[Discussion] The manifestations of Wind Leg (Feng Tui) include: flaccidity and weakness of the four limbs, inability to hold or move them; body pain; distension and fullness of muscles; laxity and debility of bone joints; weakness of the waist and feet; dull sensation or even loss of proprioception. This is because Wind Pathogen invades the fenrou (intermuscular spaces), flows into the blood vessels, causing Qiying (Nutritive Qi) and Weiqi (Defensive Qi) to stagnate and remain in place, resulting in sluggish and obstructed circulation. Consequently, the body, bone joints, muscles, waist, and feet become bi-occluded (blocked by pathogenic factors), weak, and unusable. If not cured for a long time, with the depletion of Qi and Blood leading to emaciation, it may transform into Shuibing (Water Disease/Edema).
Formula for treating Wind Leg characterized by flaccidity and weakness of the four limbs, bone joint pain, skin numbness, muscle distension, heaviness of the waist and feet, and lack of strength in movement: Wujiapi Tang (Five-Acanthopanax Decoction).
Herbs: Wujiapi (Cortex Acanthopanacis), Bixie (Rhizoma Dioscoreae Hypoglaucae), Duhuo (Radix Angelicae Pubescentis) [remove rhizome head], Fangji (Radix Stephaniae Tetrandrae), Niuxi (Radix Achyranthis Bidentatae) [soaked in wine, sliced, and dried over heat, each 2 liang], Guizhi (Ramulus Cinnamomi) [remove rough bark], Chifuling (Poria with Red Core) [remove black skin], Yinyu (Fructus Ilicis Cornutae), Haitongpi (Cortex Erythrinae) [each 3 qian].
The above eighteen ingredients. Coarsely crush them like hemp seeds. Take 5 qianbi per dose. Add 1.5 zhan of water, one piece of fresh ginger (size of a jujube) smashed, decoct together until reduced to 0.7 zhan. Remove dregs and take warm, at any time.
Formula for treating Wind Leg characterized by flaccidity and non-retraction of the four limbs, edema of the face and body, laxity of sinews and bones, and skin numbness: Duhuo Tang (Angelica Pubescens Decoction).

The above fourteen ingredients. Crush them like hemp seeds. Take 5 qianbi per dose. Add 1.5 zhan of water, one piece of fresh ginger (size of a jujube) smashed, two jujubes split open. Decoct together to obtain 0.7 zhan. Remove dregs and take warm. Twice daily, once at night.
Formula for treating Wind Leg characterized by muscle distension, flaccidity and non-retraction of the four limbs, and bone joint pain: Fangfeng Tang (Saposhnikovia Decoction).
Herbs: Fangfeng (Radix Saposhnikoviae) [remove forked branches], Wujiapi (Cortex Acanthopanacis) [coarsely crushed], Fuzi (Radix Aconiti Lateralis Preparata) [processed until cracked, peel removed, umbilicus removed], Bixie (Rhizoma Dioscoreae Hypoglaucae), Yiyiren (Semen Coicis), Guizhi (Ramulus Cinnamomi) [remove rough bark, each 1 liang], Niuxi (Radix Achyranthis Bidentatae) [soaked in wine, sliced, and dried over heat], Duhuo (Radix Angelicae Pubescentis) [remove rhizome head], Chifuling (Poria with Red Core) [remove black skin], Danggui (Radix Angelicae Sinensis) [sliced and dried], Duzhong (Cortex Eucommiae) [remove rough bark, stir-fried], Haitongpi (Cortex Erythrinae).

Canger Tang soaking and washing formula for treating Wind Leg characterized by flaccidity and non-retraction of the four limbs:
Herbs: Cang'er (Fructus Xanthii) [5 sheng, seedlings are also acceptable], Yangtao (Caulis Actinidiae Polygamae) [4 sheng 2 he, finely crushed], Shuodiao (Caulis Siegesbeckiae) [cut, 2.5 sheng], Chixiaodou (Semen Phaseoli Angularis) [2.5 sheng], Shiyen (Sal) [appropriate amount].
The above five ingredients. Use 15 dan of water, boil down to 1 dan. Remove dregs and adjust temperature to suit. Soak the affected foot. Do not exceed the Juegu acupoint. Soak for the duration of one meal, then remove. Do not let the liquid cool; you may repeatedly add hot liquid to keep it warm. If sweating occurs all over the body, the disease will heal. Afterward, soak and wash every three days. Avoid external wind.
Bimajiu (Castor Bean Wine) for treating Wind Leg characterized by limb flaccidity, aphasia, and muteness:
Herbs: Bimazi You (Oleum Ricini) [1 sheng], Jiu (Alcohol) [1 dou].
The above two ingredients. Place together in a silver or earthenware vessel, stir well. Simmer in a double boiler for one day, stirring continuously. When ready, take 3 he per dose. On an empty stomach, once at midnight and once before sleep. Initially, vomiting of wind-phlegm saliva is expected; do not be alarmed. If no vomiting occurs, the phlegm has not been expelled.
Xingren Yunjiu (Almond Fermented Wine) for treating Wind Leg characterized by limb flaccidity, aphasia, and muteness:
Herbs: Xingren (Semen Pruni Armeniacae) [soaked in boiling water, peel and bitter kernels removed, 3 dou], Nuomi (Glutinous Rice) [1 shi, winnowed to remove chaff], Maiqu (Malt) [20 jin, dried over heat and ground into powder].
The above three ingredients. First, take 2 dou of Xingren, pound them, then grind thoroughly in a mortar. Gradually add 8 dou of water, grinding and squeezing juice continuously until all juice is extracted and dregs removed. Boil down to 4 dou. Taste it; if fragrant and smooth, it is cooked. Pour into a watertight urn, cover according to method, and prepare three batches of fermentation.
First Fermentation: Take 6 dou of glutinous rice, steam into rice. Mix with 12 jin of malt powder. Take 4 sheng of Xingren, grind thoroughly. Gradually add 1.6 dou of water, boil down to 8 sheng. When temperature is suitable, pour into the previous medicinal urn to ferment. Allow the rice to break down completely.
Second Fermentation: Take 2 dou of glutinous rice, steam into rice. Mix with 4 jin of malt powder. Take 3 sheng of Xingren, grind thoroughly. Gradually add 1.1 dou of water, boil down to 6 sheng. When temperature is suitable, pour into the previous urn.
Third Fermentation: Use rice, malt, and almond water juice, following the method of the Second Fermentation entirely.
After the three fermentations are complete, seal tightly with wax paper to prevent gas leakage. Store in a quiet place. Wait until fragrant and ripe. Take 5 he per dose, drink continuously at any time. Maintain a state of mild intoxication; avoid drunkenness and vomiting.
