【钱乙】疮疹引起的抽搐，是由于风邪与火邪相互克制所致，只有出疹才会引发抽搐。疹由脾所生，当脾气虚弱时，肝气旺盛便会乘虚侵袭，木气克制土气，热气相互激荡，扰动心神。心主喜，受热则神气不安，因而发生抽搐并演变为痫证。子（此处指肾或子时相关脏腑，结合上下文语境及“子为心所生”之误，通常理解为五行相生关系中的下一环节或特定脏腑关联，但原文直译为：子是心所生的，心产生热，热则生风，风归属于肝，心和肝两脏相互搏结，风火相争，所以发生抽搐。）治疗应当泻心、肝二经之火，补益其母脏，以栝蒌汤为主方。（张元素云：各种疼痛、瘙痒的疮疡都归属于心，无论火邪虚实，都要从心火的角度论述。脾虚则肝气乘袭，肝与心火相合，所以使用栝蒌汤。如果脾土实证，火旺逆乘而成为痫证，这是实邪。大便干结的用泻青丸，大便稀软的用泻青汤，也应当通过脉象来辨别。）
【李杲】凡是痘疹尚未发出就出现抽搐的，是外感风寒邪气，内发心热所致，应当用茶粉送服解毒丸，或以犀角地黄汤主治。
【世医】治疗疮痘欲出之时，身体发热烦躁，忽然发生惊厥抽搐，宜用驱风膏、小如圣饮；若小便不通，用八正散；若痰涎壅盛，用利惊丸、抱龙丸，根据症状酌情施用。
【朱震亨】欲发疮疹之前，先出现身体发热、惊跳、抽搐，这不是惊风，宜用发散药治疗。
【世医】麻痘风搐方
人参 羌活 防风 僵蚕（醋炒） 南星（姜制） 白附子（姜制） 甘草（炙）
以上药材等分，加生姜三片，水煎服，抽搐立即停止。
【钱乙】疹病之后欲发痫证，其余疮毒难以引发痫证，是因为木气胜脾，木气归于心故也。若属凉惊，用凉惊丸；若属温惊，用粉红丸（即温惊丸）。
【《活幼心书》】治疗痘疮疼痛，用温惊丸，用水化开服用。（方剂见前惊搐条下）
【张元素】治疗疮出后烦痛，用五物木香散。
青木香（二两） 丁香 零陵香（各一两） 麝香（一分） 白矾（一两）
每次服用四钱，加水一小盏半，煎服。热势盛者，加犀角一两。若无犀角，可用升麻代替。轻症者，一服即大效。
又一方：用芒硝调和猪胆涂于疮上，使其松动，痂皮脱落且不留疤痕，随后用黄土涂抹效果良好。此病若小便涩滞有血者，病情危重难治。疮背黑陷不出脓者，死不治。
【世医】痘疹即将结痂时，干燥坚硬而疼痛，宜涂酥油滋润，痂皮可揭去则揭去。若无酥油，可用猪油煎汁代替。这种疼痛不是服药所能免除的。
[Qian Yi] Convulsions caused by pox and rashes result from the mutual overcoming of wind and fire; only rashes can induce convulsions. Rashes are generated by the Spleen. When the Spleen is deficient, the exuberant Liver Qi overacts upon it (Wood overacting on Earth). The heat qi strikes each other, disturbing the Heart Spirit (Shen). Since the Heart governs joy, heat causes the spirit to become unsettled, leading to convulsions that evolve into epilepsy (Xian syndrome). [Note: The original text "Zi is born of the Heart" contains a theoretical inconsistency in standard Five Elements theory as Kidney/Water is born by Metal/Lung, not Fire/Heart directly in the generating cycle, or refers to a specific lineage. Translated literally as per instruction.] Zi is born of the Heart; when the Heart generates heat, heat generates wind. Wind belongs to the Liver. The two organs (Heart and Liver) contend with each other, wind and fire struggle, thus convulsions occur. Treatment should involve draining the Heart and Liver and tonifying their mothers (the sources), using Gualou Tang (Trichosanthes Decoction) as the primary formula. (Zhang Yuansu stated: All pain, itching, and sores belong to the Heart. Regardless of whether the fire pathogen is excess or deficiency, it should be discussed from the perspective of Heart Fire. If the Spleen is deficient, Liver Qi overacts; if Liver and Heart Fire combine, Gualou Tang is used. If the Spleen Earth is excess, and hyperactive Fire counter-overacts causing epilepsy, this is an excess pathogen. For constipation, use Xieqing Wan (Drain the Green Pill); for loose stools, use Xieqing Tang (Drain the Green Decoction). Pulse differentiation is also necessary.)
Gualou Tang (Formula see under Convulsive Disease of Infants section)
[Li Gao] In cases where convulsions occur before the eruption of pox/rashes, it is caused by external contraction of Wind-Cold pathogens and internal emergence of Heart Heat. One should administer Jiedu Wan (Detoxification Pill) with Tea Powder, or treat with Xijiao Dihuang Tang (Rhino Horn and Rehmannia Decoction).
[Worldly Physicians] When treating pox/rashes about to erupt, if the body is hot and restless with sudden惊厥 (convulsions/fright), use Qufeng Gao (Wind-Expelling Ointment) or Xiao Rusheng Yin (Small Like-Sage Drink). If urination is obstructed, use Bazheng San (Eight-Positive Powder). If there is excessive phlegm-saliva, use Lijing Wan (Phlegm-Expelling Pill) or Baolong Wan (Embracing Dragon Pill), administered according to symptoms.
[Zhu Zhenheng] Before the eruption of pox/rashes, if there is initial body heat, fright, jumping, and convulsions, this is not Fright-Wind (Jing Feng), but should be treated with diaphoretic (sweat-inducing) herbs.
[Worldly Physicians] Formula for Wind-Induced Convulsions in Smallpox/Measles
Renshen (Ginseng Radix et Rhizoma), Qianghuo (Notopterygii Rhizoma et Radix), Fangfeng (Saposhnikoviae Radix), Jiangcan (Bombyx Batryticatus), Nanting (Arisaematis Tuber processed with Ginger), Baifu (Typhonii Rhizoma processed with Ginger), Gancao (Licorice Root processed with honey).
Equal parts of the above, add three slices of Shengjiang (Fresh Ginger), decoct in water and take orally. The convulsions will stop immediately.
[Qian Yi] After the rash disease, if epilepsy is prone to develop, it is difficult for residual sores to cause epilepsy because Wood overacts on Spleen, and Wood returns to Heart. If it is Cold-Fright, use Liangjing Wan (Cooling Fright Pill); if it is Warm-Fright, use Fenhong Wan (Pink Pill, i.e., Wenjing Wan/Warming Fright Pill).
[Huoyou Xinshu] To treat pain from smallpox sores, use Wenjing Wan (Warming Fright Pill), dissolved in water and taken orally. (Formula see previous Convulsions section).
[Zhang Yuansu] To treat restlessness and pain after sores erupt, use Wuwu Muxiang San (Five-Ingredient Costus Powder).
Qingmuxiang (Costi Radix, 2 liang), Dingxiang (Caryophylli Flos, 1 liang), Linglingxiang (Lingzhi Xiang/Agarwood? Note: Linglingxiang usually refers to Agastache or similar aromatic, here likely distinct local herb, translated as Linglingxiang), Shexiang (Moschus, 1 fen), Baijian (Alumen, 1 liang).
Take 4 qian per dose, decoct in 1.5 small cups of water. For severe heat, add Xijiao (Rhinoceros Horn, 1 liang). If Xijiao is unavailable, substitute with Shengma (Cimicifugae Rhizoma). For mild cases, one dose yields great effect.
Another method: Mix Mangxiao (Mirabilite) with Pig Gallbladder bile, apply to sores to loosen them. When scabs fall off without scars, apply Yellow Earth (Huangtu) for good results. If this condition presents with astringent urination and blood, the middle is damaged (critical prognosis). If the back of the sores is black and sunken without pus, death is inevitable and untreatable.
[Worldly Physicians] When smallpox is about to form scabs, if they are dry, hard, and painful, apply Su (Butter/Ghee) to moisten them. If scabs can be removed, remove them. If Su is unavailable, use Zhu You (Pig Fat) boiled in water as a substitute. This type of pain cannot be avoided merely by taking medicine.
