The neck is flaccid and lacks strength; the throat sounds like a saw being pulled. The face appears red as if painted, and the eyes are dim without luster. The mouth opens with coarse breathing; the feet are cold, straight, and elongated. The child gnaws clothes and bites randomly; blood stasis is passed in the intestines. The eyes open and then close again; the whole body is stiff like a corpse. These ten conditions represent post-convulsion diseases of severe prognosis; do not hesitate further in treatment.

In acute convulsion (Ji Jing), if the black pattern on the Wind Gate (Feng Guan) of the finger vein extends straight, it indicates a fatal condition. In chronic convulsion (Man Jing), if two purple patterns on the Qi Gate (Qi Guan) transmit to the Wind Gate, it indicates a fatal condition. If these signs are absent, although the condition is ominous, it is not necessarily fatal.

Chronic convulsion often occurs after prolonged illness when the meridians are already deficient, compounded by the excessive use of cooling agents, which weakens the Spleen and Stomach. This leads to weakness in the limbs, bodily fatigue, a pale face, reluctance to open the eyes, subtle or intermittent spasms, frequent lethargy, dull spirit, and white lips and mouth. The pulse may be floating or sunken; the body temperature may be warm or cool. There may be no initial fever yet sudden high heat, or no initial phlegm yet a sawing sound in the throat due to a cluster of deficiency-heat and phlegm. When Spleen and Stomach deficiency causes Earth to be depleted and Wood to insult it, convulsions also appear. Since these symptoms develop gradually and slowly, it is named Chronic Convulsion. After a major illness in a frail child, or due to external contraction of wind-cold, the Spleen and Stomach become even more deficient, allowing wind to enter. At this stage, one should not merely dispel wind or drive away convulsion; only warming and tonification are appropriate. There is no rationale for using sweating or purging methods. If phlegm-resolving purgatives are mistakenly used, phlegm descends with the Qi, and Qi perishes with the phlegm. For warming and tonification, suitable herbs include: Poria (Fuling), Tangerine Peel (Chenpi), Gastrodia Rhizome (Tianma), Saposhnikovia Root (Fangfeng), Chinese Yam (Shanyao), Lablab Bean (Bian Dou), Atractylodes Macrocephala Rhizome (Baizhu), Whole Scorpion (Quanxie), Bombyx Batryticatus (Jiangcan), Typhonii Rhizoma Praeparatum (Baifuzi), and Pinellia Ternata Rhizoma Praeparatum cum Zingibere et Alumine (Jiangzhi Banxia). If the deficiency is severe, add Ginseng Radix et Rhizoma (Renshen); if appetite is poor, add Lotus Seed (Lianrou); if cold is severe, add Aucklandiae Radix (Muxiang) and Caryophylli Flos (Dingxiang). Even if transmitted from acute convulsion, use Arisaema Cum Bile (Dansheng) to resolve phlegm and Baizhu to regulate the Stomach; do not use cooling medicines.

Slow Spleen Convulsion (Man Pi Jing) often results from prolonged diarrhea, and Stomach-deficiency convulsion from prolonged vomiting. Spleen and Lung have a mother-child relationship. When Spleen and Stomach are deficient, Lung Qi suffers first, producing stubborn phlegm. Phlegm flows within the Lung, making sounds like chicks chirping, accompanied by occasional lethargy, deviated open eyes, entering via convulsion. Suitable herbs include: Renshen, Baizhu, Shanyao, Myristica Seed (Roukou), Muxiang, Jiangcan, Quanxie, Tianma, Dingxiang, Baifuzi. If there is phlegm, add Banxia, Dansheng, and Fritillariae Bulbus (Beimu); for severe cases, Black Aconite Root (Hei Fuzi) can be used.

During summer days with intense heat causing vomiting and diarrhea, slow convulsion may also occur. Refer to the Vomiting and Diarrhea section for original prescriptions; if cold is severe, add Fuzi.

Infants within their first month showing elevated temperature, upward turning of the eyes, clenched fists, locked jaw, teeth grinding, stiffness of the body and waist, flooding saliva with vomiting, spasms with crying and fright, retracted cheeks, open fontanelle, or red cheeks with blue face, and upward gaze, must not be mistaken for Slow Spleen Wind and treated recklessly with warming medicines. One must observe if the area between the eyebrows shows bright red or greenish-red color; only then can specific treatments be considered. Suitable herbs include: Fangfeng, Coptis Rhizoma (Huanglian), Aurantii Fructus Immaturus (Zhishi), Dansheng, Quanxie, Tianma. In severe cases, Calculus Bovis (Niuhuang Wan) or Xiao Hong Wan can be used, mixed with pig milk into pellets.
