急惊是有余之症,属肝木、心火阳邪太旺,宜直泻之,降火下痰是也。五脏俱有阴阳,如肝气为阳为
火,肝血为阴为水。肝气旺则肝之血衰矣,火妄动则水被煎沸不宁矣。阳旺阴消,风火相搏,阴血走散,
势所必至也,故亦宜养血。急惊虽属肝、心,然木火旺则肺金受亏,不能平木,木来克土,斯损矣,故亦
宜养脾。况治惊诸药,大率祛风、化痰、泻火峻厉及脑、麝辛散之味,易于消阴血、损脾胃者。故治有余急
惊之症,先须降火下痰一、二服,后加养血安神之药。若饮食少,大便溏,或吐泻,则当兼补脾胃。若脾胃
原虚,当于直泻药中加补脾药。若屡作屡服利惊驱逐
之药,便宜认作脾虚血散,治惊药内加养血补脾药,不可用温热丁香等药,恐助胃火,宜参、术、芍药等以
补脾中气血,麦门冬、黄连以清金制木。
愚按前症若肝经风热,抽搐,目 ,筋急,痰盛等症,用四物汤以生肝血,钩藤钩以清肝火,更用四
君子以补脾土。若肝经血燥,发热,惊搐,眼 ,痰盛,筋挛,用六味丸以滋肾水、生肝血,用四君子加
芍药以补脾土,生肺金。若肺金克肝木,用六君子以实脾土,芍药、木香以平肺金。若屡服利惊之药而脾
胃虚寒者,须用六君子以补脾胃,加丁香、木香以培阳气。若脾土虚寒,肾水反来侮土,而致中寒腹痛、
吐泻、少食等症者,用益黄散以补脾土而泻寒水,庶几不致慢惊矣。治当审察虚实。凡症属有余者,病气

Ji Jing (Acute Convulsion) is a syndrome of excess, caused by the excessive flourishing of Yang pathogens in Liver Wood and Heart Fire. Treatment should directly purge the pathogen, employing methods to descend fire and eliminate phlegm. The five Zang organs all contain Yin and Yang; for instance, Liver Qi is Yang and corresponds to Fire, while Liver Blood is Yin and corresponds to Water. When Liver Qi flourishes excessively, Liver Blood becomes deficient; when Fire moves recklessly, it boils the Water (Yin fluids), causing internal unrest. The flourishing of Yang and the decline of Yin lead to the struggle between Wind and Fire, resulting in the dispersion of Yin Blood, which is an inevitable trend; therefore, nourishing blood is also indicated. Although Ji Jing primarily involves the Liver and Heart, excessive Wood and Fire damage Lung Metal, preventing it from moderating Wood (Ping Mu). Consequently, Wood overacts on Earth (Spleen/Stomach), damaging it; thus, tonifying the Spleen is also indicated. Moreover, most herbs used to treat Jing disorders are harsh in nature, possessing strong wind-dispelling, phlegm-resolving, and fire-purging properties, or contain pungent and dispersing substances like Borneol and Musk, which easily consume Yin Blood and damage the Spleen and Stomach. Therefore, when treating Ji Jing of excess, one must first administer descending-fire and phlegm-resolving formulas for one or two doses, followed by adding blood-nourishing and spirit-calming herbs. If dietary intake is reduced, stools are loose, or vomiting and diarrhea occur, the Spleen and Stomach should be supplemented simultaneously. If the Spleen and Stomach were originally deficient, tonifying Spleen herbs should be added to the direct purgative formulas. If the condition recurs frequently and purgative Jing-removing drugs have been taken repeatedly, it should be recognized as Spleen deficiency with blood dispersion; blood-nourishing and Spleen-tonifying herbs should be added to the Jing-treatment formula. Warm and acrid herbs such as Ding Xiang (Caryophylli Flos) should not be used, as they may aggravate Stomach Fire. Instead, Ren Shen (Ginseng Radix et Rhizoma), Bai Zhu (Atractylodis Macrocephalae Rhizoma), and Shao Yao (Paeoniae Radix Alba/Rubra) should be used to tonify Qi and Blood in the Spleen, while Mai Men Dong (Ophiopogonis Tuber) and Huang Lian (Coptidis Rhizoma) should be used to clear Lung Metal to control Liver Wood.
In my opinion: For the aforementioned symptoms, if they are due to Wind-Heat in the Liver Channel, manifesting as convulsions, abnormal eye movements (such as deviation or upward staring), tendon stiffness, and abundant phlegm, Si Wu Tang (Four Substances Decoction) should be used to generate Liver Blood, Gou Teng Gou (Uncariae Ramulus cum Uncis) to clear Liver Fire, and Si Jun Zi Tang (Four Gentlemen Decoction) to tonify Spleen Earth. If they are due to Blood Dryness in the Liver Channel, manifesting as fever, frightful convulsions, abnormal eyes, abundant phlegm, and tendon spasms, Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) should be used to nourish Kidney Water and generate Liver Blood, and Si Jun Zi Tang plus Shao Yao to tonify Spleen Earth and generate Lung Metal. If Lung Metal overacts on Liver Wood, Liu Jun Zi Tang (Six Gentlemen Decoction) should be used to solidify Spleen Earth, and Shao Yao plus Mu Xiang (Aucklandiae Radix) to moderate Lung Metal. If repeated use of Jing-purgative drugs leads to Cold-Deficiency of the Spleen and Stomach, Liu Jun Zi Tang should be used to tonify the Spleen and Stomach, with the addition of Ding Xiang and Mu Xiang to cultivate Yang Qi. If Spleen Earth is cold-deficient, Kidney Water may counter-rebel against Earth, leading to Middle-Jiao Cold, abdominal pain, vomiting, diarrhea, and poor appetite; Yi Huang San (Yellow Protection Powder) should be used to tonify Spleen Earth and drain Cold-Water, thereby hopefully preventing the progression to Man Jing (Chronic Convulsion). Treatment requires careful examination of Excess and Deficiency. Symptoms belonging to Excess represent Pathogenic Qi; those belonging to Deficiency represent Primal Qi (Yuan Qi). Therefore, even when dealing with Excess, one must consider the potential for Deficiency and take preventive measures, thereby minimizing errors.
