Cassia flower leaves, select tender ones, about five or six pieces. For boys, use an even number; for girls, use an odd number. Crush the leaves, fry three egg skins (or use eggs to make a thin skin/omelet), and apply to the infant's umbilicus. Replace when it cools down; after three or four applications, it will heal.

Another prescription: *Bombyx Batryticatus* (Jiangcan) nine strands, *Scorpio* (Quanzhe) nine specimens, *Borneolum Syntheticum* (Meibingpian) 3 fen, *Moschus* (Shexiang) half a fen, *Sanxiandan* 3 fen. Grind them all into fine powder. Mix with honey and sugar to form a cake, and apply to the umbilicus. Cover with any ordinary plaster. Dosage: one-third of the total amount for each year of age (e.g., 1/3 for one year old, 2/3 for two years old); for three years old, use the full prescription. Once the infant cries, immediately feed with breast milk or thin porridge. Careful nursing is essential.

Yet another prescription: Take two segments of earthworms with white necks (*Qiusong*). If they jump rapidly, use for acute convulsion (Ji Jing); if they move slowly, use for chronic convulsion (Man Jing). Add 1 fen of *Moschus* (Shexiang), crush thoroughly, and apply against the umbilicus. Cover tightly with a plaster externally.

Chronic convulsion (Man Jing) symptoms are most commonly acquired through vomiting and diarrhea in infants. It may result from prolonged malaria or dysentery, or following smallpox/rash eruptions, or from excessive use of purgatives due to wind-cold and food stagnation damaging the Spleen, or from innate constitutional deficiency, or from mistaken administration of cold-cooling herbs, or from overly aggressive descending/purging treatments for acute convulsion, or from neglect in nursing. All these can lead to this syndrome. Symptoms include coma and panting, persistent high fever, eyes open with惊厥/twitching, alternating chills and fever, dullness of the Three Yang channels, pale white/bluish-yellow complexion, greenish-white urine/stool, cracked mouth with bleeding but cold breath, diarrhea with cold sweat, undigested food in stool, cold limbs accompanied by abdominal pain and borborygmus, phlegm rattle in the throat, opisthotonos, dim vision. This is a deficiency syndrome. If cold-cooling herbs are used again, or digestive aids are employed, or *Fallopiam Radix* (Danshen - note: Danshen usually refers to Salvia, but here likely implies a specific phlegm-resolving context or typo for Danxing/Bile Star, WHO term for *Arisaematis Cum Bile*) and *Baolong Wan* are used to resolve phlegm, or *Gastrodiae Rhizoma* (Tianma) and *Scorpio* (Quanzhe) to dispel wind, or *Anemarrhenae Rhizoma* (Zhimu), *Phellodendri Cortex* (Huangbai), *Scutellariae Radix* (Huangqin), and *Coptidis Rhizoma* (Huanglian) to clear fire, or *Crotonis Fructus* (Badou) and *Rhei Radix et Rhizoma* (Dahuang) to remove accumulation, death occurs as easily as turning a palm. It is truly terrifying. One seeks to treat wind but finds no wind to treat; one seeks to treat惊 but finds no惊 to treat. This is truly due to Spleen and Kidney deficiency-cold, lone Yang floating outward, lacking Qi and root, extreme Yin-cold, causing the movement of wind. Treatment should first employ pungent-hot herbs, followed by warming and tonifying. Tonifying Earth (Spleen) controls Wood (Liver); treating the root treats the branch. Whenever an infant suffers from simultaneous vomiting and diarrhea, it is the most critical condition. If it recurs frequently, regardless of post-smallpox/rash status or cause, one must first use *Codonopsis Radix* (Renshen/Dangshen) and *Atractylodis Macrocephalae Rhizoma* (Baizhu) to rescue Stomach Qi, and *Zingiberis Rhizoma Praeparatum* (Jiang), *Cinnamomi Cortex* (Guizhi), and *Rehmanniae Radix Praeparata* (Shudihuang) to rescue Kidney Qi. Not only after food injury should emergency rescue be performed, but also after Wind-Cold or Summerheat injury. Although there were initially excess pathogens of Cold or Heat, vomiting and diarrhea have already expelled them completely. The Spleen and Stomach are empty, the granaries are depleted. Without emergency rescue, deficient phlegm may surge upward, and life may end in an instant. Quack physicians see these signs and mistakenly identify them as Heat or Food Stagnation, administering cooling herbs to clear fire and remove accumulation, leading to immediate deterioration. What can be done? If the error lies in using cold herbs, survival is difficult; it is better to err on the side of warming and tonifying, which can still be salvaged. This statement elucidates the principles of vomiting/diarrhea-induced convulsions thoroughly. Future practitioners should not ignore this. Below, the differentiation of chronic convulsion symptoms is listed.

Chronic convulsion with vomiting and diarrhea indicates Spleen-Stomach deficiency-cold.
Cold body: Yang Qi is suppressed and cannot reach the exterior. Often caused after taking cold herbs.
Flaring nostrils: True Yin is unsecured, deficient fire dries the Lungs.
Bluish-yellow and white complexion: Deficiency of both Qi and Blood.
Cold breath from mouth and nose: Obstruction in the Middle Jiao.
Greenish-white urine and stool: Complete lack of Fire in the Kidneys and Taiyang Bladder channel.
Sleepiness with protruding eyes: Insufficiency of Shen (Spirit) and Qi.
Twitching of hands and feet: Blood fails to circulate to the four limbs.
Opisthotonos: Blood deficiency causing tendon tension.
Alternating heat and cold: Scarcity of Yin-Blood, chaotic interaction of Yin and Yang.
Profuse sweating: Yang deficiency and insecure exterior.
Sunken fontanelle: Extreme deficiency.
Although the body has fever, lips are cracked and bleeding, yet the child does not desire cold tea/water (administering cold herbs increases danger). The vomited milk and excreted matter are poorly digested, indicating lack of Fire in Spleen/Stomach. Blackened/cracked lips indicate insufficiency of True Yin.

For the above chronic convulsion symptoms, observe if several match simultaneously. Then confidently treat according to the following two prescriptions without doubt.

**Zhuhan Dangjing Tang (Eliminate Cold and Dispel Convulsion Decoction)**
Properties are warm. Specifically treats infants with innate deficiency, or prolonged illness unresolved, or post-smallpox/rash medication errors leading to diarrhea/vomiting, transforming into chronic convulsion. Using clearing-heat or dispersing-wind methods worsens the condition. Administer this quickly. It opens cold-phlegm, expands the chest/diaphragm, stops vomiting, and eliminates convulsive pathogens, described as "returning Yuan Qi to the realm of non-existence." After one or two doses, vomiting gradually stops, which is the sign of efficacy. Recognize that if it is purely deficiency-cold, administer it without hesitation.
*Huajiao* (Zanthoxyli Pericarpium), *Paojiang* (Prepared Zingiberis Rhizoma) (each 1 qian); *Rougui* (Cinnamomi Cortex) (preferably with oil, remove bark, 1 qian); *Dingxiang* (Eugeniae Flos) (10 buds).
Grind into fine powder. Boil 3 liang of *Caosuxin Tu* (Furnace Heart Soil) in water, clarify, then decoct the medicine until half a cup remains. Administer frequently by force-feeding. Follow with the next prescription for miraculous effects.

**Jiawei Lizhong Dihuang Tang (Modified Regulate the Middle and Rehmannia Decoction)**
Assists Qi, nourishes Blood, expels disease, restores Yang. Specifically treats infants whose spirit is depleted, Qi and Blood severely damaged, appearing wretched and extremely emaciated, all of which can be reversed. Decoct strongly according to method and administer frequently. Its heaven-saving and root-restoring merits are indescribable.
*Shudihuang* (Prepared Rehmanniae Radix) (5 qian); *Danggui* (Angelicae Sinensis Radix), *Gouqi* (Lycii Fructus), *Dangshen* (Codonopsis Radix), *Suanzaoren* (Ziziphi Spinosae Semen, prepared), *Guzhi* (Psoraleae Fructus) (each 2 qian); *Baizhu* (Atractylodis Macrocephalae Rhizoma) (3 qian); *Yurou* (Corni Fructus), *Paojiang* (Prepared Zingiberis Rhizoma), *Rougui* (Cinnamomi Cortex), *Zhigancao* (Prepared Glycyrrhizae Radix et Rhizoma) (each 1 qian).
Add 3 slices of fresh ginger, 3 dates flesh, and 2 crushed walnuts as guides. Still use 2 liang of *Caosuxin Tu* (Furnace Heart Soil) boiled in water, clarified, then decoct the medicine. Obtain one teacup of concentrated juice. Add 5 fen of *Fuzi* (Aconiti Lateralis Radix Praeparata), boil with water, mix in, and administer according to the child's size in divided doses. If cough persists, add *Suke* (Papaveris Pericarpium) and *Jinyingzi* (Chrysanthemi Fructus - note: Jin Ying Zi is Rosae Laevigatae Fructus) (each 1 qian). If high fever persists, add *Baishao* (Paeoniae Radix Alba) 1 qian. If diarrhea persists, add *Dingxiang* (Eugeniae Flos) 6 fen. After one dose, remove *Fuzi*, using only 7 *Dingxiang*. Every two to three days, use 2-3 fen of *Fuzi* again. Because *Fuzi* is extremely hot, remove it once the disease is addressed. Overuse of *Fuzi* often causes urinary retention. Without *Fuzi*, internal stagnation and knotting persist. Without *Dingxiang*, diarrhea continues. If the infant's deficiency-cold is extreme, *Fuzi* may be used up to 3 qian. This formula nourishes Yin and secures the root, called a divine agent for treating infant chronic convulsion. If vomiting/diarrhea is not severe, or slight convulsions appear, and the Stomach can tolerate medicine, with normal feeding and bowel movements, there is no need to take Zhuhan Dangjing Tang. Taking just one dose of this medicine will settle wind and clarify the mind. If the infant has not yet developed convulsions, merely sleepiness, persistent fever, intermittent fever, quiet during day but fever at night, or afternoon fever, these all belong to Yin deficiency and are suitable for this formula. For newly ill, robust infants with red eyes and thirst, it is an excess-fire syndrome, and temporary clearing/resolving methods may be used. However, true excess-fire must present with constipation, strong voice, and preference for cold drinks. If vomiting and diarrhea occur together, it is clearly not excess-fire.
