脐为百风总窍，五脏寒门，道家谓之下丹田，为人身之命蒂。儿在胎时，口鼻未通呼吸，惟脐间真息，随
母之呼吸为呼吸；及其下地，囫底一声，气通口鼻，而胎元之一息，不复为用矣。遂寄于脐内一寸三分，中
虚一穴，左青右白，上赤下黑，中央黄色，八脉九窍，经纬联系，为真息往来之路，坎离交会之乡，凡修炼仙
胎，皆从此处立基，所以谓之命蒂。故小儿初生，惟脐之干系最重。断脐之时，不可不慎，或剪脐带太短，或
束不紧，致外风侵入脐中，或浴儿时牵动脐带，水入生疮，客风乘虚而入，内伤于肾，肾传肝，肝传心，心传
脾，脾传肺，蕴蓄其毒，发为脐风。其证面赤啼叫者心病，手足微搐者肝病，唇青口撮，痰涎壅塞者脾病，牙
关紧急者肾病，啼哭不止者肺病。五脏之证略见一二者，犹可治，悉见者不治。
小儿初生，惟脐风为恶候。其证有三∶曰脐风，曰噤口，曰锁肚。虽皆脐证，而寒热自别，治者宜详。
一曰脐风。由断脐后为水湿风寒所乘，入于脐而流于心脾，令肚腹胀满，吮乳口松，多啼不乳，此初起之
时，速用火攻散之。若至气息喘急，啼声不出，或肚上青筋，吊疝作痛，此胎毒夹风邪入脏，外用火功，内服
指迷七气汤方见二卷胎毒门二。若肚脐青肿，撮
口不开，牙关紧闭，口吐白沫，爪甲青黑者，皆不治。
一曰噤口。其证眼闭口噤，啼声渐小，舌上聚肉如粟米状，吮乳不得，口吐白沫，大小便不通。遇此先看
其上 有点子，即以指甲轻轻刮破，以木香、白蔻仁各五分，煎汤化下沆瀣丹，利动脏腑，气顺自愈。
一曰锁肚。由胎中热毒壅盛，结于肛门，大便不通。急令妇女温水漱口，吮儿之前后心，并脐下及手足心，
共七处，凡四五次；外以轻粉五分研末，蜂蜜少许，温水调服，以通为度。如更不通，以葱白三四寸长，用油
抹润，轻透谷道，纳入二寸许，以通为快，若至七日不通者死。
古人之论脐风，皆谓由于水湿风冷所致，予则以为古论犹未尽也。盖脐风有内外二因，有可治不可治之别。
外因者，风湿所伤；内因者，禀父母之真阳不足也。予尝见一士，其妻产育十数胎皆男，尽殇于七日内之脐风，
无一存者。若谓外邪所伤，何以独伤此家之儿，又岂无一儿能避之者？此内因之显而易见也。凡男子之命门真
阳不足者，右尺脉必细涩无神，生子必有脐风。此予察之详，见之确，非耳闻者比也。其外因者，病发于二、
三、四、五日之间，病生于六腑，故可治；内因者，必发于六七日之间，病生于五脏，故不可治。曩者，夏禹铸
有预防脐风之诀，谓三朝一七，看儿两眼角黄，必有脐风，不知禀受浓者，生下即满面红黄，乃为吉色，误认
脐风，其害不小，此法不确。惟令乳母每日摸儿两乳，乳内有一小核，是其候也。然乳内有核，发脐风者固多，
而复有不发脐风者，此法十有七八，亦有二三分不确。但看小儿不时喷嚏，更多啼哭，吮乳口松，是真候也，急
宜治之。第脐风之治，无一成法可遵，虽有疏风攻下之法，莫能济急。独予异授灯火，无论脐风痉搐，以及凶
危险证，用药不能挽回者，此火可以生之，久经效验，未肯轻传，因见幼科不知火穴，往往错误用之，反致引
动风邪，蔽
固火毒，致儿身热不退，火毒内攻，每多不救，故不忍隐秘，尽行吐露，以公诸世。世之幼科治病，辄曰剪风，
曰截风。夫剪者，邀遏之谓也；截者，堵塞之谓也。以火功用于中宫任脉所行之地，岂非堵遏其邪，而犯关
门逐盗之戒乎？不知风邪之在人身，善行数变，无形无声，欲除其害，无如疏散条达而去之，不使久羁于荣卫
经络则善矣。如仲景之治伤寒，而立汗吐下三法。邪之在表者，汗而散之；邪之在上者，吐而越之；邪之深入
者，下而夺之。总欲其邪尽而后已，未闻有邀截之为也。今幼科不但不为逐邪，而反闭关绝险，阻其去路，使
邪气进不可，退不能，猖狂踯躅，欲其不倒勿相攻，斩关逆犯者，不可得也。此皆为治者酿成之祸，于邪何尤？
凡邪之伤人，未有不从三阳而入；驱除之法，亦必使其从三阳而出。故此火穴亦惟三阳有之，盖欲引其出表，断
不使之入里也。敬为图说详后，并请政大方。
脐部是风邪入侵的总门户，也是五脏寒邪聚集之处，道家称之为下丹田，是人体生命的根本蒂结。胎儿在母体内时，口鼻尚未建立呼吸功能，仅依靠脐间的真息（先天元气之呼吸），随着母亲的呼吸而进行气体交换；等到婴儿降生落地，发出第一声啼哭，气息便贯通口鼻，此时胎元的那一口先天之气便不再发挥作用了。这口气寄居在脐内一寸三分处，中间空虚形成一个穴位，左边青色，右边白色，上部红色，下部黑色，中央黄色，八脉九窍在此经纬联系，是真息往来的通道，也是坎离（心肾）交会的场所，凡是修炼仙胎功的人，都从这里奠定基础，所以称之为命蒂。因此，小儿初生时，脐部的护理最为关键。断脐的时候，不可不谨慎，如果剪脐带太短，或者捆绑不紧，导致外风侵入脐中；或者给婴儿洗澡时牵动脐带，水进入引起生疮，客风乘虚而入，内伤于肾，肾传肝，肝传心，心传脾，脾传肺，蕴蓄其毒，最终发为脐风。其症状表现为：面赤啼叫的是心病，手足轻微抽搐的是肝病，嘴唇青紫、口唇收缩、痰涎壅塞的是脾病，牙关紧急的是肾病，啼哭不止的是肺病。五脏的症状如果只出现一两种，还可以治疗；如果全部出现，则无法治疗。
小儿初生，以脐风为恶候。其证候有三种：叫做脐风，叫做噤口，叫做锁肚。虽然都属于脐部病症，但寒热性质自不相同，治疗者应当详细辨别。
第一种叫脐风。由于断脐后受到水湿风寒侵袭，邪气进入脐部并流窜于心脾，导致肚腹胀满，吮乳时口松无力，多啼哭但不吃奶，这是初起之时，应迅速用火攻法散邪。如果发展到气息喘急，啼哭无声，或者肚上青筋暴露，吊疝作痛，这是胎毒夹带风邪入脏，外用火功疗法，内服指迷七气汤（见第二卷胎毒门）。如果肚脐青肿，口唇收缩不能张开，牙关紧闭，口吐白沫，指甲青黑，这些都是不治之症。
第二种叫噤口。其症状表现为眼睛闭合、牙关紧闭，啼哭声逐渐变小，舌头上聚生如粟米状的肉粒，无法吮乳，口吐白沫，大小便不通。遇到这种情况，先看其上颚是否有小白点，如果有，就用指甲轻轻刮破，用木香、白蔻仁各五分，煎汤化开沆瀣丹服用，使脏腑通畅，气顺自然痊愈。
第三种叫锁肚。由于胎中热毒壅盛，结于肛门，导致大便不通。急忙让妇女用温水漱口，吸吮婴儿的前后心部位，以及脐下和手足心，共七处，反复四五次；外用轻粉五分研成粉末，加少许蜂蜜，温水调服，以大便通畅为度。如果仍然不通，取葱白三四寸长，用油涂抹润滑，轻轻插入肛门，纳入约二寸许，以通畅为快，如果到第七天仍不通畅，就会死亡。
古人论述脐风，都认为是由水湿风冷所致，我认为古人的论述还不够全面。因为脐风有内外两种病因，有可治与不可治的区别。外因是风湿所伤；内因是禀受父母的真阳不足。我曾见过一位士人，他的妻子生育了十多个男孩，都在出生后七日内死于脐风，没有一个存活。如果说只是外邪所伤，为什么偏偏伤害这一家的孩子？又难道没有哪一个孩子能避开吗？这就是内因显而易见的证据。凡是男子命门真阳不足的，右尺脉必然细涩无神，生子必定会有脐风。这是我观察详细、见识确凿，不是道听途说所能比的。至于外因引起的，发病多在二、三、四、五天之间，病生于六腑，所以可以治疗；内因引起的，一定发病在六七天之间，病生于五脏，所以不可治疗。以前，夏禹铸有预防脐风的秘诀，说出生三天到七天，看婴儿两眼眼角发黄，就一定会有脐风，却不知道禀赋浓厚的人，生下即满面红黄，那是吉色，误认为是脐风，危害不小，这种方法不准确。只有让乳母每天抚摸婴儿两侧乳房，如果乳内有一个小核，才是其征兆。然而乳内有核，发作脐风的固然很多，但也有不发脐风的，这种方法十有七八准确，也有两三分不准确。只要看小儿不时打喷嚏，更多啼哭，吮乳时口松，这才是真正的征兆，应当立即治疗。但是脐风的治疗，没有一成不变的方法可循，虽然有疏风攻下的方法，也不能解决紧急情况。唯独我异授的灯火疗法，无论脐风痉搐，以及凶险危重证候，用药不能挽回的，此火法可以救活，久经效验，我不肯轻易传授，因为看到儿科医生不懂火穴，往往错误使用，反而导致引动风邪，闭塞固着火毒，致使婴儿身热不退，火毒内攻，大多不能救治，所以不忍心隐瞒，全部披露出来，公之于世。世上的儿科医生治病，动不动就说剪风、截风。所谓“剪”，是邀击遏制的意思；所谓“截”，是堵塞的意思。用火功作用于中宫任脉运行的地方，岂不是堵塞邪气，而犯了“关门逐盗”的禁忌吗？不知道风邪在人身，善于运行变化，无形无声，想要除去它的危害，不如疏散条达让它出去，不让它久留于营卫经络就好了。就像张仲景治疗伤寒，确立汗、吐、下三法。邪气在表的，用汗法发散它；邪气在上的，用吐法涌越它；邪气深入体内的，用下法攻夺它。总是希望邪气尽除才停止，没听说过有邀击截断的做法。现在的儿科医生不仅不驱逐邪气，反而闭关绝险，阻断邪气去路，使邪气进不得，退不能，猖狂徘徊，想要它不倒戈相攻、斩关逆犯，是不可能的。这都是治疗者酿成的祸患，对邪气有什么可怪罪的呢？大凡邪气伤人，无不从三阳经进入；驱除的方法，也一定要让它从三阳经排出。所以这个火穴也只用于三阳经，目的是引导邪气出表，绝不使之入里。恭敬地绘制图说详述如下，并请大方之家指正。
The navel is the general aperture for wind pathogens and the cold gate of the five zang organs. Daoists refer to it as the Lower Dantian (Lower Elixir Field), the life stem of the human body. When a fetus is in the womb, its mouth and nose have not yet established respiration; it relies solely on the true breath at the navel, breathing in sync with the mother's respiration. Upon birth, when the infant cries out, qi connects through the mouth and nose, and the single breath of the fetal origin is no longer used. This qi resides within the navel, one inch and three fen deep, forming a hollow cavity. The left side is green, the right white, the upper red, the lower black, and the center yellow. The eight extraordinary vessels and nine orifices are connected here by longitude and latitude, serving as the pathway for the往来 of true breath and the meeting place of Kan and Li (Water and Fire). All practices of cultivating the immortal fetus are founded here, hence it is called the "Life Stem." Therefore, for newborns, the care of the navel is of utmost importance. When cutting the umbilical cord, one must be extremely cautious. If the cord is cut too short or bound loosely, external wind may invade the navel. Or, if moving the cord during bathing allows water to enter and cause sores, guest wind may enter due to deficiency, damaging the Kidney internally. The pathogen then transmits from the Kidney to the Liver, from the Liver to the Heart, from the Heart to the Spleen, and from the Spleen to the Lung, accumulating toxicity until it manifests as Umbilical Tetanus (Qi Feng). Symptoms include: red face and crying indicating Heart disease; slight twitching of hands and feet indicating Liver disease; blue lips, retracted mouth, and phlegm obstruction indicating Spleen disease; tight jaw indicating Kidney disease; incessant crying indicating Lung disease. If symptoms of the five zang organs appear only partially, it is treatable; if all appear, it is untreatable.
Among newborns, Umbilical Tetanus is considered a malignant condition. There are three types: Umbilical Tetanus, Locked Mouth, and Locked Belly. Although all are navel-related syndromes, their cold-heat nature differs, and practitioners should distinguish them carefully.
The first is Umbilical Tetanus. It occurs when, after cord cutting, water-dampness and wind-cold invade the navel and flow into the Heart and Spleen, causing abdominal distension, loose grip during suckling, excessive crying without feeding. In the early stage, fire therapy should be used promptly to disperse the pathogen. If it progresses to rapid breathing, loss of cry, exposed blue veins on the abdomen, or painful hernia, this indicates fetal toxin combined with wind-pathogen entering the zang organs. External fire therapy should be applied, and internally, Zhimi Qiqi Decoction (Seven-Qi Decoction for Pointing Confusion) should be taken. If the navel becomes blue and swollen, the mouth cannot open, the jaw is tightly shut, white foam is spat out, and the fingernails turn blue-black, these are signs of untreatable conditions.
The second is Locked Mouth. Symptoms include closed eyes, locked jaw, diminishing cry, flesh-like granules on the tongue resembling millet grains, inability to suckle, spitting white foam, and blockage of urination and defecation. In such cases, first check for small white spots on the palate. If present, gently scrape them with a fingernail. Then, decoct Mugwort Root (Muxiang) and White Cardamom Seed (Baikouren), each 5 fen, and administer Hangxie Dan dissolved in the decoction. This promotes bowel movement and organ function, allowing qi to smooth out and the condition to heal spontaneously.
The third is Locked Belly. It results from excessive heat-toxin in the womb blocking the anus, causing constipation. Urgently have a woman rinse her mouth with warm water and suckle the infant's anterior and posterior chest, below the navel, and the palms of hands and soles of feet—seven areas in total—for four or five times. Externally, grind Calomel (Qingfen) 5 fen into powder, mix with a little honey, and administer with warm water, aiming for bowel evacuation. If still blocked, take a scallion white piece 3-4 cun long, lubricate with oil, and gently insert it about 2 cun into the rectum, aiming for relief. If there is no passage by the seventh day, death ensues.
Ancient discussions on Umbilical Tetanus attribute it solely to water-dampness and wind-cold. I believe this explanation is incomplete. Umbilical Tetanus has both internal and external causes, distinguishing between treatable and untreatable cases. The external cause is injury from wind-dampness; the internal cause is insufficiency of the True Yang inherited from parents. I once observed a scholar whose wife bore over ten sons, all dying of Umbilical Tetanus within seven days, none surviving. If it were merely external pathogens, why would they exclusively harm this family's children? Why would not some escape? This clearly demonstrates the internal cause. For men with insufficient True Yang of the Mingmen (Gate of Life), the pulse at the right Chi position will be fine, choppy, and spiritless; their offspring will inevitably suffer from Umbilical Tetanus. My observations are detailed and accurate, unlike hearsay. External causes typically manifest between the second and fifth days, affecting the fu organs, thus being treatable. Internal causes typically manifest between the sixth and seventh days, affecting the zang organs, thus being untreatable. Previously, Xia Yuzhu offered a secret for preventing Umbilical Tetanus: observe the inner corners of the eyes on the third to seventh day; yellowing indicates impending tetanus. However, infants with strong constitution may have a red-yellow complexion immediately after birth, which is auspicious, not tetanus. Mistaking this leads to significant harm; this method is inaccurate. A better sign is for the lactating mother to massage the infant's breasts daily; a small lump inside indicates the syndrome. While many with lumps develop tetanus, some do not; this method is 70-80% accurate but not infallible. The true signs are frequent sneezing, excessive crying, and loose grip during suckling. Treatment should begin immediately. However, there is no fixed formula for treating Umbilical Tetanus. Methods like dispersing wind and purging downward cannot address emergencies. Only my uniquely transmitted Fire-Lamp Therapy can save lives in cases of tetanic convulsions or critical conditions where medicine fails. It has proven effective over time. I was reluctant to share it because I saw pediatricians misuse fire points, inadvertently stirring wind pathogens and trapping fire-toxin, leading to persistent fever and internal attack by fire-toxin, often resulting in death. Thus, I reveal it publicly. Pediatricians often speak of "cutting wind" or "blocking wind." "Cutting" implies intercepting and restraining; "blocking" implies sealing off. Applying fire therapy to the Ren Mai (Conception Vessel) in the central palace seems to block the pathogen, violating the principle of "locking the door to chase away thieves." Wind pathogens in the body are agile and changeable, formless and soundless. To eliminate them, one must disperse and guide them out, preventing them from lingering in the Ying and Wei levels and meridians. Zhang Zhongjing treated Cold Damage using sweating, vomiting, and purging methods. Pathogens on the exterior are dispersed via sweating; those above are expelled via vomiting; those deeply interior are removed via purging. The goal is always to exhaust the pathogen, never to intercept or block it. Modern pediatricians not only fail to expel pathogens but also close the gates, blocking their exit, trapping them so they cannot advance or retreat, leading to chaotic rebellion. This disaster is caused by the practitioner, not the pathogen. Pathogens enter via the Three Yang channels; they must be expelled via the Three Yang channels. Therefore, this fire-point therapy is applicable only to the Three Yang channels, aiming to draw pathogens out to the exterior, never letting them enter the interior. Detailed diagrams follow, and I respectfully request correction from experts.
