三焦，而停食则专在胃脘也。
Shangshi (Food Injury) refers to the condition where excessive food intake, doubling the normal amount, damages the intestines and stomach. Treatment should be differentiated according to the location of the pathology in the Upper, Middle, or Lower Jiao (Triple Burner): for pathology in the Upper Jiao, induce vomiting; for the Middle Jiao, use digestion-promoting methods; for the Lower Jiao, use purgative methods.
Luo Taiwu stated: Generally, regarding the mechanism of internal injury, if the injury is slight, reducing food intake for one or two days allows the damaged food to digest naturally, which is an excellent method. If the injury is slightly severe, use medication to internally dissolve it. If the injury is too severe, use medication to purge it downwards.
Gua Di San (Melon Stalk Powder): For retained food lodged in the Upper Wan (Upper Stomach), use this formula to induce vomiting. This corresponds to the principle that "for pathology in the upper region, facilitate its expulsion upwards."
Ingredients: Gua Di (Thunberg Melon Seed, stir-fried) Chi Xiao Dou (Red Bean, boiled), equal parts.
Grind the above ingredients into a fine powder. Boil Xiang Chi (Prepared Soybean) in seven he of water to extract the juice, mix with the powder, and administer one cun bi (a measure equivalent to a teaspoon) per dose.
Another method: Mix with warm Jiang Shui (fermented rice liquid) and administer one qian bi (a small spoonful measure). Induce vomiting until relief is achieved. The Classic says: "If there is pulse at the upper part but no pulse at the lower part, the person should vomit. If they do not vomit, it is because food is blocked in the upper region, cutting off the pulse qi in the lower region." Why? The root of Yang Fire originates from below ground; the source of Yin Water comes from above heaven. Food blocking the upper region cuts off the source of the Five Zang Organs. When the source is cut off, fluids cannot flow downward, resulting in the absence of pulse at both Chi positions (radial artery position corresponding to Kidneys/Lower Jiao). Vomiting removes the stagnation in the Upper Jiao, and the pulse naturally unblocks. If vomiting cannot occur, it is not merely a food disease, but indicates the prior extraction of the root of vitality, leading to death. Alternatively, use three sheng of Yin Yang Shui (water mixed from cold and hot sources) to boil one sheng of Bai Yan (White Salt) until dissolved. Divide into three doses. Stimulate vomiting to expel the ingested food, and recovery will follow. From *Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold).
Hong Wan Zi (Red Pill): Strengthens the Spleen and Stomach, eliminates retained food, and removes distension.
Ingredients: Jing San Leng (Sparganii Rhizoma), Peng Ze (Curcumae Rhizoma), Qing Pi (Citri Reticulatae Pericarpium Viride, white membrane removed), Chen Pi (Citri Reticulatae Pericarpium, white membrane removed), each five jin; Pao Jiang (Zingiberis Rhizoma Preparatum), Hu Jiao (Piperis Longi Fructus), each three jin.
Grind the above into powder. Mix with vinegar and flour to form pills the size of Sophora seeds (Wu Zi). Coat with Fan Hong (Alum Red). Administer thirty pills per dose after meals, washed down with Ginger Decoction. *Yi Jian Fang* contains a formula using A Wei (Ferulae Resina) to treat food accumulation forming masses.
Boil Zi Su (Perillae Folium) in concentrated decoction, add Xing Ren (Armeniacae Semen Amarum) paste. Ingestion disperses the accumulation.
For treating indigestion of dog meat, presenting with hardness under the heart, abdominal distension, dry mouth with extreme thirst, mental agitation with fever, delirious speech, or watery diarrhea.
Take one sheng of Xing Ren (Armeniacae Semen Amarum), remove skin and tips, grind. Add three sheng of boiling water, mix and squeeze out the juice. Divide into three doses. Remove all original pieces of dog meat, or decoct Lu Gen (Phragmitis Rhizoma) and drink it to aid digestion.
*Qian Jin* Formula for Treating Undigested Food
Take other remaining types of food, burn them into powder, administer with wine using a fang cun bi (square-inch spoonful) measure. Vomiting up the retained food leads to cure.
Commentary: When food stagnates in the Zhong Wan (Middle Epigastrium), although medicinal power assists in digestion, the agent mobilizing this medicinal power is Wei Qi (Stomach Qi). Therefore, in cases where repeated use of food-digesting and Qi-moving drugs fails to resolve the stagnation, I subsequently add one or two qian of Ren Shen (Ginseng Radix et Rhizoma) to the previously used formulas, achieving miraculous results. Students must understand this.
Bei Ji Fang (Emergency Preparedness Formula): Treats sudden, stabbing pain in the heart and abdomen caused by overconsumption of cold foods/drinks.
Ingredients: Chuan Da Huang (Rhei Radix et Rhizoma, powdered), Gan Jiang (Zingiberis Rhizoma, powdered), Ba Dou (Crotonis Fructus, skin and heart removed, ground, oil removed to use as residue/frost).
Mix equal parts of the above, grind uniformly. Form pills with refined honey, size of Vicia seeds. Administer one pill with warm water. For excess conditions, add one more pill. Another version states: Administer three pills per dose. If ineffective, take three more. When abdominal borborygmus occurs, vomiting or purging will lead to recovery.
Dong Yuan Dao Zhi Wan (Dong Yuan's Guide-Stagnation Pill): Treats damage from damp-heat substances that fail to transform immediately, resulting in fullness, oppression, restlessness, and constipation.
Ingredients: Huang Qin (Scutellariae Radix), Fu Ling (Poria), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Huang Lian (Coptidis Rhizoma), each three qian; Ze Xie (Alismatis Rhizoma), two qian; Zhi Shi (Aurantii Fructus Immaturus), Shen Qu (Massa Medicata Fermentata), each half liang; Da Huang (Rhei Radix et Rhizoma).
Grind into powder. Soak in decoction, steam with leavened bread dough to form pills. Take fifty pills after meals, washed down with boiling water.
He Nian stated: Shangshi (Food Injury) and Ting Shi (Food Retention) should be distinguished into two categories. Shangshi refers to doubling food intake, damaging the intestines and stomach, where the pathology lies in the inability to digest in time. Ting Shi, regardless of quantity, occurs when one eats while angry or sick, causing Qi knotting and failure to transform. Treatment for Shangshi should focus primarily on resolving food, using vomiting, purging, or digestion-promoting methods. For Ting Shi, the focus should be on regulating Qi, combining it with digestion; vomiting and purging methods are contraindicated. Generally, Shangshi should be treated by differentiating the Upper, Middle, and Lower Jiao, whereas Ting Shi is specifically located in the Stomach Wan (Epigastrium).
