胎儿居于母体中，总不免感染七情六欲以及饮食之毒，故胎儿未产之前，胎毒已随日积月累而蕴藏于
躯体之中，不过毒有轻有重之别，他日发为口病、游丹、疹痘、惊热等症，亦有甚与不甚之差，初生之去毒，
盖藉药物之力，冀以减轻其毒邪，为预防后患计耳，其法内服外治，相沿有数种，兹述之如后。
一、内服去毒方
（一）以甘草煎汤，用胡桃肉去皮研烂，取薄纱包胡桃肉如小枣，随时蘸甘草之汁，纳儿口中，任其吮汁。
（二）用当归尾、红花、桃仁、甘草、大黄各五分煎汁，尽生下六个时辰内服完。
（三）用甘草、淡豆豉浓煎汁与三五口。
（四）用三黄汤（黄连、黄柏、黄芩或作大黄、黄连、黄芩）时时服之。
（五）用淡姜汤喂之。
（六）用犀黄三五分，随时置少许于舌上，任其自然咽下。
以上六方，第一、二、三方，皆可通用；第四方则孕妇素体热而胎火旺者，宜多服之；第五方则冬季
生产，婴孩受寒，面色 白，唇色淡红者适用之；第六方则婴孩血热，发生游丹或口疳
者适用之。凡此等去毒之法，无非使婴孩蕴结于肠胃之秽物，畅下无阻，则后天既洁净以无瑕，先天之伏
毒，亦得以解除不少也。小儿经此去毒之法以后，必解出黑粪二三次，或历二三日而
未已，此粪谓之胎粪，胎粪既净，渐见嫩黄之稀粪，是为肠胃已清，后天正式之胃气始萌矣。
二、外治去毒方
（一）用黄栀子、桃仁、杏仁各一粒，白胡椒三粒，共研细末，取乌骨鸡蛋清调和之，于婴孩未盈月前
包敷足心，男左女右，一周时解下，足心现青黑之色，可免婴孩将来惊热之病。
（二）用川白蜜、小磨麻油、鸡蛋清、黄酒各一调羹和匀，于婴孩三朝洗浴时，先敷前胸，次敷后
背，用新木梳略梳几梳后，以青布轻轻摩擦，如有白毛挺出，将镊子齐根拔出净尽，其
毛尖头黑而粗，极坚硬，长五六分，其余两手心、两足心、脑后、两肩、尾骨等处，只须如法挨次而行，
至少有数十根，多则二百余根为率，无论多少，总宜擦遍拔完，惟所擦各处，有无不定，若竟无一根擦出者，
可保长生少病，其有者，即夭折之根苗，一经拔出，可以止惊稀痘，免除一生大病小恙。
以上二方，第一方凡婴孩生下，人人可为，第二方宜于天气
和暖之时候行之，若天气严寒，反恐受冻不宜也。
While in the womb, the fetus is inevitably exposed to "toxins" arising from the Seven Emotions and Six Desires (psychological and physiological stimuli) as well as improper diet. Therefore, before birth, fetal toxins accumulate over time and lodge within the body. However, these toxins vary in severity, and may later manifest as oral diseases (such as mouth sores), Youdan (a type of acute erythematous skin disease), rashes and pustules, or convulsive fever, with varying degrees of intensity. The removal of toxins in newborns relies on medicinal power to alleviate these pathogenic factors, serving as a preventive measure against future ailments. These methods include internal administration and external treatment, with several traditional approaches described below.
I. Internal Methods for Toxin Removal
(1) Decoct Licorice Root (Gancao, 甘草) in water. Peel walnuts, grind them into a paste, wrap the walnut paste in thin gauze to form a shape resembling a small jujube, dip it frequently into the licorice decoction, place it in the infant's mouth, and allow the infant to suck the juice.
(2) Use Radix Angelicae Sinensis Tail (Dangguiwei, 当归尾), Flos Carthami (Honghua, 红花), Semen Persicae (Taoren, 桃仁), Radix Glycyrrhizae (Gancao, 甘草), and Radix et Rhizoma Rhei (Dahuang, 大黄), each weighing five fen. Decoct in water and ensure the entire dose is administered within six shichen (twelve hours) after birth.
(3) Decoct Radix Glycyrrhizae (Gancao, 甘草) and Fermented Soybean (Danshidouchi, 淡豆豉) into a concentrated decoction, and feed a few mouthfuls to the infant.
(4) Administer Sanhuang Tang (Three Yellows Decoction), composed of Rhizoma Coptidis (Huanglian, 黄连), Cortex Phellodendri (Huangbai, 黄柏), and Radix Scutellariae (Huangqin, 黄芩), or alternatively Radix et Rhizoma Rhei (Dahuang, 大黄), Rhizoma Coptidis (Huanglian, 黄连), and Radix Scutellariae (Huangqin, 黄芩). Give small amounts frequently.
(5) Feed the infant with light Ginger Decoction (Jiangtang, 姜汤).
(6) Place three to five fen of Rhinoceros Horn Powder (Xihuang, 犀黄) on the infant's tongue at any time, allowing it to be swallowed naturally.
Among the above six formulas, the first three are generally applicable. The fourth formula is suitable for infants born to mothers with a constitution prone to heat and excessive fetal fire. The fifth formula applies to winter births where the infant has contracted cold, presenting with pale complexion and pale-red lips. The sixth formula is indicated for infants with blood-heat conditions, manifesting as Youdan or Kougan (mouth ulcers). These toxin-removal methods aim to facilitate the smooth expulsion of filth accumulated in the intestines and stomach. Once the postnatal foundation is cleansed, the latent congenital toxins can be significantly alleviated. After undergoing this procedure, the infant will typically pass black meconium two or three times, possibly continuing for two to three days. This stool is known as meconium. Once the meconium is cleared and tender yellow loose stools appear, it indicates that the intestines and stomach are clean, and the functional Qi of the Stomach (postnatal Qi) begins to emerge.
II. External Methods for Toxin Removal
(1) Grind one seed of Gardenia Fruit (Zhizi, 黄栀子), one seed of Peach Kernel (Taoren, 桃仁), one seed of Apricot Kernel (Xingren, 杏仁), and three grains of White Pepper (Baihujiao, 白胡椒) into a fine powder. Mix with the egg white of a Silkie Chicken Egg (Wuji Danqing, 乌骨鸡蛋清). Apply this mixture to the sole of the foot before the infant reaches one month of age, covering the left foot for males and the right foot for females. Remove after one week. If the sole turns bluish-black, it helps prevent future convulsive fever.
(2) Mix one spoonful each of Sichuan White Honey (Chuanbaimi, 川白蜜), Sesame Oil (Mazhi, 麻油), Egg White (Danqing, 蛋清), and Yellow Wine (Huangjiu, 黄酒). On the third day after birth, during bathing, apply the mixture first to the anterior chest and then to the posterior back. Gently comb with a new wooden comb, then rub lightly with a blue cloth. If coarse, black-tipped hairs protrude, pluck them out completely with tweezers. These hairs are hard, black at the tip, and about five to six fen long. Repeat this process sequentially on both palms, both soles, the back of the head, both shoulders, and the coccyx. At least dozens of hairs, up to over two hundred, may be extracted. Regardless of the quantity, all should be removed. The presence of such hairs varies by location. If no hairs are extracted, the child is likely to enjoy longevity and good health. If hairs are present, they are considered signs of potential early mortality; removing them can prevent convulsions, reduce the severity of smallpox/rashes, and avert major and minor illnesses throughout life.
Regarding these two external methods: The first method can be performed by anyone immediately after birth. The second method is suitable only when the weather is warm; in severe cold, it should be avoided to prevent chilling the infant.
