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.
