小儿阴黄，乃脾湿肾寒两虚而成，此最为危候，若用温脾之黄，古法主理中汤加茵陈蒿。
若用温肾之黄，古法主茵陈四逆汤（如制附子、北干姜、茵陈蒿、炙甘草等味）。
〔真按〕阴黄证全非湿热，总由气血之败，盖气不生血，所以血败，血不华色，所以色败。凡病黄而绝无阳
证阳脉者，便是阴黄，或因大病之后，或因脾胃久亏，故脾土之色，自现于外，必见喜静恶动，喜暗畏明，神思
困倦，言语轻微，畏寒少食，四肢无力，或大便不实，小便如膏，皆是阳虚之重候，与阳黄反如冰炭。方用炒党参
钱半，生野术二钱，白扁豆一钱，化橘红五分，炮姜炭五分，白归身八分，炙甘草六分，水一杯半，煎七分服。
痰本水谷所化，其所化何以变为痰，盖所化之津液不能四布，留于胸中，变为浊液，故书多责于脾。谓脾气
清澈则痰不生，脾气浊混则痰始成。小儿之痰，多由乳食无节，或过食浓味，脾胃不能运化而生。若阴气素盛，则
化为饮；阳气素盛，则化为痰。书又言痰之标在脾，痰之本在肾。盖以脾属后天，肾属先天。凡后天之病，未有
不根先天之所致也。表痰宜散，热痰宜吐，实痰宜降，寒痰宜燥，痰之变幻万端，然在小儿只分燥湿两种。此治小
儿痰证最简便最切要之良法也。
小儿燥痰，是痰因火而动。火盛则痰多稠粘，气逆喘咳，夜卧不宁，面赤口干，小便黄赤，轻者古法主清
气化痰丸（如胆南星、半夏、橘红、枳实、杏仁、栝蒌仁、黄芩、白茯苓，共为末，姜汁为丸，姜汤化服）。重
者古法主苏葶滚痰丸（如苏子、苦葶苈、大黄、沉香、黄芩、青礞石，共为末，水泛为丸），量儿虚实服之，姜
汤送下。
〔真按〕燥痰必涩滞难出，如南星、半夏、姜汁等味。既虑其愈结愈坚，葶苈、礞石、沉香并用。又虑其
愈破愈弱，但以苦杏仁二钱，栝蒌仁钱半，川贝母一钱，新竹茹钱半，麸炒枳壳八分，莱菔子五分，引用竹沥汁
十滴，重者本方加甜葶苈三分。
小儿阴黄，是由于脾湿与肾寒两种虚损共同作用而形成的，这是最为危险的证候。如果使用温补脾阳的方法治疗阴黄，古法主张使用理中汤加入茵陈蒿。
如果使用温补肾阳的方法治疗阴黄，古法主张使用茵陈四逆汤（包含制附子、北干姜、茵陈蒿、炙甘草等药物）。
〔真按〕阴黄证完全不是湿热所致，总归是气血衰败的结果。因为气不能生血，所以导致血败；血不能荣华面色，所以导致面色败坏。凡是患病发黄且完全没有阳证和阳脉表现的，就是阴黄。这可能是因为大病之后，或者脾胃长期亏损，导致脾土的颜色自然显露于体表。必然会出现喜欢安静厌恶活动、喜欢昏暗畏惧明亮、精神困倦、言语声音轻微、怕冷、食欲减少、四肢无力，或者大便不成形、小便像膏脂一样浑浊等症状，这些都是阳气虚衰的重症表现，与阳黄截然相反，如同冰炭不相容。方药使用炒党参一钱半，生白术二钱，白扁豆一钱，化橘红五分，炮姜炭五分，当归身八分，炙甘草六分，加水一杯半，煎煮至七分，服用。
痰原本是由水谷精微转化而来的，为什么转化后的物质会变成痰呢？这是因为转化生成的津液不能均匀布散全身，停滞在胸中，变成了浊液，所以医书多将责任归于脾。认为脾气清澈则不生痰，脾气浊混则痰才形成。小儿的痰，多由乳食没有节制，或者过食浓腻厚味的食物，导致脾胃不能运化而产生。如果小儿素来阴气旺盛，则转化为饮邪；如果素来阳气旺盛，则转化为痰。医书又说痰的标在脾，痰的本在肾。这是因为脾属于后天之本，肾属于先天之本。凡是后天的疾病，没有不根源于先天所导致的。表层的痰适宜用发散法，热痰适宜用涌吐法，实痰适宜用降泄法，寒痰适宜用燥湿法。痰的变化虽然千变万化，但对于小儿来说，只分为燥痰和湿痰两种类型。这是治疗小儿痰证最简单、最切要的好方法。
小儿燥痰，是因为痰因火邪扰动而生成。火邪旺盛则痰多且粘稠，气机上逆导致气喘咳嗽，夜间睡眠不安宁，面色发红，口干，小便黄赤。轻症的古法主张使用清气化痰丸（包含胆南星、半夏、橘红、枳实、杏仁、栝蒌仁、黄芩、白茯苓，共研为末，用姜汁制成丸剂，用姜汤送服）。重症的古法主张使用苏葶滚痰丸（包含苏子、苦葶苈、大黄、沉香、黄芩、青礞石，共研为末，用水泛为丸），根据小儿体质的虚实情况服用，用姜汤送下。
〔真按〕燥痰必然涩滞难以咳出，如南星、半夏、姜汁等药物。既担心痰结越来越坚固，所以同时使用葶苈、礞石、沉香以破结。又担心攻伐太过导致正气愈弱，所以仅使用苦杏仁二钱，栝蒌仁一钱半，川贝母一钱，新竹茹一钱半，麸炒枳壳八分，莱菔子五分，引用竹沥汁十滴作为药引，重症者在本方基础上加甜葶苈三分。
Pediatric Yin Jaundice is formed by the dual deficiency of Spleen Dampness and Kidney Cold; this is a most critical condition. If treating Yin Jaundice by warming the Spleen, ancient methods primarily prescribe Lizhong Tang (Replenish the Middle Decoction) with added Yinchen Hao (Artemisiae Scopariae Herba).
If treating Yin Jaundice by warming the Kidney, ancient methods primarily prescribe Yinchen Sini Tang (Artemisiae Scopariae and Aconite Root Decoction) (containing ingredients such as Zhi Fuzi (Prepared Aconiti Lateralis Radix), Bei Ganjiang (Dried Ginger Rhizome), Yinchen Hao (Artemisiae Scopariae Herba), and Zhi Gancao (Honey-fried Glycyrrhizae Radix et Rhizoma)).
[True's Note] The syndrome of Yin Jaundice is entirely distinct from Damp-Heat; it stems fundamentally from the collapse of Qi and Blood. Since Qi fails to generate Blood, Blood collapses; since Blood fails to nourish the complexion, the complexion deteriorates. Any case of jaundice presenting without any Yang syndrome signs or Yang pulse manifestations is classified as Yin Jaundice. This may occur after a severe illness or due to long-term depletion of the Spleen and Stomach, causing the color of Spleen Earth to manifest externally on the body. Symptoms invariably include a preference for stillness over activity, a preference for dimness over brightness, mental fatigue, faint speech, aversion to cold, reduced appetite, weakness in the four limbs, possibly loose stools, and urine resembling paste. These are all heavy signs of Yang deficiency, standing in stark contrast to Yang Jaundice, like ice and charcoal. The prescription consists of Chao Dangshen (Stir-fried Codonopsis Radix) 1.5 qian, Sheng Baizhu (Raw Atractylodis Macrocephalae Rhizoma) 2 qian, Bai Biandou (White Lablab Seed) 1 qian, Hua Juhong (Exocarpium Citri Reticulatae Viride) 0.5 qian, Pao Jiangtan (Charred Ginger Rhizome) 0.5 qian, Bai Guishen (Angelicae Sinensis Radix) 0.8 qian, and Zhi Gancao (Honey-fried Glycyrrhizae Radix et Rhizoma) 0.6 qian. Add one and a half cups of water, decoct to seven-tenths volume, and administer.
Phlegm is originally transformed from food and drink. Why does the transformed substance become Phlegm? Because the generated Jin-Ye (Body Fluids) fail to distribute evenly throughout the body, stagnating in the chest and transforming into turbid fluid; thus, medical texts often attribute the responsibility to the Spleen. It is stated that when Spleen Qi is clear and pure, Phlegm is not generated; when Spleen Qi is turbid and mixed, Phlegm forms. Pediatric Phlegm mostly arises from irregular breastfeeding or feeding, or excessive consumption of rich and greasy foods, leading to the Spleen and Stomach's inability to transport and transform. If the child possesses abundant Yin Qi naturally, it transforms into Yin (Fluid Retention); if the child possesses abundant Yang Qi naturally, it transforms into Phlegm. Medical texts also state that the branch of Phlegm lies in the Spleen, while its root lies in the Kidney. This is because the Spleen belongs to the Postnatal Foundation, and the Kidney belongs to the Prenatal Foundation. Any disease of the Postnatal Foundation inevitably has its roots in the Prenatal Foundation. Superficial Phlegm should be dispersed, Heat Phlegm should be vomited out, Excess Phlegm should be purged downward, and Cold Phlegm should be dried. Although Phlegm changes in myriad ways, in children, it is only divided into two types: Dry Phlegm and Damp Phlegm. This is the simplest and most essential effective method for treating pediatric Phlegm syndromes.
Pediatric Dry Phlegm occurs when Phlegm is stirred by Fire. When Fire is excessive, Phlegm becomes abundant and sticky, Qi rebels causing wheezing and coughing, restless sleep at night, red face, dry mouth, and yellow-red urine. For mild cases, ancient methods primarily prescribe Qingqi Huatan Wan (Clear Qi and Resolve Phlegm Pill) (containing Dan Nanting (Arisaematis Cum Bile), Banxia (Pinelliae Rhizoma), Juhong (Exocarpium Citri Reticulatae Viride), Zhishi (Aurantii Fructus Immaturus), Xingren (Prunus Armeniacae Semen), Gualouren (Trichosanthis Semen), Huangqin (Scutellariae Radix), and Bai Fuling (Poria), ground into powder, formed into pills with Ginger Juice, and taken with Ginger Soup). For severe cases, ancient methods primarily prescribe Su Ting Gun Tan Wan (Perilla and Lepidium Rolling Phlegm Pill) (containing Suzi (Perillae Fructus), Ku Tingli (Lepidii Semen), Dahuang (Rhei Radix et Rhizoma), Chenxiang (Aquilariae Lignum Resinatum), Huangqin (Scutellariae Radix), and Qing Mengshi (Calcaris Calcitae)), formed into pills using water suspension, administered according to the child's excess or deficiency status, delivered with Ginger Soup.
[True's Note] Dry Phlegm is necessarily viscous and difficult to expectorate, involving substances like Nanting, Banxia, and Ginger Juice. One must worry that the accumulation will become harder and harder, hence Tingli, Mengshi, and Chenxiang are used together to break up the accumulation. One must also worry that aggressive breaking will weaken the patient further, so only Ku Xingren (Bitter Apricot Seed) 2 qian, Gualouren (Trichosanthis Semen) 1.5 qian, Chuan Beimu (Fritillariae Cirrhosae Bulbus) 1 qian, Xin Zhuru (Fresh Bamboo Shavings) 1.5 qian, Fu Chao Zhiqiao (Bran-fried Aurantii Fructus) 0.8 qian, and Laifuzi (Radish Seed) 0.5 qian are used, with Zhuli (Bamboo Sap) 10 drops as the guiding agent. In severe cases, add Tian Tingli (Sweet Lepidium Seed) 0.3 qian to this formula.
