The manifestations of accumulation and mass diseases (Ji Ju Bing) vary. Da Huang (Rhubarb Rhizome) combined with Pingwei San (Calm the Stomach Powder), according to the meridian involved (accumulation in the Zang organs, gathering in the Fu organs), is used to attack the pathogen; Lizhong Tang (Regulate the Middle Decoction) is effective because it facilitates the movement of the central Qi (by regulating the central Spleen and Stomach to influence the surrounding organs). Adding Gui Zhi (Cinnamon Twig), Fu Zi (Aconite Lateral Root), Ma Huang (Ephedra Stem), and Xi Xin (Asarum Root) to Lizhong Tang allows the Great Qi (vital energy circulating in the chest) to flow and fill the body, causing the accumulations to resolve spontaneously without aggressive treatment.

Dian syndrome (Manic-Depressive Psychosis - Depressive Phase) is characterized by a dull and stupid demeanor, with patients tending to remain still. Kuang syndrome (Manic-Depressive Psychosis - Manic Phase) is characterized by unbearable restlessness and delirium, with patients tending to be active. Xian syndrome (Epilepsy) is characterized by sudden collapse and loss of consciousness, drooling from the corners of the mouth, or making sounds resembling five domestic animals, recovering after a short while, with intervals between attacks. All these conditions are caused by Phlegm-Fire. Xian syndrome often results from fright received in utero, lying dormant for a long time before manifesting. For these three syndromes, deficiency patterns are suitable for Ci Zhu Wan (Magnetite and Cinnabar Pill), while excess patterns are suitable for Gun Tan Wan (Rolling Phlegm Pill); Feng Yin Tang (Wind-Guiding Decoction) added with Huang Dan (Lead Oxide) is also effective. Since this condition is primarily due to Phlegm-Fire, it is classified under Excess Syndromes.

Dian, Kuang, and Xian are inherently difficult to treat; the guiding principle lies in the four characters "Phlegm-Fire confusing the Shen (Spirit/Mind)." Feng Yin Tang is a method from *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet); Ci Zhu Wan is for gradual treatment of slow-progressing cases, while Gun Tan Wan is for urgent pursuit of phlegm-fire in acute cases.

Food stagnation syndrome must present with symptoms such as chest tightness, belching with a putrid odor, and abdominal distension. It is suitable to use Pingwei San added with Mai Ya (Barley Sprout), Shan Zha (Hawthorn Fruit), Shen Qu (Medicated Leaven), and Lai Fu Zi (Radish Seed), stir-fried until purple, ground into powder, and taken to digest the stagnation. *Qian Jin Fang* (Prescriptions Worth a Thousand Gold) takes other herbs of similar nature, burns them to ash, administers one cun bi (a measure of volume) with wine, inducing vomiting of the retained food, leading to recovery. If the injury is recent and food remains in the diaphragm region, after taking the aforementioned decoction, induce vomiting by probing the throat with fingers, or use Gua Di San (Melon Pedicle Powder) to induce vomiting. If the injury has persisted for a long time, resulting in swelling, fullness, and tenderness upon pressure, it is suitable to purge using San Yi Cheng Qi Tang (Three-One Purging Decoction). If there are no symptoms of chest tightness or putrid belching, but only headache, aversion to cold, and fever, this is an external contraction syndrome. One must absolutely avoid using digestive/purgative agents, lest the external pathogen sink inward, causing myriad complications. In Taiyang Cold Damage (Shang Han), food intake is restricted; thus, drinking hot porridge after taking Guizhi Tang (Cinnamon Twig Decoction) is the primary principle at the beginning of the text, which becomes clear upon studying Zhang Zhongjing's works. I have observed that people in the northwest often suspect food stagnation when they are not actually suffering from it, claiming that eating certain foods, meats, or noodles on a specific day caused their illness. Doctors, trusting the patient's account and seeing poor appetite, prioritize treating food stagnation. Zhang Jingyue stated: "Who does not eat when healthy? Could it necessarily be that food stagnates beforehand waiting for disease to arrive? One can believe they do not have food stagnation." Any doctor who guesses blindly and recklessly uses purgatives should reflect upon these words. This condition belongs to internal accumulation, so it is listed under Excess Syndromes.

(Classical Meaning) The *Classic* states: "If there is pulse in the upper part but no pulse in the lower part, the person should vomit; if they do not vomit, they will die." This refers to food blocking the upper jiao, causing the pulse to vanish in the lower jiao. Why? The root of Yang Fire originates from below (earth), and the source of Yin Water comes from above (heaven/sky). Food blocking the upper part cuts off the source of the Five Zang organs; once the source is cut, water fluids cannot flow downward. When the two Chi pulses (reflecting Kidney and Lower Jiao) vanish, vomiting removes the material obstructing the Upper Jiao, and the pulse naturally reconnects. If vomiting is impossible, it is not merely a food disease, but rather the uprooting of the vital foundation, hence death ensues.
