The physician diagnosed it as Yang Epilepsy (Yang Xian), characterized by spasms and convulsions of the hands and feet, flooding of saliva, and high fever. The physician employed purgation therapy, often using medicines containing Calomel (Qingfen) or Mercury (Shuiyin), and Croton Seed (Badou).

After the patient regained consciousness, the spirit remained lethargic, with a reluctance to suckle or eat. If there is residual heat, to ensure a peaceful recovery and restoration of harmony, only mild and stable medicines should be used to regulate Stomach Qi (Wei Qi). One must not directly administer drying and heating medicines. If such medicines are taken, the condition will recur; what is surprising about this?

Zeng Shirong commented: After an attack of Wind-convulsion (Jing Feng), the Stomach Qi is mostly deficient. The infant does not desire food, appears listless and silent, or suffers from persistent diarrhea. At this time, one can only assist in generating Stomach Qi. It is necessary to incorporate wind-extinguishing herbs into Guanyin San (Guanyin Powder). This refers to using Scorpion (Quanxie), Gastrodia Rhizome (Tianma), Bombyx Batryticatus (Jiangcan), Aconitum Carmandii Rhizome Preparatum (Baifu), Saposhnikovia Root (Fangfeng), and Notopterygium Root (Qianghuo), decocted together with Fresh Ginger (Shengjiang) and Jujube (Zao). Naturally, the Stomach Qi will strengthen, diarrhea will cease, and various wind syndromes will not arise. Although the symptoms of wind-convulsion have subsided, if the spirit has not fully recovered, one cannot assume that everything is fine. If tonifying medicines such as Dried Ginger (Ganjiang), Cardamom (Doukou), Sulfur (Huang), and Prepared Aconite Root (Fuzi) are used, the heat will return, and the condition will relapse. This is not curing the disease but rather medical error due to the physician's recklessness and the family's lack of insight. This is something that must be communicated. When treating the syndrome of Acute Wind-convulsion (Ji Jing), the focus lies on medical intervention. How can one rely merely on "conditioning" theories? Medication administration often requires sustained effort. If treatment is delayed or lenient, the symptoms will deepen and worsen. Since the physician knows that purgation is indicated, they should assess the severity. For instance, if the illness is five or six parts severe, purging three or four parts may suffice. Once the bowels are unblocked, heat is eliminated, and phlegm dissipates, the disease and symptoms will gradually diminish step by step until recovery. If one fails to estimate the condition and indiscriminately uses harsh purgatives, it causes excessive damage, injuring the Zang-Fu organs. The disease may transmit to Yin syndromes, manifesting as Chronic Wind-convulsion (Man Jing Feng). At that point, attempting to temporarily generate Stomach Qi and restore Yang is indeed futile and late. Any competent physician should know this.

The physician diagnosed it as Yin Epilepsy (Yin Xian). This largely results from the excessive use of cold and cooling medicines for Acute Wind-convulsion, causing the condition to deepen and transform into Chronic Wind-convulsion. Or it arises because vomiting and diarrhea persist, leading to Chronic Wind-convulsion. Or it occurs because bathing led to wind-cold invasion that was not resolved, triggering Chronic Wind-convulsion. Or it transforms from untreated Wind-Epilepsy or Food-Epilepsy into Chronic Wind-convulsion. Or it becomes Chronic Wind-convulsion due to deficiency caused by coughing and expectoration. There are many causes, summarized here. Families fear convulsions but not diarrhea; good physicians fear persistent diarrhea but not convulsions. If diarrhea persists, the wind-convulsion intensifies. If one treats the convulsion while using cold and cooling medicines, diarrhea will increase, and the condition will worsen.

Zeng Shirong commented: Children have weak and timid Spleen and Stomach. When vomiting and diarrhea first occur, there are five types of symptoms: Heat Vomiting, Cold Vomiting, Deficiency Vomiting, Phlegm Vomiting, and Food Vomiting. Heat Vomiting refers to when the mother drinks alcohol, eats fatty, roasted, fried, or preserved foods, or contracts wind or summerheat, causing heat to enter the infant's mouth and stomach upon nursing, resulting in Heat Vomiting. Cold Vomiting refers to when the infant's Stomach is cold, and vomiting occurs after consuming cold raw foods. Deficiency Vomiting refers to when the infant is emaciated and spiritually exhausted, with unresolved malnutrition (Gan accumulation) and long-term Stomach deficiency, leading to vomiting. Phlegm Vomiting refers to when the infant's Stomach Qi is originally deficient, contracts cold pathogenic factors, generates phlegm and heat, which stagnate in the chest and diaphragm, causing vomiting. Food Vomiting refers to when the infant has a weak Stomach, lacks dietary discipline, forces food intake damaging the Spleen, generates heat, feels lethargic, and vomits followed by reflux. Families only know of vomiting but do not understand its cause. Furthermore, when vomiting and diarrhea occur together, it is named Cholera-like disorder (Huo Luan). Regarding the severity of vomiting, there are five degrees: initially, milk flows out naturally, called Spillage (Yi); if spilling continues, it is called Vomiting (Tu); if vomiting persists, it becomes Retching (Ou); if retching continues, it transmits to Reflux/Reversal (Ni); if reversal continues, it becomes Hiccups (Yue). From retching, reversal, to hiccups, there is sound and qi movement. Retching involves opening the mouth to make sound; Reversal involves upward counterflow and stagnation of qi in the chest and heart; Hiccups involve no substance to expel, caused by deficiency of the diaphragm and cold of the Stomach drawing qi, producing sound. This syndrome is ominous; within moments, the syndrome changes, transforming into Chronic Spleen Wind (Man Pi Feng). For Heat Vomiting, first eliminate wind-phlegm; for Cold and Deficiency Vomiting, generate Stomach Qi; for Phlegm Vomiting, drain the phlegm, then administer Zhengqi San (Zhengqi Powder); for Food Vomiting, administer Taqi Wan (Taqi Pill). How can they all be treated uniformly? Persistent vomiting and diarrhea lead to Spleen deficiency and generation of wind. Eyes open indicates Chronic Wind-convulsion; eyes closed indicates Chronic Spleen Wind. Inappropriate treatment, especially using convulsion medicines for purgation, leads to death instantly; how can it be saved? Infants vary in age; conditions vary in deficiency or excess. Some develop wind after three to five days of vomiting and diarrhea; some develop it within half a day. Generally, for girls, vomiting is urgent; for boys, diarrhea is rapid. If Qi deficiency leads to sudden profuse diarrhea or vomiting, it occurs immediately. Only Malnutrition Diarrhea (Gan Xie) does not form wind syndromes. Water-like diarrhea leads to Wugu Syndrome (infantile paralysis/wasting), ultimately resulting in death from deficiency and exhaustion. However, stopping diarrhea by resolving intestinal stagnation is good; generating Stomach Qi for vomiting is correct. Wind-extinguishing medicines can be added. Convulsion medicines and cold/cooling medicines must absolutely not be used, nor should strongly heating medicines be used. The syndrome belongs to Yin syndromes. Physicians must exercise judgment; avoiding superstition is fortunate.
