陈紫山曰∶胃为水谷之海，其精英流布，以养五脏，糟粕传送，以归大肠。内由生冷乳食所伤，外因风寒暑
湿所感，饥饱失时，脾不能消，冷热相干，遂成泄泻。若脾胃气和，以消水谷，水谷既分，安有此症也。古人云∶
脾虚则吐，胃虚则泻，脾胃俱虚则吐泻并作。若久泻不止，元气必脱，宜大补之。
治法∶推三关，心经，清肾水，补脾胃，掐左端正，倒推大肠，外劳宫，分阴阳，运八卦，揉脐及龟尾，掐
肚角两旁，掐承山。寒症加黄蜂出洞，三关，六腑，斗肘，热症加捞明月，打马过天河，三关，六腑，揉斗肘。
陈紫山曰∶霍乱者，挥霍撩乱也。外有所感，内有所伤，阴阳垂膈，上吐下痢，肠扰闷痛是也。
治法∶推三关，肺经，八卦，补脾土，大肠，四横纹，分阴阳，二人上马，苍龙摆尾。又将独头蒜一个，捣碎，
将烧纸隔七层敷脐。若起泡，用鸡蛋清涂之，即愈。
陈紫山曰∶小儿腹痛，有寒有热，有食积 瘕，偏坠寒疝，及疣虫动痛。诸痛不同，其名亦异，故不可一概而
论。又曰∶热腹痛者，乃时痛时止也，暑月最多。
治法∶推三关，六腑，推脾土，分阴阳（阴重阳轻），黄蜂出洞，
四横纹。
涂蔚生曰∶黄蜂出洞，乃治疗寒症之大热法。以之治热症腹痛，恐系有误，用者慎之。采用清天河水
等法可也。
陈紫山曰∶寒腹痛者，常痛而无增减也。
治法∶推三关，运五经纹，二扇门，一窝风，按弦搓摩，运八卦，揉脐及龟尾。
陈紫山曰∶气滞食积而痛者，卒痛便秘，心胸高起，手不可按者是也。
治法∶推三关，分阴阳，推脾土，揉脐及龟尾，掐威灵。若腹内膨胀，推大肠。
陈紫山曰∶冷气心痛者，手足厥逆，遍身冷汗，甚则手之甲青黑，脉沉细微是也。
治法∶推三关，运八卦，分阴阳（阴重阳轻），补肾，二扇门，黄蜂出洞。鸠尾前后重揉，葱姜推之发汗。
涂蔚生曰∶鸠尾在胸前两歧骨下一寸。曰鸠尾者，言其骨垂下如鸠尾形也。
Chen Zishan stated: The Stomach is the sea of water and grain. Its essence circulates to nourish the five zang organs, while its dregs are transmitted to the Large Intestine for excretion. Internally, injury may be caused by raw, cold, or milk/food substances; externally, it may be affected by wind, cold, summer-heat, and dampness. Irregular eating habits lead to the Spleen's inability to digest and transform. When cold and heat pathogens interfere with each other, diarrhea (Xie Xie) results. If the Qi of the Spleen and Stomach is harmonious, allowing for proper digestion of food and drink, and if the clear and turbid parts separate correctly, how could such a condition arise? The ancients said: Spleen deficiency leads to vomiting; Stomach deficiency leads to diarrhea; when both Spleen and Stomach are deficient, vomiting and diarrhea occur simultaneously. If chronic diarrhea persists without stopping, the primordial Qi must be depleted, and a major tonification method should be employed.
Treatment methods: Push San Guan (Three Gates), Clear Xin Jing (Heart Meridian), Nourish Shen Shui (Kidney Water), Tonify Pi Wei (Spleen and Stomach), Pinch Zuo Duan Zheng (Left End Point), Reverse-push Da Chang (Large Intestine), Rub Wai Lao Gong (Outer Labor Palace), Divide Yin and Yang, Move Ba Gua (Eight Trigrams), Rub Qi (Navel) and Gui Wei (Turtle Tail), Pinch Liang Ce Du Jiao (Both sides of the Belly Corner), Pinch Cheng Shan. For cold syndromes, add Huang Feng Chu Dong (Yellow Bee Exits the Cave), push San Guan, push Liu Fu (Six Limbs), Dou Zhou (Elbow Bowl). For heat syndromes, add Lao Ming Yue (Scooping the Bright Moon), Da Ma Guo Tian He (Horse Crossing the Heavenly River), push San Guan, push Liu Fu, rub Dou Zhou.
Chen Zishan stated: Huo Luan (Cholera-like disorder) refers to sudden onset and chaotic symptoms. External pathogenic invasion combined with internal dietary injury causes Yin and Yang to block at the diaphragm, resulting in upper vomiting and lower dysentery, with intestinal disturbance and stifling pain.
Treatment methods: Push San Guan, Clear Fei Jing (Lung Meridian), Move Ba Gua, Tonify Pi Tu (Spleen Earth), push Da Chang, push Si Heng Wen (Four Horizontal Lines), Divide Yin and Yang, push Er Ren Shang Ma (Two People Ascend to Horse), Cang Long Bai Wei (Green Dragon Swings Tail). Additionally, take one bulb of single-headed garlic, crush it, place it on the navel covered by seven layers of burnt paper. If blisters form, apply egg white to the area, which will lead to recovery.
Chen Zishan stated: Pediatric abdominal pain can be due to cold or heat, food stagnation, jia masses (abdominal lumps), hernia with cold, or ascaris movement causing pain. Since various pains differ in presentation and name, they cannot be generalized. He further stated: Heat-type abdominal pain is characterized by intermittent pain and is most common during summer months.
Treatment methods: Push San Guan, push Liu Fu, push Pi Tu, Divide Yin and Yang (heavy on Yin, light on Yang), Huang Feng Chu Dong, push Si Heng Wen.
Tu Weisheng stated: Huang Feng Chu Dong is a strongly heating method used for treating cold syndromes. Using it for heat-type abdominal pain is likely erroneous; practitioners should exercise caution. Methods such as Qing Tian He Shui (Clearing the Heavenly River Water) should be adopted instead.
Chen Zishan stated: Cold-type abdominal pain is characterized by constant pain without fluctuation.
Treatment methods: Push San Guan, move Wu Jing Wen (Five Meridian Lines), push Er Men Shan (Two Doors Gate), push Yi Wo Feng (One Nest Wind), An Xian Cuo Mo (Press Strings and Rub), move Ba Gua, rub Qi and Gui Wei.
Chen Zishan stated: Pain caused by qi stagnation and food stagnation presents as sudden severe pain, constipation, elevation of the chest and heart region, and tenderness where the abdomen cannot be touched or pressed.
Treatment methods: Push San Guan, Divide Yin and Yang, push Pi Tu, rub Qi and Gui Wei, pinching Wei Ling. If abdominal distension occurs, push Da Chang.
Chen Zishan stated: Cold qi attacking the Heart manifests as cold limbs and reversal, profuse cold sweat over the body, and in severe cases, cyanosis of the fingernails, with a deep, fine, and weak pulse.
Treatment methods: Push San Guan, move Ba Gua, Divide Yin and Yang (heavy on Yin, light on Yang), Tonify Kidney, push Er Men Shan, Huang Feng Chu Dong. Heavily rub Ji Wei (Jiwei point) front and back, use ginger and scallion massage to induce sweating.
Tu Weisheng stated: Jiwei is located one cun below the bifurcation of the xiphoid process. It is named "Jiwei" because the bone hangs down like the tail of a turtledove.
