伤食者，必恶食嗳腐，吞酸痞胀，腹满倦怠气急。或腹痛，或吐泻，或秘结，或发热，皆为伤食
之候。经曰∶饮食自倍，肠胃乃伤。虞天民云∶凡伤食者，皆原中气不足，宜以补益为要，但治法有
先后，不可倒施。故物伤之际，积食未行，遽用补益，则滋其壅塞，病必增剧。必先用顺气消食化痰
之药，待宿食消行，然后平调，继以补益，始治之有序，而获宁矣。又沈氏云∶治伤食而但用消导，
庸愚尽晓，须审致病有寒热虚实之不同，或挟外感，或挟气挟痰，或久病，或产后，治各有异。如寒
者热之，热者寒之，虚者补而消之。若血虚者，兼养血而食自行；若气虚者，兼补气而食自化。实者
削而消之。如食在上，胸膈饱闷不安者，探吐之；如食在下，绕脐疼痛，手不可按者，攻下之。
挟外感者，当以解散表邪为主，而带和中；挟痰气者，当以开痰行气为主，而兼消导。久病产后，皆
宜调补脾胃为主，
而佐以顺气消食之剂，不可专行克削攻下，恐宿食未消，而元气顿削，以致变幻不测。余每见世人，
以伤食为小疾，而医者亦遂轻忽以施治，故死于伤食者甚多。经曰∶脾胃为后天之根本，根本既伤，
而又不善治之，安望其得生耶！

Shangshi (Food Injury) inevitably presents with aversion to food, belching with a putrid odor, acid regurgitation, chest and epigastric stuffiness and distension, abdominal fullness, fatigue, and shortness of breath. It may also manifest as abdominal pain, vomiting and diarrhea, constipation, or fever; all these are signs of Shangshi. The *Classic of Internal Medicine* states: "If food and drink exceed normal intake by double, the intestines and stomach will be injured." Yu Tianmin said: "The root cause of all cases of Shangshi is deficiency of Middle Qi; treatment should prioritize tonification. However, therapeutic methods must follow a specific sequence and cannot be reversed. When food injury first occurs and accumulation has not yet moved, if tonifying medicines are used immediately, they will exacerbate stagnation, and the condition will surely worsen. One must first use herbs that promote Qi circulation, digest food, and resolve phlegm. Only after the retained food has been digested and moved can one proceed to harmonize and regulate, followed by tonification. This ensures an orderly treatment process and leads to recovery." Additionally, Mr. Shen stated: "Merely using digestive and guiding methods for Shangshi is knowledge known even to mediocre physicians; one must examine whether the etiology involves Cold, Heat, Deficiency, or Excess, or if it is complicated by external pathogens, Qi stagnation, or Phlegm, or if it occurs after prolonged illness or postpartum. Treatments vary accordingly. For Cold patterns, treat with Heat; for Heat patterns, treat with Cold; for Deficiency patterns, treat with Tonification combined with digestion. If Blood is deficient, nourish Blood alongside digestion so that food transforms naturally; if Qi is deficient, tonify Qi alongside digestion so that food transforms naturally. For Excess patterns, use reduction and digestion. If food stagnates in the Upper Jiao, causing chest and diaphragmatic fullness and discomfort, induce vomiting; if food stagnates in the Lower Jiao, causing periumbilical pain and tenderness upon palpation, use purgatives. If complicated by external pathogens, focus on releasing the exterior while harmonizing the middle; if complicated by Phlegm and Qi stagnation, focus on resolving Phlegm and moving Qi while assisting digestion. For prolonged illness and postpartum conditions, prioritize regulating and tonifying the Spleen and Stomach, assisted by herbs that move Qi and digest food. Do not exclusively use harsh reducing or purgative methods, lest the retained food remain undigested while Yuan Qi is suddenly depleted, leading to unpredictable complications. I often see people regard Shangshi as a minor ailment, and physicians consequently treat it lightly; thus, many die from Shangshi. The *Classic of Internal Medicine* says: 'The Spleen and Stomach are the foundation of the Post-Heaven. If the foundation is injured and not treated properly, how can one expect survival?'
Baohe Wan (see Diarrhea).
For cold damage accompanied by Cold, remove Lianqiao (Forsythiae Fructus) and add Xiangfu (Cyperi Rhizoma), Sharen (Amomi Fructus Rotundus), Chenxiang (Aquilariae Lignum Resinatum), and Baixiaoren (Amomi Fructus).
For bitter taste in the mouth, dry tongue, and internal Heat, remove Banxia (Pinelliae Rhizoma Preparatum) and add Zhishi (Aurantii Fructus Immaturus), Huanglian (Coptidis Rhizoma), and Maidong (Ophiopogonis Radix).
For distension, abdominal pain, hardness upon palpation, or presence of masses, add Zhike (Aurantii Fructus), Houpo (Magnoliae Officinalis Cortex), Binglang (Arecae Semen), and Ezhu (Curcumae Rhizoma).
This formula promotes Qi circulation, digests food, and resolves phlegm; it is a key prescription for treating Shangshi. Use with modifications for Excess patterns.
Da Chengqi Tang (see Cold Damage). The *Jin Gui Yao Lue* states: "When a patient has abdominal fullness, non-tenderness upon palpation indicates Deficiency, while tenderness indicates Excess; purgatives may be used. If yellow coating remains on the tongue, purging will cause the yellow coating to disappear." It further states: "Abdominal pain with constipation requires purging." It also states: "Diarrhea with loss of appetite indicates retained food; purging is required." Additionally: "A slippery and rapid pulse indicates Excess due to retained food; purging leads to cure." Furthermore: "In cases of retained food, the Cun (inch) position pulse is floating and large [abundant Grain Qi can also present as floating and large]. Upon deep pressure, it feels choppy [irregular diet damages Yin and Blood first, hence the choppy feeling amidst the floating-large quality, indicating retained food]. The Chi (cubit) position is also faint and choppy [food obstruction in the Middle Jiao blocks Qi flow, and the Lower Jiao loses its source of transformation, hence faint and choppy]. Purging is indicated [to prevent rapid depletion of fluids, essence, and blood, which would make resolution difficult]. All such cases are managed with this formula.
This is a purgative formula for scouring and cleansing. It should only be used when symptoms match those above, specifically retained food in the Lower Jiao with periumbilical pain and tenderness. Mangxiao (Natrii Sulfas) may be omitted, replaced with Xuánmíngfěn (Natrii Sulfas Depuratus), or alternatively, Mengshi Guntan Wan (Calcareous Schist Phlegm-Rolling Pill) or Xiangdan Wan (Elephant Bile Pill) may be selected according to suitability. An ancient formula, Beijijian Wan (Emergency Prepared Pill), uses Bashuang (Crotonis Seminis Extract) 1 qian, Dahuang (Rhei Radix et Rhizoma) and Ganjiang (Zingiberis Rhizoma) 5 qian each, honey-pilled to the size of mung beans. Take one pill per dose, stopping when bowel movement occurs. This method is for Cold accumulation; record this method for clinical reference.
Ganji San (Infantile Malnutrition Powder): Treats infantile malnutrition due to irregular breastfeeding/diet, overeating damaging the Spleen, presenting with sallow complexion, distended abdomen, turbid urine resembling rice water, yellow acidic foul-smelling stool, dry and sparse skin and hair, photophobia and corneal opacity in severe cases, emaciation, night fever and daytime coolness, etc.
Houpo (Magnoliae Officinalis Cortex) [digests food accumulation, stir-fried with ginger juice, 1 liang], Juhong (Citri Reticulatae Pericarpium Rubrum) [moves stagnant Qi, 8 qian], Gancao (Glycyrrhizae Radix et Rhizoma) [harmonizes the middle], Zhenlushui (Aloe), Wuyi (Chrysanthemi Indici Flos) [each 5 qian], Qingdai (Indigo Naturalis) [all kill parasites and clear malnutrition heat], Baicaoshuang (Carbonis Herbae) [resolves accumulation], Xuanjinhua (Inulae Flos) [dissolves hard phlegm, each 2 qian]. (Grind these eight ingredients into fine powder. For children, administer 1 fen per year of age, mixed with Dengxincao (Junci Medullae) decoction on an empty stomach. Once half the accumulation is resolved, switch to Fei'er Wan for regulation.)
Fei'er Wan (Spleen-Nourishing Pill): Highly effective for infantile malnutrition.
Renshen (Ginseng Radix et Rhizoma) [3 qian], Baishao (Paeoniae Radix Alba), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma) [mixed with Sharen (Amomi Fructus Rotundus) 5 qian each, others 1 liang each], Bian Dou (Dolichoris Semen), Lianrou (Nelumbinis Semen) [strengthen Spleen], Shanzha (Crataegi Fructus), Maiya (Hordei Fructus Germinatus), Hongqu (Monascus Rice), Juhong (Citri Reticulatae Pericarpium Rubrum), Sharen (Amomi Fructus Rotundus) [digest food], Huanglian (Coptidis Rhizoma), Shijunzi Rou (Quisqualis Semen), Wuyi (Chrysanthemi Indici Flos), Qingdai (Indigo Naturalis) [clear heat and kill parasites], Huashi (Talcum) [clear heat and guide out stagnation]. Total sixteen ingredients. Honey-pilled to the size of a bullet. Take one pill per dose, dissolved in warm water on an empty stomach.
Shibao Wan (Ten-Treasure Pill): Treats adult and pediatric jaundice due to food accumulation, and pediatric malnutrition.
Pingwei San plus Shan Zha Rou (Crataegi Fructus), Maiya (Hordei Fructus Germinatus), Binglang (Arecae Semen), Fuling (Poria) [each 2 liang], Lüfan (Vitriolum Viride) [effectively digests food accumulation and treats various jaundices, vinegar-treated until red, 4 liang]. Lifelong avoidance of buckwheat and pufferfish is required; ingestion causes death. Form pills with jujube flesh to the size of sophora seeds. Take 1 qian per dose with warm water, three times daily. After administration, press down the medicine with food.
These three formulas are miraculous agents for treating pediatric malnutrition, proven effective through repeated trials.
Yigong San (Benefit the Work Decoction), Guipi Tang (Restore the Spleen Decoction), Liu Junzi Tang (Six Gentlemen Decoction) [see Stroke].
May additionally include Xiangfu (Cyperi Rhizoma), Sharen (Amomi Fructus Rotundus), Chenxiang (Aquilariae Lignum Resinatum), Baixiaoren (Amomi Fructus), Shanzha (Crataegi Fructus), and Maiya (Hordei Fructus Germinatus).
Zisheng Wan (Life-Nourishing Pill) [see Consumption].
These four formulas employ a method of tonification combined with digestion. Use with modifications for Deficiency patterns. According to *Yi Guan*: "If Yuan Qi in the Stomach is abundant, one can eat without injury and feel no hunger past meal times. If Yuan Qi is deficient, one easily suffers food injury. Using purely Qu (Medicated Leaven), Houpo, Shanzha, and Maiya merely seeks temporary relief. Have they not considered that if the Spleen is already injured, subjecting it to further digestion depletes its deficiency further, making future food injury more likely." Thus, those who consume rich foods differ from those who consume coarse foods. Those eating coarse foods and robust may use Baohe Wan or Da Chengqi Tang; applying these methods indiscriminately to those consuming rich foods who are weak causes significant harm.
Guangbiji Fang (Recorded Notes Formula): Treats elderly patients with cold food injury and indigestible items.
Shengjiang (Zingiberis Rhizoma Recens), Zisu (Perillae Folium) [boil into strong decoction, place in bath tub, let patient soak and steam in the hot liquid].
This method utilizes acrid-warm properties to unblock Qi; once Qi flows freely, food digests naturally.
