覆盖肚脐以退黄的方法：参见“内科黄疸”章节。
小儿急黄证：取丝瓜，连皮带籽，烧至存性（炭化但保留药性），研磨成粉末。每次服用一钱，用米汤调服，连续服用数次即可痊愈。
小儿面色黄如金色，因食积停滞凝结于脾脏所致：用稻草煎煮浓汤饮用，多次服用有效。另一方法：取山间的薏苡仁根，洗净至极干净，煎汤服用，病可自愈。
治疗湿热引起的发黄：取生姜半斤、茵陈半斤，共同捣烂，用布包好，经常擦拭全身，其黄色自然消退。
上焦疼痛，部位在膈肌以上，属于胃脘痛。中焦疼痛，部位在中脘穴附近，是脾胃之间的疾病。下焦疼痛，部位在脐下，是肝肾之间的疾病。凡是按压后疼痛减轻的属于虚证，拒绝按压的属于实证。久病多属虚证，新发急病多属实证。进食后疼痛稍减的，属于虚证；腹胀满且畏惧饮食的，属于实证。疼痛缓慢而轻微，无法确定具体位置的，属于虚证；疼痛剧烈且坚硬，位置固定不移的，属于实证。
夹有寒邪的腹痛：面色或青或白，若寒冷严重，则面色暗淡，嘴唇、口角及指甲皆呈青色，喜欢热敷，这是脾气极度虚寒的表现。轻症使用当归、青化桂（肉桂的一种）、人参、土炒白术各一钱，木香、炙甘草各五分，大枣六枚，生姜三片，水煎后温服。寒邪严重者，使用六君子汤加入青化桂一钱，砂仁、白蔻仁、良姜各六分。如果是生冷瓜果蔬菜停滞积聚在中焦，导致腹痛、泄泻、呕吐恶心的，再加煨神曲一钱半，公丁香、木香屑各五分。泄泻不止的，再加去油肉豆蔻八分。
夹有热邪的腹痛：面红身壮热，四肢烦躁，手足心发热。使用四顺清凉饮。白芍二钱，当归、锦庄黄（大黄）各一钱，炙甘草五分，水煎后热服。如果大便通畅，只用白芍一根，重三钱，甘草一根，重二钱，用七层纸包裹，微湿后，用慢火煨熟，取出捣烂，煎汤服用。如果兼有寒象，加入肉桂五分尤为巧妙。后方名为芍药甘草汤，一切腹痛皆可治疗，唯独寒证适宜略加肉桂。
食积引起的疼痛：口中气息温热，面色黄或白，眼神无光彩，或者眼白部分较多，喜欢睡觉且厌恶饮食，大便酸臭。轻症，使用山楂肉二钱，广皮（陈皮）、半夏（姜炒）、茯苓各一钱，神曲（煨）、萝卜子（莱菔子）各一钱半，加厚朴（姜炒）、槟榔（炒）各七分，水煎服用数剂。重症则使用三仙丸，见“痢疾”章节。
Method for applying to the navel to treat jaundice: See "Internal Medicine Jaundice".
Pediatric acute jaundice: Take a loofah, including skin and seeds, burn it until carbonized but retaining medicinal properties (charcoalization), grind into powder. Take one qian per dose, mixed with rice water, administer continuously for several times until cured.
Pediatric jaundice with golden-yellow complexion, caused by food stagnation condensing in the Spleen: Decoct straw into a concentrated decoction and drink; multiple doses are effective. Another method: Obtain the root of Coix seed (Yiyiren) from mountains, wash extremely clean, decoct in water and take; the disease will heal spontaneously.
Treating yellowing caused by damp-heat: Take half a jin of fresh ginger and half a jin of Yinchen (Artemisiae Scopariae Herba), pound them together into a paste, wrap well in cloth, and frequently rub over the whole body; the yellow color will naturally recede.
Pain in the Upper Jiao is located above the diaphragm and constitutes epigastric pain. Pain in the Middle Jiao is located at the Zhongwan point area and indicates pathology between the Stomach and Spleen. Pain in the Lower Jiao is located below the umbilicus and indicates pathology between the Liver and Kidney. Generally, tenderness that improves with pressure indicates deficiency syndrome, while tenderness that worsens with pressure indicates excess syndrome. Chronic diseases are mostly deficiency, while acute/sudden diseases are mostly excess. Pain that decreases slightly after eating indicates deficiency; abdominal distension and aversion to food indicate excess. Pain that is slow and mild, with an indeterminate location, indicates deficiency; pain that is severe and hard, with a fixed location, indicates excess.
Abdominal pain with cold pathogen: The facial complexion may be cyanotic or pale; if the cold is severe, the complexion is dim, lips, mouth corners, and fingernails turn cyanotic, and there is a preference for hot compresses. This indicates extreme deficiency-cold of the Spleen Qi. For mild cases, use Danggui (Angelicae Sinensis Radix), Qinghuagui (Cinnamomi Cortex), Renshen (Ginseng Radix et Rhizoma), and Tu Chao Baizhu (Atractylodis Macrocephalae Rhizoma stir-fried with soil) each 1 qian, Muxiang (Aucklandiae Radix), and Zhi Gancao (Prepared Licorice Root) each 5 fen, 6 dates, and 3 slices of Shengjiang (Zingiberis Rhizoma Recens). Decoct in water and take warm. For severe cold, use Liujunzi Tang (Six Gentlemen Decoction) plus 1 qian of Qinghuagui, Sha Ren (Amomi Fructus), Baiko Ren (Cardamomi Albi Semen), and Liangjiang (Alpiniae Officinarum Rhizoma) each 6 fen. If raw, cold fruits and vegetables have accumulated in the Middle Jiao causing abdominal pain, diarrhea, vomiting, and nausea, add Wei Shenqu (Fermented Medicinal Leaven baked) 1.5 qian, Gong Dingxiang (Caryophylli Flos), and Muxiang Xie (Powdered Aucklandia) each 5 fen. If diarrhea persists, add Rou Doukou (Myristicae Semen) with oil removed, 8 fen.
Abdominal pain with heat pathogen: Red face, high fever, restlessness of the four limbs, and heat in the palms and soles. Use Sishun Qingliang Yin (Four-Oriented Cooling Decoction). Baishao (Paeoniae Radix Alba) 2 qian, Danggui (Angelicae Sinensis Radix), Jin Zhuang Huang (Rhei Radix et Rhizoma) each 1 qian, Zhi Gancao (Prepared Licorice Root) 5 fen. Decoct in water and take hot. If bowel movements are normal, use only one piece of Baishao weighing 3 qian and one piece of Gancao weighing 2 qian. Wrap in seven layers of paper, moisten slightly, and roast slowly over low fire until cooked. Remove, pound into a paste, decoct in water, and take. If cold signs are present, adding 5 fen of Rougui (Cinnamomi Cortex) is particularly excellent. The latter formula is named Shaoyao Gancao Tang (Peony and Licorice Decoction), which treats all types of abdominal pain; however, for cold patterns, it is suitable to add a slight amount of Rougui.
Pain due to food stagnation: Warm breath from the mouth, yellow or pale complexion, dull eyes or excessive sclera visibility, preference for sleep and aversion to food, sour-smelling stool. For mild cases, use Shanzha Rou (Crataegi Fructus flesh) 2 qian, Guangpi (Citri Reticulatae Pericarpium), Banxia Jiang Chao (Pinelliae Rhizoma stir-fried with ginger juice), and Fuling (Poria) each 1 qian, Wei Shenqu (Baked Fermented Medicinal Leaven), Luobo Zi (Radish Seed) each 1.5 qian, add Houpo Jiang Chao (Magnoliae Officinalis Bark stir-fried with ginger juice) and Binglang Chao (Areca Seed stir-fried) each 7 fen. Decoct in water and take for several doses. For severe cases, use Sanxian Wan (Three Immortals Pill), see "Dysentery".
