According to *Maijue Qimeng* (Enlightenment on Pulse Diagnosis), a rapid and hurried pulse in children indicates deficiency-type fright (*Xu Jing*). According to *Zhizhi Fang*, a floating, rapid, full, or tight pulse indicates acute convulsion (*Ji Jing Feng*), while a deep, slow, scattered, or slack pulse indicates chronic convulsion (*Man Jing Feng*).

A blue-purple coloration of the finger vein pattern at the tiger's mouth (the radial aspect of the index finger) indicates convulsion due to fright. A red color indicates mild wind-heat; a crimson color indicates intense wind-heat; a purple color indicates fright-heat; a green color indicates fright with food accumulation. If the pattern is green with pale purple, extending and retracting freely, it indicates chronic convulsion. If green and purple are equal, indicating both fright and food accumulation as well as wind-heat, it indicates acute convulsion. If purple, green, or black threads are faintly mixed, appearing as if emerging but not fully coming out, it indicates chronic spleen wind (*Man Pi Feng*). If the pattern curves inward toward the palm, it is a favorable sign (*Shun*); if it extends outward, it is an unfavorable sign (*Ni*).

**Medication Principles for the Four Syndromes of Convulsion: Phlegm, Heat, Fright, and Wind**

When heat exists in a child's body, excessive heat generates phlegm; excessive phlegm generates fright; excessive fright generates wind; excessive wind triggers spasms. Severe spasms lead to lockjaw, and extreme cases result in opisthotonos (arched back), head retraction, and upward gazing. When saliva and phlegm are congested, the jaw is tight. Extreme wind-heat blocks the meridians, causing spasms, jerking, and phlegm congestion. Stagnation and confusion in the stomach region, unconsciousness, and the pathogen entering the *Zhongwan* (CV12) area manifest as curled hands and feet. This occurs because all orifices are blocked and the hundred vessels are stagnant. Some recover through clearing heat, some through resolving phlegm, some through calming fright, and some through opening orifices. All these treatments are based on the specific syndrome. One must thoroughly investigate the root cause of the disease. If the pathology lies in heat, do not indiscriminately treat phlegm; if it lies in fright, do not indiscriminately treat wind; if it lies in phlegm, do not indiscriminately treat fright; if it lies in wind, do not indiscriminately treat spasms. Regarding treatment methods: if the pathology is in fright caused by phlegm-heat, one should only clear heat and resolve phlegm, and the fright will subside naturally. If the pathology is in wind caused by fright, one should only promote the resolution of fright and resolve phlegm, and the wind will disperse naturally. If the pathology is in phlegm with urgent salivation, one must clear heat and resolve phlegm. If spasms persist, one must use methods to arrest wind and calm fright. This represents flexible and adaptive treatment.

**Distinguishing Three Etiologies for Treating Convulsion**

Qian Yi stated: Children's convulsions may arise after contracting wind-cold. Symptoms include hot breath, yawning, restlessness, and trembling limbs. Treatment requires dispersing the exterior, primarily using *Daqing Gao* (Great Green Ointment). Children are inherently timid and prone to this condition. If arising after dietary injury, symptoms include mild fever, excessive sleep, vomiting, loss of appetite, and subsequent convulsions. One must first stop the convulsions; after they subside, administer *Baibing Zi* (White Pill) to purge the accumulation, followed by *Anshen Wan* (Calming Spirit Pill). Only exanthematous diseases can trigger convulsions due to the struggle between wind and fire. Treatment should involve purging the heart and liver and tonifying the mother organ (lung). *Leicui* states that for convulsions caused by wind-cold in children, similar to adults, one must distinguish between sweating and non-sweating presentations, differentiating yin and yang syndromes, and use *Daqing Gao* or Zhang Zhongjing's *Xiaoxuming Tang* (Minor Continuation of Life Decoction) to vent the pathogen. Dietary injury causing convulsions refers to sudden spasms without other causes, resulting from overeating damaging the spleen and stomach. Symptoms include lethargy, vomiting, and anorexia. Since the spleen and stomach are deficient, liver wind is drawn forth, triggering convulsions. First, stabilize the convulsions by adding *Qianghuo* (Notopterygii Rhizoma) and *Fangfeng* (Saposhnikoviae Radix) decocted to deliver *Xieqing Wan* (Draining Green Pill). Later, use *Baibing Zi* to purge food stagnation, gradually switching to *Tiaozhong Wan* (Regulating Middle Pill) and *Yigong San* (Extraordinary Power Powder) to nourish qi. Convulsions triggered by macules and papules occur because rashes are generated by spleen deficiency; spleen deficiency allows liver wood to overcome earth. Heat strikes, disturbing the heart spirit. The heart delights in heat, causing spiritual unrest. Macules are generated by the heart; the heart governs heat. Heat generates wind, which belongs to the liver. The two organs clash, causing convulsions. Treatment should purge the liver and tonify its mother (kidney), using *Daochi San* (Guiding Out Redness Powder) and *Dihuang Wan* (Rehmannia Pill).

**Zhu Danxi's General Principles for Treating Convulsion**

There are two types of pediatric convulsion: acute convulsion belongs to phlegm-heat and is suitable for cooling and purging. One method uses *Jianghuo Xiatan Wan* (Fire-Reducing Phlegm-Resolving Pill) taken with blood-nourishing decoctions. Chronic convulsion is governed by spleen deficiency, often fatal, and is suitable for warming and tonifying, specifically strengthening the spleen. It is highly erroneous to use a single medicine to treat both types. For acute convulsion with mouth sores, hidden heat in palms, phlegm cough, and wheezing, emetic therapy is used. For severe cases, *Gua Di San* (Melon Sepal Powder); for mild cases, *Chi Xiaodou* (Vigna Angularis Seed) and *Kushen* (Sophorae Flavescentis Radix) powder, taken with sour juice. After slight stabilization, take *Tongsheng San* (Universal Salvation Powder) as honey pills. Occasionally, take dried mulberry bugs (*Sang Niu*) ground into powder to pacify wind. Another formula uses *Bohe Ye* (Menthae Haplocalycis Herba) and *Hanshui Shi* (Calcitum) each 1 liang, *Qingdai* (Indigo Naturalis), *Bai Jiangcan* (Bombyx Batryticatus), and *Chensha* (Cinnabar) each 1 qian, *Quanxie* (Scorpio) 2 pieces, *Zhuya Zaojiao* (Gleditsiae Sinensis Fructus Spine) and *Huaijiao* (Gleditsiae Sinensis Fructus) each 5 fen, ground into powder, mixed with *Dengxin Cao Tang* (Junci Medullae Decoction) and milk for administration. For opisthotonos and fixed gaze due to fright, use *Nanxing* (Arisaematis Cum Bile) and *Banxia* (Pinelliae Rhizoma) with ginger juice and bamboo sap for administration, plus moxibustion on *Yintang* (EX-HN3). For frequent vomiting and diarrhea, indicating impending chronic convulsion, use Qian's *Baizhu San* (Atractylodis Macrocephalae Powder) added with *Shanyao* (Dioscoreae Rhizoma), *Biandou* (Lablab Semen Album), and fried *Roudoukou* (Myristicae Semen) baked in flour, each 1 qian, decocted with ginger slice. If chronic convulsion has already manifested, add *Xixin* (Asari Radix et Rhizoma) and *Tianma* (Gastrodiae Rhizoma) each 1 qian, *Quanxie* (Scorpio) 3 pieces (tip removed), and *Baifuzi* (Aconiti Kusnezoffii Radix Praeparata) 8 fen baked in flour. For fright with diarrhea, use *Renshen* (Ginseng Radix), *Fuling* (Poria), *Shaoyao* (Paeoniae Radix), and wine-fried *Baizhu* (Atractylodis Macrocephalae Rhizoma), decocted with ginger. In summer, add *Jiang Huanglian* (Coptidis Rhizoma processed with ginger) and *Sheng Gancao* (Glycyrrhizae Radix et Rhizoma).

**Syndromes Associated with Specific Organs in Convulsion**

Abnormal upward deviation of the eyes indicates liver wind fright. Unprovoked laughter during the day indicates fright in the heart. Finger twitching in dreams indicates fright in the sinews. Fearfulness indicates fright in the spleen. Limb twitching in dreams indicates fright in the liver and heart. Red face turning black abnormally indicates fright in the kidney. Unprovoked biting indicates fright in the bones. Abnormal limb spasms indicate fright in the Triple Burner. Tongue protrusion in dreams indicates fright in the heart. Noisy breathing during sleep indicates fright in the lung and stomach. Blue-white complexion with unprovoked fever and shivering indicates fright in the spleen. Black facial hue with unprovoked screaming indicates fright in the kidney. The general principles for treating fright have specific formulas and ordered medication. Acute cases require immediate clearing of heat, dispersing wind, draining phlegm, stopping spasms, and opening orifices. Do not use harsh cold purgatives like *Badou* (Crotonis Fructus), *Xiaofen* (Mirabilitum), *Naobing* (Borneolum Syntheticum), *Shexiang* (Moschus), or *Niuhuang* (Bovis Calculus) immediately, as they may damage true qi and yuan yang. *Dahuang* (Rhei Radix et Rhizoma) is permissible. Children's constitutions are easily deficient or excess; warm and cool agents must be balanced. Inquire if previous physicians attempted to resolve the condition and determine if the presentation is true/false or favorable/unfavorable. Cold damage, wind strike, measles, smallpox, food stagnation, and developmental fever can also cause spasms (false spasms), each with distinct signs. If the jaw is not tight and there is no phlegm tide, assuming heat generates wind and administering toxic cold agents like borneol, musk, croton, calomel, bezoar, and calomine to forcefully drain phlegm and arrest wind damages the spleen and stomach, leading to chronic conditions and early death. Never damage the stomach qi in any disease. Physicians must be cautious. If symptoms persist after purgation, do not purge again. Resolve fright with methods for fright, heat with methods for heat, phlegm with methods for phlegm, and excess with methods for removing excess. When heat clears, phlegm does not generate; when fright disperses, wind does not generate. When excess is removed, qi becomes peaceful, and the disease cannot arise. Qian Yi asked about *Wen Jing Wan* (Warming Fright Pill), *Liang Jing Wan* (Cooling Fright Pill), and *Li Jing Wan* (Promoting Resolution Fright Pill): why? Deficiency is warmed, excess is drained, heat is cooled.

**Opening Orifices for Convulsion**

Yang Shi stated: Convulsive spasms and blocked orifices are caused by phlegm blocking the *Zhongwan* (CV12) and stagnating in the joints. Phlegm congestion is driven by excess qi. To treat wind-phlegm, use *Banxia* (Pinelliae Rhizoma), *Nanxing* (Arisaematis Cum Bile), *Quanxie* (Scorpio), and *Jiangcan* (Bombyx Batryticatus). Also use *Suhe Xiang Wan* (Styrax Pill) and *Qingzhou Bai Wanzi* (Qingzhou White Pills), mixed with mint decoction and ginger juice for administration. This aims to direct qi downward so phlegm descends; once phlegm descends, orifices open naturally. If sneezing is not induced by nasal insufflation, the case is incurable.

**Incurable Syndromes of Convulsion**

Acute convulsion with eye rolling, oral bleeding, leg jumping, abdominal spasms, lethargy with picking at clothes, severe coma with shortness of breath, inability to receive medication, failure to induce sneezing via orifice-opening methods, and sudden crying with irritability are incurable. Chronic convulsion with cold limbs, vomiting/diarrhea/cough, dark complexion with despair, crow-like voice with stomach pain, hypochondriac movement, oral ulcers, stiff hair with head shaking, cyanotic immobile eyes, noisy saliva with wheezing, soft head, incontinence, and unilateral limb traction are all incurable. Chronic spleen wind with cold sticky sweat, rigid corpse-like posture, wheezing with soft head, curved back with lockjaw and head shaking, sawing-sound phlegm, lack of luster in face, pursed lips with coarse breathing are incurable.
