Excessive intake of food and drink causing injury can transform into abnormal, acute, and violent syndromes, which most people do not recognize. I once encountered a robust young man who suddenly fell ill with an acute condition resembling stroke (Zhong Feng), unable to speak, failing to recognize people, and unable to move his four limbs. He was urgently administered Suhexiang Wan (Styrax Pill), but it was ineffective. By chance, I passed by and heard of this, so I inquired about the cause. He replied that he had just finished dining with guests when he suddenly developed this syndrome. I then instructed him to decoct ginger light salt soup, drink it in large quantities, and induce vomiting by stimulating the throat. After vomiting several bowls, he regained consciousness. Later, he took Baizhu (Atractylodis Rhizoma), Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), and Maiya (Hordei Fructus Germinatus) for conditioning and recovered. Generally speaking, such syndromes are mostly caused by dietary stagnation after overeating or drinking to excess, compounded by exposure to wind-cold or emotional anger, leading to food blocking the stomach qi's movement, resulting in severe internal injury. If mistakenly treated as stroke or qi stagnation, and drugs for expelling wind, releasing the exterior, moving qi, or dispersing qi are used, the stomach qi will be severely damaged, and death may occur within a day or two. Although the *Neijing* (Classic of Internal Medicine) records syndromes of sudden illness and sudden death, many are likely due to food issues. Previous experts did not explicitly state this, hence people's lack of understanding! In the future, when encountering such acute syndromes, one must inquire carefully. If the patient has just eaten or drunk to fullness, or has suffered repeated dietary injuries, and feels food stagnation in the chest and diaphragm, treat it solely as food injury (Shang Shi).

I once treated Censor Zhao, who vomited acidic substances. His pulse at the Qi Kou (Radial Artery Point) was two to three times larger than that at the Ren Ying (Carotid Artery Point). Colleagues urgently asked me to prescribe medication. I said: "This is excess pathogen located above; wait until he vomits all the acid, and he will recover without medication." The next morning, vomiting ceased, and he was safe.

A woman, after eating and drinking, became angry and suddenly suffered from blood flooding (Xue Beng - massive uterine bleeding outside the menstrual period). Her four limbs were cold, she experienced convulsions, lockjaw, and symptoms resembling spasm (Jing Bing), with profuse expectoration of phlegm. She was given Erchen Tang (Two-Cured Decoction), Chaihu (Bupleuri Radix), Zhizi (Gardeniae Fructus), and Zhike (Aurantii Fructus Pericarpium). After vomiting acidic fluid, her mental state slightly improved. Medication was stopped. The next day, she consumed a small amount of thin porridge but presented with distending pain in the breasts and hypochondrium, alternating chills and fever, desire to vomit, and limb fatigue. I considered all these symptoms to belong to blazing liver fire (Gan Huo), causing the spleen qi to fail in transformation and transportation. I first used Liujunzi Tang (Six-Gentlemen Decoction), Chaihu, Zhizi, and Goutenggou (Uncariae Ramulus cum Uncis) to quickly alleviate various symptoms. However, only inability to move the four limbs freely and blood flooding remained as before. Others argued that the liver fire had not subsided and wanted to administer formulas for clearing liver heat and cooling blood. I believed that both liver and spleen qi and blood were weak. I first used Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) to nourish spleen earth, allowing qi and blood to return to their vessels. Then, I used Siwu Tang (Four-Substance Decoction), Renshen (Ginseng Radix), Baizhu, and Chaihu to nourish liver sinews, thereby facilitating free movement of the four limbs.
