受湿肿（脚手面目虚浮） 食毒瓦斯肿（腹肚肾蛊胀急） 伤寒虚气入腹肿 泻痢虚气入腹肿 此
四种所患病不相同，皆由虚得之。受湿，谓脾胃受湿冷，久不克化，气浮，四肢头面皆肿。食毒瓦斯，由脾
胃伤之冷积，毒瓦斯停留胃脘，致虚入腹作肿。伤寒由下之太早，乘虚入腹作肿。泻痢之久，脾气亦虚，是以
致肿。以上宜平调胃气，补脏充实，方可去肿，先服四味理中，无减半干姜，加白术、桑白皮同煎。伤
寒虚肿，加枳实。作喘，加淡豆豉。泻痢虚肿，服正气调胃。胃气既壮，以救生丹利之，其肿即退。再调补
脏腑，用观音散，即平复矣。
气虚肿（亦名气蛊）、血虚肿（亦名血蛊）、荣卫俱虚肿（亦名气血蛊），小儿所患，肿胀一门最为
要急，前人少有究竟，然肿胀之作，皆由荣卫不顺，脏腑怯弱，壅滞三焦，流注百脉，表里俱虚，邪正相乱，
所以致受。四大浮盛，腹肚膨满，多由食毒得之，饮食得之，症伤得之，饥饱得之，积久不化，故成斯病。
病由虚得，或则妄乱通下，因虚致虚，根不得去，疾加已盛，是谓坏证危候，智者怯而为辞，庸者暴以攻击，
二医不同，诚属难治。智者商之，良者审之，疑者塌之（疑其病盛不可利只与塌其气），明者调之
（正荣卫也），先调荣卫之顺，次服分气饮子以散其滞，斯病去矣。

【受湿肿】（表现为手脚和面部虚浮肿胀）
【食毒瓦斯肿】（表现为腹部、肾脏及蛊胀急迫）
【伤寒】导致的虚气入腹而肿
【泻痢】导致的虚气入腹而肿
这四种疾病所患不同，但都是由“虚”引起的。
所谓“受湿”，是指脾胃受到湿冷之邪侵袭，长期无法运化消化，导致气机浮越，四肢和头面都出现肿胀。
所谓“食毒瓦斯”，是由于脾胃受损，寒凉积滞停留于胃脘，致使虚邪入腹形成肿胀。
【伤寒】是因为攻下过早，邪气乘虚入腹形成肿胀。
【泻痢】日久，脾气也虚弱，因此导致肿胀。
以上情况适宜平调胃气，补益脏腑使其充实，才能消除肿胀。先服用四味理中汤（去掉减半的干姜，加入白术、桑白皮同煎）。如果是伤寒引起的虚肿，加入枳实。如果伴有气喘，加入淡豆豉。如果是泻痢引起的虚肿，服用正气调胃散。胃气既已强壮，再用救生丹利水消肿，其肿胀即可消退。随后调理补益脏腑，使用观音散，身体就能完全恢复。
【气虚肿】（又名气蛊）、【血虚肿】（又名血蛊）、【荣卫】俱虚肿（又名气血蛊），小儿所患的肿胀一类疾病最为紧急重要。前人对此少有深入研究，然而肿胀的发生，皆因荣卫不顺，脏腑怯弱，壅滞三焦，流注百脉，表里俱虚，邪正相乱，所以导致发病。
全身四大部位浮肿盛大，腹部膨满，多由食毒引起，或由饮食不当、病症损伤、饥饱不均引起，积久不化，故成此病。
疾病由虚所致，若妄用通下之法，会因虚致虚，病根不能去除，病情加重且旺盛，这称为坏证危候。明智的医生谨慎对待，庸医则猛烈攻击，两位医生的治法不同，确实难以治疗。明智者商议，良医者审慎，疑虑者采取安抚策略（怀疑病势盛不可利水，只给予顺气的方法），明理者调和（即调和荣卫）。先调和荣卫使之顺畅，其次服用分气饮子以消散壅滞，这样病就好了。
荣卫饮子：用于调补婴幼儿气血俱虚、荣卫不顺，导致四肢、头面、手足均浮肿甚至气喘急促的情况，均适宜服用。
川当归、熟干地黄（洗净）、人参、白茯苓、川芎、白术、甘草（炙）、白芍药、枳壳（炒，另处理）、黄芪（蜜炙）、陈皮。
以上药材等量，切碎。每次服用二钱匕，用水一小盏，煎至半盏，去渣温服，不限时间。
议论说：荣，是血液在脉中温和流行；卫，是气在络中顺调和谐。因此荣行于脉中，卫行于脉外，阴阳相安，循环不止，从幼年到长大，不离呼吸，没有少许滞碍，脉象才调和，气机才顺畅。呼吸之间，脉搏应与呼吸相应，若气有违逆滞涩，流注经络，隐伏脏腑，百病皆由此开始。此方效果最好，虽然幼儿幼小，也可以服用，以壮其根本，使血荣气卫，顺遂和谐，腑寒脏虚得以温壮，盈亏自然平衡，怯弱自然端正，阴阳调均，气脉充实，还有什么疾病呢？
分气饮子：调理小儿肿胀伴气喘，气短促急，坐卧不安，四肢浮肿，饮食呕吐逆反，精神困倦喜睡。
五味子、桔梗、白茯苓、甘草（炙）、陈橘皮、桑白皮、草果（去壳）、大腹皮、白术、枳壳（去瓤、切片，炒）、川当归、紫苏、苏子、半夏曲。
以上等量，切碎。每次服用两大钱匕，用水一小盏，生姜二小片，枣子半个，煎至半盏，去渣温服，不限时间。
兼服八味理中丸。以上情况，适宜用救生丹通利。
议论说：清浊不分混，邪正不相干扰，上焦得到清凉，下部受到温暖。气滞则升降减少，血虚则多流注。虽然是乳婴儿，呼吸一息，脉搏到来，徐徐应指，不违背节律的，也与成人一样流行，只是随着体型大小而深浅不同而已。如果留滞，脉搏迟或数，就会因太过或不及而产生疾病。善于治疗的人，郁结则分散它，逆乱则理顺它，停聚则利导它，滞塞则降泄它。调理的方法，首先宜顺气。大体上婴幼儿气顺就容易治疗。此方名为分气，与分水谷的区别不同，明理者请仔细考察。
大效神功救生丹：治疗小儿气虚喘息，四肢浮肿，肚腹胀急，冲满胁肋，忽冷忽热，或腹泻或便秘，皆因久停虚积，荣卫不顺，适宜用此方推去恶毒之气。
雄黄（单独研磨）、朱砂（各一分）、巴豆（二十一粒，去壳）、干姜（二钱）。
以上药材，用米醋一盏，将巴豆、干姜一起煮至醋干，去掉干姜不用，取出巴豆去油，与雄黄、朱砂研匀，用雪糕（此处疑为胶类或糊状辅料，原文作雪糕，保留原意或指代某种粘合剂）搜和制成丸药，如麻子大。
每岁服用三丸，并用酒浸泡赤芍药，取少许送服。
[Edema due to Dampness] (manifesting as flaccid swelling of the hands, feet, face, and eyes)
[Edema due to Food Toxicity and Gas] (manifesting as urgent distension and swelling of the abdomen, kidneys, and Gu-type abdominal masses)
[Shanghan] (Cold Damage) causing edema from deficiency qi entering the abdomen.
[Dysentery] causing edema from deficiency qi entering the abdomen.
Although these four conditions differ in their specific pathologies, they all arise from Deficiency (Xu).
"Edema due to Dampness" refers to the Spleen and Stomach being invaded by cold-dampness, leading to long-term failure in transformation and transportation. This causes Qi to float upward, resulting in swelling of the limbs, head, and face.
"Edema due to Food Toxicity and Gas" occurs when the Spleen and Stomach are damaged by cold accumulation; toxic gas remains in the stomach cavity, allowing deficiency pathogens to enter the abdomen and cause swelling.
In [Shanghan], premature purgation allows pathogens to enter the abdomen via deficiency, causing swelling.
Prolonged [Dysentery] weakens Spleen Qi, thereby leading to swelling.
For the above conditions, it is appropriate to harmonize Stomach Qi and tonify the Zang organs to make them full, so that the swelling can be resolved. First, administer Siwei Lizhong Tang (Four-Ingredient Lizhong Decoction), modifying it by removing half the amount of Ganjiang (Dried Ginger), and adding Baizhu (Atractylodis Rhizoma) and Sangbaipi (Morus Albae Cortex) for decoction together. If the edema is due to Shanghan, add Zhishi (Immature Bitter Orange). If accompanied by wheezing, add Dansh douchi (Prepared Soybean). If the edema is due to dysentery, administer Zhengqi Tiaowei San (Zhengqi Harmonizing Stomach Powder). Once Stomach Qi is strengthened, use Jiusheng Dan (Life-Saving Pill) to promote diuresis, at which point the swelling will subside. Subsequently, regulate and tonify the Zang-Fu organs using Guanyin San (Guanyin Powder), and the patient will fully recover.
[Qi Deficiency Edema] (also known as Qi Gu), [Blood Deficiency Edema] (also known as Blood Gu), and [Ying-Wei] Dual Deficiency Edema (also known as Qi-Blood Gu): Among the diseases of swelling in children, this category is the most critical. Predecessors have rarely thoroughly investigated it. However, the formation of swelling is always due to disharmony of Ying and Wei, weakness of the Zang-Fu organs, stagnation in the Triple Burner, flow into the hundred vessels, deficiency in both interior and exterior, and confusion between pathogenic factors and healthy Qi. Thus, susceptibility arises.
Swelling of the four major body parts and abdominal distension are mostly caused by food toxicity, improper diet, pathological injury, or irregular eating habits. Accumulation over time without digestion leads to this disease.
Since the disease originates from deficiency, reckless use of purgatives exacerbates deficiency, making it difficult to remove the root cause. The condition worsens, becoming a "bad syndrome" with critical signs. Wise physicians act cautiously, while mediocre physicians attack aggressively. These differing approaches make treatment difficult. Wise physicians deliberate, good physicians examine carefully, those with doubts employ soothing methods (suspecting the pathogen is strong and avoiding purgation, instead focusing on regulating Qi), and enlightened physicians harmonize (specifically harmonizing Ying and Wei). First, harmonize Ying and Wei to ensure smooth flow, then administer Fenqi Yinzi (Fenqi Decoction) to dissipate stagnation, and the disease will resolve.
Rongwei Yinzi: Used to tonify infants and children with dual Qi and Blood deficiency and disharmonious Ying-Wei, manifesting as generalized edema of the limbs, head, and face, extending to the hands and feet, up to wheezing and urgency. It is suitable for such cases.
Chuan Danggui (Angelicae Sinensis Radix), Shu Dihuang (Rehmanniae Radix Praeparata), Renshen (Ginseng Radix et Rhizoma), Baifuling (Poria), Chuanxiong (Ligustici Chuanxiong Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Gancao (Licorice Radix et Rhizoma, honey-fried), Baishaoyao (Paeoniae Radix Alba), Zhike (Aurantii Fructus Immaturus, stir-fried, processed separately), Huangqi (Astragali Radix, honey-fried), Chenpi (Citri Reticulatae Pericarpium).
Equal parts of the above ingredients, coarsely crushed. Take two qianbi per dose, decoct with one small lamp of water until half remains, strain, and take orally at any time.
Discussion: Ying refers to blood circulating warmly within the vessels; Wei refers to Qi flowing smoothly and harmoniously within the collaterals. Therefore, Ying circulates inside the vessels, and Wei circulates outside. Yin and Yang remain at peace, cycling endlessly. From childhood to adulthood, this process relies on respiration, without any obstruction, ensuring harmonious pulses and smooth Qi. Between breaths, the pulse should correspond to the respiratory rate. If Qi encounters resistance or stagnation, it flows into the collaterals and hides in the Zang-Fu organs, initiating myriad diseases. This formula is excellent; even for young children, it can be administered to strengthen the root, ensuring that Blood nourishes and Wei protects, achieving smoothness and harmony. Cold in the Fu organs and deficiency in the Zang organs will be warmed and strengthened. Excess and deficiency will naturally balance, weakness will naturally correct, Yin and Yang will harmonize, and Qi and pulses will become substantial. What disease would remain?
Fenqi Yinzi: Regulates pediatric swelling with wheezing, shortness of breath and urgency, restlessness in sitting and lying, generalized edema of the four limbs, vomiting and reflux of food, mental fatigue, and excessive sleepiness.
Wuweizi (Schisandrae Chinensis Fructus), Jiegeng (Platycodonis Radix), Baifuling (Poria), Gancao (Licorice Radix et Rhizoma, honey-fried), Chenjupi (Citri Reticulatae Pericarpium), Sangbaipi (Morus Albae Cortex), Caoguo (Tsaoko Fructus, husked), Dafupi (Arecae Pericarpium), Baizhu (Atractylodis Macrocephalae Rhizoma), Zhike (Aurantii Fructus Immaturus, pith removed, sliced, stir-fried), Chuan Danggui (Angelicae Sinensis Radix), Zisu (Perillae Folium), Suzi (Perillae Fructus), Banxiaqu (Pinelliae Fermentatum).
Equal parts, coarsely crushed. Take two large qianbi per dose, decoct with one small lamp of water, two small slices of fresh ginger, and half a jujube, until half remains. Strain and take orally at any time.
Concurrently decoct and take Bawei Lizhong Wan (Eight-Ingredient Lizhong Pill). For the above conditions, Jiusheng Dan (Life-Saving Pill) is suitable for promoting unblocking and purging.
Discussion: When clear and turbid do not mix, and pathogenic and healthy factors do not interfere, the Upper Jiao receives coolness, and the Lower Jiao receives warmth. Qi stagnation reduces ascending and descending movements; Blood deficiency leads to excessive flow. Although for infants, during each breath, the pulse arrives slowly and responds to the finger without violating rhythm, similar to adults, it merely varies in depth according to size. If stagnation occurs, the pulse becomes slow or rapid, leading to disease due to excess or insufficiency. Skilled healers disperse stagnation, smooth rebellion, promote retention, and descend blockages. The method of regulation first prioritizes smoothing Qi. Generally, if an infant's Qi is smooth, the condition is easy to treat. This formula, named "Separating Qi," differs from formulas that separate water and grain. Enlightened practitioners should observe this carefully.
Da Xiao Shen Gong Jiusheng Dan: Treats pediatric Qi deficiency with wheezing, generalized edema of the four limbs, abdominal distension and urgency, fullness rushing to the hypochondrium, alternating fever and chills, diarrhea or constipation. All result from long-standing accumulation of deficiency, disharmony of Ying and Wei. This formula is suitable to push out toxic Qi.
