【荣斋按】本节俞氏所讲的“病因”，引申渊博，为全书中最突出的一篇。但由于头绪繁复，因而失去了重
心，把“伤寒类症的痉”与“伤寒变症的痉”混在一起。本篇章节，既然是“伤寒坏证”中的“伤寒转痉”，
则所述者，应该是“伤寒变症的痉”，而不是“伤寒类症的痉”了。这一点，吴坤安《伤寒指掌》里分析得比
较清楚，他说∶“如太阳未曾表汗而发痉，明系风湿之邪，混扰于太阳，风湿相持而不解，则湿热交并，留滞经

12. It is not only children who suffer from spasm; all cases of spasm are caused by fright. The symptoms present as fever, with or without sweating, the complexion alternating between cyanosis and erythema, somniloquy in dreams, and writhing movements of the hands and feet.
The appropriate prescription is Fumai Tang (Recover Pulse Decoction), removing Ren Shen (Ginseng Root), Gui Zhi (Cinnamon Twig), Gan Jiang (Dried Ginger), and Da Zao (Jujube Fruit), and adding Dan Shen (Salvia Miltiorrhiza Root), Mu Dan Pi (Moutan Cortex), and Xi Jiao (Rhinoceros Horn). This nourishes the substance of the Heart to regulate its function. For constipation, add Xuan Shen (Scrophularia Root); for loose stools, add Mu Li (Oyster Shell). If there is excessive sweating and spiritual unrest manifesting fear, add Long Gu (Fossilized Bones), whole Hu Po (Amber), and whole Zhu Sha (Cinnabar) (utilizing their qi rather than their substance). One must carefully inquire with the family to confirm a definite history of fright before applying this method. If the speech is disjointed and suspicious, one should calmly re-examine the patient to ascertain the true condition before administering medication. My son was three years old. On the ninth day of the sixth lunar month at Chen hour, he fell from a doorway. Shortly after, he developed fever followed immediately by spasms, unconsciousness, ice-cold extremities, and an imperceptible pulse. By Xu hour, the spasms ceased, but he remained febrile, comatose, and anhidrotic. The next morning, I administered Fumai Tang, removing Ren Shen, Gui Zhi, Gan Jiang, and Da Zao, one dose daily. After consuming three to four cups, he refused food and drink. At Si hour on the fourteenth day, he recovered through a shivering sweat (Zhan Han). Had we acted rashly during the state of spasm, convulsion, and coma, there would have been no hope for life. Generally, spasm and convulsion cause a reversal and chaos of Yin and Yang; even a slight mismatch renders it incurable. In their anxiety, families often administer drugs indiscriminately and perform acupuncture and moxibustion recklessly, resulting in countless deaths. According to Zhu Suisheng, spasm may cease spontaneously without treatment; thus, one need not focus solely on the spasm itself. Fever without sweating indicates purely an external contraction. From the ninth to the fourteenth day spans six days, coinciding exactly with the period when the meridian qi exhausts and resolves through sweating. Fumai Tang is not the correct treatment for this case. If treated with Ping Ying Yin Qiao Tang (Floating Duckweed and Honeysuckle Decoction), the disease would have resolved with a single dose. If the heat in the Pericardium is severe, characterized by dry lips and tongue and red streaks in the eyes, Niu Huang Qing Xin Wan (Calculus Bovis Clearing Heart Pill) is indicated. Ben Lun's Niu Huang An Gong Wan (Calculus Bovis Calming Palace Pill) and Zi Xue Dan (Purple Snow Pellet) can also be used酌情 (discretionarily). Wang Se stated that among the various conditions falsely transmitted as "Fright Wind," only this specific condition truly fits the name. Other types of fright due to wind or heat involve mental confusion where the patient is unaware of loud noises like drumming or cannon fire nearby. In contrast, Ke Wu (Hostile Influence) presents with mental fright and timidity, fearing strange people or clothing, making it easy to distinguish. Zhu Suisheng said that for spasm caused by Ke Wu, mild cases show only mental fright and timidity, while severe cases involve mental confusion. The seventeen-year-old son of Mr. Wang contracted spasm after being chased by a madman at night. He exhibited opisthotonos, rigid legs, closed Qi, cold limbs, and unresponsiveness to calls. Using Tong Qiao San (Unblocking Orifices Powder) insufflated into the nostrils, followed by water-ground Zi Jin Ding (Purple Gold Tablet)灌服 (administered orally), he recovered immediately.
(9) Spasm caused by self-disease of the Zang organs (this condition refers to twitching/convulsions). This condition arises because parents, fearing the child catches cold, cover them too heavily, dress them too warmly, or keep winter heated kang beds too warm, causing the child to sweat daily. Excessive sweating leads to blood loss, which shares the same principle as postpartum blood loss causing spasm. The Liver governs blood; sufficient blood ensures flexibility, while blood deficiency leads to rigidity. Hence, it is called self-disease of the Zang organ. This type of spasm is actually the root cause of spasm induced by the Six Evils. Since excessive sweating depletes blood (self-disease) and damages Wei Yang (defensive exterior yang), it predisposes one to contract the Six Evils. It relies entirely on enlightened physicians to thoroughly understand this principle and advise parents beforehand not to overheat children, thereby preventing endless illnesses unknowingly. This is what is meant by "treating disease before it arises." The treatment for self-disease of the Zang organs focuses on nourishing Yin and softening the Liver, identical to treating postpartum blood-loss-induced spasm. The principle is: when blood is sufficient, wind extinguishes itself. Fumai Tang, the three variants of San Jia Fumai Tang (Three Shells Recover Pulse Decoction), and the two formulas of Da Xiao Ding Feng Zhu (Great and Small Settling Wind Pearl) are all selectable. Zhuan Xi Gao (Special Gathering Paste) should be taken daily after spasms cease, divided into two doses of 4-5 qian, as a measure to replenish Yin for recovery. Cases of spasm due to Six Evils without sweating follow this example. For cases where Warm Disease or Heat Disease was mistakenly treated with sweating, one must first preserve Yin, unlike in Cold Damage where protecting Yang is urgent upon mistaken sweating. This is because Cold Damage deficiencies lie in Yang, whereas Warm Disease deficiencies lie in Yin.
[Bingzhang's Note] Shi's *Yi Yuan* contains a discussion on the syndrome differentiation and treatment of spasm, which offers significant insights. I record it for reference. Shi Feinan stated that laypeople do not understand the mechanism of the Six Qi causing disease, nor do they know that the Six Qi easily transform into Dryness, especially in children. Upon seeing a child with fever, regardless of the pathogen, they generally attribute it to Wind-Cold and prescribe acrid-warm ascending and dispersing herbs, mixed with bitter-warm and bitter-astringent digestive aids. This consumes body fluids, leading to spasm and twitching. Once spasm and twitching appear, it is labeled "Fright Wind," and doctors recklessly administer bitter-cold and harsh drugs like Bing Pian (Borneol), She Xiang (Musk), and minerals, claiming they open orifices, calm fright, clear heat, and dispel wind. Family pills and secret recipes are mostly like this, causing much mis-treatment. Others mistake "Jing" (Fright) for "Jin" (Sinew), performing sinew-piercing and blood-letting, or forcing massage. In wealthy families, the disaster accelerates. I have seen recommendations for doctors and prescriptions arriving continuously; one doctor uses hot herbs, another uses cold herbs. Within a day, seven prescriptions and ten doses are tried; knives, needles, and minerals are all applied. Or they summon ghosts and knock on gods, shaking and calling here and there, giving the child no peace. Heavy cotton and thick wadding, stove fires and hot pots, keep the child in heat. If a rational physician were summoned to treat according to the syndrome, how could it reach such an extreme? Generally, spasm is mostly due to Dryness-Heat transforming into Wind. Although named "Wind," it is actually a disorder of Liver Yang, where sinews lose nourishment, leading to rigidity. Briefly speaking: In early Wind-Cold, with fever and no sweating, whether spastic or not, treat with Acrid-Moistening methods, such as Xing Ren (Apricot Seed), Niu Bang Zi (Arctii Fructus), Jie Geng (Platycodon Root). If Cold is heavy, add Warm-Moistening agents like Cong Bai (Scallion White) and Sheng Jiang (Fresh Ginger). For Wind-Warmth and Warm-Heat, treat with Acrid-Cool methods, adding slightly bitter herbs to the Acrid-Moistening method, such as Sang Ye (Mulberry Leaf), Jiang Pi (Citrus Peel), Zhi Pi (Gardenia Bark), Lian Qiao (Forsythia Fruit), Zhe Pi (Sugarcane Peel), Li Pi (Pear Peel), and Sha Shen (Glehnia Root). If Heat is heavy, add cool-moistening light items like Yin Hua (Honeysuckle Flower), Ju Hua (Chrysanthemum Flower), Zhi Mu (Anemarrhena Rhizome), Ling Jiao (Antelope Horn), Zhu Ye (Bamboo Leaf), Lu Gen (Reed Rhizome), Li Zhi (Pear Juice), and Zhe Zhi (Sugarcane Juice). For Damp-Phlegm, add Ban Xia (Pinellia Tuber) and Mi Zhi Ju Hong (Honey-fried Tangerine Peel). For Heat-Phlegm, add Chuan Bei Mu (Fritillaria Bulb), Tian Zhu Huang (Calamus Bamboo Slurry), Gua Lou Shuang (Trichosanthes Powder), Hua Fen (Trichosanthes Root), and Dan Xing (Arisaema with Bile). For severe Dryness-Fire, Qing Zao Jiu Fei Tang (Clear Dryness Rescue Lung Decoction) is essential. For Dampness combined with Heat, add Acrid-Cool and Acrid-Bitter herbs like Kou Ren (Cardamom Seed), Tong Cao (Tetrapanax Pith), Fu Ling (Poria), Hua Shi (Talcum), Xian Zhu Ye (Fresh Bamboo Leaf), Xian He Ye (Fresh Lotus Leaf), Bian Dou Hua (Lablab Flower), and Jiang Chao Chuan Lian (Ginger-fried Coptis Rhizome). When Yin fluids are extremely depleted, with sallow complexion, dry orifices, no tears or nasal discharge, aphonia, quickly rescue the fluids using Xian Sheng Di (Fresh Rehmannia Root), Mai Dong (Ophiopogon Tuber), Xuan Shen (Scrophularia Root), Xian Shou Wu (Fresh Polygonum Multiflorum), E Jiao (Donkey-hide Gelatin), Ji Zi Huang (Egg Yolk), Xian Shi Hu (Fresh Dendrobium), Sheng Yu Zhu (Polygonatum Odoratum Rhizome), Nu Zhen Zi (Ligustrum Lucidum Fruit), Mu Li (Oyster Shell), and Gui Ban (Tartar Testudinis Carapax). When fluid deficiency and extreme dryness occur, one must continue the formula repeatedly; do not change the method midway, lest it become incurable.
Furthermore, Wang Xunchen's discussion on pediatric convulsions is essentially similar to twitching, i.e., Wu Jutong's concept of internal injury from diet causing spasm, commonly known as Slow Spleen Wind. Wang Qingren said, regarding convulsions: "When modern treatments fail, it is not because modern doctors are wrong, but because ancient formulas mislead. This condition often results from Cold Damage, Warm Epidemics, or prolonged diarrhea/vomiting from smallpox/rubella. Convulsions occurring late in the disease are named Slow Convulsive Wind. The name 'Slow Convulsive Wind' is linguistically awkward and fails to examine the disease source. If it were truly Wind, Wind entering the body must pass through skin and meridians, showing exterior-to-interior progression. Since there are no exterior signs of external contraction, why call it Wind? The term 'Wind' is used because during attacks, patients exhibit opisthotonos, upward-gazing eyes, locked jaw, drooling, phlegm rales in the throat, and coma, resembling Stroke. However, opisthotonos, limb convulsions, and clenched fingers indicate Qi deficiency failing to secure the limbs. Upward-gazing eyes and locked jaw indicate Qi deficiency failing to ascend. Drooling indicates Qi deficiency failing to return to its origin. Since Yuan Qi is deficient, it cannot reach the blood vessels; without Qi, blood stagnates and forms stasis. Treating a Qi-deficiency and Blood-stasis syndrome with Wind-dispersing and Fire-clearing formulas is erroneous. Wind-dispersing herbs scatter Qi when there is no Wind; Fire-clearing herbs coagulate Blood when there is no Fire. Follow-up attack/depletion formulas lead to Qi collapse and Blood exhaustion, making survival impossible. Experienced pediatricians rarely err because they see ancient formulas for convulsions are ineffective and abandon treatment upon seeing convulsions. Some recognize impending convulsions from current symptoms and warn families. Before convulsions occur, premonitory signs appear: sunken fontanelle, sleeping with eyes open, tongue trembling, inability to cry, crying without tears, flaring nostrils, phlegm rales, head drooping, silent locked jaw, cold limbs, foaming at the mouth, chest protruding like a bowl, rapid breathing, cyanotic-white complexion, profuse sweating, inability to suckle, green stool. (Green stool indicates Cold or Heat.) Empty rumbling in abdomen, lower diarrhea with upper cough, muscle twitching—all are precursors of convulsions. Among these twenty signs, not all need to be present; seeing one or two predicts future convulsions. Some are treatable, some are not. If eyes are open/upward, refusing food/cry, with phlegm-rales and panting, though severe, it is treatable. If the forehead is gray-black, testicles retract, or pulse is faint/thready/non-existent, though exterior signs are mild, it is incurable. Treatable cases should use Ke Bao Li Su Tang (Preserve and Establish Recovery Decoction): Sheng Huang Qi (Raw Astragalus Root) 1.5 liang, Dang Shen (Codonopsis Root) 3 qian, Bai Zhu (Atractylodes Macrocephala Rhizome) 2 qian, Gan Cao (Licorice Root) 2 qian, Dang Gui (Angelica Sinensis Root) 2 qian, Bai Shao (White Peony Root) 2 qian, Chao Zao Ren (Fried Ziziphus Seed) 3 qian, Yu Rou (Cornus Fruit) 2 qian, Gou Qi Zi (Goji Berry) 2 qian, Po Gu Zhi (Cibotium Rhizome) 1 qian, Tao He Rou (Peach Kernel Flesh) 1 piece. Decoct in water. This formula treats pediatric Qi deficiency from prolonged Cold Damage, epidemics, or smallpox/diarrhea, presenting with limb convulsions, opisthotonos, upward gaze, drooling, and coma. Dosages refer to a four-year-old; halve for two years, use one-third for one year, one-quarter for two-three months. Do not be rigid about dosage. I have used up to 2-3 doses in a day until convulsions stopped. Inform the family not to stop medication just because convulsions cease; continue several more doses until Qi is sufficient.
As noted, the aforementioned twenty-plus signs are all images of Deficient-Cold, hence salvageable. If Deficiency is complicated by Heat, it is difficult to treat. I treated a Ma family infant who developed spasm at one month old. Despite exterior-releasing and interior-purging therapies, mixed decoctions/pills, and acupuncture, spasms persisted, occurring dozens of times day and night. Examination showed left arm extended, right arm hanging down, clenched hands, oblique gaze, drooling, limb cramping, and slight fever. I prepared a decoction of Deng Cao (Juncus Effusus Stem), Bo He (Mint Herb), and Bai Mi (White Honey), added a little Jiang Zhi (Ginger Juice), ground Zi Jin Ding, and administered it. Spasms reduced by half. After further administration, fever subsided but spasms did not fully cease. Switching to Ke Bao Li Su Tang for two doses resulted in complete recovery.
[Rongzhai's Note] The "etiology" discussed by Yu in this section is profound and extensive, standing out as the most prominent part of the book. However, due to complex threads, it loses focus, mixing "Spasm as a Similar Syndrome of Cold Damage" with "Spasm as a Transformation Syndrome of Cold Damage." Since this chapter belongs to "Bad Syndromes of Cold Damage" specifically "Cold Damage Transforming into Spasm," it should describe "Spasm as a Transformation Syndrome," not "Spasm as a Similar Syndrome." Wu Kun'an's *Shanghan Zhizhang* analyzes this clearly: "If spasm occurs in Taiyang without prior sweating, it is clearly Wind-Damp pathogens disturbing Taiyang. Wind and Damp contend unresolved, leading to Wet-Heat merging and stagnating in meridians. Ying and Wei are disharmonious, fluids do not circulate, and sinews lose nourishment, causing spasm. This is a Similar Syndrome of Cold Damage, not a Transformation Syndrome. Symptoms include opisthotonos, head shaking, locked jaw, neck stiffness/tension, difficulty turning, fever in upper body/cold feet. Assess if Wind-Damp is heavy: with sweating, it is Soft Spasm; without sweating, it is Hard Spasm. If Cold Damage is over-treated with sweating, leading to spasm from excessive sweat, this is a Transformation Syndrome; treatments diverge. Excessive sweating dries blood, sinews lack nourishment, causing spasm. It is neither Damp nor Wind, so previous medicines should not be used recklessly. Thus, after Cold Damage sweating/purging, after abscess rupture, or postpartum, if body opisthotonos and limb cramps occur, it is mostly due to severe Qi/Blood deficiency and fluids failing to nourish sinews. Treatment uniformly uses Ba Zhen Tang (Eight Treasure Decoction) plus Gou Qi (Goji Berry), Chuan Duan (Dipsacus Root), Gou Teng (Uncaria Ramulus), and Gui Zhi (Cinnamon Twig) to nourish sinews. Do not treat purely as Wind." I consider this argumentation and treatment very reasonable; I wonder why Yu adopted this approach? Lianchen's commentary only cited Wu Jutong's nine major outlines of spasm and omitted Wu Kun'an's point, which must have a reason. Based on the intent of this section, I believe Yu's inclusion of Similar Syndrome spasm is inappropriate. These intuitive observations are submitted for discussion by scholars domestically.
