行痹，是由风邪偏盛所致。风的特性是善于游走且变化迅速，因此其症状在身体上下左右各处流动，没有固定的停留点，随着病邪到达的部位，导致气血运行不畅而形成痹证。治疗虽然需要通行气血，但应主要以祛风的方剂为主。《灵枢·寿夭刚柔》篇中说：病位在阳分的称为风，病位在阴分的称为痹，阴阳都受病的，称为风痹。所谓风痹，是指阳邪侵入阴分的意思。所以，在治疗时既要驱散风邪，又必须兼用活血的方剂。还有血痹，是因为血虚而遭受风邪侵袭，也是由阳邪侵入阴分所导致的。这其实就是风痹的症状，如果从风的角度来说，就叫做风痹；从血的角度来说，就叫做血痹。如果是其他风病但没有侵入阴分的，那本来就不能称之为痹证了。
四妙散：治疗行痹引起的走窜疼痛。
威灵仙（用酒浸泡，焙干，五钱） 羯羊角灰（三钱） 苍耳子（一钱半） 白芥子（一钱，炒制）
研成细末，每次服用一钱匕，用姜汤送服。

当归 陈皮 麻黄 炙甘草 川芎 御米壳（罂粟壳） 丁香（各等分）
以上药物用慢火共同炒至黄色，每次服用三钱，加水煎煮后服用。
按语：麻黄药性猛烈，配合罂粟壳的收敛涩滞之性，就能使药力向内通达经络，不再向外发散到皮毛，因此能够治疗痹痛疾病。川芎、当归用来行血，陈皮、丁香用来行气，气血得以通畅，邪气自然去除，炙甘草则是用来调和药性、缓解急迫的作用。用慢火共同炒制，是为了让药物的气味融合，使它们不相排斥而相互协同。

Xing Bi (Wandering Bi Syndrome) is caused by the predominance of Wind pathogen. The nature of Wind is agile and prone to rapid changes; therefore, its symptoms wander up and down, left and right, without remaining fixed at any location. As the pathogen moves to different areas, it obstructs the flow of Blood and Qi, resulting in Bi syndrome. Although treatment involves promoting the circulation of Blood and Qi, it should primarily focus on formulas that dispel Wind. Furthermore, the chapter "Shou Yao Pian" (Chapter on Longevity and Shortness of Life) states: "Diseases located in Yang are named Feng (Wind); diseases located in Yin are named Bi; when both Yin and Yang are affected, it is named Feng Bi (Wind-Bi). 'Feng Bi' refers to the invasion of Yang pathogens into Yin." Thus, while dispersing Wind pathogens, one must also incorporate formulas that invigorate Blood. There is also Xue Bi (Blood Bi), which results from Wind attacking due to Blood deficiency, also caused by Yang pathogens invading Yin. This is essentially the same condition as Feng Bi; referred to from the perspective of Wind, it is called Feng Bi; referred to from the perspective of Blood, it is called Xue Bi. If other Wind diseases have not invaded Yin, they certainly cannot be classified as Bi syndromes.
Si Miao San (Four Marvels Powder): Treats wandering pain associated with Xing Bi.
Weilingxian (Caulis Clematidis) (soaked in wine, dried over low heat, 5 qian) Jieyangjiao Hui (Ash of Ram's Horn, 3 qian) Can'erzi (Fructus Xanthii, 1.5 qian) Baijiezi (Semen Sinapis Albae) (1 qian, stir-fried)
Grind into a fine powder. Take 1 qian bi per dose, administered with Ginger Decoction.
Ruyi Tongsheng San (Auspicious Universal Holy Powder): Treats wandering pain associated with Xing Bi.
Danggui (Radix Angelicae Sinensis) Chenpi (Pericarpium Citri Reticulatae) Mahuang (Herba Ephedrae) Zhigancao (Radix Glycyrrhizae Preparata) Chuanxiong (Rhizoma Chuanxiong) Yumiqiao (Pericarpium Papaveris) Dingxiang (Flos Caryophylli) (equal parts)
Stir-fry all ingredients together over slow fire until yellow. Take 3 qian per dose, decocted in water and taken orally.
Commentary: Mahuang is potent; combined with the astringent property of Yumiqiao (Papaver Pericarpium), its action is directed inward to the meridians rather than outward to the skin and hair, making it effective for treating Bi pain. Chuanxiong and Danggui serve to invigorate Blood; Chenpi and Dingxiang serve to promote Qi movement. When Qi and Blood circulate freely, pathogenic factors are expelled. Zhigancao is used to harmonize the formula and relieve urgency/spasm. Stir-frying them together over slow fire aims to blend their aromas and properties, ensuring they synergize rather than conflict.
Danxi’s Formula for Treating Wandering Pain in Bi Syndrome:
Cangzhu (Rhizoma Atractylodis Chinensis) Huangbai (Cortex Phellodendri) (each stir-fried with wine, 2 qian) Jiuweilingxian (Caulis Clematidis processed with wine) Baijiezi (Semen Sinapis Albae) Lingyangjiao Hui (Ash of Antelope Horn) (each 1 qian)
Add one slice of Shengjiang (Rhizoma Zingiberis Recens), decoct in water, and take orally.

Refine Zhu Zhi (Suet Porci) to remove impurities and form an ointment base. Mix in the medicinal powders evenly. Rub between palms until hot, then apply and massage onto the area of wandering pain. This method is highly effective.
