徐先生已于卷首分出痿证一门大抵固当分其所因风则阳受之痹感风寒湿之气则阴受之为病多

白虎汤用于治疗热厥证，症状表现为腹部胀满、身体沉重难以翻身、面部污垢、胡言乱语、小便失禁、手足冰冷、自汗出、脉象沉滑。方剂见“暑门”章节。
《内经》说：风、寒、湿三种邪气混杂侵袭人体，合而发为痹证。其中风气偏胜的称为行痹；寒气偏胜的称为痛痹；湿气偏胜的称为着痹。如果在冬季感受邪气，此为骨痹；如果在夏季感受邪气，此为筋痹；如果在夏季感受邪气（注：原文此处可能有误，通常指长夏或特定季节，但依原文直译），此为脉痹；在至阴之时（长夏）感受邪气，此为肌痹；如果在秋季感受邪气，此为皮痹。
《脉经》说：脉象涩而紧，是痹病的表现。
陈无择说：虽然三气共同导致痹证，但其应用有所不同。三气侵袭人的经络，进入筋、脉、皮、肉、肌、骨，如果长久不愈，则会传入五脏。烦闷喘逆而呕吐，这是痹邪客居于肺；心烦、上气、咽喉干燥、担心嗳气、四肢厥冷、腹胀满，这是痹邪客居于心；多饮、小便频数、小腹痛如怀孕状、夜间睡眠则惊悸，这是痹邪客居于肝；容易腹胀、臀部肿胀代替了腰部、脊柱弯曲头部低垂代替了头顶，这是痹邪客居于肾；四肢懈怠无力、发作咳嗽、呕吐泡沫、体内有大寒，这是痹邪客居于脾。又有肠痹、胞痹，以及六腑各有俞穴，风寒湿邪所中，治疗时根据各腑的俞穴施行针灸方法，同时服用驱逐三气、发散邪气的药物，病自然痊愈。
大抵痹证这种疾病，寒气多则为痛痹，风气多则为行痹，湿气多则为着痹。邪气在骨，则身体沉重不能举动；在脉，则血液凝滞不流动；在筋，则屈曲不能伸展；在肉，则麻木不仁；在脾，则畏寒，遇寒则拘急，遇热则松弛。又有血痹，以类相从，外部有支饮也可形成痹证。
谨按：痹证这种病症，有筋脉挛缩不能伸展、肌肉麻木不仁的，与风证极其相似，所以世俗之人多将其归类于风证，通治痿痹证，这是千古以来的弊病。
徐先生已经在卷首分出“痿证”一门，大体上应当区分其病因。风邪则阳经受之，痹证感受风寒湿之气则阴经受之。作为疾病，痹证多重痛、沉着，患者难以去除病根，就像钱仲阳是宋代一代名医，自己患有周痹，只能转移到手足，导致半身偏废，不能完全治愈，可见其难治。况且现在世俗之人多将其归类于风证通治，难怪不能掌握病情。
Baihu Tang (White Tiger Decoction) is used to treat Heat Jue (Heat Reversal Syndrome), with symptoms including abdominal fullness, heaviness of the body making it difficult to turn over, a greasy appearance of the face, delirium, urinary incontinence, coldness of the hands and feet, spontaneous sweating, and a deep and slippery pulse. The formula can be found in the "Summerheat Section".
The Classic says: When Wind, Cold, and Dampness three Qi mix together and invade, they combine to form Bi Syndrome (Obstruction Syndrome). When Wind Qi prevails, it is called Xing Bi (Wandering Bi); when Cold Qi prevails, it is called Tong Bi (Painful Bi); when Dampness Qi prevails, it is called Zhuo Bi (Fixed Bi). If contracted in Winter, this is Gu Bi (Bone Bi); if contracted in Summer, this is Jin Bi (Tendon Bi); if contracted in Summer [Note: Textual variation], this is Mai Bi (Vessel Bi); if contracted at Zhi Yin (Late Summer), this is Ji Bi (Muscle Bi); if contracted in Autumn, this is Pi Bi (Skin Bi).
According to this treatise, the five Zang organ Bi syndromes are recorded in great detail; one should carefully study the original text.
The Pulse Classic says: A choppy and tight pulse indicates Bi Syndrome.
Chen Wuyue said: Although the three Qi jointly cause Bi, their manifestations differ. The three Qi attack the meridians, entering the tendons, vessels, skin, flesh, muscles, and bones. If prolonged without resolution, they enter the five Zang organs. Irritation, fullness, wheezing, and vomiting indicate Bi pathogen lodging in the Lung; vexation, upward rushing of Qi, dry throat, fear of belching, cold limbs, and abdominal distension indicate Bi pathogen lodging in the Heart; excessive thirst, frequent urination, lower abdominal pain resembling pregnancy, and waking with fright during sleep indicate Bi pathogen lodging in the Liver; propensity for distension, swelling of the buttocks replacing the waist, and spinal curvature where the spine replaces the head indicate Bi pathogen lodging in the Kidney; flaccidity of the four limbs, coughing, vomiting of froth, and internal severe Cold indicate Bi pathogen lodging in the Spleen. There are also Chang Bi (Intestine Bi) and Bao Bi (Bladder Bi), and each of the six Fu organs has its Shu points; when attacked by Wind, Cold, and Dampness, treatment involves applying acupuncture and moxibustion according to the respective Fu organ's Shu points, while administering herbs that expel the three Qi and disperse pathogens, leading to natural recovery.
Generally speaking, in Bi syndrome, an excess of Cold results in Tong Bi (Painful Bi), an excess of Wind results in Xing Bi (Wandering Bi), and an excess of Dampness results in Zhuo Bi (Fixed Bi). If in the bones, the body is heavy and immobile; if in the vessels, blood coagulates and does not flow; if in the tendons, flexion occurs but extension is impossible; if in the flesh, there is numbness and insensitivity; if in the Spleen, there is aversion to cold, becoming rigid in cold and relaxed in heat. There is also Blood Bi, which follows similar patterns; externally, Zhi Yin (Branching Fluid Retention) can also manifest as Bi.
Carefully observing: Bi syndrome presents with tendon spasms preventing extension and muscle numbness, which are extremely similar to Wind syndromes. Therefore, laypeople often classify it under Wind syndromes and treat Wei Bi (Flaccidity-Bi) collectively. This is a flaw lasting for millennia.
Mr. Xu already separated the Wei Syndrome (Flaccidity Syndrome) category at the beginning of the volume. Generally, one must distinguish the etiology. Wind pathogen affects the Yang meridians, whereas Bi syndrome caused by Wind-Cold-Dampness affects the Yin meridians. As a disease, Bi is characterized by severe pain and stagnation; patients find it difficult to eradicate. For example, Qian Zhongyang, a renowned physician of the Song Dynasty, suffered from Zhou Bi (General Bi). He could only shift the condition to his hands and feet, resulting in hemiplegia, unable to fully recover. This demonstrates its difficulty to treat. Moreover, since contemporary people often misclassify it as Wind syndrome and treat it uniformly, it is no wonder they fail to grasp the true nature of the illness.
