痉者，项背强，头动摇，口噤，背反张是也。此太阳伤风，复感寒湿所致。其有汗恶风
为柔痉；无汗恶寒为刚痉，加减小续命汤主之。然痉病有三阳经络之殊，有胃腑实热所致，
有三阴中寒所发，有内伤气血虚弱而发，不可不辨。假如头摇，口噤，背反张者，太阳痉也
头低视下，手足牵引，肘膝相 ，阳明痉也。若眼目斜视，一手一足搐搦者，少阳痉也。
又如口噤胸满，卧不着席，脚挛急，大便闭结不通，必 齿，此阳明胃腑实热所致，宜
用三一承气汤下之。又如发热，脉沉细，手足厥冷，冷汗自出者，为阴痉，风寒中于脏也，
附子理中汤加防风、肉桂主之。然也有内伤发痉者，病患肝血不足，血燥生风，目斜手搐，
逍遥散加人参、桑寄生主之。经云∶诸风掉眩，皆属于肝也。若脾虚木旺，反伤脾土，用
五味异功散，加柴胡、芍药、木香、钩藤之属。脾气郁结，用加味归脾汤。若大病后，或产
后，气血大虚，用十全大补汤加钩藤、桑寄生，如不应，急加附子。此治痉病之大法也。
伤寒病出现发热，头部出汗，小便不通畅，口渴想喝水浆的情况，这是郁热在体内，必然会导致身体发黄。适宜使用此方：栀子（三钱）、甘草（炙用，一钱）、黄柏（二钱），加水煎煮后服用。
身体黄色像橘子皮的颜色，腹部胀满，大便闭结不通的，可以使用泻下法。茵陈（三钱）、栀子（二钱）、大黄（二钱），加水煎煮后服用。小便应当像皂角汁一样黑红，过一夜后腹部胀满减轻，黄色从小便排出。
阴黄的病症，身体发冷，脉象沉细，这是太阴经中的寒湿所致，身体颜色像熏过的黄，不像阳黄那样明亮如橘子色。应当询问其小便是否通畅，如果小便不通畅，适宜使用本方（指前文提到的茵陈蒿汤类方）；如果小便自利（通畅），则主治方剂为茵陈术附汤。茵陈、白术、茯苓（各一钱五分）、猪苓、泽泻（各七分）、薄桂（五分），加水煎煮后服用。
茵陈（一钱）、白术（二钱）、附子（五分）、干姜（五分）、甘草（炙用，一钱）、肉桂（去皮，三分），加水煎煮后服用。
痉病，表现为颈项和背部僵硬强直，头部摇动，口部紧闭，背部向后反张。这是太阳经受风邪侵袭，又感受寒湿所致。如果有汗且怕风的，称为柔痉；无汗且怕冷的，称为刚痉，均用小续命汤加减治疗。然而痉病有涉及三阳经络的不同，也有由胃腑实热引起的，有三阴经中寒引发的，有因内伤导致气血虚弱而发作的，不可不加以辨别。假如出现头摇、口噤、背部反张的，是太阳痉。如果头低垂视下，手足牵引拘急，肘部和膝盖相互靠近的，是阳明痉。如果眼睛斜视，一只手和一只脚抽搐的，是少阳痉。又如口噤胸满，睡觉时背部不能着席，脚部挛急，大便闭结不通，必定磨牙，这是由阳明胃腑实热引起的，适宜使用三一承气汤攻下。又如发热，脉象沉细，手脚冰冷，冷汗自出的，属于阴痉，是风寒侵入脏腑所致，主治方剂为附子理中汤加防风、肉桂。然而也有因内伤引发痉病的，患者肝血不足，血燥生风，出现眼睛斜视、手部抽搐，主治方剂为逍遥散加人参、桑寄生。医经云：“各种风证导致的动摇眩晕，都归属于肝。”如果是脾虚木旺，反过来伤害脾土，使用五味异功散，加柴胡、芍药、木香、钩藤等药。脾气郁结，使用加味归脾汤。如果在大病之后，或产后，气血大虚，使用十全大补汤加钩藤、桑寄生，如果不见效，紧急加入附子。这是治疗痉病的大法。
In Taiyang cold damage (Taiyang Cold Damage), characterized by fever, sweating only on the head, dysuria (difficult urination), and thirst for fluids, this indicates stagnant heat trapped within the interior, which will inevitably lead to jaundice. The appropriate formula is: Gardenia Fruit (Zhi Zi, 3 qian), Licorice Root (Gan Cao, roasted, 1 qian), Phellodendron Bark (Huang Bo, 2 qian). Decoct in water and take orally.
When the body exhibits a yellow color resembling orange peel, accompanied by abdominal fullness and constipation, purgation may be employed. The formula consists of: Yin Chen Hao (Artemisiae Scopariae Herba, 3 qian), Gardenia Fruit (Zhi Zi, 2 qian), Rhubarb Radix et Rhizoma (Da Huang, 2 qian). Decoct in water and take orally. The urine should resemble soap pod juice; after one night, abdominal distension will subside, and the jaundice will exit via the urine.
The syndrome of Yin Jaundice presents with a cold body and a deep, fine pulse, indicating cold-dampness in the Taiyin meridian. The skin appears dull yellow like smoked tobacco, unlike the bright orange-yellow hue of Yang Jaundice. One must inquire whether urination is difficult or free. If urination is difficult, the aforementioned formula (Yin Chen Hao Tang) is suitable; if urination is free, the primary formula is Yin Chen Zhu Fu Tang. Ingredients: Yin Chen Hao (3 qian), Atractylodes Macrocephala Rhizome (Bai Zhu, 2 qian), Aconite Lateralis Radix Praeparata (Fu Zi, 0.5 qian), Dried Ginger (Gan Jiang, 0.5 qian), Licorice Root (Gan Cao, roasted, 1 qian), Cinnamon Twig (Rou Gui, peeled, 0.3 qian). Decoct in water and take orally.
Spasm (Jing) is characterized by stiffness and rigidity of the neck and back, head tremors, trismus (locked jaw), and opisthotonos (backward arching of the back). This results from Wind invasion of the Taiyang channel compounded by Cold-Dampness. If there is sweating and aversion to wind, it is termed Flexible Spasm (Rou Jing); if there is no sweating and aversion to cold, it is termed Stiff Spasm (Gang Jing). Both are treated with Modified Xu Ming Tang. However, spasm syndromes differ by involvement of the three Yang meridians, or may arise from excess heat in the stomach fu organs, cold in the three Yin meridians, or deficiency of Qi and Blood due to internal injury; these distinctions must not be overlooked. For instance, head tremors, trismus, and opisthotonos indicate Taiyang Spasm. If the head is lowered with downward gaze, limbs are pulled and restricted, and elbows and knees touch, it indicates Yangming Spasm. If eyes deviate sideways and one arm and leg convulse, it indicates Shaoyang Spasm. Furthermore, if there is trismus, chest fullness, inability to lie flat (opisthotonos so severe the back does not touch the bed), calf cramps, constipation, and teeth grinding, this is caused by excess heat in the Yangming stomach fu organ, and San Yi Cheng Qi Tang should be used to purge. If there is fever, deep and fine pulse, cold extremities, and spontaneous cold sweat, it is Yin Spasm, caused by Wind-Cold invading the zang organs, treated with Fu Zi Li Zhong Tang plus Saposhnikovia Root (Fang Feng) and Cinnamon Bark (Rou Gui). There are also cases of spasm due to internal injury where Liver Blood is insufficient, leading to dry blood generating Wind, presenting with deviated eyes and hand convulsions, treated with Xiao Yao San plus Ginseng Radix (Ren Shen) and Taxillus Herba (Sang Ji Sheng). The Classic states: "All wind syndromes involving tremors and vertigo belong to the Liver." If Spleen deficiency leads to hyperactive Wood attacking Earth, use Wu Wei Yi Gong San plus Bupleurum Root (Chai Hu), Peony Root (Shao Yao), Aucklandiae Radix (Mu Xiang), and Uncaria Ramulus cum Uncis (Gou Teng). If Spleen Qi is constrained, use Jia Wei Gui Pi Tang. After severe illness or postpartum, when Qi and Blood are severely deficient, use Shi Quan Da Bu Tang plus Gou Teng and Sang Ji Sheng; if ineffective, urgently add Fu Zi. This constitutes the general principles for treating spasm syndromes.
