Abdominal pain in children, accompanied by cold breath from the mouth and loss of appetite, indicates deficiency-cold of the Spleen Earth. It should be primarily treated with Tiaozhong Wan (Regulate the Middle Pill). If the breath is warm and the stool has a sour, foul odor, it is pain due to food accumulation; it should be treated with Xiaji Wan (Drain Accumulation Pill). If the face is red with high fever, or both hands and feet are hot, it is excess-heat; it should be cleared using Xiehuang San (Drain Yellow Powder). If the face is yellow with slight fever, or both hands and feet are warm, it is deficiency-heat; it should be tonified using Yigong San (Extraordinary Efficacy Powder). If there is thirst and a desire to drink hot water, it is deficiency-heat of the Stomach Qi; use Baizhu San (Atractylodes Macrocephala Powder). If abdominal pain radiates to both hypochondria, it is Liver Wood overacting on Spleen Earth; use Sijunzi Tang (Four Gentlemen Decoction) added with Chai Hu (Bupleuri Radix) and Shaoyao (Paeoniae Radix). If abdominal pain is accompanied by a heavy, bearing-down sensation, it is sinking of Spleen Qi; use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with Shengma (Cimicifugae Rhizoma). If the fingers and toes are cold, or if there is hiccups and diarrhea, it is Cold Water insulting Spleen Earth; use Liujunzi Tang (Six Gentlemen Decoction) with Paojiang (Prepared Zingiberis Rhizoma) and Rougui (Cinnamomi Cortex); if ineffective, urgently add Fuzi (Aconiti Lateralis Radix Praeparata). If abdominal pain occurs after taking drugs that attack stagnation, but pressing the abdomen does not cause pain, this indicates re-injury to Spleen Qi; use Wuwei Yigong San (Five-Ingredient Extraordinary Efficacy Powder). Pain at the Zhongwan point (CV12) belongs to the Spleen. Pain in the lower abdomen belongs to the Kidney. Pain aggravated by pressure indicates stagnation; pain not aggravated by pressure indicates interior deficiency. Stagnation is treated by resolving/dispersing; interior deficiency is treated by tonifying.
Clinical Cases:
One child had abdominal pain due to retained food, with fever and a red face. Someone used Yangwei Tang (Nourish the Stomach Decoction), Zhike (Aurantii Fructus), Huanglian (Coptidis Rhizoma), and Shanzha (Crataegi Fructus), which instead worsened abdominal distension. There was afternoon fever, and pressing the abdomen caused no pain. This indicated Spleen deficiency injured by attacking/draining herbs. Using Liujunzi Tang (Six Gentlemen Decoction), the child recovered after several doses.
One seven-year-old child had fever and palpitations with fright. After using phlegm-resolving drugs, convulsions and aversion to cold developed, along with expectoration, wheezing, cough, abdominal pain, and poor appetite. After using Baolong Wan (Embracing Dragon Pill), the stool resembled dysentery, with alternating chills and fever, resembling wind syndromes. I considered this a further damage to Spleen Qi. Treating with Sijunzi Tang (Four Gentlemen Decoction) with a small addition of Shengma (Cimicifugae Rhizoma) and Chai Hu (Bupleuri Radix), the child recovered after more than a month.
One child had a distended and painful abdomen, diarrhea immediately after eating, and inverted coldness of the hands and feet. This was deficiency-cold of Spleen Qi. First, Renzhi Lizhong Wan (Ginseng Regulate the Middle Pill) was used, followed by Liujunzi Tang (Six Gentlemen Decoction), leading to recovery.
One nine-year-old child frequently suffered from abdominal pain. In winter, after eating raw/cold foods, the abdominal pain persisted, and taking Lizhong Wan (Regulate the Middle Pill) type formulas was effective. At sixteen years old, after early marriage in early autumn, abdominal pain recurred. The lips and face were dark, and the nails were cyanotic. My late father used Bawei Wan (Eight-Ingredient Pill) to tonify Fire (Mingmen), and the condition resolved quickly; after taking about four liang, the pain did not recur. At twenty years old, external pathogen-induced pain recurred. Taking the previous pill was ineffective, so Fuzi Lizhong Tang (Aconite Regulate the Middle Decoction) was taken to stop the pain, followed by stabilization with Bawei Wan (Eight-Ingredient Pill).
One child had abdominal pain with tongue protrusion, drooling, thirst, preference for cold drinks, and constipation. Qingliang Yin (Cooling Drink) was used to purge, resulting in immediate relief. I stated: Children's Yuan Qi (Original Qi) is prone to becoming deficient or excessive. Once the disease trend slightly improves, no further medication is needed. Disbelieving this, the parent self-administered one dose of Sanhuang Wan (Three Yellows Pill), which indeed caused vomiting, diarrhea, and convulsions. I used Baizhu San (Atractylodes Macrocephala Powder) added with Goutenggou (Uncariae Ramulus cum Uncis) to tonify the Spleen and calm the Liver, leading to recovery.
