痹证，就是疼痛的意思。风、寒、湿三种邪气混杂侵入人体，合在一起形成痹证。其中风气偏胜的叫行痹，特点是疼痛游走不定。寒气偏胜的叫痛痹，特点是筋骨拘挛疼痛。湿气偏胜的叫着痹，特点是肢体浮肿沉重坠胀。既然说是“偏胜”，说明致病因素有侧重。治疗行痹，以疏散风邪为主，辅以散寒祛湿，大致参用补血药剂，所谓治风先治血，血行风自灭。治疗痛痹，以散寒为主，辅以疏风燥湿，大致参用补火助阳药剂，所谓热则气血流通，寒则凝滞闭塞，通则不痛，痛则不通。治疗着痹，以燥湿为主，辅以祛风散寒，大致参用补脾药剂，因为脾土旺盛就能胜湿，且气充足自然没有顽麻感。通用蠲痹汤加减主治，疼痛剧烈的，辅助松枝酒。又有患痹证日久，腿足枯瘦细小，膝盖肿大，名叫鹤膝风。这是三阴经本源亏虚，寒邪侵袭经络，于是形成此症，宜服用虎骨胶丸，外贴普救万全膏，则可以逐渐痊愈。错过这个时机不治疗，就会变成顽固疾病，成为废人。
To treat Kidney deficiency complicated by invasion of Wind, Cold, and Dampness.
Duhuo (Radix Angelicae Pubescentis), Sangjisheng (Ramulus Taxilli), Fangfeng (Radix Saposhnikoviae), Qinjiao (Rhizoma Gentianae Macrophyllae), Weilingxian (Herba Clematidis), Niuxi (Radix Achyranthis Bidentatae) (each 1 qian), Guixin (Cortex Cinnamomi Cassiae, 5 fen), Xixin (Radix Asari), Gancao (Radix Glycyrrhizae Uralensis, roasted, each 3 fen), Danggui (Radix Angelicae Sinensis), Jinmao Gouji (Rhizoma Cibotii Barometz) (each 2 qian). Add two slices of Shengjiang (Rhizoma Zingiberis Recens), decoct in water and take orally.
Danxi stated: For chronic lower back pain, Guan Gui (Cortex Cinnamomi Cassiae) must be used to unblock the meridians for the pain to cease. In cases of severe Cold, Fuzi (Radix Aconiti Lateralis Preparata) should be added. However, if there is Damp-Heat, neither of these two herbs is suitable.
Cangbai Erchen Tang (Two-Crude Two-Chen Decoction) (see Stroke-like syndromes).
To treat internal accumulation of Blood stasis due to sprains, falls, or blows, where turning or shifting causes pain as sharp as a knife or awl piercing.

If urination and defecation are obstructed, add Jiuzheng Dahuang (Radix Rhei Palmati, steamed with wine, 3 qian); in cases of severe trauma with obstruction of urination and defecation, only Dahuang can save the patient. If stool has already passed, then use Guang Sanqi decocted in wine, or Shan Yangxue (Blood of Capra Hircus) mixed with wine, or Qingmuxiang (Radix Aucklandiae) decocted in wine; using any one of these will immediately stop the pain.

Bi Syndrome refers to pain. When Wind, Cold, and Dampness mix and invade together, they form Bi Syndrome. When Wind predominates, it is called Moving Bi (Xing Bi), characterized by wandering pain without fixed location. When Cold predominates, it is called Painful Bi (Tong Bi), characterized by contraction and pain of sinews and bones. When Dampness predominates, it is called Fixed Bi (Zhuo Bi), characterized by edema, heaviness, and drooping sensation. Since it is termed "predominance," the pathogenic factors have specific biases. To treat Moving Bi, dispelling Wind is primary, assisted by eliminating Cold and Dampness; generally, blood-nourishing formulas are incorporated, following the principle that treating Wind requires first treating the Blood; when Blood flows, Wind extinguishes itself. To treat Painful Bi, dispelling Cold is primary, assisted by dispersing Wind and drying Dampness; generally, Fire-warming formulas are incorporated, following the principle that Heat promotes flow while Cold causes stagnation; free flow means no pain, pain means obstruction. To treat Fixed Bi, drying Dampness is primary, assisted by expelling Wind and scattering Cold; generally, Spleen-tonifying formulas are incorporated, because when Earth (Spleen) is robust, it overcomes Dampness, and sufficient Qi eliminates numbness and stiffness. The general treatment uses Juanbi Tang (Eliminate Bi Decoction) with modifications; for severe pain, Songzhi Jiu (Pine Branch Wine) is added as an adjunct. There is also a condition where Bi Syndrome persists for a long time, resulting in withered and thin legs and feet, but swollen knees, named Crane Knee Wind (Hexi Feng). This is due to deficiency of the Three Yin channels, with Cold pathogens invading the collaterals, leading to this syndrome. It is appropriate to take Hugujiao Wan (Tiger Bone Gelatin Pill) and apply Puji Wanquan Gao (Universal Salvation Plaster) externally, so that gradual recovery can occur. If this opportunity is missed and not treated, it becomes a stubborn disease, rendering the person disabled.
