总括：夜啼的四种证候中，惊风引起的表现为：见灯光流泪、心烦发热；面目及脸颊发青、脐下疼痛；面色黧黑、大声哭闹，这是神志受扰（神干）所致。
脉法：观察小儿虎口指纹，若指纹隐伏不见，呈现如尘土般的颜色，这是客忤（外邪侵袭）或鬼祟之脉，必然导致夜啼。
盘肠气发作时，先出现腰部弯曲，无泪叫啼、眼睛干涩哭泣，口张脚冷、上唇发乌，额头汗出如珠。
《内经》说：心藏神，神志安宁则脏腑调和。小儿白天精神安定，夜晚安稳睡眠。如果心热惊热，或者风寒之邪乘虚而入，则精神不能安定，从而导致夜间啼哭不止。
心热证：见到灯光啼哭更甚，面色红、多眼泪，没有灯光时稍微平息。因为火是阳物，心热遇到火，两阳相搏，所以一有灯就啼哭厉害，因此《内经》说“火痰风生”就是这个道理。治疗宜凉心安神，使用三解散（参见惊风章节，去掉人参，用薄荷汤送服）。
惊热证：因穿衣盖被太厚，或在热处久坐，导致烦闷，邪热攻心。心藏神，神安则和，神乱则惊，治疗方法是退热镇心，自然就能安宁，使用牛蒡散、抱龙丸。
有的患儿在黄昏后到半夜时分，哭多啼少；有的啼声不停直到天明，这是胎中受寒所致。遇夜则阴盛阳微，所以腰部弯曲、额头出汗，眼中无泪，面色莹白而脸颊发青，趴着啼哭，这是腹痛内吊的症状，名为寒疝，治疗方法是去除宿冷、温补下焦，使用白芍药汤及钩藤丸。
误触禁忌而夜啼者，面色紫黑，气郁像发怒一样，呼喊时好像恐惧，睡中惊惕，两手抱着母亲，大哭不休。这是误触恶祟神祗，眼睛看到了什么，嘴巴不能说出来的缘故！古语说：“忽然两手形状看不见，定知唐突了恶神明。”知道这种病症的人，适宜看双手指纹都隐伏不见，治疗方法先解表，使用百解散，其次驱邪镇心，使用苏合香丸、抱龙丸。
啼与哭也有区别，啼而不哭是痛，所以直声来往而无泪；哭而不啼是惊，所以连声不绝而多泪。又说：啼而不哭是烦，哭而不啼是燥。
面色青、眼白发黄，腰部弯曲而啼，抚摸腹部觉得冷，这一定是感寒肚疼。
面色红、心烦躁，小便赤涩，口中及腹部都热，间或有汗，仰身而啼，这是热症。
又有乳汁送到嘴边即啼哭，身体头额皆热，必须查看口腔内无疮，必然是喉舌肿痛。

General Overview: Among the four syndromes of night crying, the one caused by Wind-Convulsion (Jing Feng) presents with tearing upon seeing light, mental restlessness, and heat; bluish discoloration of the face, cheeks, and below the umbilicus; dark complexion, loud crying, which is due to disturbance of the Spirit (Shen Gan).
Pulse Diagnosis: Observing the fingerprint on the tiger's mouth (Hu Kou), if the fingerprint is invisible and appears dusty in color, this indicates an invasion by external pathogens (Ke Wu) or malevolent spirits, which inevitably leads to night crying.
When Pan Chang Qi (Intestinal Colic) occurs, it first manifests as curvature of the waist, crying without tears, dry eyes, open mouth, cold feet, blackish upper lip, and beads of sweat flowing from the forehead.
The *Nei Jing* states: The Heart stores the Spirit (Shen); when the Spirit is peaceful, the Zang organs are harmonious. Infants have peaceful spirits during the day and sleep soundly at night. If there is Heat in the Heart or Convulsive Heat, or if Cold-Wind pathogens invade, the spirit cannot remain stable, leading to incessant night crying.
Heart Heat Syndrome: Crying intensifies upon seeing light, with a red face and abundant tears; it subsides slightly in the absence of light. Fire is a Yang entity; when Heart Heat encounters Fire, two Yangs clash, causing intense crying at the sight of a lamp. Thus, the *Classic* says "Fire generates Phlegm and Wind," which explains this mechanism. Treatment should cool the Heart and calm the Spirit using San Jie San (see Wind-Convulsion section, remove Ginseng Radix et Rhizoma [Renshen], administer with Mint Decoction [Bohe Tang]).
Convulsive Heat Syndrome: Caused by wearing too many clothes or sitting for long periods in hot places, resulting in stuffiness and malignant Heat attacking the Heart. The Heart stores the Spirit; peace brings harmony, while disorder brings convulsion. The treatment method is to reduce Heat and settle the Heart, after which peace will naturally return, using Niu Bang San (Burdock Powder) and Bao Long Wan (Dragon-Holding Pill).
Some infants cry more than they wail from dusk until midnight; others cry continuously until dawn. This is due to Cold contracted in the womb. At night, Yin prevails and Yang is weak, hence the curved waist, sweating forehead, tearless eyes, pale face with bluish cheeks, prone position while crying. This is a symptom of abdominal pain drawing inward, named Han Shan (Cold Hernia). The treatment method is to eliminate residual Cold and warm the Lower Jiao, using Bai Shao Yao Tang (White Peony Decoction) and Gou Teng Wan (Uncaria Pill).
Night crying due to violating taboos presents with a purplish-black complexion, Qi stagnation resembling anger, cries sounding fearful, startle during sleep, holding the mother tightly, and unceasing loud crying. This is due to offending malevolent spirits; the eyes saw something but the mouth cannot speak of it! An ancient saying goes: "If the hands suddenly appear shapeless, know that you have offended evil deities." For such cases, where both finger fingerprints are hidden and invisible, the treatment method is first to release the Exterior using Bai Jie San (Hundred-Resolving Powder), then to expel Evil and settle the Heart using Su He Xiang Wan (Styrax Pill) and Bao Long Wan (Dragon-Holding Pill).
Wailing (Ti) and Crying (Ku) also differ. Wailing without crying indicates Pain, characterized by direct sounds without tears; Crying without wailing indicates Startle, characterized by continuous sounds with abundant tears. It is also said: Wailing without crying is Restlessness (Fan); Crying without wailing is Dryness/Irritability (Zao).
Bluish face, white sclera, curved waist while crying, and cold abdomen upon palpation indicate Cold-induced abdominal pain.
Red face, mental irritability, dark and scanty urination, heat in the mouth and abdomen, occasional sweating, and supine position while crying indicate a Heat Syndrome.
Another case involves crying as soon as milk reaches the infant's mouth, with heat in the body, head, and forehead. One must check that there are no sores in the mouth; otherwise, it is必定 swelling and pain of the throat and tongue.
