凡肩痛、臂痛、腰疼、腿疼，或周身疼痛，总名曰痹症。明知受风寒，有温热发散药不
愈，
云∶病在皮脉，易于为功，病在筋骨，实难见效。因不思风寒湿热入皮肤，何处作痛。入于
气管，痛必流走；入于血管，痛不移处。如论虚弱，是因病而致虚，非因虚而致病。总滋阴
，外受之邪，归于何处？总逐风寒，去湿热，已凝之血，更不能活。如水遇风寒，凝结成冰
，冰成风寒已散。明此义，治痹症何难。古方颇多，如古方治之不效，用∶
秦艽（一钱） 川芎（二钱） 桃仁（三钱） 红花（三钱） 甘草（二钱） 羌活（一钱） 没药
（二钱） 当归（三钱） 灵脂（二钱，炒） 香附（一钱） 牛膝（三钱） 地龙（二钱，去土）
若微热，加苍术、黄柏；若虚弱，量加黄 一二两。
方歌
身痛逐瘀膝地龙，羌秦香附草归芎，
黄 苍柏量加减，要紧五灵桃没红。
治瘰 鼠疮，满项满胸，破烂流脓，无不应手取效。
砂（二钱，研细） 皂角子（一百个） 干醋（一斤，前二味入醋内浸三日）
入砂锅内熬之，将干，将锅底 砂拌于皂子上，候干，以微火焙干，或以炉台上炕之。
每晚嚼五粒，或八粒，一日早晚或吃两次，以滚水送。然干则皂子过硬，为末服亦可。方内
砂有红白二种，余所用是红色者。未知白色 砂，功效若何。 砂红色者，出库车北山洞
中，夏令从洞中出火，人不能近前，冬令回民赤身近洞取之。《本草》言西域盐卤熬成者，
误也。
Whenever there is pain in the shoulder, arm, waist, or leg, or pain throughout the entire body, it is collectively termed Bi Syndrome (a disease characterized by soreness, numbness, heaviness, and impaired movement of muscles, tendons, and joints). Although it is known that the condition is caused by Wind-Cold invasion, treatment with warm and acrid dispersing herbs fails to cure it. Some argue: "If the pathogen is in the skin and vessels, it is easy to achieve results; if it is in the sinews and bones, it is truly difficult to see effect." This reasoning stems from a failure to consider where pain occurs after Wind-Cold-Damp-Heat pathogens enter the skin. If the pathogen enters the Qi vessels (trachea-like channels), the pain will migrate; if it enters the Blood vessels, the pain will remain fixed in one place. To claim this is due to deficiency is incorrect; deficiency results from prolonged illness, not the other way around. If one merely tonifies Yin, where does the external pathogen go? If one merely expels Wind-Cold and removes Damp-Heat, how can already congealed Blood be revitalized? It is like water encountering Wind-Cold and freezing into ice; once the ice is formed, the Wind-Cold has already dissipated. Understanding this principle, treating Bi Syndrome becomes straightforward. There are many ancient formulas; if they fail, use the following prescription:
Qin Jiao (Radix Gentianae Macrophyllae) - 1 qian
Chuan Xiong (Rhizoma Chuanxiong) - 2 qian
Tao Ren (Semen Persicae) - 3 qian
Hong Hua (Flos Carthami) - 3 qian
Gan Cao (Radix Glycyrrhizae) - 2 qian
Qiang Huo (Rhizoma et Radix Notopterygii) - 1 qian
Mo Yao (Resina Myrrhae) - 2 qian
Dang Gui (Radix Angelicae Sinensis) - 3 qian
Ling Zhi / Wu Ling Zhi (Faeces Trogopterori) - 2 qian, stir-fried
Xiang Fu (Rhizoma Cyperi) - 1 qian
Niu Xi (Radix Achyranthis Bidentatae) - 3 qian
Di Long (Pheretima) - 2 qian, earth removed
If there is slight heat, add Cang Zhu (Rhizoma Atractylodis Lanceae) and Huang Bo (Cortex Phellodendri); if there is deficiency, appropriately add Huang Qi (Radix Astragali) in amounts of 1 to 2 liang.
Formula Song:
Shen Tong Zhu Yu uses Niu Xi and Di Long,
Qiang Huo, Qin Jiao, Xiang Fu, Gan Cao, Dang Gui, and Chuan Xiong,
Huang Qi, Cang Zhu, and Huang Bo are added or subtracted as needed,
The crucial ingredients are Wu Ling Zhi, Tao Ren, Mo Yao, and Hong Hua.
This treats Luo Li (scrofula/lymph node tuberculosis) and Shu Chuang (rat sores/chronic abscesses), characterized by masses filling the neck and chest, which ulcerate and discharge pus. It is effective without exception.
Nao Sha (Sal Ammoniac/Natrii Chloridum Impurum) - 2 qian, finely ground
Zao Jiao Zi (Semen Gleditsiae Sinensis) - 100 pieces
Gan Cu (Dry Vinegar) - 1 jin (500g), soak the first two ingredients in vinegar for three days
Boil in a clay pot until the liquid is nearly dry. Mix the residual Nao Sha powder from the bottom of the pot with the Gleditsia seeds. Allow to dry, then bake over low fire, or dry on a heated kang (brick bed).
Chew 5 or 8 pills every night, taken twice daily (morning and evening) with boiling water. If the Gleditsia seeds are too hard, they may be powdered and taken orally. There are red and white varieties of Nao Sha in the formula; I use the red variety. The efficacy of the white variety is unknown. The red Nao Sha is sourced from caves in the north of Kucha. In summer, fire emanates from the cave, preventing people from approaching; in winter, Hui people enter barefoot to collect it. The Ben Cao Gang Mu states it is made from salt brine in the Western Regions, which is incorrect.
