Treatment for discomfort, fullness, nausea with urge to vomit, restlessness, and anxiety caused by heat-inducing food stagnation:
Gancao (Radix Glycyrrhizae Preparata), Shengma (Rhizoma Cimicifugae), Chaihu (Radix Bupleuri) (each 3 qian), Huanglian (Rhizoma Coptidis, washed in wine, 1 liang), Huangqin (Radix Scutellariae, 2 liang).
Another prescription adds Zhishi (Fructus Aurantii Immaturus, 5 qian).
Grind the above ingredients into a fine powder. Soak in decoction, mix with dough, and form pills the size of mung beans. Take 50 pills per dose, swallowed with warm water after meals.

For injuries caused by consuming frozen beverages, use Wuling San (Five-Ingredient Poria Pill). Take 2 or 3 qian/bi per dose, decocted with fresh ginger slices.

For cases involving both food injury and injury from frozen beverages, decoct Wuling San and use it to deliver Banxia Zhizhu Wan (Pinellia and Atractylodes Macrocephala Pill).

For injuries from frozen beverages without aversion to cold, where the abdomen does not feel cold but there is only a sensation of heaviness, chest stuffiness, indigestion, or difficulty in urination, decoct Wuling San with Gui Zhi (Ramulus Cinnamomi Cassiae) removed, and adjust the dosage according to the aforementioned principles.

When the pulse is present in the upper part (cun position) but absent in the lower part (chi position), the patient should vomit; if unable to vomit, it indicates a fatal condition. What is meant by "absent pulse in the lower part"? This refers to Wood Stagnation (Liver Qi Stagnation). Overeating fills the chest. The chest is the domain governed by the Taiyin (Spleen/Lung) channels. The medical classics state: "The Qikou (radial artery at the wrist) pulse is three times larger than the Renying (carotid artery) pulse," indicating that food damage affects the Taiyin channel. Therefore, it is said: "When Wood is stagnant, it must be dispersed." Vomiting is the method to achieve this.
Gudie (Fructus Momordicae), Chi Xiaodou (Semens Phaseoli Angularis) (equal parts).
Grind these two ingredients into an extremely fine powder. Take 2 qian/bi per dose, mixed with warm Jiangshui (fermented rice water). Induce vomiting as the goal. If the chi pulses are completely imperceptible in both hands, do not use this medicine immediately, as it may damage Yuanqi (Primal Qi) and prevent the recovery of Weiqi (Stomach Qi). If there is merely chest stuffiness, oppression, and blockage, one may induce vomiting by stimulating the throat with a finger; if ineffective, use an object to stimulate the throat. Vomiting resolves the issue. If the food remains, use this medicine again to induce vomiting.
Explanation: When excessive food fills the chest, causing obstruction, the cun pulses should be prominent while the chi pulses are absent. Why? Because food resides in the chest. Food belongs to Wu (things), which corresponds to Kun Earth, representing the Foot Taiyin Spleen. The chest belongs to the Lung, Hand Taiyin Metal. Metal governs killing and cutting. Both Kun Earth and Metal reside in the upper jiao and are prosperous in the Heaven aspect. Metal overcomes Wood, so the ascending energy of Liver Wood is suppressed underground. Is this not Wood Stagnation? By vomiting out the Yin-Earth substances from the Upper Jiao, Wood Qi can expand freely, resolving the stagnation. When food blocks the upper body, the pulse disappears below. Without understanding the Way of Heaven and Earth, one cannot comprehend this profound principle.
Water and Fire are manifestations of Yin and Yang, and alternate names for Earth and Heaven. Thus, it is said: "Solitary Yang does not generate; solitary Yin does not grow." The function of Heaven lies beneath the Earth, allowing all things to grow; the function of Earth lies above in Heaven, allowing all things to be stored. This is the communication between Heaven and Earth through which all things flow smoothly—the way Heaven and Earth root each other. Therefore, the root of Yang Fire is in the Earth, and the source of Yin Water is in Heaven. Hence, it is said: "Water flows from high sources." The five Zang organs govern有形 (material) things. Things belong to Yin, and Yin belongs to Water. These are controlled by the three positions on the right hand (cun, guan, chi). When the pulse manifests predominantly at the cun position, it is because food has blocked two of the three positions, severing the source of the five Zang organs. When the source is severed, Water cannot flow downward, leading to the exhaustion and absence of the chi pulses. What is there to doubt in this logic?
If the injured foods differ in nature, calculate the ratio: assume heat-inducing food accounts for two parts, and cold/raw/hard food accounts for one part. Use Sanhuang Wan (Three-Yellow Pill, a cold-natured formula) in two portions and Badou Sanleng Wan (Croton and Curcuma Pill, a hot-natured formula) in one portion, mixed and taken together. If heat-inducing food causes less injury and cold-inducing food causes more, then use less cold medicine and more hot medicine.
For example, during the intense heat of summer, if one injures themselves with cold/raw/hard food, one should use the hot medicine Badou Sanleng Wan. However, one must add Sanhuang Wan because the seasonal climate is hot and should not be violated; thus, cold medicine is added to harmonize with the season. If only heat-inducing food is injured, Sanhuang Wan alone suffices. Why is Sanhuang Wan considered a "seasonal medicine"? For instance, during the severe cold of winter, if one injures themselves with heat-inducing foods like lamb or wet noodles, one should use Sanhuang Wan but must add a small amount of hot medicine, such as Caodoukou Wan (Cardamom Pill), as a guiding agent and seasonal adjustment. The classics state: "One must first understand the annual qi (climate) and not violate the Harmony of Heaven." This is what is meant. All other cases follow this pattern.
