所谓八痞，是由于营卫不和、阴阳隔绝，风邪从外部侵入，与卫气相互搏结，导致血气壅塞不通，从而形成痞证。所谓“痞”，就是阻塞的意思，指腑脏之气痞塞而不能宣通。这通常是由忧愁愤懑导致气机郁积，或者因跌坠造成体内损伤所引起的。其病症表现为腹部容纳气体结聚胀满，时常出现高热。因为名称有八种，所以称为八痞。然而医方书中并未明确显示其具体症状，范汪所收录的华佗《太一决疑双丸方》，声称能治疗八痞、五疝、积聚、伏热、留饮以及往来寒热等症状，但也没有说明“八痞”这一名称的具体含义。
各种痞证，都是由于营卫不和、阴阳隔绝，腑脏痞塞而不能宣通，因此称为痞。只是方书中有八痞、五痞或六痞之分，因为其名称和表现形态不一，所以统称为诸痞。其病症候象，仅仅是腹部气结胀满，闭塞不通，有时伴有高热，这与前述八痞的病情趋势没有太大区别，所以称为诸痞。关于汤药外熨、针刺砭石等治疗方法，另有专门的方剂，补益调养及导引功法，现在附在后面。
《养生方·导引法》中说：端正坐姿，用力伸腰，挺胸仰头，将两手手指相对，向前按压席子使其用力，身体像共头（一种比喻，指头部与胸部向下）一样向下，快要触到席子时再起身，上下往复运动十四次。这种方法可以去除胸肋部的痞塞、脏腑寒冷、疼痛闷胀以及腰脊部的闷痛。
所谓阴阳不和，就会导致三焦隔绝；三焦一旦隔绝，津液运行就不通畅，因此会导致气机阻塞而不调和，这就形成了噎证。这是由于忧愁愤懑引起的，忧愁愤懑则气机结滞，气机结滞就不能宣散流动，从而导致噎塞。所谓“噎”，就是噎塞不通的意思。
所谓五噎，指的是：一是气噎，二是忧噎，三是食噎，四是劳噎，五是思噎。虽然名称有五种，但都是由阴阳不和、三焦隔绝、津液不行，以及忧愁愤懑、发怒等原因产生的，统称为五噎。所谓“噎”，就是噎塞不通的意思。
这种病是由于阴阳不和，脏腑之气不调理，寒气填塞于胸膈之间，导致气机噎塞不通，所以称为气噎。它使人出现喘息心悸、胸背疼痛的症状。
The so-called "Eight Pi" (Pi Syndromes) arises from disharmony between Ying and Wei (Defensive Qi), separation of Yin and Yang, external invasion of Wind pathogenic factors, and their struggle with Wei Qi. This results in stagnation and obstruction of Blood and Qi, leading to the formation of Pi. "Pi" means obstruction, referring to the blockage and failure of the Fu organs to circulate freely. It is caused by emotional distress and resentment leading to Qi accumulation, or internal injury due to falls. The symptoms include abdominal distension due to Qi knotting, accompanied by frequent high fever. Since there are eight types, it is called Eight Pi. However, medical texts do not clearly specify its manifestations. Fan Wang's compilation of Hua Tuo's "Taiyi Jueyi Double Pill Formula" claims to treat Eight Pi, Five Hernias, Accumulations, latent heat, retained fluids, and alternating chills and fever, yet it does not explain the specific name "Eight Pi."
Various Pi syndromes arise from disharmony between Ying and Wei, separation of Yin and Yang, and blockage of the Fu organs preventing free circulation, hence termed Pi. Texts mention Eight Pi, Five Pi, or Six Pi because their names and presentations vary; thus, they are collectively referred to as Various Pis. Their clinical manifestations involve abdominal Qi knotting and distension, obstruction, and occasional high fever, similar in nature to the aforementioned Eight Pi, hence the term Various Pis. Treatments involving decoctions, hot compresses, acupuncture, and moxibustion have separate specific formulas. Tonification, nourishment, and Daoyin (guiding and pulling) exercises are attached below.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) · *Daoyin Fa* (Guiding and Pulling Methods) states: Sit upright, forcefully extend the waist, raise the chest and head, press the palms together facing forward against the mat with force, lower the body as if bowing the head and chest toward the mat, then rise when near the mat. Repeat this up-and-down motion fourteen times. This method removes Pi in the chest and hypochondrium, coldness of the Zang organs, pain and stifling sensation, and heaviness in the waist and spine.
When Yin and Yang are disharmonious, the Sanjiao (Triple Burner) becomes obstructed. When the Sanjiao is obstructed, the distribution of Jin-Ye (Body Fluids) is impaired, causing Qi obstruction and dysfunction, resulting in Ye (Dysphagia/Choking). This is caused by emotional distress and resentment. Distress causes Qi knotting; Qi knotting prevents free flow, leading to Ye. "Ye" refers to obstruction and blockage.
The Five Yehs are defined as: 1. Qi Ye, 2. You Ye (Emotional Ye), 3. Shi Ye (Food Ye), 4. Lao Ye (Fatigue Ye), and 5. Si Ye (Thinking Ye). Although there are five names, all arise from disharmony of Yin and Yang, obstruction of the Sanjiao, impaired movement of Jin-Ye, and emotions such as resentment and anger. They are collectively called Five Yehs. "Ye" refers to obstruction and blockage.
This condition arises from disharmony of Yin and Yang and dysfunction of Zang organ Qi, where Cold pathogenic factors fill the chest and diaphragm, causing Qi obstruction and blockage, hence termed Qi Ye. It manifests as panting, palpitations, and pain in the chest and back.
