痹证是由风、寒、湿三种邪气共同侵袭人体而形成的。其症状表现为肌肉麻木不仁或疼痛，这是由于人体正气虚弱，腠理（皮肤纹理及汗孔）开泄，导致风邪乘虚而入。
这种邪气首先侵犯经络，随后深入五脏。如果在春季感受痹邪，称为筋痹（以关节屈伸不利为主的痹证），筋痹久治不愈又再次感受邪气，就会传入肝脏形成肝痹。肝痹的症状是夜间睡眠时容易惊醒，饮食增多但小便频数。如果在夏季感受痹邪，称为脉痹（血脉运行不畅的痹证），会导致血脉凝滞不通，使人面色萎黄。脉痹久治不愈又再次感受邪气，就会传入心脏形成心痹。心痹的症状是心下悸动如鼓，气突然上逆导致喘息，咽喉干燥，喜欢打嗝。在长夏（夏季最后十八天）感受痹邪，称为肌痹（肌肉病变的痹证），肌痹久治不愈又再次感受邪气，就会传入脾脏形成脾痹。脾痹的症状是四肢懈怠无力，咳嗽呕吐。如果在秋季感受痹邪，称为皮痹（皮肤感觉障碍的痹证），表现为皮肤完全失去知觉。皮痹久治不愈就会传入肺脏形成肺痹。肺痹的症状是气喘急促且伴有疼痛。如果在冬季感受痹邪，称为骨痹（骨骼沉重疼痛的痹证），表现为骨骼沉重无法抬起，行动不便且疼痛。骨痹久治不愈又再次感受邪气，就会传入肾脏形成肾痹。肾痹的症状是腹部胀满。诊察这类患者的脉象，如果脉大且涩，属于痹证；脉来急促，属于痹证；脉涩且紧，也属于痹证。（引自《医说》同卷内容）
医经中有“偏风”的候证，又有“半身不遂”的候证，还有“风偏枯”的候证。这三者大体相同，但古人分别设立篇目论述：指病因属风邪的称为偏风，指疾病表现为半身不能活动的称为半身不遂，指一侧肌肉萎缩变小的称为偏枯。这些病症都是由脾胃虚弱所致。脾胃是水谷之海，水谷的精微物质化为气血，以滋润濡养身体。如今脾胃虚弱，则水谷精微的滋养有所不足，导致气血偏虚，被邪气所中，因此出现半身不遂，甚至发展到肌肉枯萎变小。治疗方法应当兼顾调理脾胃（引自《鸡峰普济方》）。
“风淫末疾”是指四肢的疾病。凡是中风，病邪都归于手足，因为四肢为诸阳之本。疾病的程度有轻重之分，所以病情较轻者，俗称“小中”。一位老医生常论述说，“小中”不需要进行深度治疗，只需服用温和平和的汤剂，扶助正气以驱逐湿痹，使毒邪流向一边，其余痛苦不再发作，患者随顺性情调养生活。虽然不能完全恢复如初，但还可以勉强维持岁月。如果强力攻伐病邪，即使暂时平复，患者往往恬不知耻地不加戒备，一旦疾病复发，就难以支撑了。这就像捕捉寇贼，将其拘禁在一间屋子里，不让他逃逸自生他念；或者驱逐他出去，他再次回来时，祸患必然比之前更严重。这番话很有道理。但我看到世上的病人大多如此，只是常人之情，将虚幻的身体视为己有，哪有得了病成为废人而不极力治疗的？这种情况很难用笔墨言语来比喻（引自《泊宅编》）。
Bi syndrome (Obstruction Syndrome) is formed by the combined invasion of Wind, Cold, and Dampness pathogens. Its manifestations include numbness or pain in the muscles. This occurs because the body's healthy Qi is deficient, causing the Couli (pores and skin texture) to open, allowing Wind pathogen to enter.
The pathogen first affects the Meridians and Collaterals, then enters the Zang organs. If Bi syndrome is contracted in Spring, it is called Jin Bi (Sinew Bi), characterized by stiffness of tendons and joints. If Jin Bi persists and is re-infected by pathogens, it transmits to the Liver, forming Gan Bi (Liver Bi). The symptoms of Gan Bi include waking up with fright during sleep, increased food intake but frequent urination. If contracted in Summer, it is called Mai Bi (Vessel Bi), where blood vessels do not flow smoothly, leading to sallow complexion. If Mai Bi persists and is re-infected, it transmits to the Heart, forming Xin Bi (Heart Bi). Symptoms of Xin Bi include palpitations like a drum beating under the heart, sudden upward reversal of Qi causing asthma, dry throat, and a tendency to belch. If contracted in Late Summer, it is called Ji Bi (Muscle Bi). If Ji Bi persists and is re-infected, it transmits to the Spleen, forming Pi Bi (Spleen Bi). Symptoms of Pi Bi include flaccidity and weakness of the four limbs, coughing, and vomiting. If contracted in Autumn, it is called Pi Bi (Skin Bi), characterized by total loss of sensation in the skin. If Skin Bi persists, it transmits to the Lung, forming Fei Bi (Lung Bi). Symptoms of Fei Bi include rapid breathing, asthma, and pain. If contracted in Winter, it is called Gu Bi (Bone Bi), characterized by heavy bones that cannot be lifted, immobility, and pain. If Gu Bi persists and is re-infected, it transmits to the Kidney, forming Shen Bi (Kidney Bi). Symptoms of Shen Bi include abdominal distension. Pulse diagnosis for these conditions: a large and choppy pulse indicates Bi; a rapid pulse indicates Bi; a choppy and tight pulse also indicates Bi (Same source as above).
Medical classics mention the presentation of Pian Feng (Hemiplegic Wind), Ban Shen Bu Sui (Hemiplegia), and Feng Pian Ku (Wind-induced Wasting). These three are essentially similar, but ancient texts separated them into different chapters: referring to the etiology as Wind implies Pian Feng; referring to the disease manifestation as inability to move half the body implies Ban Shen Bu Sui; referring to the wasting of muscles on one side implies Pian Ku. All are caused by deficiency and weakness of the Spleen and Stomach. The Spleen and Stomach are the sea of water and grain; the essence of food and drink transforms into Blood and Qi to nourish the body. Now, due to Spleen and Stomach deficiency, the nourishment from food essence is insufficient, leading to partial deficiency of Blood and Qi, which allows pathogens to strike. Thus, hemiplegia occurs, potentially progressing to muscle wasting. The treatment method should address both the primary condition and regulate the Spleen and Stomach (All from Jifeng Fang).
"Wind Yin Mo Ji" refers to diseases of the extremities. In all cases of Zhong Feng (Wind Strike/Stroke), the pathogen returns to the hands and feet. The severity of the disease varies. Therefore, mild cases are commonly known as Xiao Zhong (Minor Stroke). An old physician often argued that Xiao Zhong does not require aggressive deep treatment. One should only take mild and balanced decoctions to support Healthy Qi, expel Damp-Bi, and divert toxins to one side, so that other suffering ceases. The patient should follow their nature and rest. Although full recovery may not be achieved, life can still be prolonged. If one attacks the pathogen forcefully, even if there is temporary remission, the patient often becomes complacent and unguarded. If the disease recurs, it will be difficult to manage. It is like capturing a bandit: confining him in a room prevents him from escaping and plotting elsewhere; driving him out means he will return, and the disaster will be worse than before. This statement is very reasonable. However, I see that most patients in the world are like this. Ordinary people, attached to their illusory bodies, rarely refrain from vigorous treatment when disabled by illness. This is difficult to explain merely with words and writing (From Bo Zhai Bian).
