痹因外邪，病本在经，而深则连脏，故其在上则有喘呕，有吐食；在中则为胀满，为疼
痛；在下则为飧泄，为秘结诸病，此皆风痹之兼证也。凡见此者，当于各门权其缓急先后而
随证治之。
一、痹证之风胜者，治当从散，宜败毒散、乌药顺气散之类主之。若以风胜而兼微火者
，宜大秦艽汤，或九味羌活汤之类主之。
一、痹证之寒胜者，但察其表里俱无热证，即当从温治之，宜五积散，或小续命汤、甘
草附子汤之类主之。若寒甚气虚者，宜《三因》附子汤之类主之。
一、痹证之湿胜者，其体必重，或多寒，或多痰，或多汗，皆脾弱阴寒证也。若羌活胜
湿汤，乃兼风散湿之剂也。五积散，乃温经散湿之剂也。真武汤，乃温中除湿之剂也。《三
因》附子汤，乃补脾燥湿之剂也。调气平胃散，乃行气行湿之剂也。五苓散，乃利水导湿之
剂也。二陈汤，六君子汤，乃化痰去湿之剂也。大抵治湿者欲其燥，欲燥者宜从暖。盖脾土
喜燥而恶湿，喜暖而恶寒，故温脾即所以治湿也。然又有湿热之为病者，必见内热之证，滑
数之脉，方可治以清凉，宜二妙散及加味二妙丸、当归拈痛汤之类主之。其有热甚者，如抽
薪饮之类亦可暂用，先清其火而后调其气血。
一、风痹之证，大抵因虚者多，因寒者多。惟血气不充，故风寒得以入之，惟阴邪留滞
，故经脉为之不利，此痛痹之大端也。惟三气饮及大防风汤之类，方能奏效，凡治痹之法，
惟此为最。其有宜酒者，即以三气饮浸酒服之亦妙，法见本方，或用易老天麻丸亦可。
痹证由外邪引起，病位根本在经脉，若深入则牵连脏腑。因此，病在上部会出现气喘、呕吐或吐食；病在中部会出现胀满、疼痛；病在下部会出现完谷不化的泄泻、便秘等各种病症，这些都是风痹的兼夹证候。凡是见到这些症状的，应当根据各门（分类）权衡病情的缓急先后，随证进行治疗。
一、痹证中风气偏胜的，治疗应当以疏散为主，适宜使用败毒散、乌药顺气散之类的方剂主治。如果因风气偏胜而兼有轻微火邪的，适宜使用大秦艽汤，或九味羌活汤之类的方剂主治。
一、痹证中寒气偏胜的，只要观察其表里都没有热证，就应当以温法治疗，适宜使用五积散，或小续命汤、甘草附子汤之类的方剂主治。如果寒邪很盛且气虚的，适宜使用《三因方》中的附子汤之类的方剂主治。
一、痹证中湿气偏胜的，患者身体必然沉重，或伴有怕冷，或多痰，或多汗，这些都是脾虚阴寒的证候。其中，羌活胜湿汤，是兼具祛风散湿作用的方剂；五积散，是温通经络、散除寒湿的方剂；真武汤，是温中焦、除湿气的方剂；《三因方》附子汤，是补益脾气、燥湿的方剂；调气平胃散，是行气化湿的方剂；五苓散，是利水渗湿导邪外出的方剂；二陈汤、六君子汤，是化痰去湿的方剂。大抵治疗湿邪的方法在于使其干燥，想要干燥适宜从温暖入手。因为脾土喜欢干燥而厌恶潮湿，喜欢温暖而厌恶寒冷，所以温补脾脏就是治疗湿邪的方法。然而又有湿热致病的情况，必须见到内热的症状，脉象滑数，才可以采用清凉之法治疗，适宜使用二妙散及加味二妙丸、当归拈痛汤之类的方剂主治。其中热势严重的，如抽薪饮之类的方剂也可以暂时使用，先清除火热，然后调理气血。
一、风痹这类病症，大多是因为正气虚弱所致，也多与寒邪有关。只有血气不充盈，风寒之邪才得以侵入；只有阴邪留滞体内，经脉才会因此不利，这是痛痹的主要机理。只有三气饮及大防风汤之类的方剂，才能奏效，凡是治疗痹证的方法，以此为最佳。其中有适宜用酒治疗的，可以将三气饮浸泡在酒中服用也很奇妙，方法见本方记载，或者使用易老天麻丸也可以。
Bi syndrome is caused by external pathogenic factors, with the disease root located in the meridians; if it penetrates deeply, it involves the zang-fu organs. Therefore, when located in the upper body, it presents with panting and vomiting, or regurgitation of food; when located in the middle, it manifests as distension and fullness, and pain; when located in the lower body, it results in undigested diarrhea (Sun Xie), constipation, and other diseases. These are all concurrent syndromes of Wind-Bi. For any such manifestations, one should weigh the urgency and sequence according to respective categories and treat based on the specific syndrome.
1. In Bi syndrome where Wind predominates, treatment should focus on dispersing. It is appropriate to use formulas such as Baidu San (Resolving Toxicity Powder) or Wuyao Shunqi San (Aucklandia Decoction for Regulating Qi). If Wind predominance is accompanied by slight Heat/Fire, Da Qin Jiao Tang (Great Notopterygia Decoction) or Jiu Wei Qiang Huo Tang (Nine-Ingredient Notopterygia Decoction) may be used.
2. In Bi syndrome where Cold predominates, provided there are no Heat signs in both the exterior and interior, treatment should employ warmth. Appropriate formulas include Wu Ji San (Five Accumulations Powder), Xiao Xuming Tang (Minor Chengming Decoction), or Gancao Fuzi Tang (Licorice and Aconite Decoction). If Cold is severe and Qi is deficient, Fuzi Tang (Aconite Decoction) from *San Yin Fang* (Treatise on Causative Factors of Diseases) is suitable.
3. In Bi syndrome where Dampness predominates, the patient’s body will necessarily feel heavy, often accompanied by aversion to cold, excessive phlegm, or profuse sweating. These are all syndromes of Spleen deficiency with Yin-Cold. Among them, Qianghuo Shengshi Tang (Notopterygia Decoction for Overcoming Dampness) is a formula that disperses Wind and eliminates Dampness; Wu Ji San (Five Accumulations Powder) warms the meridians and dissipates Dampness; Zhenwu Tang (True Warrior Decoction) warms the middle and removes Dampness; Fuzi Tang from *San Yin Fang* tonifies the Spleen and dries Dampness; Tiaoqi Pingwei San (Regulating Qi and Harmonizing Stomach Powder) promotes Qi movement and resolves Dampness; Wuling San (Five-Ling Powder) promotes urination to guide out Dampness; Erchen Tang (Two-Aged Powder) and Liujunzi Tang (Six-Gentlemen Decoction) resolve Phlegm and eliminate Dampness. Generally, treating Dampness requires drying; to dry, one should employ warmth. This is because the Earth element of the Spleen prefers dryness and dislikes dampness, prefers warmth and dislikes cold. Thus, warming the Spleen is equivalent to treating Dampness. However, there are cases of Damp-Heat pathology. Only when internal Heat signs and a slippery-rapid pulse are present can cooling methods be applied, using formulas such as Ermiao San (Two-Marvels Powder), Jiami Ermiao Wan (Modified Two-Marvels Pill), or Danggui Niangtong Tang (Angelica Decoction for Relieving Pain). For severe heat, Chuxin Yin (Drawing Out Fire Decoction) may be temporarily used to first clear the Fire before regulating Qi and Blood.
4. Wind-Bi syndromes are mostly due to deficiency and often involve Cold. Because Qi and Blood are not sufficient, Wind and Cold pathogens can invade; because Yin pathogens remain stagnant, the meridians become obstructed. This constitutes the main mechanism of Pain-Bi. Only formulas such as Sanqi Yin (Three-Qi Infusion) and Dafengfang Tang (Great Wind-Preventing Decoction) can achieve efficacy. Among all methods for treating Bi, this is considered the best. For those suitable for wine therapy, soaking Sanqi Yin in wine for administration is also excellent (see method in the original formula description); alternatively, Yilao Tianma Wan (Old Yi’s Gastrodia Pill) may be used.
