《内经》曰∶诸痉（滑氏曰痉当作 ）项强，皆属于湿（王注云∶太阳伤湿也）。又曰∶诸暴强直，皆属于风（王注
云∶阳内郁而阴行于外也）。《原病式》曰∶筋劲强直而不柔和也。夫肝木属风而主筋，经曰诸暴强直属风，理宜然也。
其所谓诸 项强而属于湿者何欤？盖太阳经湿甚则兼风化，亢则害承乃制也。是故知 之为病，湿为本，风为标耳。故

Treatise
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: Various spasms (Jing, referring to tendon contraction), with stiffness of the neck and back, all belong to Dampness (Wang Bing's commentary explains: This is due to the Taiyang channel being injured by Dampness). It also states: Various sudden rigidities all belong to Wind (Wang Bing's commentary explains: This is because Yang Qi is constrained internally while Yin Qi circulates externally). Liu Wansu in his *Yuanbing Shi* (Original Treatise on Disease Mechanisms) states: Tendons are tense, rigid, and lack flexibility. The Liver belongs to Wood, corresponds to Wind, and governs the tendons. The Classics state that various sudden rigidities belong to Wind; this is logically consistent. Then what is the reason for those cases of neck stiffness belonging to Dampness? Generally speaking, when Dampness in the Taiyang channel is excessive, it transforms into Wind due to the principle that excess leads to harm and control brings balance. Therefore, knowing that this disease has Dampness as its root and Wind as its branch is crucial. Thus, Zhang Zhongjing divided this condition into Gang Jing (Rigid Spasm) and Rou Jing (Soft Spasm), which must be distinguished, as Gang Jing belongs to Yang and Rou Jing belongs to Yin. If there is fever in the Taiyang channel, without sweat and aversion to cold, with a string-taut, long, and forceful pulse, chest fullness, trismus (lockjaw), spasm of the hands and feet, teeth grinding, eyes open, and even convulsions or opisthotonos (body arched backward like a bow), this is called Gang Jing. If there is slight fever in the Taiyang channel, with profuse sweating and no aversion to cold, with a slow, choppy, string-taut, and fine pulse, inability to control the four limbs, frequent convulsions, closed eyes and mouth, this is called Rou Jing. Broadly speaking, this is caused by Wind and Dampness invading the Taiyang channel, with variations in severity. Cases where Wind predominance is greater are called Gang Jing, because Wind nature is rigid and urgent. Cases where Dampness predominance is greater are called Rou Jing, because Dampness nature is soft and gentle. Additionally, various deficiency patterns exist; exterior deficiency unable to withstand Wind-Cold can also cause this disease. Therefore, whether postpartum, after metal wounds, falls and bruises, or after abscesses ulcerate and drain pus, any condition involving excessive blood loss can lead to this disease. Here, deficiency is the root and Wind is the branch. There are also cases with absolutely no Wind pathogen that still cause tendon contraction and opisthotonos; this is because blood loss fails to nourish the tendons. Zhu Danxi strongly emphasized not treating this as Wind and using Wind-dispelling herbs, lest one dry up Yin Blood further leading to untreatable conditions. One must be cautious!
Pulse Diagnosis
The *Mai Jing* (Pulse Classic) states: In Taiyang disease with fever, if the pulse is deep and thin, it indicates Jing (Spasm).
The pulse comes, feeling pounding and string-taut upon pressure, moving straight up and down.
For patients with Jing, the pulse is deep, firm, and moves straight up and down.
In this disease, after inducing sweating, if the pulse becomes slippery and rapid like a snake, and abdominal distension occurs suddenly, it indicates impending resolution; if the pulse remains unchanged, becoming deep and string-taut, death is certain (the character "Jing" here is likely a typo for "Death").
In Taiyang disease, with complete symptoms, body stiffness, and a deep-slow pulse, this is Rou Jing (Soft Spasm), treated with Gualou Guizhi Tang (Trichosanthes Root and Cinnamon Twig Decoction).
Methods
Zhu Danxi said: Generally similar to Epilepsy (Xian), but more deficient than Epilepsy. It must not be treated as Wind, nor should Wind-dispelling herbs be used exclusively. It mostly belongs to Qi and Blood deficiency, accompanied by Fire and Phlegm. Treatment should involve tonification combined with descending Phlegm and Fire, using herbs such as Renshen (Ginseng), Baizhu (Atractylodes), Chuanxiong (Ligusticum), Danggui (Angelica), and Zhuli (Bamboo Sap).
One formula treats young people who develop Jing (Spasm) after acne/pox scabs fall off, presenting with trismus, rigid limbs, and occasional periumbilical abdominal pain causing cold sweat like rain, stopping when pain subsides. The pulse is extremely tight and string-taut, resembling a true string pulse. Previously, labor and fatigue damaged the Blood; after the pox, Blood was further depleted and Wind-Cold was contracted. Warm herbs to nourish Blood and acrid-cool herbs to disperse Wind should be used. Shaoyao (Peony) and Danggui (Angelica) as Sovereign herbs, Chuanxiong (Ligusticum), Qingpi (Citrus Peel), and Dengouteng (Uncaria) as Minister herbs, Baizhu (Atractylodes) and Gancao (Licorice) as Assistant herbs, Guizhi (Cinnamon Twig), Muxiang (Aucklandia), and Huanglian (Coptis) as Guide herbs, plus a little Honghua (Safflower), decocted in water and taken orally will cure.
(Above are two rules from Danxi)
Gualou Guizhi Tang (from *Lei Zheng Huo Ren Shu*) Treats Taiyang Cold Damage progressing to Rou Jing (Soft Spasm).
Gualou Gen (Trichosanthes Root), Gancao (Licorice, honey-fried, each 3 liang), Guizhi (Cinnamon Twig), Shaoyao (Peony), Shengjiang (Fresh Ginger, each 3 liang), Dazao (Jujube, 12 pieces).
Finely cut the above six ingredients. Take one dose, add 9 sheng of water, boil to obtain 3 sheng. Drink in three doses continuously to induce mild sweating. If sweat does not occur, drink hot porridge shortly after to promote sweating.
Gegen Tang (Pueraria Decoction, from *Lei Zheng Huo Ren Shu*) Treats Taiyang disease with no sweat, reduced urination, Qi rushing to the chest, trismus preventing speech, about to become Gang Jing (Rigid Spasm). (Formula see Shanghan Section.)
Mahuang Gegen Tang (Ephedra and Pueraria Decoction, from *Lei Zheng Huo Ren Shu*) Treats Gang Jing (Rigid Spasm), with no sweat and aversion to cold.
Mahuang (Ephedra), Chi Shaoyao (Red Peony, each 3 qian), Gan Ge (Kudzu Root, 4.5 qian), Douchi (Fermented Soybean, half he).
Finely cut, take one dose. Add 2 large zhan of water and 3 stalks of Congbai (Scallion White). Boil to 8/10 volume. Take warm.
Da Chengqi Tang (Major Order the Qi Decoction, from *Lei Zheng Huo Ren Shu*) Treats Gang Jing (Rigid Spasm) with solid heat in the intestines. (Formula see Shanghan Section.)
Guizhi Gegen Tang (Cinnamon Twig and Pueraria Decoction, from *Lei Zheng Huo Ren Shu*) Treats Rou Jing (Soft Spasm), with sweat and no aversion to cold. (Formula see Shanghan Section.)
Guizhi Gualou Gen Tang (Cinnamon Twig and Trichosanthes Root Decoction, from *Lei Zheng Huo Ren Shu*) Treats Rou Jing (Soft Spasm) generally. (Formula see Zhongfeng Section.)
Xiao Xuming Tang (Minor Continuation Life Decoction, from *Jin Gui Yao Lue*) Treats both Gang Jing (Rigid Spasm) and Rou Jing (Soft Spasm) generally. (Formula see Zhongfeng Section.)
Fangguang Danggui Tang (Saposhnikovia and Angelica Decoction) Treats cases of excessive sweating, fever, head shaking, trismus, and opisthotonos. Suitable for dispelling Wind and nourishing Blood.
Fangfeng (Saposhnikovia), Danggui (Angelica), Chuanxiong (Ligusticum), Shengdihuang (Rehmannia Root, each 2.5 qian).
Finely cut, take one dose, decoct in water and take orally.
Danggui Buxue Tang (Angelica Tonify Blood Decoction, by Li Dongyuan) Treats all conditions of excessive blood loss, where lack of Blood fails to nourish tendons, causing limb spasms and trismus resembling opisthotonos.
Huangqi (Astragalus, 1 liang), Danggui (Angelica, 5 qian, soaked in wine and washed clean).
Finely cut, take one dose. Add 2 zhan of water, boil to 1 zhan. Take warm. If complicated by Wind or Broken Injury Wind, add Fangfeng (Saposhnikovia) and Qianghuo (Notopterygium, each 1 qian), Jingjiesui (Schizonepeta Achenes, 1.5 qian), Gancao (Licorice, 0.5 qian), reduce Huangqi (Astragalus) by half, decoct and take.
Juqing Jubai San (Champion Ascending Defeated Powder, from *Lei Zheng Huo Ren Shu*) Treats new postpartum Blood deficiency causing Jing (Spasm); similarly for Wind-stroke fever after sweating.
Jingjiesui (Schizenepta Achenes, any amount, slightly stir-fried).
Grind into powder. Take 3-5 qian per dose. Externally use Da黄豆 Huangjuan (Yellow Soybean Sprouts), pour hot wine over them, remove sprouts, use the juice to mix with the powder for oral administration. The effect is miraculous.
(Danxi Huotao) states: The so-called Gang Jing (Rigid Spasm) and Rou Jing (Soft Spasm) of old should be discussed in terms of Excess and Deficiency, which is correct. One belongs to External Contraction, the other to Internal Injury. Those belonging to External Contraction are Gang Jing (Rigid Spasm), suitable for Mahuang Gegen Tang, Gualou Guizhi Tang, Xiao Xuming Tang; those interior are treated with Da Chengqi Tang and similar formulas. Those belonging to Internal Injury are Rou Jing (Soft Spasm), suitable for Buzhong Yiqi Tang, Bawu Tang, Siwu Tang and similar formulas. If one divides Gang and Rou based on Wind and Dampness for treatment, many doctors would err; now dividing treatment by Excess and Deficiency makes the principle clear and undeniable.
(Medical Case)
Mrs. Tao, over thirty years old, short and slender, weak constitution. After menstruation, she suddenly developed Jing (Spasm), with trismus, limb contraction, and opisthotonos. I knew she had excessive blood loss, allowing Wind Pathogen to enter via deficiency. I used Siwu Tang (Four Substances Decoction) added with Fangfeng (Saposhnikovia), Qianghuo (Notopterygium), Jingjie (Schizonepeta), and a small amount of Fuzi (Aconite) to unblock meridians. After two doses, the illness halved; after six doses, she was fully recovered.
