薛氏曰∶ 者，筋脉急而缩也； 者，筋脉缓而伸也。一缩一伸，手足相引，搐搦不已，与
婴儿发搐相似，谓之 也。此证多属风，盖风主摇动也。骆龙吉云∶心主脉，肝主筋，心属
火，肝属木，火主热，木主风，风火相炽，则为 也。治法，若因风热，（此风皆本内热，故
立方亦皆从内）用钩藤汤加柴胡、山栀、黄芩、白术，以平肝木，降心火，养气血；若风痰上
涌，加竹沥、南星、半夏；若风邪急搐，加全蝎、僵蚕，亏损气血，用八珍汤加钩藤、山栀为主。
若无力抽搐，戴眼反折，汗出如珠者，肝绝也，皆不治。一妊妇四肢不能伸，服祛风燥血之
剂，遗屎痰甚，四肢抽搐，余谓肝火血燥，用八珍汤加炒黑黄芩为主，佐以钩藤汤而安。后因
怒，前证复作，小便下血，寒热少寐，饮食少思，用钩藤散加山栀、柴胡而血止，用加味逍
遥散，寒热退而得寐，用六君子汤加芍药、钩藤钩，饮食进而渐安。
钩藤汤 方见胎动不安。
大全云∶孕妇不语，非病也。间有如此者，不须服药，临产月，但服保生丸、四物汤之类，
产下便语得，亦自然之理，非药之功也。医家不说与人，临月则与寻常之药，产后能语，则
以为医之功，岂其功也哉。
黄帝问曰∶人有重身，九月而喑，此为何也？岐伯对曰∶胞之络脉绝也。帝曰∶何以言
之？岐伯曰∶胞络者，系于肾，少阴之脉，贯肾，系舌本，故不能言。（亦肾气之不足）帝曰∶治
之奈何？岐伯曰∶无治也，当十月复。
薛氏说：瘛（chì，筋脉拘急收缩），是筋脉紧急而收缩；瘲（zhēng，筋脉弛缓伸展），是筋脉松弛而伸展。一缩一伸，手足相互牵引，抽搐不止，与婴儿发生惊风抽搐相似，称为瘛疭（chì zòng）。这种证候多属于风邪致病，因为风性主摇动。骆龙吉说：心主血脉，肝主筋脉，心属火，肝属木，火主热，木主风，风火相互炽盛，就会形成瘛疭。治疗方法：如果是因风热所致（这种风都源于内热，所以立方也都从内部调理），用钩藤汤加柴胡、山栀、黄芩、白术，以平抑肝木，清降心火，滋养气血；如果是风痰上涌，加竹沥、南星、半夏；如果是风邪引起的急骤抽搐，加全蝎、僵蚕；如果是气血亏损，用八珍汤加钩藤、山栀为主方。如果出现无力抽搐、戴眼（眼球固定向上凝视）、反折（身体向后角弓反张）、汗出如珠的症状，这是肝气绝的表现，都属于不治之症。有一位孕妇四肢不能伸展，服用祛风燥血的药剂后，出现遗屎、痰多，四肢抽搐，我认为这是肝火旺、血燥所致，用八珍汤加炒黑黄芩为主方，佐以钩藤汤而痊愈。后来因为发怒，前面的症状复发，小便下血，寒热往来，睡眠少，饮食减少，用钩藤散加山栀、柴胡而血止，用加味逍遥散，寒热退去而能入睡，用六君子汤加芍药、钩藤钩，饮食增进而逐渐安稳。
钩藤汤 方剂见胎动不安条下。
《大全》说：孕妇不说话，不是病。偶尔有这种情况的，不需要服药，到了临产月份，只要服用保生丸、四物汤之类的药物，产后就能说话，这也是自然之理，并非药物的功效。医生不告诉患者实情，临月时给服寻常药物，产后能说话，就认为是医生的功劳，这哪里是医生的功劳呢？
黄帝问道：人有身怀双胎（或指怀孕）的情况，到第九个月时失音，这是什么原因？岐伯回答说：胞宫的络脉阻滞不通。黄帝问：为什么这样说？岐伯说：胞络连接于肾，足少阴肾经贯穿肾脏，系连舌根，所以不能说话。（这也是肾气不足的表现）黄帝问：怎么治疗？岐伯说：不需要治疗，等到第十个月（分娩后）自然会恢复。
Xue said: Chi (chì, contraction of sinews and vessels) refers to the tightness and shortening of sinews and vessels; Zheng (zhēng, relaxation of sinews and vessels) refers to the laxity and extension of sinews and vessels. One contracting and one extending, with hands and feet pulling each other, and continuous convulsions, similar to infantile convulsions, is called Chi-Zong (chì zòng). This syndrome mostly belongs to Wind, as Wind governs tremors and movements. Luo Longji said: The Heart governs the vessels, the Liver governs the sinews; the Heart belongs to Fire, the Liver belongs to Wood; Fire governs Heat, Wood governs Wind. When Wind and Fire blaze together, Chi-Zong occurs. In terms of treatment methods: if caused by Wind-Heat (this Wind originates from internal Heat, so the prescriptions also address the interior), use Gouteng Tang (Uncaria Decoction) added with Chaihu (Bupleuri Radix), Shanzhi (Gardeniae Fructus), Huangqin (Scutellariae Radix), and Baizhu (Atractylodis Macrocephalae Rhizoma) to calm the Liver Wood, descend Heart Fire, and nourish Qi and Blood; if Phlegm-Wind surges upward, add Zhuli (Bambusa Textilis Sap), Nanting (Arisaematis Cum Bile), and Banxia (Pinelliae Rhizoma); if acute convulsions are caused by Wind pathogen, add Quanxie (Scorpio) and Jiangcan (Bombyx Batryticatus); if there is a deficiency of Qi and Blood, use Bazhen Tang (Eight-Treasure Decoction) added with Gouteng (Uncariae Ramulus cum Uncis) and Shanzhi as the main formula. If there are weak convulsions, Daiyan (eyes fixed upward), Fanze (opisthotonos), and sweating like pearls, this indicates Liver exhaustion, and all such cases are incurable. A pregnant woman had limbs that could not extend; after taking formulas for dispelling Wind and drying Blood, she suffered from fecal incontinence and profuse phlegm, with limb convulsions. I diagnosed it as Liver Fire and dry Blood, treated her mainly with Bazhen Tang added with stir-fried black Huangqin, assisted by Gouteng Tang, and she recovered. Later, due to anger, the previous symptoms recurred, with hematuria, alternating chills and fever, insomnia, and poor appetite. She was treated with Gouteng San added with Shanzhi and Chaihu, which stopped the bleeding; then Jiawei Xiaoyao San was used, which resolved the chills and fever and allowed sleep; finally, Liujunzi Tang added with Shaoyao (Paeoniae Radix Alba) and Gouteng Gou (Uncariae Ramulus cum Uncis) improved her diet and led to gradual recovery.
Gouteng Tang is listed under the section on Fetal Restlessness.
Daquan states: A pregnant woman's inability to speak is not a disease. Occasionally, this happens; medication is unnecessary. In the month before delivery, simply administering Bao Sheng Wan (Life-Preserving Pill) or Siwu Tang (Four-Substance Decoction) allows speech to return after childbirth. This is natural law, not the merit of medicine. Physicians do not disclose this truth to patients. They administer ordinary medicines near term; when the patient can speak postpartum, they claim credit for their medical skill. How can this be considered their merit?
The Yellow Emperor asked: There are cases where a person, while pregnant, loses their voice in the ninth month. What is the reason for this? Qibo replied: The collateral vessels of the uterus are obstructed. The Emperor asked: Why do you say so? Qibo said: The uterine collaterals connect to the Kidney. The Foot-Shaoyin Kidney channel penetrates the Kidney and connects to the root of the tongue; therefore, speech is impaired. (This is also due to insufficiency of Kidney Qi). The Emperor asked: How should it be treated? Qibo said: No treatment is needed. It will recover naturally in the tenth month.
