一小儿，病后遇惊，即痰盛切牙，抽搐摇头，作泻，却服脑、麝、朱砂等剂，以致慢惊而卒。
急惊风反复发作且经过多次治疗，若使用了过多的直泻（攻下/清热）药物，会导致脾气受损、阴液消耗，从而转变为慢惊风。此时应当以补脾养血为主，辅以安心神、清肺热、平抑肝风的药物。
我按语：上述病症多因呕吐腹泻，导致脾胃虚损，肝木之气乘虚克制脾土，或者肾水反来侮犯脾土所致。因此症状表现为似有抽搐而实际抽搐轻微。治疗时先用钩藤饮子；如果发作时抽搐稍微减轻，再使用宝鉴天麻散。如果出现呕吐腹泻、不能进食的情况，急需使用木香异功散来充实脾土，疾病自然痊愈；如果未见效果，使用六君子汤加入木香、炮姜来温补脾土；如果仍然无效，紧急加入附子以回阳救逆。大概慢惊风的症候，外表看似有虚热，内部却是真寒证。没有风邪可以驱逐，没有痰浊可以驱除，只应以温补脾胃为主要治法。大凡因风引起的抽搐，会出现眼睛发青、面色发红；因惊引起的抽搐，会有呼叫、抽搐痉挛的表现；因食积引起的，会有嗳气、呕吐、气息闷堵的症状；肺脾虚弱则产生粘稠痰液，喉间发出像拉锯一样的声音。这是因为心火不能生助脾土，脾土不能生助肺金，导致肺不能主司气机，脾不能统摄涎液，所以涎液泛溢上行，而在喉中发出声音！如果使用祛风、治痰、理气的药剂，会导致正气耗散、阴液消亡，从而加速病情危重。
太平府王职坊的一位官员之子，患有疟疾，严格地使用化痰的药剂，导致虚证全部出现，非常类似惊风。他对我说：“这是怎么回事？”我说：“小便频数，是肝经阴虚；两眼频繁眨动，是肝经风热；作呕、食欲不振，是胃气虚弱；泄泻且有里急后重感，是脾气虚弱。”使用补中益气汤和六味地黄丸后痊愈。
举人余时正的公子，因伤食引发丹毒，服用发表（解表）的药剂后，出现手足抽搐；又服用抱龙丸，出现眼睛上翻、气喘、痰多等症状。我说这是脾胃亏损而转变为慢惊风，没有风邪可以祛除，没有痰浊可以驱逐，这是虚象。于是使用六君子汤加入附子，一剂后病情安定，两剂后痊愈。
Frequent recurrences of acute convulsion (Ji Jing Feng) treated with numerous purgative or clearing-draining medicines will damage the Spleen Qi and consume Yin fluids, transforming into chronic convulsion (Man Jing Feng). The treatment should primarily focus on tonifying the Spleen and nourishing Blood, assisted by herbs that calm the Mind, clear Lung Heat, and subdue Liver Wind.
My commentary: The aforementioned conditions are mostly caused by vomiting and diarrhea leading to Spleen-Stomach deficiency and damage, where Liver Wood overacts upon Spleen Earth, or Kidney Water counter-attacks Spleen Earth. Thus, the symptoms present as apparent spasms without actual severe convulsions. Initially use Gouteng Yinzi (Uncaria Decoction); if the spasms subside slightly after onset, then use Baojian Tianma San (Baojian Gastrodia Powder). If accompanied by vomiting, diarrhea, and anorexia, urgently use Muxiang Yigong San (Aucklandia Six Gentlemen Powder) to fortify Spleen Earth, and the disease will resolve itself; if there is no response, use Liujunzi Tang (Six Gentlemen Decoction) added with Muxiang (Aucklandiae Radix) and Paojiang (Prepared Zingiberis Rhizoma) to warm and tonify Spleen Earth; if still ineffective, urgently add Fuzi (Aconiti Lateralis Radix Preparata) to restore Yang. Generally, the syndrome of chronic convulsion presents with exterior false heat but interior true cold. There is no wind to dispel and no phlegm to drive away; the primary approach must be warming and tonifying the Spleen and Stomach. Generally speaking, convulsions due to Wind manifest with greenish eyes and red face; those due to Shock manifest with crying out and spasmodic jerking; those due to Food Stagnation manifest with belching, vomiting, and chest oppression. Deficiency of Lung and Spleen generates sticky phlegm, producing a sawing sound in the throat. This occurs because Heart Fire fails to generate Spleen Earth, and Spleen Earth fails to generate Lung Metal, resulting in the Lung’s inability to govern Qi and the Spleen’s inability to control saliva. Consequently, saliva overflows upward, causing sounds in the throat! If agents for dispelling Wind, resolving Phlegm, or regulating Qi are used, it will scatter Zheng Qi and consume Yin, accelerating the critical condition.
The son of an official from Wangzhi Fang in Taiping Prefecture suffered from malaria. He strictly used phlegm-resolving formulas, leading to the manifestation of all deficiency syndromes, closely resembling convulsion. He asked me, "What is happening?" I said, "Frequent urination indicates Yin deficiency of the Liver Meridian; frequent blinking of both eyes indicates Wind-Heat in the Liver Meridian; nausea and poor appetite indicate weak Stomach Qi; diarrhea with tenesmus indicates weak Spleen Qi." He recovered after using Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) and Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia).
The son of Juren Yu Shizheng contracted carbuncle (Danshu) due to food stagnation. After taking exterior-releasing formulas, he developed spasms of the hands and feet; after taking Baolong Wan (Embrace Dragon Pill), he developed retracted eyes, asthma, and profuse phlegm. I stated this was a transformation into chronic convulsion due to Spleen-Stomach damage. There is no Wind to dispel and no Phlegm to expel; this is a deficiency pattern. I subsequently prescribed Liujunzi Tang (Six Gentlemen Decoction) added with Fuzi (Aconiti Lateralis Radix Preparata). After one dose, the condition stabilized; after two doses, he was cured.
A child, after recovering from illness, was startled by fright, immediately developing profuse phlegm, teeth grinding, spasms, head shaking, and diarrhea. However, he administered formulas containing Bull Brain (Nao), Musk (She Xiang), and Cinnabar (Zhusha), leading to death from chronic convulsion.
