加干姜，足前成四两半；腹
满者去术，加附子一枚，此腹满乃阳气不充之故。服汤后，如食顷，饮热粥一升许，微自温，勿揭衣被。
桂枝汤之饮热粥，欲其助药力以外散；此饮热粥，欲其助药力以内温。
霍乱头痛发热，身疼痛，《论》中又云∶呕吐而利，名曰霍乱。又云∶头痛则身疼，恶寒吐利，名曰
霍乱。合观之，则霍乱之症始备，盖亦伤寒之类。后人以暑月之吐利当之，而亦用理中，更造为大顺散者，
皆无稽之论也。热多欲饮水者，五苓散主之；此热胜寒之霍乱。寒多不用水者，理中汤主之。此寒胜热
之霍乱。
按∶霍乱之症，皆由寒热之气不和，阴阳拒格，上下不通，水火不济之所致。五苓所以分其清浊；理
中所以壮其阳气，皆中焦之治法也。
大病瘥后，喜唾，胃液不藏，兼有寒饮，久不了了，胃上有寒，当以丸药理之，当缓治之。宜理中丸。
（此书）熟记于心，救人无数。与时下医生所论述的阴阳理论，截然不同。
将上述药物各折半使用，每味药三钱。
人参、甘草（炙）、白术、干姜（各三两）。以上四味药，
捣碎并筛成细末，用蜂蜜调和制成丸剂，大小如鸡蛋黄。用沸水少量，将一丸研碎后调匀，温服，每日三至四次，夜间两次服用。若腹中未感到温热，可增加至三至四丸，然而效果不如汤剂。理中丸与理中汤本属同一方剂。汤剂的煎法是将四味药根据原剂量切制，用水八升，煮取三升，去渣，温服一升，每日三次服用。病情紧急时使用汤剂。如果脐上跳动不安，是肾气发动之象，去掉白术，加入桂枝四两；这就是欲发奔豚病时，使用桂枝加桂汤的方法。呕吐较多者，去掉白术，加入生姜三两；既然已有干姜却还要再加生姜，可知干姜并不能治疗呕吐。腹泻较多者，仍需用白术；因为白术能止泻。心悸者，加入茯苓二两；心悸是因为心下有停饮，所以用茯苓。口渴想喝水者，增加白术用量，使总量达到四两半；以消除饮邪并生津液。腹中疼痛者，增加人参用量，使总量达到四两半；这种疼痛是由于气虚所致。《本草别录》记载：人参能治疗心腹部胀满疼痛。身体寒冷者，增加干姜用量，使总量达到四两半；腹部胀满者去掉白术，加入附子一枚，这种腹满是因阳气不足所致。服药后，约一顿饭的时间，喝热粥一升左右，使身体微微温暖，不要揭开衣被。服用桂枝汤后喝热粥，是为了帮助药力向外发散；此处喝热粥，是为了帮助药力向内温补。
霍乱症见头痛、发热、身体疼痛，《伤寒论》中又说：呕吐且腹泻，称为霍乱。又说：头痛则身痛，恶寒伴吐利，称为霍乱。综合来看，霍乱的病症才完备，这大概也是伤寒的一类。后人将暑月发生的吐利当作霍乱，也使用理中汤，甚至创制大顺散，这些都是没有根据的言论。热重想喝水者，主用五苓散；这是热胜寒的霍乱。寒重不想喝水者，主用理中汤；这是寒胜热的霍乱。
按语：霍乱的病症，都是由寒热之气不和，阴阳相互格拒，上下不通，水火不济所导致。五苓散的作用是分清浊；理中汤的作用是壮阳气，这都是针对中焦的治疗方法。
大病初愈后，喜欢流口水，这是胃液不能固藏，兼有寒饮，久久不好，属于胃上有寒，应当用丸药调理，宜缓治。适宜使用理中丸。
(With this book) firmly memorized, one can save countless lives. It differs significantly from the theories of Yin and Yang discussed by contemporary physicians.
Halve the dosage, using three qian of each ingredient.
Renshen (Ginseng Root), Gancao (Licorice Root, honey-fried), Baizhu (Atractylodes Rhizome), Ganjiang (Dried Ginger) (each 3 liang). The above four ingredients,
are crushed, sifted into powder, mixed with honey to form pills, sized like a chicken egg yolk. Take one pill, crush it, and mix it with a small amount of boiling water; take warm, three to four times daily, and twice at night. If warmth is not felt in the abdomen, increase to three or four pills; however, the decoction is more effective. Lizhong Wan (Regulate the Middle Pill) and Lizhong Tang (Regulate the Middle Decoction) originally belong to the same formula. For the decoction method, cut the four ingredients according to the original dosage, add eight sheng of water, boil to obtain three sheng, remove the dregs, and take one sheng warm, three times daily. Use the decoction for urgent conditions. If there is a sensation of beating above the navel, it indicates movement of Kidney Qi; remove Baizhu and add Guizhi (Cinnamon Twig) four liang; this is the method of adding Gui Zhi Jia Gui Tang (Cinnamon Twig Decoction with Additional Cinnamon Twig) when Ben Tun (Running Piglet Syndrome) is about to occur. If vomiting is frequent, remove Baizhu and add Shengjiang (Fresh Ginger) three liang; since Ganjiang is already present but Shengjiang is added again, it indicates that Ganjiang does not treat vomiting. If diarrhea is frequent, continue to use Baizhu; as Baizhu can stop dysentery/diarrhea. If there is palpitations, add Fuling (Poria) two liang; palpitations are caused by fluid retention below the heart, hence Fuling is used. If thirsty and desiring to drink water, increase Baizhu so that the total reaches four liang and half; to resolve fluid retention and generate fluids. If there is abdominal pain, increase Renshen so that the total reaches four liang and half; this pain is due to Qi deficiency. *Ben Cao Bie Lu* (Divine Farmer's Materia Medica: Supplement) states: Renshen treats abdominal distension and pain. If cold, increase Ganjiang so that the total reaches four liang and half; if there is abdominal fullness, remove Baizhu and add one Fuzi (Aconite Lateralis Radix Preparata); this abdominal fullness is due to insufficiency of Yang Qi. After taking the medicine, after approximately the time it takes to eat a meal, drink about one sheng of hot porridge to maintain slight warmth; do not uncover clothes or blankets. Drinking hot porridge after Gui Zhi Tang (Cinnamon Twig Decoction) aims to assist the medicinal power to disperse outward; here, drinking hot porridge aims to assist the medicinal power to warm inward.
Huo Luan (Acute Vomiting and Diarrhea Syndrome) presents with headache, fever, and body ache. In the *Lun* (Treatise), it is also stated: vomiting and diarrhea constitute Huo Luan. It is also stated: headache with body ache, aversion to cold with vomiting and diarrhea constitutes Huo Luan. Observing these together, the symptoms of Huo Luan are complete; it is likely a category of Shang Han (Cold Damage). Later generations mistook vomiting and diarrhea occurring in summer heat as Huo Luan, and also used Lizhong, even creating Da Shun San (Great Harmony Powder); these are groundless arguments. If heat predominates and there is desire to drink water, Wu Ling San (Five-Ingredient Powder with Poria) is indicated; this is Huo Luan where heat overcomes cold. If cold predominates and there is no desire to drink water, Lizhong Tang (Regulate the Middle Decoction) is indicated; this is Huo Luan where cold overcomes heat.
Note: The symptoms of Huo Luan are all caused by disharmony of Cold and Heat Qi, mutual rejection of Yin and Yang, blockage of upper and lower passages, and failure of Water and Fire to interact. Wu Ling San separates clear from turbid; Lizhong Tang strengthens Yang Qi; both are treatments targeting the Middle Jiao (Middle Burner).
After recovery from a major illness, if there is a tendency to salivate excessively, it is because Stomach fluids are not retained, combined with Cold Fluid Retention, lingering indefinitely. This indicates Cold in the Stomach; it should be treated with pills for slow management. Lizhong Wan (Regulate the Middle Pill) is suitable.
