Pediatric Piān Fēng (Hemiplegic Wind) is a syndrome of the Shàoyáng (Lesser Yang) and Juéyīn (Terminal Yin) meridians, specifically involving the Liver and Gallbladder. Kǒu Jìn (Lockjaw) occurs when excessive Wind-Wood pathogenic factor overacts on Spleen-Earth, causing dryness and tension in the tendons. Although Dryness governs contraction and rigidity, whether affecting the left or right side, the etiology remains consistent. If Qi deficiency in the Foot-Yangming Stomach Meridian allows Wind pathogen to invade, resulting in unilateral tendon tension, it belongs to internal causes. If Spleen and Lung deficiency leads to loose interstices allowing external pathogens to invade, or if post-emesis/diarrhea depletes body fluids failing to nourish the Liver, causing facial deviation, these all fall under insufficient Liver Blood generating internal Fire that produces Wind. The treatment principle should be to nourish Kidney Water to benefit Liver Blood and strengthen Spleen Earth. For Wind stirring due to Spleen-Stomach deficiency, use Yì Gōng Sǎn (Benefiting the Working Powder) with Cháihú (Bupleuri Radix) and Gōuténg Gōu (Uncariae Ramulus cum Uncis). For Liver-Lung deficiency with external pathogen invasion, use Gōuténg Yǐn (Uncaria Decoction). If accompanied by eyes tightly closed and looking upward, alternating chills and fever, dribbling urination, bluish complexion, and hypochondriac distension, these are primary diseases of the Liver Meridian. If accompanied by facial deviation, abdominal pain, poor appetite, eyelid edema, bluish-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 accordingly. Adhering rigidly to observed symptoms and indiscriminately administering wind-dispelling drugs will instead result in complicated disorders.

Jiǎo Gōng Fǎn Zhāng (Opisthotonos) is synonymous with Jìng Bìng (Spasm Disease). It results from empty and sparse meridians invaded by deficient Wind, leading to tendon tension. Alternatively, fright or food stagnation may confine the Liver and Spleen, internally stirring deficient Wind, both capable of causing this condition. If the body arches backward rigidly with fever but without convulsions, it indicates Wind damaging the Taiyang (Greater Yang) meridian; treat with Rénshēn Bàidú Sǎn (Ginseng Powder for Overcoming Toxins) or Xiǎo Xùmíng Tāng (Minor Xu-Ming Decoction). Due to fright causing fixed gaze, yawning, sudden neck stiffness and dizziness, it is an internal Wood-Wind disease; treat with Gōuténg Sǎn (Uncaria Powder). Due to violent anger stirring Liver-Fire, treat with Xiè Qīng Wán (Draining Blue Pill). If symptoms worsen after taking previous prescriptions, it indicates the pathogen has departed but Spleen Qi is deficient; treat with Yì Gōng Sǎn plus Chuānxiōng (Ligustici Chuanxiong Rhizoma) and Dāngguī (Angelicae Sinensis Radix) to tonify. If constitutionally weak in Qi and Blood, or after using attacking/draining agents, presenting with hand grasping at clothing, teeth grinding, and yawning, this indicates severe Lung Meridian deficiency; combine with Liù Jūnzǐ Tān (Six Gentlemen Decoction) and Dìhuáng Wán (Rehmannia Pill) to tonify.

Qian Yi stated: Pediatric Jí Jīng (Acute Convulsion) arises from hearing loud noises or being frightened, triggering convulsions which cease leaving the child normal. This heat originates in the Heart, manifesting as fever, red face, thirst, hot breath, and yellow-red urine and stool; severe cases involve convulsions. Generally, excessive heat generates wind, where Yang is excess and Yin is deficient. The Classics state: Heat generates wind; wind stirs phlegm. Phlegm-heat lodges between the Heart and Diaphragm, with wind and fire battling, thus initiating convulsions. Use Bàolóng Wán (Dragon-Holding Pill) and Xiè Qīng Wán to clear phlegm-heat; do not use Bàdòu (Croton Seed). Lou Quanshan stated: Acute convulsion belongs to Excess patterns of Wood, Fire, and Earth. Wood excess causes forceful convulsions and upward eye deviation; Fire excess causes frequent blinking; Earth excess causes fever, red face, without vomiting/diarrhea, lethargy with closed eyes. Treatment should be cooling and draining, using Lìjīng Wán (Calming Convulsion Pill), etc. Some arise from fright, presenting with tight jaw, high fever, salivary flooding, wandering eyes, opisthotonos, tremors, twitching of lips/mouth/eyebrows, hot breath, red cheeks/lips, constipation, and floating-rapid-tight pulse. This indicates internal excess heat with external wind pathogen; one should intercept wind and stop convulsions. If phlegm-heat persists, mild purgation is still appropriate. Once phlegm-heat is drained, urgently regulate Spleen Qi. This is because Liver-Gallbladder blood deficiency allows Fire to stir Wind; as Wind generates, Yin-Blood scatters further and Yin-Fire flares. If repeated use of wind-dispelling, phlegm-resolving, fire-draining, and acrid-warm dispersing agents fails, recognize it as Spleen deficiency and blood damage; urgently use Liù Jūnzǐ Tān to tonify Spleen and Stomach, otherwise it will inevitably transform into Màn Jīng (Chronic Convulsion). In acute convulsion, if the infant's eyes roll back, legs jerk and kick, suddenly cries out and vomits preventing medicine intake, and nasal insufflation yields no sneeze, it is untreatable.
