Li Dongyuan stated: Cold-type abdominal distension is common, while heat-type abdominal distension is rare; all are primarily related to the Spleen and Stomach. For deficiency patterns, Liujunzi Tang (Six Gentlemen Decoction) is appropriate. If accompanied by panting and shortness of breath, it indicates Qi deficiency of the Spleen and Lung; Yigong San (Extraordinary Efficacy Powder) should be used to tonify. If panting and distension worsen after taking purgative or attacking herbs, it signifies further injury to the Qi of the Spleen and Lung. In such cases, Banxia (Pinellia Rhizome) and Shengma (Cimicifugae Rhizoma) should be added to the previous formula. If purgation has been performed and panting ceases, it means the pathogenic factor has departed and the Lung Qi is tranquil; no medication is necessary. Alternatively, in prolonged illness, if there is difficulty in urination or edema of the four limbs, this is due to Qi deficiency of the Spleen and Lung failing to regulate water passages; Jinkui Ji Jian Shenqi Wan (Modified Kidney Qi Pill from the Golden Cabinet) is indicated. If there is cold reversal of the hands and feet, and eyes open during sleep (exposed eyes), this indicates Spleen-Stomach deficiency-cold; Liujunzi Tang with Paojiang (Prepared Ginger) should be used. If the hands and feet are not cold but eyes are exposed during sleep, this indicates Spleen-Stomach weakness; Liujunzi Tang alone should be used. If the complexion is green, it suggests Wood overacting on Earth (Liver Wood invading Spleen Earth); Liujunzi Tang, Muxiang (Aucklandiae Radix), and Chaihu (Bupleuri Radix) should be used. Furthermore, the mother’s condition should be regulated, and the child’s diet restricted, lest excessive medication re-injure Stomach Qi.
Clinical Cases:
One infant presented with abdominal distension, red face, phlegm-panting, constipation, high fever, and a desire for cold drinks. This was a pattern of excess in both form and pathology. After one dose of Zishuang Wan (White Frost Pill), symptoms worsened, the face turned pale, and the infant continuously drank hot soup. I reasoned that the pathogenic factor had receded but the True Qi was injured, hence the pale face and preference for hot soup. I prescribed a large dose of Baizhu San (Atractylodis Macrocephalae Powder) decocted in water for free consumption. After a long time, the infant slept and recovered completely the next day.
One infant suffered from abdominal distension due to food stagnation, with chest fullness and phlegm. I treated him with Yigong San, resulting in recovery. Later, he suffered from food stagnation again, presenting with abdominal distension and pain. Another practitioner used purgatives, causing severe pain and distension, accompanied by panting. This indicated Spleen-Stomach injury leading to Lung deficiency. I treated him with Liujunzi Tang plus Jiegeng (Platycodonis Radix), and he recovered after regulation and tonification.
One infant presented with abdominal distension, aversion to food, fever, and nausea, resembling an external contraction. I diagnosed this as food stagnation. One dose of Baohe Wan (Harmonize the Stomach Pill) caused immediate relief of all symptoms except abdominal distension, which was resolved using Yigong San.
One infant with abdominal distension due to food stagnation took attacking herbs, resulting in scanty and difficult urination. Subsequently, Wuling San (Five-Ingredient Powder with Poria) was administered, leading to reduced appetite, urinary retention, and sudden edema of the four limbs. I prescribed Jinkui Shenqi Wan (Kidney Qi Pill from the Golden Cabinet) without Fuzi (Aconiti Lateralis Radix Preparata) in the morning, and Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) in the evening, resulting in stabilization.
One infant with wind-cold cough and profuse phlegm was cured using Liujunzi Tang, Jiegeng, Sangbai Pi (Mori Cortex), and Xingren (Armeniacae Semen Amarum). Later, food stagnation caused diarrhea and abdominal distension; Liujunzi Tang, Shanzha (Crataegi Fructus), and Houpo (Magnoliae Officinalis Cortex) were used successfully. Subsequently, food stagnation led to vomiting. A purgative was administered, worsening the cough. I diagnosed this as dual deficiency of the Spleen and Lung and proposed regulation and tonification. The family considered this too slow and opted for releasing the exterior and resolving stagnation, which exacerbated previous symptoms and added head-shaking. I treated him with Tianma San (Gastrodia Powder) with doubled Goutenggou (Uncariae Ramulus cum Uncis) and Yigong San, leading to recovery.
A five-year-old infant developed teeth-grinding and retching after eating zongzi (sticky rice dumplings), followed by abdominal distension, unconsciousness, and nasal discoloration (green, yellow, red). This was diagnosed as Food Jue (syncope due to food) due to Spleen Earth injury. Chicken feathers were used to induce vomiting, expelling sour matter, upon which the infant woke up immediately. Dietary restriction was advised, and the infant recovered without medication.
One infant presented with chest and abdominal distension, sudden fever and stifling sensation, and crying upon abdominal palpation, indicating food stagnation. One dose of Baohe Wan relieved these symptoms. However, irritability and thirst developed, and abdominal palpation no longer caused crying. This indicated that residual food had cleared but the Spleen and Stomach were injured. Treatment with Wuwei Yigong San (Five-Ingredient Extraordinary Efficacy Powder) plus Chaihu resulted in rapid improvement.
One infant presented with abdominal distension, green-white stools, a mass on the left side of the abdomen, sallow complexion, red and ulcerated gums, poor appetite, and food residue around the mouth. I primarily used Yigong San to regulate and tonify Middle Qi, assisted by Da Wuyi Tang (Great Wormwood Decoction) to clear Gi accumulation and heat. After more than a month, symptoms improved slightly. Continued use of Yigong San and Emawang Wan (Toad Pill), along with external application ofawei Gao (Asafoetida Plaster), eliminated the mass within two months. Mild pain in the left hypochondrium remained, which was cured using Sijunzi Tang (Four Gentlemen Decoction) and Jiwei Lujian Wan (Nine-Ingredient Aloe Pill).
Hezi Wan (Brown Seed Pill) for treating Gi swelling:
Luobozhi (Brassicae Semina, 1 liang, lightly stir-fried), Chenpi (Citri Reticulatae Pericarpium), Qingpi (Citri Reticulatae Pericarpium Viride, stir-fried), Binglang (Arecae Semen), Wulingzhi (Trogopterori Faeces), Pengzhu (Curcumae Rhizoma, baked), Hei Qianniu (Stemonidis Rhizoma, first and last portions half each, stir-fried), Chi Fuling (Poria with Red Hosta Root), Muxiang (Aucklandiae Radix, 2 qian 5 fen).
Grind into powder, make pills with wheat paste, size of mung beans. Take 15 pills per dose, washed down with Perilla Decoction.
Jinkui Ji Jian Shenqi Wan (Modified Kidney Qi Pill from the Golden Cabinet):
Shudihuang (Rehmanniae Radix Praeparata, 8 liang), Ganshanyao (Dioscoreae Rhizoma), Shanzhuyu (Corni Fructus, 4 liang each), Zexie (Alismatis Rhizoma), Bai Fuling (Poria, 3 liang each), Mudanpi (Moutan Cortex), Rougui (Cinnamomi Cortex), Fuzi (Aconiti Lateralis Radix Preparata, processed), Cheqianzi (Plantaginis Semen, stir-fried), Niuxi (Achyranthis Bidentatae Radix, lightly stir-fried with wine, 1 liang each).
Grind each ingredient separately into powder. Make pills with rice paste, size of adzuki beans. Take 30–40 pills per dose, washed down with plain warm water before meals on an empty stomach.
