小儿偏风病，属于少阳经和厥阴经（肝胆二经受邪）的病症。口噤是指筋脉拘急，这是由于风木之气过盛而克制脾土，进而克制水湿，导致筋脉过于干燥。然而，燥金之气主收敛且劲切，故有此表现。又说：风邪致病，善于游走且变化迅速，症状可能出现在身体左侧或右侧，其病因本质是一样的。治疗必须审慎辨证后用药。如果是足阳明胃经气虚，风邪乘虚而入，导致一侧筋脉拘急，这属于外因所致。如果是足厥阴肝经的风热之邪侵犯脾土，导致一侧筋脉拘急，这属于内因所致。如果是脾肺虚弱，腠理（皮肤毛孔及肌肉间隙）不致密，外邪乘虚而入；或者服用金石类药物耗损了肝血；或者在呕吐腹泻之后，体内津液亡失不能滋养肝木，从而导致口眼歪斜，或者半身不遂，这些症状都属于肝血不足、肝火生风所致，适宜采用滋补肾水、滋养肝血、壮实脾土的方法治疗。
治疗方法：脾胃虚弱而动风者，使用异功散加柴胡、钩藤钩。脾肺虚弱而受外邪侵袭者，使用钩藤饮。肝火旺盛、血液枯燥者，使用六味地黄丸。津液不足者，使用白术散。如果兼有眼睛紧闭上视、寒热往来、小便淋漓不畅、面色青白、两胁胀痛等症状，这都是肝经的本脏病变。如果出现嘴唇口角歪斜、腹痛、食欲不振、眼睑浮肿、面色青黄、肢体倦怠等症状，这都是肝木克制脾土的病症，应当审察五脏之间的相克关系来主治。如果固执于表面症状，一概投用祛风药物，反而会造成坏证的情况是有的。
治验案例：
有一个小儿出现口眼歪斜，面色有时发青有时发红，这是肝心风火之邪侵犯脾土所致。早晨服用柴胡清肝散，晚上服用异功散加钩藤钩，从而痊愈。当时有患同样病症的人，服用祛风导痰的药物，都不能治愈。
另一个小儿在痢疾后出现上述病症并发搐搦。面色萎黄，肢体倦怠，这是元气虚弱且被攻伐过多所致。我使用补中益气汤加钩藤钩子服用，逐渐痊愈。后来因为乳母七情饮食调理不当，或者小儿乳食过多，前症再次发作。服用补中益气汤、五味异功散后见效。

Pediatric hemiplegia with facial deviation (Pian Feng) belongs to the syndromes of the Shaoyang and Jueyin meridians (pathogens affecting the Liver and Gallbladder channels). Trismus (Jin) refers to tendon tension, caused by excessive Wind-Wood qi overacting on Spleen-Earth, thereby overcoming Water-Dampness, resulting in excessive dryness of the tendons. However, Dryness-Metal governs contraction and rigidity, hence this manifestation. It is also said: Wind pathogens are prone to migration and rapid changes; symptoms may appear on the left or right side, yet the underlying etiology remains the same. Treatment requires careful differentiation before administering medication. If Qi deficiency in the Foot-Yangming Stomach channel allows Wind pathogens to invade, causing unilateral tendon tension, it is classified as an external cause. If Wind-Heat from the Foot-Jueyin Liver channel invades the Spleen, causing unilateral tendon tension, it is classified as an internal cause. If Spleen and Lung Qi are deficient, and the Couli (pores and interstitial spaces) are not dense, allowing external pathogens to invade; or if mineral drugs have consumed Liver Blood; or if post-emetic/diarrheal fluid loss fails to nourish the Liver Wood, leading to facial deviation or hemiplegia, these symptoms all belong to insufficient Liver Blood and Wind generated by Liver Fire. The appropriate treatment is to nourish Kidney Water, tonify Liver Blood, and strengthen Spleen Earth.
Treatment methods: For Wind movement due to Spleen-Stomach deficiency, use Yigong San (Isolated Efficacy Powder) with Chai Hu (Bupleuri Radix) and Gou Teng Gou (Uncariae Ramulus cum Uncis). For Spleen-Lung deficiency with external pathogen invasion, use Gou Teng Yin (Uncaria Decoction). For Liver Fire and blood dryness, use Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill). For fluid insufficiency, use Baizhu San (Atractylodes Powder). If accompanied by eyes tightly closed and looking upward, alternating chills and fever, dribbling urination, pale-green complexion, and distending pain in the hypochondrium, these are primary diseases of the Liver channel. If accompanied by lip and mouth deviation, abdominal pain, poor appetite, eyelid edema, green-yellow complexion, and limb fatigue, these are syndromes of Liver Wood overacting on Spleen Earth; one must examine the mutual overcoming relationships among the Five Zang organs to treat them. If one stubbornly adheres to visible symptoms and indiscriminately administers Wind-dispelling herbs, adverse outcomes may occur.
Clinical Cases:
One pediatric patient presented with facial deviation, with a complexion that was sometimes green and sometimes red. This indicated Liver and Heart Wind-Fire invading the Spleen. In the morning, Chai Hu Qing Gan San (Bupleurum Liver-Clearing Powder) was administered; in the evening, Yigong San with Gou Teng Gou was given, resulting in recovery. At that time, other patients with similar symptoms who took Wind-dispelling and phlegm-resolving medicines failed to recover.
Another pediatric patient developed convulsions following dysentery. The complexion was sallow, and limbs were fatigued, indicating deficient Yuan Qi (Primordial Qi) and excessive depletion. I administered Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Gou Teng Gou, leading to gradual recovery. Later, due to improper emotional regulation and diet by the wet nurse, or excessive milk/food intake by the infant, the previous symptoms recurred. Administration of Buzhong Yiqi Tang and Wuwei Yigong San proved effective.
Qian's Quanxie San (Scorpion Powder), treating facial deviation, abnormal speech, and hemiplegia caused by Wind-stroke (Jing Feng):
Quan Xie (Scorpio, detoxified and fried), Jiang Can (Bombyx Batryticatus, straight ones, fried), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Huang Qin (Scutellariae Radix), Gan Cao (Glycyrrhizae Radix et Rhizoma), Gui Zhi (Cinnamomi Ramulus), Chi Shao (Paeoniae Radix Rubra), Ma Huang (Ephedrae Herba, nodes removed, each 2 qian), Tian Ma (Gastrodiae Rhizoma, 6 qian), Tian Nan Xing (Arisaematis Rhizoma, umbilicus removed, 2 qian).
Grind into powder. Take 2–3 qian per dose, with 5 slices of fresh ginger, decocted in water.
Weifeng Tang (Stomach Wind Decoction), treating Wind-Cold invading the intestines and stomach due to deficiency, causing undigested food and watery diarrhea, as well as intestinal-rectal damp-toxin manifesting as stool resembling bean curd dregs or blood clots, occurring day and night:
Ren Shen (Ginseng Radix), Baifu Ling (Poria), Xiong (Chuan Xiong), Gui (Gui Zhi), Dang Gui (Angelicae Sinensis Radix), Bai Shao (Paeoniae Radix Alba), Baizhu (Atractylodis Macrocephalae Rhizoma, equal parts).
Take 2 qian of the powder per dose, decocted with a few grains of millet, taken before meals.
