大全云∶妊娠体虚受风，而伤太阳之经络，后复遇风寒相搏，发则口噤背强，名之曰
痉。又云痉，其候冒闷不识人，须臾自醒，良久复作，谓之风痉，一名子痫，一名子冒，甚则反张。
薛氏曰∶前证若心肝风热，用钩藤汤；肝脾血虚，加味逍遥散；肝脾郁怒，加味归脾汤；
气逆痰滞，紫苏饮；肝火风热，钩藤散；脾郁痰滞，二陈、姜汁、竹沥。若兼证相杂，当参照子
烦门。
丹溪治一妇人，怀妊六月发痫，手足扬直，面紫黑色，合眼涎出，昏愦不省人事，半时
而醒，医与震灵丹五十余帖，其疾时作时止，无减证，直至临产方自愈，产一女，蓐中子母
皆安。次年其夫疑丹毒必作，求治之，诊其脉，浮取弦，重取涩，按至骨，则沉实带数，时正二
月，因未见其痫发症状，未敢与药，意其旧年痫发时乃五月，欲待其时，度此疾必作，当审
证施治。至五月半，其疾果作，皆是午巳两时，遂教以自制防风通圣散，用甘草，加桃仁多红
花少，或服或呕，至四五十剂，疾渐疏而轻，后发为疥而愈。（以防风通圣散、桃仁、红花治之
者，为浮为风，弦为饮，涩为瘀血，沉实为有余，数为热也，观发疥而愈，知此药之妙）

The *Daquan* records: When a pregnant woman has a weak constitution and is affected by wind pathogen, damaging the meridians and collaterals of the Taiyang (Greater Yang) channel, and subsequently encounters a struggle between wind-cold pathogens, the onset presents with lockjaw and stiffness of the back, termed "Jing" (Spasm). It is further stated that the manifestation of "Jing" includes dizziness, stuffiness, and loss of consciousness, followed by spontaneous recovery after a moment, only to recur after a while. This is called "Feng Jing" (Wind Spasm), also known as "Zi Xian" (Eclampsia of Pregnancy), or "Zi Mao" (Pregnancy Dizziness). In severe cases, it manifests as opisthotonos (backward arching of the body).
Xue Shi (Xue Ji) stated: For the aforementioned conditions, if caused by Wind-Heat in the Heart and Liver, use Gouteng Tang (Uncaria Decoction); if due to Blood Deficiency in the Liver and Spleen, use Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder); if due to Depression and Anger in the Liver and Spleen, use Jia Wei Gui Pi Tang (Modified Restore the Spleen Decoction); if due to Rebellious Qi and Phlegm Stagnation, use Zisu Yin (Perilla Infusion); if due to Liver Fire and Wind-Heat, use Gouteng San (Uncaria Powder); if due to Spleen Depression and Phlegm Stagnation, use Er Chen Tang (Two-Cured Decoction) with added Ginger Juice and Bamboo Sap. If complicated symptoms are mixed, treatment should refer to the section on "Zi Fan" (Pregnancy Restlessness).
Danxi treated a woman who suffered from epilepsy at six months of pregnancy. Her limbs extended and waved, her face was purple-black, she closed her eyes and drooled, and fell into a coma without consciousness. She woke up after half an hour. The physician administered fifty-plus doses of Zhen Ling Dan (Vibrating Spirit Pill), but the disease came and went without reduction in severity, only resolving spontaneously upon delivery. A daughter was born, and both mother and child were safe postpartum. The following year, her husband suspected a recurrence of carbuncle-toxin and sought Danxi's treatment. Danxi palpated her pulse: superficially it was Wiry (Xian), deeply it was Choppy (Se), and pressing to the bone revealed a Deep (Chen), Excess (Shi) quality with a Rapid (Shu) rate. It was the second month of the year. Since no epileptic symptoms were observed at that time, he dared not administer medicine immediately. He reasoned that her previous episode occurred in the fifth month; he waited for that time, anticipating the disease would recur, so he could examine the syndrome and treat accordingly. By mid-fifth month, the disease indeed manifested, occurring specifically during the Wu (11 AM–1 PM) and Si (9 AM–11 AM) hours. He then instructed her to take his self-formulated Fangfeng Tongsheng San (Saposhnikovia Decoction for Unblocking and Resolving), using Licorice Root (Gancao), increasing the dosage of Peach Kernel (Taoren), and decreasing the dosage of Safflower (Honghua). Whether taken orally or inducing vomiting, after forty to fifty doses, the disease gradually became less frequent and milder. Eventually, she developed scabies (skin sores) and was cured. (The rationale for using Fangfeng Tongsheng San, Taoren, and Honghua is that a Floating pulse indicates Wind, a Wiry pulse indicates Fluid retention, a Choppy pulse indicates Blood stasis, a Deep and Excess pulse indicates Pathogenic excess, and a Rapid pulse indicates Heat. Observing her cure through the eruption of scabies reveals the efficacy of this formula.)
Lingyangjiao San (Antelope Horn Decoction): Treats pregnancy-related dizziness, stuffiness, and opisthotonos, named Zi Xian Feng Jing (Eclamptic Wind Spasm).
Ingredients: Antelope Horn (Lingyangjiao, sliced), Angelica Pubescens (Duhuo), Sour Jujube Seed (Suanzaoren, stir-fried), Acanthopanax Bark (Wujiapi), Coix Seed (Yiyiren, stir-fried), Saposhnikovia Root (Fangfeng), Chinese Angelica Root (Danggui, soaked in wine), Szechwan Lovage Rhizome (Chuanxiong), Spirit-calming Poria (Fushen, woody core removed), Apricot Seed (Xingren) [each 5 fen], Costus Root (Muxiang), Licorice Root (Gancao) [each 2 fen].
Preparation: Coarsely crush the herbs, add five slices of fresh ginger, decoct in water, and take orally.
Gegen Tang (Kudzu Decoction): Treats pregnancy near term where Wind Spasm occurs, causing sudden stupor, loss of consciousness, vomiting, dizziness, and falling, with brief recovery followed by recurrence, named Zi Xian (Eclampsia).
Ingredients: Kudzu Root (Gegen), Fritillaria Bulb (Beimu, heart removed), Moutan Bark (Mudanpi), Saposhnikovia Root (Fangfeng), Chinese Angelica Root (Danggui), Szechwan Lovage Rhizome (Chuanxiong), Cinnamon Twig (Guigui), White Poria (Baifuling), Alisma Tuber (Zexie), Licorice Root (Gancao) [each 2 liang], Angelica Pubescens (Duhuo), Gypsum (Shigao, crushed), Ginseng (Renshen) [each 3 liang].
Preparation: Coarsely crush the herbs. Take 8 qian per dose, decoct in water, and take orally. Beimu facilitates easy delivery; if not near term, substitute with Cimicifuga Rhizome (Shengma) [a substitution many do not believe in]. Avoid consuming Seaweed (Haizao), Chinese Cabbage (Songcai), and Vinegar products. This formula contains Guizhi (Cinnamon Twig) and Mudanpi, making it less safe than Lingyangjiao San.

Ingredients: Ligusticum Chuanxiong Rhizome (Xiongnu), Notopterygium Rhizome (Qianghuo) [equal parts].
Preparation: Coarsely chop, decoct in water, add a small amount of wine, and take warm.
Qianghuo Jiu (Notopterygium Wine): Treats Wind-Stroke Spasm in pregnancy, presenting with lockjaw, limb rigidity, and opisthotonos. (This formula is excellent and can be used for various miscellaneous conditions).
Ingredients: Notopterygium Rhizome (Qianghuo, rhizome removed, 1.5 liang), Saposhnikovia Root (Fangfeng, rhizome removed, 1 liang), Black Soybean (Heidou, 1 he, skin removed).
Preparation: Coarsely crush the first two ingredients. Soak in 5 sheng of good wine overnight. For each dose, take 1 he of black soybeans, stir-fry until hot, pour into one large cup of the medicinal wine, boil briefly, then remove from heat. Strain the dregs, divide into two doses, and administer forcibly.
