Angelicae Sinensis Radix (Danggui, 当归) three liang, Zingiberis Rhizoma Recens (Shengjiang, 生姜) five liang, Mutton (Rou, 羊肉) one jin.
The above three ingredients are boiled in eight sheng of water to obtain three sheng of decoction. Take seven he of the warm decoction orally, three times a day. If cold pathogen is severe, increase Shengjiang (Zingiberis Rhizoma Recens) to one jin. If pain is severe accompanied by vomiting, add Citri Reticulatae Pericarpium (Chenpi, 橘皮) two liang and Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) one liang. When adding Shengjiang (Zingiberis Rhizoma Recens), also add five sheng of water, boil to obtain three sheng and two he, then take.

Cold hernia (Han Han, 寒疝 - abdominal cramping pain due to cold), with abdominal pain, cold limbs, numbness and insensitivity of hands and feet, and if accompanied by body pain, which cannot be cured by moxibustion, acupuncture, or various medicines, should be primarily treated with Wutou Guizhi Tang (Cinnamon Twig and Aconite Decoction).
[Note]
The characters "Di Dang" are superfluous.
[Annotation]
Cold hernia causing abdominal pain, cold limbs, numbness of hands and feet, and body pain indicates a severe case of cold hernia. Since moxibustion, acupuncture, and various medicines have failed to produce effects, it is urgent to use Wutou Jian (Aconite Decoction) combined with five he of Guizhi Tang (Cinnamon Twig Decoction) to resolve the severe cold inside and outside the body.
[Collected Notes]
Xu Bin said: The condition starts with cold hernia abdominal pain, progressing to cold limbs and numbness of hands and feet, indicating severe obstruction of Yang Qi. Coupled with body pain, both Ying (Nutritive) and Wei (Defensive) Qi are disordered. At this point, even if moxibustion, acupuncture, and various medicines fail to cure, it is because whether attacking externally or internally, the pathogenic factors constrain each other and do not submit. Therefore, Wutou (Radix Aconiti Lateralis Preparata) is used as the main agent to attack cold, combined with the complete Guizhi Tang (Cinnamon Twig Decoction) to harmonize Ying and Wei Qi. This is what is meant by treating seventy percent internally and thirty percent externally.

Wutou (Radix Aconiti Lateralis Preparata) five pieces.
The above single ingredient is boiled in two jin of honey until reduced by half. Filter out the dregs, then dissolve the residue using five he of Guizhi Tang (Cinnamon Twig Decoction) to obtain one sheng in total. Initially take two he; if there is no response, take three he; if still no response, increase to five he. If the patient experiences a sensation like drunkenness, or vomits, it indicates that the medicine has hit the target (Zhong Bing, 中病).
[Formula Analysis]
"Dissolving with five he of Guizhi Tang (Cinnamon Twig Decoction)" means melting/dissolving. "Obtaining one sheng" refers to mixing five he of the honey-decocted Wutou liquid with five he of Guizhi Tang (Cinnamon Twig Decoction) to melt and obtain one sheng. "No response" means ineffective; "again no response" means still ineffective upon re-administration; "having response" means effective. The drunken-like state indicates that external cold is dissipating. Vomiting indicates that internal cold is being expelled, thus termed "hitting the target."

Question: How can one distinguish patients with retained food (Su Shi, 宿食)? The Master said: The pulse at Cun Kou (Inch Position) is floating and large, but feels choppy upon deep pressure; the Chi position (Cubit Position) is also slightly choppy. Thus, we know there is retained food, and Da Chengqi Tang (Major Order the Qi Decoction) should be used.
[Note]
The character "Wei" (slight) in "Chi position is also slight and choppy" should be corrected to "Da" (large) according to Shanghan Lun (Treatise on Cold Pathogenic Diseases).
[Annotation]
Su Shi disease (retained food disease) is equivalent to modern food stagnation, referring to food that remains undigested overnight. When a person suffers from abdominal fullness and pain, how do we distinguish it as retained food? The Cun Kou pulse is floating and large, feeling large, choppy, and forceful upon pressing; Guan (Bar Position) and Chi positions are similar. A pulse that is large, choppy, and forceful indicates excess syndrome with obstructed flow, thus confirming retained food. Purging method should be applied, and Da Chengqi Tang (Major Order the Qi Decoction) is suitable.

A rapid and slippery pulse indicates an excess syndrome, signifying retained food. Purging will lead to recovery; Da Chengqi Tang (Major Order the Qi Decoction) is suitable.
[Annotation]
Abdominal fullness and pain with a rapid and slippery pulse indicate an excess syndrome caused by retained food; therefore, purging should be applied.
[Collected Notes]
Li [Name] said: Slippery pulse indicates abundance of Qi from water and grain. If slippery pulse is accompanied by rapid pulse, it means excess heat has entered the Stomach Fu organ. Hence, it is stated that retained food can be treated by purging.

Diarrhea accompanied by loss of appetite indicates retained food. Purging should be applied; Da Chengqi Tang (Major Order the Qi Decoction) is suitable.
[Annotation]
Initial diarrhea with loss of appetite indicates food injury, characterized by aversion to food or lack of desire to eat. Prolonged diarrhea with loss of appetite indicates Spleen damage and inability to digest food. Now, initial diarrhea with loss of appetite is due to retained food. Purging should be applied, and Da Chengqi Tang (Major Order the Qi Decoction) is undoubtedly suitable.
[Collected Notes]
Shen Mingzong said: This is diarrhea caused by food injury. Sudden excessive intake of retained food stagnates in the Stomach, blocking the mechanism of ascending and descending. Water and grain fail to transform in the intestines, leading to separation failure and downward rushing, resulting in diarrhea. Because retained food stays in the Stomach, there is no desire to eat. It is necessary to attack and remove the retained food; once diarrhea stops and appetite returns, Da Chengqi Tang (Major Order the Qi Decoction) is suitable.

Retained food located in the Upper Wan (Upper Part of the Stomach) should be treated by inducing vomiting; Gua Di San (Melon Tip Powder) is suitable.
[Annotation]
The Stomach is divided into Upper, Middle, and Lower Wan. For retained food in the Upper Wan, symptoms include pain in the diaphragm region and vomiting; vomiting method can be used, but purging method cannot. For retained food in the Middle Wan, symptoms include heart pain with vomiting, or pain without vomiting; both vomiting and purging methods can be used. For retained food in the Lower Wan, symptoms include pain above the umbilicus without vomiting; vomiting method cannot be used, only purging method. Since the food is currently in the Upper Wan, Gua Di San (Melon Tip Powder) should be used to induce vomiting.
