颤，摇也。振，动也。风火相乘，动摇之象，比之螈 ，其势为缓。《内经》云∶诸风掉眩，皆属于肝。
掉即颤振之谓也。又曰∶诸禁鼓栗，如丧神守，皆属于热。鼓栗亦动摇之意也。此症多由风热相合，亦有风寒
所中者，亦有风挟湿痰者，治各不同也。（常见此症多于伤寒，热病痢疾中兼见者，多是热甚而然，虚亦有之。

颤，是摇动的意思。振，是抖动的意思。风与火相互搏结，呈现出动摇之象，相较于抽搐（筋脉拘急、手足伸缩），其病情较为缓和。《黄帝内经》说：“各种风病引起的肢体震颤和头晕目眩，都归属于肝脏。”这里的“掉”指的就是颤和振。又说：“各种牙关紧闭、鼓颔战栗，如同丧失神志控制的症状，都归属于热邪。”鼓颔战栗也是动摇的意思。这种病症多由风热相合所致，也有因风寒侵袭的，还有风邪挟带湿痰的，治疗方法各不相同。（临床上常见此症多于伤寒、热病、痢疾中兼见，多是热邪极盛所致，也有因虚证引起的。背部战摇、振动轻微且肢体灵活不痿弱，与中风导致的牵引牵动、沉重迟缓者，有细微的不同。）

Tremor refers to shaking. Convulsion refers to trembling. The mutual interaction of Wind and Fire presents the image of shaking; compared to convulsions (spasmodic contraction of muscles with extension and flexion of limbs), its intensity is milder. The *Neijing* states: "All wind diseases characterized by tremors, dizziness, and vertigo belong to the Liver." Here, "diao" refers to tremors and convulsions. It also states: "All cases of jaw clenching, shivering, and chattering teeth, resembling a loss of spiritual control, belong to Heat." Shivering and chattering teeth also imply shaking. This syndrome is mostly caused by the combination of Wind and Heat, but can also result from Cold-Wind invasion or Wind carrying Phlegm-Dampness; thus, treatments vary accordingly. (Clinically, this syndrome is often seen concurrently in Shanghan [Cold Damage], febrile diseases, and dysentery, mostly due to extreme Heat, though deficiency patterns also occur. Back trembling and shaking are mild with flexible limbs without flaccidity, which differs slightly from the heavy, sluggish traction and movement seen in Stroke.)
Xingfu San treats Stroke where the patient can speak, has no facial deviation, but experiences traction and twitching of the hands and feet.
Arisaema Cum Bile (Tiannanxing), Pinellia Rhizome Preparatum (Banxia) (both processed with ginger), Ginseng Radix et Rhizoma (Renshen), Aconitum Lateralis Radix Praeparata (Hei Fuzi) (skin and lateral root removed), Hydrastis Rhizoma (Baifuzi), Poria (Fuling), Aconitum Carmichaelii Radix (Chuanwu) (skin and lateral root removed), Bombyx Batryticatus (Jiangcan), Myrrha (Moyao) (equal parts).
Crush the herbs into coarse powder. Take 5 qian per dose, decoct with one cup of water and one cup of wine until reduced to 80%, take hot, and induce sweating as the goal.
Duhuo San (see previous section on Postpartum Convulsions).
[From *Qianjin Fang*] Jinya Jiu treats chronic Eight Winds and Five Zhu [infectious diseases], whole-body traction and twitching, limping gait, and inability to grasp or control movements.
Jinya (crushed like rice grains, placed in a small silk bag), Kochia Scoparia Herb (Difuzi) (if seeds are unavailable, use stems and leaves; another formula uses Cnidium Monnieri Fruit (Shechuangzi)), Prepared Rehmannia Root (Shudi), Polygonum Sieboldii Root (Shuodigu), Aconitum Carmichaelii Radix (Fuzi), Saposhnikovia Root (Fangfeng), Asarum Root (Xixin), Maogcao (each 4 liang), Sichuan Pepper (Chuanjiao) (4 he), Notopterygium Rhizome et Radix (Qianghuo) (1 jin).
Another formula uses Angelica Pubescens Root (Duhuo).
Crush the above ten ingredients into coarse powder, place in a silk bag, soak in 4 dou of wine in a porcelain vessel, seal tightly to prevent gas leakage. Soak for 3-4 nights in spring/summer, 6-7 nights in autumn/winter. Once the wine is ready, filter out the dregs. Take 1 ge daily, ensuring continuous wine effect. If one dose is not exhausted, the disease will surely be cured.
Postpartum convulsions due to deficiency and Wind invasion are similar to exterior injury syndromes; if the pathogen has not entered the interior, Fengfang Tang should be taken. (See previous section on Wind Gate.)
