撮口者，因胎受风热，初生又感风邪，入脐流毒心脾而致也。然胎风、脐风等症，
皆令气促舌强，握口如囊而不乳，病原相类，候亦相同，发则面目黄赤，撮口不乳，
气促喘急，啼声不出，舌强唇青，聚口撮面，饮乳有妨，治宜疏利，故书曰∶小儿初
生，血脉未敛，肌肉犹血，血凝且坚，方成
肌骨。血若治败，则不成肌肉，致令面目皆黄，闭目口撮，是皆血脉不敛也。总由在母
胎中，挟于风热，既生之后，气皿未调，当风洗浴，风入心脾，皆能撮口。因肠胃闭
塞，郁结于中，是以腹中胀满，肚上青筋，撮口不乳，势甚危急。若不速与利下，则难
救疗。如过一腊而不愈，口吐白沫，四肢觉冷者，不治。况小儿初生，其气尚盛，且有
病则病当之。若一见前候，须急下之，愈后微加补益，否则根本一伤，终身多病。
噤风、风噤、口噤者，均因胎受热毒，流入心脾，既生又为风邪侵袭而作。其症眼
闭口噤，啼声渐小而不乳，舌上聚肉如粟米，口吐白沫，色赤鼻黄，如百日内见名绝
风噤。然噤风、风噤、口噤三症，与脐风、撮口症候相类，治法亦不大异，总为恶候。
如逆搐噤口，脐内流血不止者，死。若口开有物如蜗牛，或似黄头白虫者，宜内服竹
沥、牛黄之类，外用猪油薄切擦消。及看上 有白泡子，用指甲轻轻刮破，以京墨涂
之。故初生须防三疾，一曰口噤；二曰撮口；三曰脐风。皆是急病，就中噤口尤甚，
若过一腊，方免此厄。故略见牙关紧急，不便食乳，啼音渐小，口吐涎沫，便即须照前
法观看口舌，如法治之，然后服药。诸症病名难异，病源则同。脐风、撮口、噤口者，
多生于七日之中，及一月之内名之也。噤风、风噤者，以病生于百日之内，及一百二
十日之前名之也。
撮口症，是由于胎儿在母体内感受风热之邪，出生后再次感受风邪，邪气侵入脐部并流注于心脾所致。然而胎风、脐风等病症，都会导致气息急促、舌体僵硬，嘴巴紧闭如囊状而不能吸吮乳汁，其病因相似，症状也相同。发作时面色黄赤，嘴唇紧缩不能吃奶，呼吸急促喘息，啼哭无声，舌体强硬嘴唇发青，口唇面部肌肉收缩聚拢，影响进食哺乳，治疗应当采用疏泄通利的方法。所以医书说：小儿刚出生时，血脉尚未收敛，肌肉如同血液般未固，只有血凝且坚实，才能形成肌骨。如果血液治理失败（指气血运行失常），则无法形成正常的肌肉，导致面目皆黄，闭目口唇紧缩，这都是因为血脉未能收敛的缘故。总归是因为在母胎中夹杂了风热之邪，出生后气血未调和，对着风洗浴，风邪侵入心脾，都能导致撮口症。由于肠胃闭塞不通，郁结在中焦，所以腹部胀满，肚上显现青色筋脉，嘴唇紧缩不能吃奶，病情非常危急。如果不迅速给予通下之法，就难以救治。如果超过一个月（一腊）仍不痊愈，口吐白沫，四肢感觉冰冷的，属于不治之症。况且小儿初生，元气尚盛，有病则病邪会自行承受冲击。若一见上述症状，必须紧急使用下法，治愈后稍加补益，否则根本一旦受损，终身多病。
噤风、风噤、口噤症，均是因为胎儿受热毒侵袭，流入心脾，出生后又被风邪侵犯而发病。其症状表现为眼睛闭合、牙关紧闭，啼哭声逐渐变小而不能吃奶，舌头上聚集的肉粒像粟米一样，口吐白沫，面色红赤、鼻头发黄，如果在百日内出现这种情况，称为“绝风噤”。然而噤风、风噤、口噤这三种病症，与脐风、撮口症的症状相似，治疗方法也不大不同，总体都属于恶候。如果出现逆搐、牙关紧闭、脐部流血不止的，预后不良致死。如果口张开有物体伸出像蜗牛，或者像黄头白虫的样子，适宜内服竹沥、牛黄之类的药物，外用猪油薄切涂抹擦拭以消散病灶。以及看到眼皮上有白色小泡，用指甲轻轻刮破，用京墨涂在上面。所以新生儿须防备三种疾病，一是口噤；二是撮口；三是脐风。这些都是急症，其中口噤最为严重，如果超过一个月，才能免除这种灾厄。因此只要略微见到牙关紧急，不便吃奶，啼哭声渐小，口吐涎沫，就必须立即按照前面的方法观察口舌，依照法治疗，然后再服药。这些病症名称虽难区分，但病因源头相同。脐风、撮口、口噤症，多发生在出生七天之内，以及一个月以内，故以此命名。噤风、风噤症，是因为病发生在百日之内，及一百二十天之前，故以此命名。
Chuekou (Mouth Pinching) syndrome is caused by the fetus contracting wind-heat pathogens in the womb, followed by exposure to wind pathogens after birth. The pathogenic factors enter the umbilicus and flow into the Heart and Spleen. However, conditions such as Taifeng (Fetal Wind) and Qifeng (Umbilical Wind) all lead to rapid breathing, a stiff tongue, and a mouth closed tightly like a pouch, preventing breastfeeding. Their etiology is similar, and their manifestations are identical. Upon onset, the face appears yellowish-red, the mouth pinches shut preventing feeding, breathing becomes rapid and labored, crying sounds are absent, the tongue is stiff, and the lips turn cyanotic. The mouth and facial muscles contract and gather, hindering nursing. Treatment should focus on dispersing and purging. Therefore, medical texts state: When a newborn is born, the blood vessels have not yet consolidated, and the muscles are still fluid-like; only when the blood coagulates and hardens can muscle and bone form. If the blood fails to regulate properly, normal muscle formation will not occur, resulting in a yellowish complexion and closed eyes with pinched mouth, which indicates that the blood vessels have failed to consolidate. This is ultimately due to the presence of wind-heat pathogens during gestation. After birth, if the Qi and Blood are unbalanced, bathing in drafts allows wind pathogens to invade the Heart and Spleen, leading to Chuekou. Due to blockage in the intestines and stomach, stagnation occurs in the middle jiao, causing abdominal distension, visible blue veins on the abdomen, pinched mouth, and inability to nurse. The condition is critical. If purgative treatment is not administered promptly, rescue is difficult. If the condition persists beyond one lunar month without improvement, accompanied by foaming at the mouth and cold limbs, it is considered incurable. Moreover, newborns possess vigorous vital energy, and pathology tends to be contained by this robust constitution. Upon observing these signs, immediate purgation is required. After recovery, mild tonification should be added; otherwise, damage to the root will result in lifelong illness.
Jinfeng (Wind Lock), Fengjin (Wind Stiffness), and Koujin (Mouth Lock) syndromes are all caused by heat-toxins contracted in utero, flowing into the Heart and Spleen, and further exacerbated by wind-pathogen invasion after birth. Symptoms include closed eyes, jaw stiffness, diminishing cry, inability to nurse, millet-grain-like nodules on the tongue, foaming at the mouth, red complexion, and a yellow nasal tip. If these appear within the first hundred days, it is termed "Juefeng Jin" (Desperate Wind Stiffness). These three conditions share similarities with Qifeng and Chuekou in symptoms and treatment methods, and are generally classified as malignant prognoses. If accompanied by convulsive jerking, jaw lock, and continuous bleeding from the umbilicus, death ensues. If an object resembling a snail or a white worm with a yellow head protrudes from the open mouth, internal administration of Zhuli (Bamboo Sap) and Niuhuang (Calculus Bovis) is indicated, along with external application of thinly sliced pork fat to dissipate the lesion. If white blisters are observed on the eyelids, they should be gently scratched open with fingernails and coated with Jingmo (Beijing Ink). Therefore, three diseases must be prevented in newborns: first, Koujin; second, Chuekou; third, Qifeng. All are acute conditions, with Koujin being the most severe. Survival is possible only if the condition resolves within one month. Thus, upon slight observation of jaw stiffness, difficulty nursing, diminished crying, and salivation, one must immediately examine the mouth and tongue according to previous methods, treat accordingly, and then administer medication. Although disease names may vary, their etiologies are identical. Qifeng, Chuekou, and Koujin typically arise within seven days of birth or within one month. Jinfeng and Fengjin are named based on their occurrence within one hundred days or before one hundred twenty days of age.
