初生小儿，阴阳变蒸于气血，而使形体成就，由五脏之变蒸，而七情所以生也。变者，性情
变易也；蒸者，身体蒸热也。儿当变蒸之候，身热目倦，耳尻俱冷，上唇白泡如珠，微惊而不乳
哺。甚则躁渴、夜啼，伤寒相似，或自汗盗汗，先期发热，七日自安，不必服药，反致惊恐。但
宜避风寒，少乳食，谨慎调护。自初生三十二日为一变，首生肾经（天一生水）；六十四日二变
兼蒸，生膀胱；九十六日三变，生心（地二生火）；一百二十八日并蒸，生小肠。五生肝，六生
胆，七生肺，八生大肠，九生脾。三百二十日十变并蒸，生胃（未满，此脾胃犹未成全，而与难化
之物食之，安有不致伤而成病者，譬如磨齿未凿，可能磨物乎？）每生一脏，成一智能。过期不
愈，抱龙丸、惺惺散治之（方见后条。） 如有杂证相仍，随病调理。（儿壮气实不热者，名暗变）
。若与伤寒疑似，服后方或参苏饮之类。
主方 紫苏 羌活 防风 川芎 白芷 柴胡 黄芩 桔梗 陈皮（各五分） 甘草（二
分）姜、枣煎服。
胎热者。小儿在胎，母食热毒之物；或服热药。致儿生下，身热面赤，眼合痰喘，大便秘，
小便赤。若不治，则鹅口、重舌、赤瘤、急惊等证生焉。治宜先用木通汤煎与母服，使通于乳，
令儿饮之。通心气，解烦热。母忌辛辣、酒面浓味。儿服甘豆汤及古方化毒丹。

初生的婴儿，其阴阳之气在气血中发生变动与蒸腾，从而使形体发育成熟。随着五脏的变蒸过程，人的七情（喜、怒、忧、思、悲、恐、惊）也随之产生。所谓“变”，是指性情发生变化；所谓“蒸”，是指身体出现蒸热现象。当小儿处于变蒸时期时，会出现身体发热、眼睛疲倦、耳朵和臀部发凉、上唇出现如珍珠般的白色小泡、轻微惊悸且不愿吃奶等症状。严重的则表现为烦躁口渴、夜间啼哭，症状类似伤寒，或者出现自汗（白天不因活动而出汗）和盗汗（夜间睡着后出汗），提前发热，经过七天自然痊愈，不需要服药，否则反而会导致惊恐。此时只宜避开风寒，减少乳食摄入，谨慎地进行护理调养。从出生起，三十二天为第一次“变”，首先生肾经（依据天一生水的理论）；六十四天为第二次“变”兼有“蒸”，生出膀胱；九十六天为第三次“变”，生出心（依据地二生火的理论）；一百二十八天为第四次“变”兼有“蒸”，生出小肠。第五变生肝，第六变生胆，第七变生肺，第八变生大肠，第九变生脾。三百二十天为第十次“变”兼有“蒸”，生出胃（此时脾胃尚未完全长成，如果给这种未成熟的脾胃喂食难以消化的食物，怎么会导致损伤而生病呢？这就好比牙齿还未长出，怎么能用来磨碎食物呢？）每生成一个脏腑，就形成一种智能。如果超过期限症状仍未缓解，可用抱龙丸、惺惺散治疗（方剂见后文）。如果有其他杂症接连出现，根据病情进行调理。（如果小儿体质壮实、气息充足且不发热，称为“暗变”）。如果症状与伤寒相似，服用后面的方子或参苏饮之类的药物。
主方：紫苏、羌活、防风、川芎、白芷、柴胡、黄芩、桔梗、陈皮（各五分）、甘草（二分），加生姜、大枣煎服。
胎热证：小儿在母体中时，母亲食用了热毒之物，或服用了热性药物，导致孩子出生后身体发热、面色红润、眼睛紧闭伴有痰喘、大便秘结、小便颜色深红。如果不治疗，就会引发鹅口疮、重舌、赤瘤、急惊风等病症。治疗宜先用木通汤让母亲服用，使药力通过乳汁传递，让孩子饮用。以此通达心气，解除烦热。母亲忌食辛辣、酒类、面食及浓味食物。孩子服用甘豆汤及古方化毒丹。
主方（乳母与孩子同服）：木通、扁豆（各一钱半）、赤茯苓、甘草（各一钱）、大黄（五分）、滑石（研末）、栀子、车前子、黄芩、瞿麦（各八分），加灯心草、薄荷用水煎服。
甘豆汤：治疗胎热。黑豆（二钱）、甘草（一钱）、淡竹叶（十片）、灯心草（七茎），用水煎煮。
化毒丹：治疗热邪蕴积，口舌生疮，遍身瘙痒，游风丹毒，疮疡疥癣，以及初生儿一切因胎中热毒导致的疾病，还有痘疹后的余毒隐患，均能治疗。玄参、桔梗（各一两）、茯苓（八钱）、青黛（画家用的那种）、甘草（各三钱）、牙硝（二钱）。以上药材研成粉末，混合青黛、牙硝和蜂蜜制成如弹子大小的丸剂，用金银箔包裹衣面。每次服用半丸，用薄荷泡的水调化，涂抹在孩子口腔内患处，或用汤送服。
Newborn infants undergo the transformation and steaming of Yin and Yang within their Qi and Blood, leading to the maturation of their physical form. Through the transformation and steaming of the Five Zang Organs, the Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright) arise. "Transformation" refers to changes in temperament; "steaming" refers to the sensation of heat rising in the body. During the period of transformation and steaming, infants may exhibit symptoms such as low-grade fever, lethargic eyes, cold ears and buttocks, white bubbles on the upper lip resembling pearls, mild fright, and refusal to nurse. In severe cases, there may be restlessness, thirst, nocturnal crying, symptoms resembling Taiyang disease (a syndrome caused by pathogenic factors affecting the Taiyang meridian), spontaneous sweating (daytime sweating without exertion), or night sweats (sweating during sleep). Fever may appear earlier than expected but resolves spontaneously after seven days. Medication is unnecessary; administering drugs may instead cause fright. One should only avoid wind and cold, reduce milk and food intake, and provide careful nursing care. Starting from birth, thirty-two days constitute the first "transformation," generating the Kidney Meridian (based on the principle that Heaven generates Water); sixty-four days constitute the second "transformation" accompanied by "steaming," generating the Bladder; ninety-six days constitute the third "transformation," generating the Heart (based on the principle that Earth generates Fire); one hundred twenty-eight days constitute the fourth "transformation" accompanied by "steaming," generating the Small Intestine. The fifth transformation generates the Liver, the sixth generates the Gallbladder, the seventh generates the Lungs, the eighth generates the Large Intestine, and the ninth generates the Spleen. Three hundred twenty days constitute the tenth "transformation" accompanied by "steaming," generating the Stomach (at this stage, the Spleen and Stomach are not yet fully formed; feeding them indigestible substances would inevitably cause injury and illness, just as uncut teeth cannot grind food). With the generation of each organ, a specific intelligence develops. If symptoms persist beyond the expected time, Baolong Wan (Dragon Embracing Pill) or Xingxing San (Stirring Powder) may be used (formulas see later sections). If other miscellaneous syndromes occur consecutively, treat according to the specific condition. (If the infant is robust, has sufficient Qi, and does not have a fever, it is called "hidden transformation"). If symptoms resemble Taiyang disease, administer the following formula or similar preparations like Rensu Yin (Ginseng and Perilla Decoction).
Main Formula: Zi Su (Perillae Folium), Qiang Huo (Notopterygii Rhizoma et Radix), Fang Feng (Saposhnikoviae Radix), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Bai Zhi (Angelicae Dahuricae Radix), Chai Hu (Bupleuri Radix), Huang Qin (Scutellariae Radix), Jie Geng (Platycodonis Radix), Chen Pi (Citri Reticulatae Pericarpium) (each 0.5 fen), Gan Cao (Glycyrrhizae Radix et Rhizoma) (0.2 fen). Decoct with Sheng Jiang (Zingiberis Rhizoma Recens) and Da Zao (Jujubae Fructus) and take orally.
Fetal Heat Syndrome: While in the womb, if the mother consumes foods with heat-toxicity or takes heat-inducing medicines, the newborn may present with body heat, flushed face, closed eyes with phlegm and wheezing, constipation, and dark red urine. If untreated, conditions such as oral thrush (E Kou), double tongue (Chong She), red tumors, and acute convulsive disorder (Ji Jing Feng) may develop. Treatment should initially involve Mu Tong Tang (Akebia Decoction) administered to the mother so that its effects transfer through breast milk for the infant to drink. This promotes Heart Qi and resolves irritability and heat. The mother should avoid spicy, alcoholic, wheat-based, and rich-flavored foods. The infant should receive Gandou Tang (Black Bean Decoction) and the ancient formula Huadu Dan (Toxin-Resolving Pill).
Main Formula (administered to both lactating mother and infant): Mu Tong (Akebiae Caulis), Bian Dou (Dolichoris Semen) (each 1.5 qian), Chi Fu Ling (Poria Cocos with Red Cortex), Gan Cao (Glycyrrhizae Radix et Rhizoma) (each 1 qian), Da Huang (Rhei Radix et Rhizoma) (0.5 fen), Hua Shi (Talcum, ground), Zhi Zi (Gardeniae Fructus), Che Qian Zi (Plantaginis Semen), Huang Qin (Scutellariae Radix), Qu Mai (Persicariae Herba) (each 0.8 fen). Decoct with Deng Xin Cao (Junci Medullia) and Bo He (Menthae Haplocalycis Herba) in water and take orally.
Gandou Tang: Treats fetal heat. Hei Dou (Sojae Semen Nigrum) (2 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma) (1 qian), Dan Zhu Ye (Lophatheri Herba) (10 leaves), Deng Xin Cao (Junci Medullia) (7 stems). Decoct in water.
Huadu Dan: Treats accumulation of heat pathogens, mouth and tongue ulcers, generalized pruritus, migratory wind dan-du (erysipelas-like eruptions), sores, carbuncles, scabies, tinea, all diseases caused by fetal heat-toxicity in newborns, and residual toxicity after smallpox/variolous eruptions. Xuan Shen (Scrophulariae Radix), Jie Geng (Platycodonis Radix) (each 1 liang), Fu Ling (Poria Cocos) (8 qian), Qing Dai (Indigo Naturalis, artist grade), Gan Cao (Glycyrrhizae Radix et Rhizoma) (each 3 qian), Ya Xiao (Natrii Sulfas) (2 qian). Grind into powder, mix with Qing Dai, Ya Xiao, and honey to form pills the size of beans, coated with Jin Yin Bo (Gold Leaf). Take half a pill at a time, dissolve in mint-infused water, apply to the inside of the infant's mouth, or swallow with decoction.
