陈飞霞曰∶平素产子有脐风，则胎胎不爽。于产下第二日，勿待其发，先以此火散之，百不一失。胎儿生下，
多啼不乳，喷嚏呵欠，吮乳口松，即是脐风将作，急以此火治之。凡儿病面青黑，扭项摇头，仰身擦面，或眼青
怒视，或左右斜视，或上下窜视，或两目连眨，或头项牵强，卷舌露睛，嘘风撮口，啼哭咬人，或手如数物、或
两手牵引，或两足跳掣，忽扰忽乱，失张矢志，但觉精神与常有异者，由从前表里不清，将欲作痉，此火至妙。伤
寒已痉，角弓反张，眼目斜视，左右搐搦，但中恶容忤、痫证与食填太阴，及一切风闭、火闭、痰闭、气闭，乍
然卒死者，此火最神。食伤脾骨，肚大筋青，于端午日午时，用全身灯火，后于青筋开叉处，以火截之。一叉一
点，其肚自消。风寒痰气闭塞之症，此火实有神功。凡用灯火既完，候儿啼哭已定，即用金粟丹半丸，（《集成》
未详）姜汤化服。服后以衣裹之，蒙其头面，令之安卧片时，以复其神志，其病如失。小儿四时感冒伤寒汗出，
大小便调，唇舌如常，口不作渴，此表病轻症也，疏散之则愈，忌用灯火。小儿邪已入里，身热面赤口渴，大小便
闭，唇焦舌紧眼红，或手足心热，夜热烦焦，舌上黄苔，扬手掷足，掀衣掀被，此里症内热，清利自愈，切忌灯
火。小儿大病久病，身体怯弱，面目青黄，唇舌自莹，摇头斜视，昏睡露眼，形
骸消瘦，声息轻微，自汗盗汗，或一切呕吐泄痢，痘麻疮痈，久咳久疟，失血之后，精神疲倦，乳食减少，指纹沉
细，六脉无神。此皆极虚之症，切忌火攻，虑其升散故也。一切久热消渴疳症，形骸黑瘦，毛发焦枯，由阴枯血
弱虚热所为，切忌灯火。
涂蔚生曰∶婴儿之用灯火，犹伤寒之用麻姜附，非病为阴寒，固不可用，而非病至危急，尤不可用。故除脐风
而外用者颇少。然亦以夏禹铸之脐风灯火为简妥。医者须于此等界限认清，方不至误儿性命。至其所谓宜灯火之客忤
症，与火痰闭症，则未免失之过当。盖客忤为一种秽恶毒厉之气，多系热亢，只宜清解；而火痰闭症，则又只宜
清利者也。
陈飞霞说：平时生产时若发生过脐风（新生儿破伤风），则胎儿往往体质不佳。在婴儿出生的第二天，不要等到病症发作，先用这种灯火疗法来预防，几乎不会失手。婴儿出生后，如果多啼哭而不吃奶，打喷嚏、打哈欠，吸吮乳汁时口松无力，这就是脐风即将发作的征兆，应立即用这种灯火疗法治疗。凡是婴儿患病出现面色青黑，扭动脖子摇头，身体后仰擦脸，或者眼睛发青愤怒地直视，或向左右斜视，或上下窜动注视，或双眼连续眨眼，或头项僵硬牵强，卷舌露睛，像吹气一样撮口，啼哭咬人，或者手像数东西一样抽动，或两手牵引抖动，或两脚跳跃抽搐，忽而扰乱忽而混乱，失去常态志向，只要觉得精神状态与平常不同，这是由于从前表里不清，将要发生痉挛，这种灯火疗法极为奇妙。对于伤寒已经发生痉挛，角弓反张，眼目斜视，左右抽搐的人，以及中恶容忤、痫证和食填太阴（食物停滞导致脾胃功能严重受阻），以及一切风闭、火闭、痰闭、气闭导致的突然猝死，这种灯火疗法最为神奇。如果是饮食损伤脾骨，导致肚子大筋脉显露，在端午日中午时分，用全身灯火疗法，然后在青色筋脉分叉的地方，用灯火截断治疗。一个分叉点一个灯，肚子自然会消退。对于风寒痰气闭塞的症状，这种灯火确实有神奇功效。凡是用完灯火之后，等婴儿啼哭平静后，立即服用半丸金粟丹（《医宗集成》未详细说明配方），用姜汤化开服用。服药后用衣服包裹，蒙住头面，让其安静躺卧片刻，以恢复神志，病就像消失了一样。小儿四季感冒伤寒出汗，大小便正常，嘴唇舌头如常，口不渴，这是表证轻症，疏散即可痊愈，忌用灯火。小儿邪气已入里，身体发热面赤口渴，大小便闭塞，嘴唇焦裂舌头紧绷眼睛红，或者手足心热，夜间发热烦躁，舌上有黄苔，扬手掷足，掀衣掀被，这是里证内热，清利自愈，切忌使用灯火。小儿大病久病，身体怯弱，面目青黄，嘴唇舌头润泽，摇头斜视，昏睡露眼，形体消瘦，声音气息轻微，自汗盗汗，或一切呕吐泄痢，痘疹麻疮痈肿，久咳久疟，失血之后，精神疲倦，乳食减少，指纹沉细，六脉无神。这些都是极虚之症，切忌用火攻，担心其升散耗气。一切久热消渴疳症（慢性消耗性疾病），形体黑瘦，毛发焦枯，由阴枯血弱虚热所致，切忌使用灯火。
涂蔚生说：婴儿使用灯火疗法，就像伤寒治疗中使用麻黄、生姜、附子一样，如果不是阴寒病症，固然不可用；而且如果不是病情危急，尤其不可用。所以除了脐风之外，使用其他情况颇为少见。然而也以夏禹铸的脐风灯火方为简便稳妥。医生必须认清这些界限，才不会误害婴儿性命。至于他所说的适宜用灯火的客忤症（因惊吓或秽气引起的病症）和火痰闭症，则未免失之过当。因为客忤是一种秽恶毒厉之气，多属于热亢盛，只宜清解；而火痰闭症，则只宜清利。
Chen Feixia stated: If a mother has experienced umbilical wind (neonatal tetanus) during previous deliveries, the fetus is often constitutionally weak. On the second day after birth, do not wait for symptoms to appear; instead, apply this lamp-fire therapy prophylactically, with nearly 100% efficacy. After birth, if the infant cries frequently but refuses to nurse, sneezes, yawns, or shows loose jaw muscles when attempting to suckle, these are signs that umbilical wind is about to manifest. Immediate application of this lamp-fire therapy is required. For infants presenting with dark blue-black facial complexion, neck twisting and head shaking, body arching backward while rubbing against surfaces, glaring eyes with a blue tint, lateral or vertical gaze deviations, continuous blinking, stiff neck and head, curled tongue with exposed eyes, puckered mouth as if blowing wind, crying and biting, hand movements resembling counting, arm traction or tremors, leg jumping or spasms, erratic behavior, loss of normal demeanor, or any deviation in mental state from the usual, these indicate unclear exterior-interior dynamics preceding convulsions. In such cases, this lamp-fire therapy is extremely effective. For conditions where cold damage has already led to convulsions, opisthotonos (arched back), lateral eye deviation, and bilateral spasms, as well as sudden death due to evil shock, epilepsy, food stagnation affecting the Taiyin spleen/stomach, or various obstructions caused by wind, fire, phlegm, or qi, this lamp-fire therapy is miraculous. For dietary injury to the spleen bones resulting in abdominal distension and visible subcutaneous veins, on the noon hour of the Dragon Boat Festival, apply full-body lamp-fire therapy, then treat at the branching points of the blue veins with lamp-fire. One branch treated with one point will cause the abdominal distension to resolve spontaneously. This therapy holds miraculous power for symptoms caused by obstruction of wind-cold and phlegm-qi. After completing lamp-fire therapy, once the infant's crying subsides, administer half a pill of Jin Su Dan (Golden Millet Pill, detailed formula unspecified in *Yi Zong Ji Cheng*) dissolved in ginger decoction. Wrap the infant in clothing, cover the head and face, and allow them to rest quietly for a moment to restore their spirit and consciousness, after which the illness will seem to vanish. For children with mild exterior syndromes due to seasonal cold damage or common cold, characterized by sweating, normal bowel and bladder functions, normal lips and tongue, and no thirst, dispersing and diffusing treatments will lead to recovery; lamp-fire therapy is contraindicated. For children with pathogenic factors entering the interior, presenting with fever, red face, thirst, constipation, dry cracked lips, tight tongue, red eyes, hot palms and soles, nighttime fever and irritability, yellow tongue coating, flailing limbs, and kicking off covers, these are interior heat syndromes that heal with clearing and draining methods; lamp-fire therapy is strictly contraindicated. For children suffering from severe or chronic illnesses, presenting with physical frailty, bluish-yellow complexion, moist lips and tongue, head shaking, lateral gaze, drowsiness with exposed eyes, emaciation, faint voice and breath, spontaneous or night sweats, vomiting, diarrhea, dysentery, smallpox/measles/rashes/abscesses, chronic cough, chronic malaria, post-hemorrhagic fatigue, listlessness, reduced milk/food intake, deep and fine fingerprint pulse, and spiritless six pulses, these are extreme deficiency syndromes. Lamp-fire therapy is strictly contraindicated because it risks ascending and dispersing vital energy. For all chronic fevers, wasting-thirst syndromes, and malnutrition syndromes characterized by dark emaciation and brittle hair, caused by yin exhaustion, blood weakness, and deficient heat, lamp-fire therapy is strictly contraindicated.
Tu Weisheng stated: The use of lamp-fire therapy in infants is analogous to the use of Ephedrae Herba (Mahuang), Zingiberis Rhizoma (Shengjiang), and Aconiti Lateralis Radix Praeparata (Fuzi) in treating cold damage. It should not be used unless the disease is of yin-cold nature, and especially not unless the condition is critical. Therefore, its use outside of umbilical wind is quite rare. However, the Umbilical Wind Lamp-Fire prescription by Xia Yuzhu is considered simple and appropriate. Physicians must clearly recognize these boundaries to avoid harming the infant's life. Regarding his claim that Ke Wu syndrome (illness caused by fright or foul air) and Fire-Phlegm Obstruction syndrome are suitable for lamp-fire therapy, this is somewhat excessive. Ke Wu is caused by foul and toxic qi, often associated with hyperactive heat, and should only be treated with clearing and resolving methods. Fire-Phlegm Obstruction syndrome should also be treated with clearing and draining methods.
