【论述】风腿的症状表现：四肢弛缓无力，无法收持；身体疼痛；肌肉虚胀；骨节松弛懈怠；腰部和脚部软弱无力；感觉迟钝，甚至不知痛痒。这是因为风邪侵入分肉（肌肉间隙），流注于血脉之中，导致营气和卫气稽留停滞，运行涩滞不畅，从而引起身体、骨节、肌肉、腰脚等处痹阻阻滞，无力且不能使用。若久治不愈，气血亏虚瘦弱，则会演变为水病（水肿）。

上三味药。先取杏仁二斗捣碎，再放入砂盆内烂研。逐渐加入水八斗，边研磨边绞汁，取尽汁液去渣。煎煮取四斗尝之，若味道香滑则说明已熟。倒入不透气的瓮中，按规定盖好密封，制成三份料酒的酒醅。
第一次酿制：取糯米六斗，蒸成饭。用曲末十二斤拌和。又取杏仁四升烂研，逐渐加入水一斗六升，煎取八升，温度适宜后，投入前面的药瓮中酝酿。使米粒糜烂溃散。

[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).

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.

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.

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.
