*Zhi Fa Xin Yao* (Essentials of Treatment Methods) records: It is often heard from an old physician that pediatric convulsions due to fright (Jing Chu, spasms and convulsions caused by fright or excessive heat) are mostly heat syndromes. If Jingfeng medicines such as Bai Fu Zi (Aconiti Kusnezoffii Radix), Quan Xie (Scorpio), Jiang Can (Bombyx Batryticatus), and Chuan Wu (Aconiti Radix) are used initially, it will lead to deteriorated conditions (Huai Zheng). Later, a physician specializing in pediatrics treated the condition solely with Dao Chi San (Coptis Decoction) added with Di Huang (Rehmanniae Radix) and Fang Feng (Saposhnikoviae Radix). After three doses to guide out and clear the pathogenic heat from the Heart channel, the convulsions ceased; subsequently, Ning Shen Gao (Spirit-Calming Paste) was administered, yielding miraculous effects.

The Preface to *Zhi You Xin Shu* (Heart Book of Treating Children) records: Wu Ling San (Five-Ingredient Powder with Poria) is used by various schools only to resolve Cold-Warm-Dampness, Summerheat-Toxicity, and Cholera. However, De Xian applied it to diseases such as Jingfeng, Tan Chu (Phlegm-Convulsion), and Chuang Zhen (Skin Rashes), using it throughout all four seasons. Hu Shengzhai, former Vice Prefect of Hengzhou Prefecture, asked why Wu Ling San could cure his son's Jingfeng illness. De Xian replied: "This formula uses Fu Ling (Poria) to calm the Spirit of the Heart; Ze Xie (Alisma) guides urination, so that when the Small Intestine is unblocked, the Qi of the Heart flows freely; Cinnamon Twig (Gui Zhi) suppresses the Qi of the Liver, causing wind to cease naturally, thus treating Jingfeng. There are also rationales for applying it to other syndromes." Shengzhai deeply agreed. This illustrates his adept use of Wu Ling San.

Pediatric Jingfeng convulsions are often viewed by physicians as a single disease, leading them to indiscriminately prescribe mineral substances (Jin Shi), Bing Pian (Borneol), She Xiang (Musk), Wu Gong (Centipede), Jiang Can (Bombyx Batryticatus), snakes, and scorpions. This not only brings no benefit but exacerbates other symptoms. De Xian argued that some Jingfeng cases involve convulsions due to fright, while others involve convulsions due to Wind stagnation. Fright belongs to the Heart, Wind belongs to the Liver, and Qi stagnation can also cause convulsions, as described by Chen Shi as 'accumulated Qi causing convulsions,' though he did not provide specific formulas. I treat Jingfeng according to the specific symptoms. For convulsions due to Qi stagnation, I use methods to broaden and regulate Qi, primarily using Zhi Ke (Aurantii Fructus) and Zhi Shi (Aurantii Fructus Immaturus). Once, when a patient sought urgent medicine for sudden convulsions, I instructed them to take Pu Jia San (Shop Dispersion), and the convulsions stopped; the family was deeply grateful. This represents another unique insight into treating convulsions.

'Jing' refers to Spasm (Jing). Spasms are divided into deficiency and excess, and rigid and flaccid types. Acute cases should be treated with sweating to clear heat and eliminating phlegm, commonly known as Acute Jingfeng; chronic cases should be treated by supporting the Spleen and benefiting Qi, commonly known as Chronic Jingfeng. One must strictly avoid blind acupuncture and the erroneous administration of toxic and potent mineral substances. Qian Shuzi's Huichun Dan (Revival Pill) from Guangdong is famous domestically and internationally, yet it can only treat acute conditions. If misused for chronic conditions, danger will appear immediately. Its package insert boasts exclusive treatment for both acute and chronic Jingfeng, attempting to rule all diseases with one medicine to attract customers. Does he not know this is unintentional homicide, inviting heavenly retribution? I advise the pharmacy to correct its insert promptly to benefit countless people and develop its business, which is my earnest hope.

Note: When children inhale external pathogens, the Lung channel is injured first, presenting initially with cold/fever and coarse breathing. If prolonged, the pathogen gradually enters the Pericardium channel. Although there may be slight sweating, symptoms include abundant phlegm, nasal flaring, irritability, and clouded consciousness. One must strictly avoid blindly administering pungent-aromatic and heavy mineral sedatives, which consume Yin fluids, intensify heat, weaken healthy Qi, and trigger sudden Liver Wind movement. This leads to limb convulsions and upward staring of the eyes, resulting in spasm and syncope. Do not mistake this for ordinary Jingfeng, causing further failures. If treated before the disease becomes rampant, using acrid-cool herbs to open the Lungs, followed by sweet-cold herbs to clear heat, moisten dryness, and descend phlegm, recovery can occur within ten days. I have verified this on many patients, correcting numerous medical errors. Specifically, this is Warm Pathogen invading internally, consuming Yin fluids, and causing wild Liver Wind movement; it is actually not caused by fright. I often see families in panic and physicians ignorant, blindly prescribing Jingfeng medicines, turning mild cases severe and severe cases fatal. Recalling how Yu Jiayan criticized the name 'Spasm Disease,' it was like a loud cry for help. Yet today, we still cannot turn back the tide. To remain silent while lives are disregarded is unbearable.
