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。
陈紫山说：胃是容纳水谷的仓库，其中精微物质流布全身，用以滋养五脏；糟粕则传送至大肠排出。如果内部因生冷乳食损伤，外部受风寒暑湿侵袭，加上饥饱无常，导致脾脏无法运化消化，冷热邪气相互干扰，就会形成泄泻（腹泻）。如果脾胃之气调和，能够正常消化水谷，水谷精微与糟粕分离，怎么会出现这种病症呢？古人说：脾气虚弱会导致呕吐，胃气虚弱会导致腹泻，脾胃都虚弱时，呕吐和腹泻会同时发生。如果长期腹泻不止，元气必然耗脱，应当采用大补元气的方法治疗。
治疗方法：推三关穴，清心经，补肾水，补脾胃，掐左端正穴，倒推大肠经，揉外劳宫穴，分阴阳，运八卦，揉脐部和龟尾穴，掐肚角两旁，掐承山穴。如果是寒症，加用黄蜂出洞手法、推三关、推六腑、斗肘手法；如果是热症，加用捞明月手法、打马过天河手法、推三关、推六腑、揉斗肘。
陈紫山说：霍乱病，是指发病突然，挥霍撩乱。外部有邪气侵袭，内部有饮食损伤，阴阳之气阻隔于膈膜之间，表现为上吐下痢，肠道扰乱闷痛。
治疗方法：推三关穴，清肺经，运八卦，补脾土，推大肠，推四横纹，分阴阳，推二人上马穴，苍龙摆尾手法。另外取独头蒜一个，捣碎，用烧过的纸隔七层敷在脐部。如果起水泡，用鸡蛋清涂抹，即可痊愈。
陈紫山说：小儿腹痛，有寒证和热证，有食积、瘕聚（腹部结块）、偏坠寒疝（睾丸肿胀冷痛），以及蛔虫扰动疼痛。各种疼痛表现不同，名称也各异，所以不能一概而论。他又说：热性腹痛，特点是疼痛时作时止，在暑天最为多见。
治疗方法：推三关穴、推六腑、推脾土、分阴阳（阴分重，阳分轻）、黄蜂出洞手法、推四横纹。
涂蔚生说：黄蜂出洞手法，是治疗寒证的大热之法。用它来治疗热性腹痛，恐怕有误，使用者需谨慎。可以采用清天河水等清热手法。
治疗方法：推三关穴，运五经纹，推二扇门，推一窝风，按弦搓摩手法，运八卦，揉脐部和龟尾穴。
陈紫山说：因气滞和食积导致的疼痛，表现为突然剧痛、便秘、心胸部位高起、手不可触碰按压。
治疗方法：推三关穴，分阴阳，推脾土，揉脐部和龟尾穴，掐威灵穴。如果腹部胀满膨胀，推大肠经。
陈紫山说：冷气心痛，表现为手足厥冷逆乱，全身冷汗，严重时指甲青黑，脉象沉细微弱。
治疗方法：推三关穴，运八卦，分阴阳（阴分重，阳分轻），补肾经，推二扇门，黄蜂出洞手法。重揉鸠尾穴前后，用葱姜推拿以发汗。
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.
