病因源于气血虚弱，受到风寒湿毒之邪气侵袭，邪气与血液并行于皮肤腠理之间，邪气盛而正气衰。因此气血运行涩滞，涩滞则导致痹证，虚弱则导致痿弱，所以出现痹弱症状。（出自第十三卷中）
《肘后备急方》治疗香港脚（脚气病）的方法：此病最初起源于岭南地区，后来逐渐传播到江东地区。发病没有明显的渐进过程，有时只是轻微感到疼痛和麻木，或者两小腿感觉胀满，或者行走时突然腿脚弯曲无力。
如果病情紧急，先取优质豆豉一斗，经过三次蒸制、三次晒干，用优质酒三斗浸泡三个夜晚，然后就可以饮用，根据患者体质决定饮用量，最好预先制作好。
如果来不及等待浸泡，就用酒煮豆豉给患者饮用，并将药渣敷在脚上，这样病情可以得到轻微缓解，然后再配制其他药酒及膏汤进行炙烤治疗。（文仲《备急方》内容相同）
又有独活酒方。
以上两味药。用酒一斗，浸泡三个夜晚，从服用一合开始，以身体出现轻微麻痹感为度。忌食猪肉和冷水。（文仲《备急方》内容相同）

以上两味药。用水五升，先煮牛乳和水至五升，然后加入硫黄煎取三升，每次服用三合。也可以直接用牛乳煎煮硫黄，不用加水。如果没有牛乳，羊乳也很好。（《千金翼方》记载：一次服用一合无效，增至三合）
又有另一方。
先煎煮牛乳三升，使其减半，用五合送服硫黄粉末一两，服药完毕后，严密覆盖以促使出汗，不要让风吹到。中间再服一次，到了傍晚再服一次。如果已经出汗就不再服用，只需安心调养护理；如果未痊愈，几天后也可以再制作服用；如果长期服用……
《千金方》松脂散，主治各种风邪，以及大风引起的脚弱、风痹等症，熏陆法也相同。
取松脂三十斤，用棕皮袋装好，系紧袋口，铁锅底部铺上竹木，将袋子放在上面，用石头压住，往锅中加水至满，煮它，直到膏状物完全浮出，之后继续煮二十沸；接取药液置于冷水中，更换袋子清洗铁锅，再次如此煮九遍，药即制成。

The etiology stems from the deficiency of Qi and blood, where pathogenic factors of wind-cold-dampness-toxicity invade. The pathogens travel alongside the blood in the skin and interstices (skin pores and connective tissue), causing an excess of evil Qi and a scarcity of healthy Qi. Consequently, the flow of Qi and blood becomes stagnant; stagnation leads to Bi syndrome (obstruction syndrome characterized by pain or numbness), and deficiency leads to weakness, thus resulting in Bi-weakness symptoms. (From Volume 13)
*Zhouhou Beiji Fang* (Emergency Prescriptions Kept Up the Sleeve) treats Hongxiangjiao (Foot Qi disease): This disease initially originated in the Lingnan region and gradually spread to the Jiangdong region. It appears without gradual onset; sometimes there is only slight pain and numbness, or a feeling of fullness in both calves, or sudden flexion and weakness when walking.
If the condition is urgent, first take one *dou* of high-quality fermented soybeans (Douchi). Steam them three times and sun-dry them three times. Soak them in three *dou* of fine wine for three nights, then drink as tolerated according to the patient's constitution. It is best to prepare this in advance.
If waiting for soaking is not possible, boil the fermented soybeans in wine and have the patient drink it. Apply the dregs to the feet. This will slightly alleviate the condition, after which other medicated wines, pastes, and soups can be prepared for moxibustion or heat therapy. (Same content as Wen Zhong's *Beiji Fang*)
Another formula: Duhuo Wine.
*Duhuo Radix* (Wu Liang, sliced) *Fuzii Lateralis Radix Preparata* (Wu Liang, raw, peeled, broken)
These two ingredients are soaked in one *dou* of wine for three nights. Start taking one *ge*, increasing until a slight numbing sensation is felt. Avoid pork and cold water. (Same content as Wen Zhong's *Beiji Fang*)
Another formula:
High-quality Sulfur (Liang Er, powdered) Bovine Milk (Wu Sheng)
These two ingredients: Add five *sheng* of water to the milk and boil until reduced to five *sheng*. Then add the sulfur and decoct to obtain three *sheng*. Take three *ge* per dose. Alternatively, decoct the sulfur directly in milk without water. If bovine milk is unavailable, ovine milk is also effective. (*Qianjin Yifang* records: if one *ge* is ineffective, increase to three *ge*).
Another formula:
First decoct three *sheng* of bovine milk until it is halved. Take one *liang* of sulfur powder with five *ge* of the reduced milk. After taking the medicine, cover tightly to induce sweating, avoiding exposure to wind. Administer another dose midway, and one more dose at dusk. If sweating has already occurred, do not administer further doses; instead, provide careful nursing and care. If not cured, it may be prepared again after a few days. If taken long-term...
*Qianjin Fang* Songzhi San (Pine Resin Powder) treats all types of wind pathogens, as well as severe wind causing foot weakness and wind-Bi. The fumigation method is the same.
Take thirty *jin* of pine resin (Songzhi). Place it in a brown palm fiber bag, tie the top securely. Lay bamboo and wood at the bottom of an iron cauldron, place the bag on top, and press it down with stones. Fill the cauldron with water and boil. Continue boiling until the resin floats out completely, then boil for twenty additional boils. Collect the liquid and place it in cold water. Replace the bag and wash the cauldron, repeating this process nine times. The medicine is now ready.
Su Gong's Decoction Powder treats Hongxiangjiao during spring, summer, and autumn, characterized by foot weakness or swelling, rebellious Qi rushing to the heart, and body numbness and oppression.
*Duhuo Radix* *Poria* *Achyranthis Bidentatae Radix* *Stephaniae Tetrandrae Radix* *Atractylodis Macrocephalae Rhizoma* *Astragali Radix* *Ephedrae Herba* (nodes removed) *Bupleuri Radix* (each Liu Liang) *Angelicae Sinensis Radix* *Saposhnikoviae Radix* *Citri Reticulatae Pericarpium* (sliced) *Zingiberis Rhizoma Recens* *Prunus Armeniacae Semen*
The above twenty-two herbs do not have fixed dosages; they can be adjusted according to circumstances. The remaining twenty herbs are cut into bean-sized pieces and divided into thirty packets. Each packet is combined with one *liang* of fresh ginger and crushed tangerine peel.
Take cold. For chest oppression...
Stop taking the medicine when the illness subsides; do not take it regularly. Avoid pork, cold water, mutton, maltose syrup, raw green onions, peaches, plums, sparrow meat, and vinegar products. (From Volume 1)
Another regular decoction powder for treating various cases of Hongxiangjiao weakness that have not yet severely manifested.
*Duhuo Radix* *Stephaniae Tetrandrae Radix* *Ephedrae Herba* (nodes removed) *Poria* *Salviae Miltiorrhizae Radix* *Achyranthis Bidentatae Radix* (each Liu Liang) *Magnetitum* (Shi Liu Liang, crushed) *Astragali Radix* *Saposhnikoviae Radix* *Ginseng Radix* *Rhinocerotis Cornu* (each Liu Liang) *Cimicifugae Rhizoma* *Ligustici Chuanxiong Rhizoma* *Cinnamomi Ramulus* (each Si Liang) *Gypsum Fibrosum* (Shi Si Liang, crushed) *Evodiae Fructus* (Ba Liang) *Zingiberis Rhizoma Recens* *Pinelliae Tuber* (washed) *Arecae Semen* (large ones) *Prunus Armeniacae Semen* *Rhei Radix et Rhizoma* (sliced)
The above twenty-one herbs: Crush and slice sixteen of them into bean-sized pieces. Divide into thirty portions. Mix evenly for one dose. Take with three Areca nuts and one *liang* of fresh ginger.
Vomiting stops.
