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。
背战摇振动轻利而不痿弱，比之中风 曳牵动重迟者，微有不同。）

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.)
