After weaning, infants begin to consume solid food. During the summer months, when the Spleen and Stomach are in their dominant phase, it is easy for them to develop abdominal distension, diarrhea, heat in the head, heat in the palms and soles, and progressive emaciation. Alternatively, they may present with irritability, thirst, and hyperphagia, gradually evolving into the "Five Gu" (Pediatric Malnutrition Syndromes) and accumulation disorders. One must assess the strength of the child's constitution and the duration of the disease. If it is an excess syndrome, one should regulate the Stomach Qi and clear Heat; if stools are white after eating or food is undigested, one should strengthen the Spleen and assist with digestive-promoting and heat-clearing methods. If Damp-Heat is internally constrained with intestinal parasites causing abdominal pain, use methods to guide out stagnation and expel parasites with mild purgation; during the convalescent phase, use formulas such as Fei'er Wan (Child-Nourishing Pill) for regulation.

From summer to early autumn heat, pediatric diarrhea occurs, or the condition has just healed but not fully resolved, leading to Gu erosion ulcers covering the entire mouth. There have been cases where throat obstruction led to critical danger. These are all due to excessive internal Dampness generating Heat, with Heat steaming and scorching, preventing Jin-Ye (Body Fluids) from ascending, and Damp-Heat disproportionately injuring the Qi aspect. Treatment should focus on the Upper Jiao (Upper Burner), possibly assisted by light diuretic and damp-draining agents. Secular practice often uses scraped watermelon rind (Xi Gua Cui Yi) to treat Gu diseases, taking advantage of its light, ascending, and damp-draining properties.

In summer, Damp-Heat is constrained and steaming, while Spleen and Stomach Qi is weak, failing to transport the essence of water and grain. The warming Qi accumulates internally transforming into Heat, gradually leading to edema, abdominal distension, and difficult urination. If treated incorrectly, long-term immersion in Water-Dampness reverses upward to invade the Lung, inevitably causing cough and panting/shortness of breath, severe enough that the patient cannot lie flat, nor can they bend forward or extend backward, indicating an imminent critical period. Generally, panting generates distension, and distension generates panting. Medical texts state that if panting precedes distension, the pathology is in the Lung; if distension precedes panting, the pathology is in the Spleen. This is a definitive conclusion. *Jin Gui Yao Lue* classifies Feng Shui (Wind Edema), Pi Shui (Skin Edema), Shi Shui (Stone Edema), Zheng Shui (Regular Edema), and Huang Han (Yellow Sweat) to distinguish between exterior and interior treatments. Liu Hejian proposed San Jiao Fen Xiao (Separate Elimination via the Three Burners), and Zhang Hezi advocated Mo Ji Zhu Shui (Grinding Accumulations and Driving Out Water), both containing profound principles. Students must ponder and recognize these deeply; they cannot be summarized here. Reading recent secular discussions on Water-Dampness, panting, and distension syndromes, which cite *Nei Jing*'s "Kai Gui Men" (opening the ghost gate/sweating) as exterior treatment and separating/diuresis ("Jing Jian Fu") as interior treatment: *Su Wen - Bing Neng Pian* states that all dampness, swelling, and fullness belong to the Spleen, advocating strengthening the Spleen and drying Dampness as a stable treatment. If this fails, practitioners are at a loss. They fail to realize that all diseases originate from Yin-Yang imbalance. Releasing the exterior and promoting urination is to circulate Jing Qi and facilitate Fu organ Qi; this is the treatment method for Yang diseases. Warming the Water Organ (Kidney) and warming the Spleen-Kidney, using tonifying formulas to drive out water, is the treatment method for Yin diseases. Treating Lung Bi requires gently opening the Upper Jiao; treating Spleen disorders must be assisted by warming and unblocking methods. If Yin-Yang and exterior-interior relationships are disordered, and Zhen Qi (True Qi) of the organs declines daily, with Yin-Yang circulation stagnant, distension will also occur. Treatment should focus on unblocking Yang Qi to achieve results. For example, Yu Yu Liang Wan from *Ju Fang*, or even when the Three Burners are mutually obstructed, Fen Xiao (separate elimination) must be used; when the intestines and stomach are blocked, Xia Duo (purging/downward draining) must be used. However, this cannot be equated with Excess-Heat in Shang Han (Cold Damage); arbitrarily administering Xing (Niter), Huang Qin (Rhubarb), Zhi Shi (Immature Bitter Orange), and Hou Po (Magnolia Bark) will disturb Yin Blood. If Taiyin Spleen Cold-Fluid and Dampness obstruct Qi, and warming/tonifying fails, and one wishes to use purgation, Gan Sui (Kansui Root) can be used in small amounts made into pills. The methods selected for treating excess syndromes are detailed in the collected references.
