调胃承气汤：治疗太阳阳明合病。症状表现为不恶寒，反而怕热，大便秘结，每日下午申时（15:00-17:00）出现潮热。（凡是阳明病有两种证型：在经者应当解肌，入腑者应当攻下。）
组成：大黄、芒硝、甘草（各等分）。
制法与用法：将药材切碎。每次使用一两至二钱，根据患儿年龄大小，加水煎煮，斟酌后服用。
四顺清凉饮：治疗成人及小儿血脉壅滞实证，脏腑生热。症状表现为面红、烦躁口渴、睡眠不安、大便秘结。
组成：大黄、当归、芍药、甘草（各等分）。
制法与用法：将药材切碎。根据患儿年龄大小，每次服用一两至二钱，加水煎服。
小儿属寒的病症，有外感、内伤、症变虚寒三种情况，三者不同，治疗方法也各异。
假如是内伤，必定是因为脾土虚寒，或者先天禀赋不足，或者护理不当，或者哺乳没有节制，导致食物不能运化，而出现清冷性质的呕吐和腹泻。只要观察其面色萎黄，四肢发凉，精神疲倦，脉象沉而无力，安静且不口渴，这属于阳虚生寒。适宜用五君子煎，以理中汤为主方。或者是能够进食的患儿，因过量食用生冷食物，而出现上述各种症状的，也用理中汤为主方。至于症变虚寒，则是由于元气素来虚弱，五脏亏损，或者因为寒凉药物克伐，导致阳气受伤，而出现面色青紫、嘴唇暗哑、呕吐腹泻且手足并冷，这属于脾土虚寒，用干姜理中汤为主方。如果面色苍白，呕吐腹泻伴腹痛，口鼻呼出气体寒冷，这属于寒水侮土（肾寒犯脾），用益黄散为主方。如果更兼有呃逆，手足指端发冷，用六君子汤加炮姜、肉桂。如果无效，紧急加入附子。
其次，有的因为病后体虚，或者因为呕吐腹泻，或者因为误用药饵，或者感受风寒，而导致气息微弱、精神倦怠、昏睡且眼睛半睁（露睛）、痰鸣气促、惊跳抽搐，像俗称为“慢惊风”的情况。这属于脾肾虚寒的候证，适宜温补。详见《辨惊风之误论》。
再其次，则是脾肾虚寒非常严重，导致呕吐腹泻不止，适宜用附子理阴煎，或者六味回阳饮，根据患儿年龄大小给予服用。如果只是泄泻不止，适宜用胃关煎为主方。
但是，吐泻的病症，也有偶尔属于热证的，但应当以手足寒温、脉象迟数、面色青赤、口渴与否作为辨别依据。至于外感寒邪，则病位在表，适宜详细参考表证论述，这里不再赘述。
此外，又有初生婴儿，在百日之内，感觉口冷腹痛，身上起鸡皮疙瘩，时常发生战栗，屈曲双腿握紧拳头，昼夜啼哭不停，或者牙关紧闭张不开口的，名叫胎寒。或者出生后昏昏欲睡，偶尔吐出白色奶瓣或大便色白，如果不尽早治疗，心会变成虚寒败症。适宜用冲和饮、当归散，配合水和煨姜煎服，使其轻微腹泻。腹泻开始后，改用匀气散调理补益。腹泻停止、气息均匀、神志安宁、疼痛定止、手足舒展后，再用参苓白术散来养胃气，用白芍药汤去除寒湿。乳母应当节制生冷冰冻的饮食，这样才容易痊愈。
又有一种情况是手足稍冷，唇面微青，额头出汗，不顾吃奶进食，到了夜晚啼哭多，夜间重白天轻，腹痛肠鸣，排泄清水样便，间或有不腹泻的，颇似前面的症状，但没有口冷寒战的表现，名叫脏寒。这也发生在百日之内。
这都是因为临产时胎儿在地道里停留时间稍久，冷气侵逼，或者用凉水搀热水给婴儿洗澡，或者断脐带短而又结缚不紧，被寒气所伤。这种情况适宜用白芍药汤，以及冲和饮，加盐炒小茴香、吴茱萸、生姜煎服，乳母同时服用。
还有胃中虚冷，面色苍白，腹痛不想吃东西的，用益黄散为主方。如果不腹泻，用调中丸为主方。
大抵小儿病症，虚寒的居多。凡是一见到面色青白，四肢冰冷，精神疲乏，脉象沉而无力，蜷缩而卧，吃得少且不口渴，声音迟缓的，都是虚寒的候证。急需温补。从事儿科的医生，不要拘泥于世俗见解，错误地认为小儿是纯阳之体多热，不敢温补，从而导致很多害人的事情。应该深深以此为戒。
Tiaowei Chengqi Tang (Regulate the Stomach and Purge the Bowels Decoction): Treats Taiyang-Yangming combined disease. Symptoms include aversion to cold being absent, but rather aversion to heat, constipation of feces, and tidal fever occurring at Shen hour (15:00–17:00) daily. (Note: Yangming disease has two patterns: those in the meridians should be treated with muscle-releasing methods, while those entering the fu organs should be treated with purgative methods.)
Ingredients: Dahuang (Rhei Radix et Rhizoma), Mangxiao (Natrii Sulfas), Gancao (Glycyrrhizae Radix et Rhizoma) in equal parts.
Preparation and Administration: Cut the herbs into small pieces. Use 1–2 qian per dose, depending on the child's age. Decoct in water and administer after careful consideration.
Sishun Qingliang Yin (Four-Obedient Cooling Clearing Drink): Treats blood vessel congestion and excess patterns in adults and children, and heat generated in the zang-fu organs. Symptoms include red face, irritability, thirst, restless sleep, and constipation.
Ingredients: Dahuang (Rhei Radix et Rhizoma), Danggui (Angelicae Sinensis Radix), Shaoyao (Paeoniae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) in equal parts.
Preparation and Administration: Cut the herbs into small pieces. Use 1–2 qian per dose based on the child's age. Decoct in water and administer.
Pediatric conditions classified as cold involve three categories: external contraction, internal injury, and transformation into deficiency-cold. These three differ, and their treatment methods vary.
If it is internal injury, it is necessarily due to deficiency-cold of the Spleen Earth, or insufficient congenital endowment, or improper nursing care, or irregular breastfeeding, leading to failure of food digestion and transformation. This manifests as vomiting and diarrhea of a clear-cold nature. Observe if the complexion is sallow, limbs are cool, spirit is fatigued, pulse is deep and forceless, the patient is quiet, and there is no thirst. This belongs to yang deficiency generating cold. It is suitable to use Wu Junzi Jian (Five Gentlemen Decoction), with Lizhong Tang (Regulate the Middle Decoction) as the principal formula. Alternatively, for children who can eat but have overconsumed raw and cold foods, presenting with the aforementioned symptoms, Lizhong Tang (Regulate the Middle Decoction) is also used as the principal formula. Regarding transformation into deficiency-cold, this arises from innate deficiency of yuan qi (primordial qi), damage to the five zang organs, or injury to yang qi due to harsh cold-purging medications. Symptoms include bluish-green complexion, dark lips, vomiting and diarrhea with cold hands and feet. This belongs to deficiency-cold of Spleen Earth, treated with Ganjiang Lizhong Tang (Dried Ginger Regulate the Middle Decoction). If the complexion is pale, accompanied by vomiting, diarrhea, abdominal pain, and cold breath from mouth and nose, this belongs to Cold Water insulting Earth (Kidney cold invading Spleen), treated with Yihuang San (Yellow Protector Powder). If accompanied by hiccups and cold fingertips, use Liujunzi Tang (Six Gentlemen Decoction) added with Paojiang (Fried Ginger) and Rougui (Cinnamon Bark). If ineffective, urgently add Fuzi (Aconiti Lateralis Radix Praeparata).
Secondly, some cases arise post-illness, or due to vomiting and diarrhea, or misuse of medicines, or exposure to wind-cold, resulting in faint qi, sluggish spirit, drowsiness with eyes half-open (exposed pupils), phlegm rattle, rapid breathing, startle jumps, and convulsions, commonly known as "Slow Convulsion" (Man Jing Feng). This belongs to the pattern of Spleen-Kidney deficiency-cold, suitable for warming and tonifying. See "Discussion on Errors in Treating Convulsions" for details.
Thirdly, when Spleen-Kidney deficiency-cold is severe, causing unceasing vomiting and diarrhea, use Fuzi Liyin Jian (Aconite Nourishing Yin Decoction) or Liuwei Huiyang Yin (Six-Ingredient Returning Yang Drink), dosed according to the child's age. If only unceasing diarrhea occurs, weigu Guan Jian (Stomach Gate Decoction) is appropriate as the principal formula.
However, vomiting and diarrhea can occasionally belong to heat patterns. Differentiation should be made based on the temperature of hands and feet, the speed of the pulse (slow or rapid), the color of the complexion (bluish-green or red), and the presence or absence of thirst. As for external contraction of cold pathogens, the disease is at the exterior level; refer to the discussion on exterior patterns for details, which will not be repeated here.
Furthermore, newborn infants within one hundred days may experience cold mouth and abdomen, cold gooseflesh on the body, frequent shivering, flexed legs with clenched fists, ceaseless crying day and night, or trismus (lockjaw). This is named Taihan (Fetal Cold). Or, after birth, they may be lethargic and sleepy, occasionally spitting up white curds or having white stools. If not treated early, the Heart may develop deficiency-cold and failing patterns. It is suitable to use Chonghe Yin (Harmonizing Drink) and Danggui San (Angelica Powder), decocted with water and Wei Jiang (Baked Ginger), to induce slight diarrhea. Once diarrhea begins, switch to Yunqi San (Qi-Smoothing Powder) for regulation and tonification. When diarrhea stops, qi becomes even, spirit is calm, pain subsides, and limbs extend, subsequently use Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) to nourish Stomach qi, and Baishaoyao Tang (White Peony Decoction) to dispel cold-dampness. The nursing mother should avoid raw, cold, and frozen foods and drinks, so recovery is easier.
Another condition involves slightly cold hands and feet, slightly bluish-green lips and face, sweating on the forehead, refusal to nurse or eat, increased crying at night (worse at night, lighter during the day), abdominal pain, borborygmus, and watery diarrhea, sometimes without diarrhea. This resembles the previous symptoms but lacks cold mouth and shivering. This is named Zanghan (Visceral Cold), also occurring within the first hundred days.
This is caused by prolonged labor in the birth canal allowing cold qi to invade, washing the infant with cold water mixed with hot water, or umbilical cord ligation being too short and loose, injuring the infant with cold qi. In such cases, use Baishaoyao Tang (White Peony Decoction) and Chonghe Yin (Harmonizing Drink), added with salt-fried Huixiang (Fennel Fruit) and Zhuyu (Evodia Fruit), decocted with Shengjiang (Fresh Ginger), administered to both infant and nursing mother.
Additionally, for deficiency-cold in the Stomach, pale complexion, abdominal pain, and loss of appetite, Yihuang San (Yellow Protector Powder) is the principal formula. If there is no diarrhea, Tiaozhong Wan (Regulate the Middle Pill) is used.
Generally, pediatric diseases are mostly deficiency-cold. Whenever one sees a bluish-white complexion, cold limbs, mental fatigue, deep and forceless pulse, curled-up posture, poor appetite without thirst, and slow speech, these are all signs of deficiency-cold. Urgent warming and tonification are required. Pediatric practitioners must not adhere to vulgar views that erroneously consider children to have pure-yang constitutions prone to heat, thereby fearing warming and tonification, which leads to harm. This should be deeply guarded against.
