Pediatric cases of *Xiaochangqi* (Hernia/Intestinal Qi disorder) share the same etiology as *Shanqi* (Hernia), arising from dampness retained internally and cold pathogen constraining externally. Upon onset, symptoms include distension and pain in the lower abdomen radiating to the testicles, pain extending up to the lumbar spine, and upward rushing pain affecting the heart region, without visible swelling. Treatment should be differentiated based on symptom presentation. For cases where pain radiates to the waist, ancient methods recommend *Jiawei Xiangsu San* (Modified Fragrant Perilla Powder) to warm and disperse [pathogens] (ingredients include *Cangzhu* (Atractylodis Rhizoma), *Chenpi* (Citri Reticulatae Pericarpium), *Chuanlianyu* (Toosendan Fructus), *Gancao* (Glycyrrhizae Radix et Rhizoma), *Suye* (Perillae Folium), and vinegar-processed *Xiangfu* (Cyperi Rhizoma); use scallion whites with roots as a guiding drug, decocted with water and wine).

[Author's Note] This powder may be administered, but wine is not necessary for pediatric decoction.

For cases where pain is accompanied by qi rushing to the chest and heart, ancient methods recommend *Jiawei Shixiao San* (Modified Heartbreak Powder) (ingredients include *Wulingzhi* (Trogopteri Dung), vinegar-processed *Yanhusuo* (Corydalis Rhizoma), and vinegar-processed *Puhuang* (Typhae Pollen) in equal parts; take 1–2 qian each time, mixed with water and wine).

[Author's Note] For this powder, use 1 qian per dose, add a small amount of fine powder from *Rouguixin* (Cinnamomi Cortex interior), and mix with plain boiled water for administration, which yields superior efficacy.

If there is a palpable mass resembling an egg in the lower abdomen that moves up and down, causing unbearable pain, ancient methods recommend *Huluba Wan* (Fenugreek Pill) (ingredients include fried *Huluba* (Trigonellae Semen), *Chuanlianzi* (Toosendan Fructus) peeled and baked, each 4 qian; *Chuanwu* (Aconiti Radix) peeled and de-navelled, *Bajirou* (Morindae Officinalis Radix et Cortex) each 1.5 qian; *Huixiang* (Foeniculi Fructus) 3 qian; *Wuzhuyu* (Evodiae Fructus) soaked overnight in half wine and half vinegar then baked 2.5 qian; fried *Qianniu* (Pharbitidis Semen) 2 qian; all ground into fine powder, formed into pills using wine and wheat paste; take several pills each time, swallowed with warm wine on an empty stomach).

[Author's Note] For this condition, simply use 49 *Lizhihe* (Litchi Seed), stir-fried until charred but retaining white interior; *Chenpi* (Citri Reticulatae Pericarpium) 9 qian, stir-fried; *Dahuixiang* (Foeniculi Fructus) 5 qian, stir-fried; *Xiaohuixiang* (Foeniculi Fructus) 4 qian, stir-fried; *Zhenheichenxiang* (Aquilariae Lignum Resinatum) fine powder 1 qian; form into pills the size of mung beans using wine and wheat paste. When pain occurs, grind nine pills in light salt water and administer on an empty stomach; after some time, administer another dose. Recovery is typically achieved within three doses.

Pediatric *Linzheng* (Strangury/Dysuria) differs significantly from adult presentations and is relatively easier to treat. Investigating the etiology, it may result from wind-cold invasion or damp-heat descending into the Bladder, causing obstruction and stagnation of the water passages. Symptoms include difficulty urinating, dribbling continuously, and even complete blockage causing pain. However, differentiation must be made between cold-type, heat-type, stone-type, and blood-type strangury, with treatment tailored accordingly. The general principle is to unblock and promote the flow of water passages; mastering this approach suffices for treating all types of pediatric strangury.
