Gao Yun: Bi (Obstruction) refers to the stagnation and涩 (astringent/stagnant) flow of Ying and Wei Qi, leading to impaired circulation. There are Bi syndromes caused by the invasion of Wind, Cold, and Dampness pathogens, as well as those affecting the skin, muscles, vessels, sinews, bones, and their corresponding internal organs. The Six Fu Organs have Shu points, and the Five Zang Organs also have Shu points; the Five Zang Organs have their respective connections, and the Six Fu Organs also have connections. Therefore, there are Bi syndromes of the Five Zang and Six Fu Organs. When Ying and Wei Qi circulate freely, Bi does not occur. As a category of disease, Bi may present with pain, without pain, or with numbness; it may manifest as cold, heat, dryness, or dampness. This chapter comprehensively discusses these manifestations, hence the title "Treatise on Bi" (Bi Lun).
How is Bi generated? (In the *Jia Yi Jing*, the character "Zhi" is interpreted as "Jiang".)
The mixture of Wind, Cold, and Dampness pathogens leads to Bi. Zhang Yun: Bi means obstruction. As stated in the *Yin Yang Bie Lun*: "When one Yin and one Yang knot together, it is called Hou Bi (Throat Obstruction)." In the *Zhi Yao Da Yao Lun*: "Shi Bi (Food Obstruction) causes vomiting." These illustrate the meaning of obstruction. Thus, when Wind, Cold, and Dampness mix and invade, they block the meridians, causing Qi and Blood to stagnate, resulting in Bi syndrome, which includes conditions like gout and numbness. Hua Tuo's *Zhong Zang Jing* states: Bi is caused by Wind, Cold, Summer-heat, and Dampness invading the Zang and Fu organs. Bi means obstruction. When the Five Zang and Six Fu organs are affected by pathogens, disturbing the True Qi, they become blocked and numb, hence called Bi. Zheng Xuan's commentary on the *Yi Tong Gua Yan* states: Bi is a disease caused by the failure of Qi to penetrate. Briefly noted: The term "Bi" in the classic has four meanings. First, as a general term for diseases located in the Yin aspects, seen in the *Shou Yao Gang Rou Pian*. Second, specifically referring to obstruction, such as Shi Bi and Hou Bi. Third, referring to numbness/paralysis, as Wang Bing notes. Fourth, referring to gout and Li Jie (wandering joint pain), such as the Xing Bi, Tong Bi, and Zhuo Bi discussed in this chapter. All these essentially revolve around the concept of obstruction; scholars should study this carefully. The *Yi Qie Jing Yin Yi* cites the *Cang Jie Pian*: Bi refers to numbness of the hands and feet.
Xing Bi (Wandering Bi): Ma Yun: When Wind pathogen predominates, it affects the Yang meridians, resulting in Xing Bi. It feels like insects crawling on the head, face, and limbs. Zhang Yun: Wind is characterized by rapid movement and frequent changes, hence called Xing Bi. Conditions involving wandering pain and joint pain fall under this category. Briefly noted: Zhang follows Lou's *Gang Mu*; the same logic applies to Tong Bi and Zhuo Bi below. The *Zhang Shi Yi Tong* states: Xing Bi is characterized by unpredictable wandering pain, which is the action of Wind. Yue Pi Jia Zhu Fu Tang can be used.
Tong Bi (Painful Bi): Ma Yun: When Cold pathogen predominates, it affects the Yin meridians, resulting in Tong Bi. Cold damages Blood, causing pain at the affected site. Zhang Yun: Yin-Cold pathogen lodging between muscles, sinews, and bones condenses and does not dissipate, preventing Yang Qi from circulating, leading to unbearable pain, i.e., gout. The *Zhang Shi Yi Tong* states: Tong Bi features pain without fixed location, caused by Dampness injuring the Kidney, failing to nourish the Liver, allowing Liver Wind to carry Dampness to the limbs, causing shoulder/back pain, stiffness, and edema. Wutou Tang from the *Jin Gui Yao Lue* can be used; symptoms include body pain as if breaking, and muscle pain like needle pricks or knife cuts. Fuzi Tang from the *Qian Jin Fang* can also be used.
Zhuo Bi (Fixed Bi): Ma Yun: When Dampness pathogen predominates, it affects the skin, muscles, sinews, and vessels, resulting in Zhuo Bi. Dampness is heavy and lingering, and pressing the area does not elicit pain. Zhang Yun: Zhuo Bi is characterized by heavy, fixed limbs, or woody numbness. Dampness transforms according to Earth, so diseases often occur in the muscles. Briefly noted: Chen's *San Yin Fang* states that swelling, fullness, and heaviness indicate excess Dampness. This seems to equate Zhuo Bi with damp-type foot ailment. ○ Zhi Yun: The *Ling Shu* mentions Feng Bi, and the *Shang Han Lun* mentions Shi Bi, indicating Bi caused by a single pathogen. This chapter discusses the mixed invasion of Wind, Cold, and Dampness forming Bi. The *Zhou Bi Pian* states: Wind, Cold, and Dampness lodge between the fen li, compressing fluids into foam. Foam gathers when cold, pushing apart the fen li and causing splitting. Splitting causes pain; pain draws Shen (Spirit/Mind) to the area; Shen generates heat; heat relieves pain; relief leads to Qi reversal; reversal triggers other Bi syndromes. This describes Cold Bi occurring first, followed by recurrence of other Bi. This chapter emphasizes that when Wind predominates, it is Xing Bi; when Dampness predominates, it is Zhuo Bi. This indicates that among the mixed pathogens, the predominant one determines the main pathology. Classics differ because syndromes vary; clinicians must discern accordingly. The *Zhang Shi Yi Tong* states: Zhuo Bi features fixed numbness, hemibody numbness, or numbness of the face, head, arms, or legs. Shen Xiao Huang Qi Tang is suitable.
Bone Bi contracted in Winter: Lou Yun: For diseases caused by Wind, Cold, and Dampness (Xing, Tong, Zhuo Bi), if contracted in Winter, it is Bone Bi; in Spring, Sinew Bi; in Summer, Vessel Bi; in Late Summer, Muscle Bi; in Autumn, Skin Bi. These are named after the season of contraction and the location of the pathogen, not implying separate entities beyond Xing, Tong, Zhuo Bi.
Re-exposure to Wind, Cold, and Dampness: The *Jia Yi Jing* omits the character "Chong" (re-).
Palpitations beneath the heart: Ma Yun: "Gu" (drum/palpitation) ends the sentence; palpitations beneath the heart. Gao Yun: Heart deficiency causes irritability; thus, irritability leads to palpitations beneath the heart. "Gu" means movement. Briefly noted: Wang Bing's interpretation of "fullness" is incorrect.
Upper part pulls as if pregnant: Gao Yun: The *Jing Mai Lun* states: Liver disease causes hernia in men and lower abdominal swelling in women. Thus, upper pulling downward resembles pregnancy.
Sacrum replaces heels, spine replaces head: Gao Yun: Kao is the coccyx. Squatting with the coccyx replaces the heels, indicating Bone痿 (Wei - flaccidity). The upright spine replaces the head, indicating collapse of Tian Zhu (Heavenly Pillar). Briefly noted: Wang Bing interprets this as spasm/cramping, consistent with other commentators. Gao interprets it as flaccidity/weakness, differing in meaning.
Bao Bi (Bladder Bi): Zhang Yun: Bao is the bladder sac. Gao Yun: It is Bladder Bi. Briefly noted: Liu Xi's *Shi Ming* says: Bao implies emptiness, used to hold water. Some say Bladder is named so because it is short and wide. Knowing Bao is the Bladder, Wu Kun's annotation using the female uterus is incorrect.
Internal pain upon pressure, as if scalded with hot water: Briefly noted: The *Bai Bing Shi Sheng Pian* states: Accumulations attaching to the Fu Chong vessel pulse upon touch, and upon releasing hand, heat flows down to both thighs, resembling scalding. This describes muscle heat. Based on this, interpreting internal pain as thigh pain seems correct.
Clear discharge from above: Zhi Yun: The Bladder meridian enters the brain from the vertex; brain seepage produces mucus. Clear discharge upward occurs because Tai Yang Qi is obstructed below and cannot ascend along the meridian. (*Zhang Shi Yi Tong* adds: Bao is the bladder sac. Bladder Qi obstruction blocks water passages, causing internal pain upon pressure, feeling like hot water pouring. Urine gains slight passage due to external heat but remains stagnant. Treatment should warm and assist Qi transformation. The Bladder meridian connects to the brain, hence clear discharge. Since Tai Yang Qi is insecure and Essence leaks upward, warming and tonifying is essential. After essence loss, Cold/Heat invade the Bladder, causing dribbling, penile pain radiating to the anus, and abdominal distension. This is due to fluid exhaustion. Diuretics will cause death. Elderly with Yin deficiency often suffer this. I have seen bladder rupture with uncontrollable dribbling; though temporarily relieved, death follows soon. Refer to a case in the Incontinence section treating Bao Bi with Shen Li Tang modified Sang Piao Xiao San.)
Yin Qi being quiet...: Ma Yun: This explains that internal injury is the root of Bi, allowing external pathogens to invade. Yin Qi is Ying Qi. It is refined and travels with Zong Qi in the meridians. Only when quiet can the Spirits of the Five Zang remain stored. If restless, they perish. Thus, Five Zang Bi requires re-exposure to pathogens. Why do Six Fu Bi occur? Diet nourishes but excess harms. Doubling food intake injures the intestines and stomach. Once injured, pathogens enter via Shu points, causing Bi. The *Sheng Qi Tong Tian Lun* discusses Wei Qi (Yang); this section discusses Ying Qi (Yin). Wang Bing distinguishes Zang/Fu correctly but fails to identify Yin Qi as Ying Qi. Briefly noted: Wu Kun moved these 19 characters to the *Sheng Qi Tong Tian Lun*; uncertain if original. Following Ma Yun for now.
Excessive Qi (Yin Qi): Hua Yun: Wang Bing's note implies internal injury, not external Wind/Cold/Dampness. The *Xuan Ming Wu Qi Pian* says: Pathogens entering Yin cause Bi. Does "pathogen" refer to Yin Qi? Ma Yun: Pathogenic infiltration causes panting. Lung governs Qi; Bi gathering in Lung causes panting. (Same for subsequent text.) Zhi Yun: This clarifies that restless Yin Qi perishes, and Bi gathers in Zang. Yin Qi here means excessive/dissipated Yin Qi that fails to store. Excessive Qi leads to panting, Lung Qi fails to store, and Bi gathers in Lung. Wu Yun: Imbalance of Qi is called Yin Qi. Bi gathering is the condensation of Wind, Cold, and Dampness. Briefly noted: The *Sheng Qi Tong Tian Lun* says: Wind lodges in Yin Qi, Essence perishes, Evil injures Liver. *Shuo Wen*: Yin means infiltrating along channels. Xu Kai says: Infiltrating along channel pathways.
Exhaustion: Ma Yun: Pathogenic infiltration exhausts Yin Blood. Liver governs Blood; Bi gathering in Liver causes exhaustion.
Muscle Severance: Ma Yun: Pathogenic infiltration blocks Muscle Qi. Spleen governs flesh; Bi gathering in Spleen causes severance. Wu Yun: Muscle tearing. Zhi Yun: Scorched/severed muscles, also due to excessive intercourse.
Also Excessive Intercourse: Ma Yun: Some interpret "also benefit interior" as "intercourse," which is plausible. Zhi Yun: "Also" implies not just internal connection of skin/muscle/sinew/bone. Briefly noted: Ma's view is unsettled. (*Yi Tong* reads "Yi" as "Lan" - excessive).
Easy to Cure: Zhang Yun: Wind is Yang pathogen, easily dispersed, hence easy to cure. Cold/Damp Bi are harder to cure as Yin pathogens linger and resist movement.
Diet and Dwelling: Gao Yun: Refers to overeating and improper living conditions, the root of Fu Bi.
Six Fu Organs Also Have Shu Points: Ma Yun: The fen li of Six Fu have Shu points. External Wind/Cold/Dampness strikes these points, internal dietary irregularity responds, pathogens enter via Shu. All 365 points can be Shu. Wang Bing limits Shu to the six Back-Shu points on the Foot Tai Yang, which is incorrect.
Five Zang Have Shu, Six Fu Have He: Zhang Yun: Discusses Zang and Fu mutually. Wang Ang notes: Previous text only lists Chang Bi and Bao Bi. San Jiao has name but no form; Gallbladder attaches to Liver; Stomach is the Sea of Zang/Fu, so no separate Bi discussion.
Manifestations Vary, Treat According to Fault: Ma Yun: Follow the meridian pathways of Zang/Fu to find the affected channel; needle according to the location, whether Shu or He point, and the disease will resolve. Zhi Yun: Select points based on the location of the fault/pathogen. Briefly noted: Zhang considers "manifestation" as Jing-Well points. "Guo" (fault) is read as level tone by Wu, Zhang, Gao following Wang Bing, which is incorrect.
Ying Qi is the Essence-Qi of Grain and Water: Zhang Yun: Ying Qi is Yin Qi, transformed from grain/water essence. *Wei Qi Pian* states: Essence traveling in meridians is Ying Qi. *Zheng Li Lun* states: Food enters stomach, transmits to Lung, nourishing all Zang/Fu. Clear part is Ying, turbid part is Wei. Ying is within vessels, Wei outside. Thus, Ying reaches all Zang/Fu and collaterals.
Wei Qi is the Fierce Qi of Grain and Water: Zhang Yun: Wei Qi is Yang Qi. Yang Qi arrives floating, abundant, and swift, hence "Fierce." Fierce means urgent. *Ben Zang Pian* states: Wei warms fen li, fills skin, plumps cou li, controls opening/closing. *Wei Qi Pian* states: Floating Qi not following meridians is Wei Qi. *Xie Ke Pian* states: Wei Qi sends out its fierce, swift energy, moving ahead in extremities, fen li, and skin without rest. These sections complement each other.
Huang Mo (Diaphragm Membrane): Zhang Yun: Huang refers to spaces between cavities and tissues. *Ci Jin Lun* says: Above Ge Huang lies Parents (Heart/Lung). *Zuo Zhuan* mentions above Gao, below Huang. *Fu Zhong Lun* says: Qi overflows to Large Intestine, attaches to Huang. Source of Huang is below navel. *Jiu Zhen Shi Er Yuan Pian* says: Source of Huang emerges from Bo Yang. *Zhang Lun* says: Sunken into muscle Huang, hitting Qi points. Thus, Huang is not limited to chest/diaphragm. Mo is fascia. Briefly noted: Wang Bing defines empty space; Wu Kun's note on *Fu Zhong Lun* is similar. Zhang misread this note, confusing it with Small Intestine membrane origin in *Ju Tong Lun*. Incorrect. *Bian Que Zhuan* mentions "Nuo Huang"; *Shuo Yuan* writes "Huang Mo", i.e., Huang Mo.
Scattered in Chest and Abdomen: The *Jia Yi Jing* reads "San" (scatter) as "Ju" (gather).
Therefore, No Bi: Zhang Yun: Ying and Wei Qi must not reverse. Reversal causes disease; compliance brings health. Unlike solid organs/tissues, they have no form/traces, so they do not combine with the three pathogens. Formless means no Bi.
Pain Due to Cold: Briefly noted: Wang Bing's note relies on the *Ling Shu Zhou Bi Pian*.
Therefore, No Unblocking (Pain): Commentators follow *Jia Yi Jing*, reading "Tong" (unblock) as "Tong" (pain). We follow this.
Skin Not Nourished: Zhang Yun: *Ni Diao Lun* states: Ying deficiency causes numbness; Wei deficiency causes immobility. "Not nourished" means Qi/Blood do not reach. Ma Yun: Lack of Qi/Blood circulation in skin. Gao agrees. Zhi Yun: Cannot nourish the skin.
Less Yang Qi, More Yin Qi: Zhang Yun: Cold diseases are not always external. If Yang is deficient and Yin excessive, Cold generates internally, exacerbating the condition, resulting in Cold syndrome. Zhi Yun: Cold/Heat depend on human Yin/Yang transformation. Less Yang and more Yin exacerbates internal Cold.
Pathogen Qi Prevails: Zhang Zhaohuang says: "Exacerbating pathogen" means excess Yin increases pathogenic Cold. "Pathogen Qi prevails" means excess Yang increases pathogenic Heat.
Yang Encounters Yin Causes Bi-Heat: Wu Kun: "Zao" (encounter) should be "Cheng" (overcome). Old text "Yang encounters Yin" is inappropriate. Following *Jia Yi Jing*, changing to "Yang overcomes Yin" is more logical. Briefly noted: *Jia Yi Jing* lacks "Bi", which is also plausible. Hua Yun: Or heat below, or dryness question; no answer here.
Two Qi Interact: Zhang Yun: Cold and Dampness. *Mai Yao Jing Wei Lun* states: Excess Yin causes sweating and cold body. Same meaning. Zhang Zhaohuang says: Excess Yang heat causes sweating; moist sweat belongs to Yin/Cold. Clinicians must examine carefully.
No Pain: Wang Ang says: Pain indicates Qi/Blood still circulate. Five Bi involve Qi/Blood deficiency, heavier than pain, hence no pain. Other explanations are unclear.
Meeting Cold Causes "Chong": Ma Yun: "Chong" is "Ji" (urgent/spasm) in *Jia Yi Jing*. Wang Bing's "like insect crawling" is wrong. Wind predominance causes Xing Bi, not triggered by Cold. Zhang Yun: Meeting Cold causes sinew spasm (urgent); meeting Heat causes sinew relaxation (slack). Wu Kun agrees. Briefly noted: Zhi follows Wang Bing. Gao Yun: Cold/Damp clash causes "Chong". Highly erroneous. Chao Yuanfang states: Bi types itch in Heat, hurt in Cold.
