Ling Shu: On Abscesses and Carbuncles (Chapter 81)

Holistic Paraphrase

The original text of this chapter has suffered from textual errors and omissions in its transmission. The following is a coherent paraphrase based on context and standard collations such as the Tai Su.

The Yellow Emperor asked: I have heard that after the stomach and intestines receive water and grain, the Upper Burner outputs Defensive Qi (the yang qi that warms the body surface), which warms the flesh between the skin and muscles, nourishes the bones and joints, and penetrates the striae of the skin; the Middle Burner outputs dew-like subtle essences, which flow upward into the furrows of the flesh, seep into the minute collaterals (the finest vessels), where fluids and humors harmonize and transform into red blood. When blood is harmonized, the minute collaterals are first to fill, then spill into the net-like collaterals. When these are full, the blood then enters the primary channels. When both yin and yang channels are replete with qi and blood, they move in concert with breathing, with order and regularity, circulating endlessly in accord with heaven and earth. In treatment, one takes the pulse to regulate qi, and applies reinforcement or drainage according to deficiency or excess: improper drainage leads to insufficiency of righteous qi; needling too quickly causes qi to wane easily; the duration of needle retention must follow proper sequence; improper reinforcement leads to excess of qi and blood. When qi and blood are harmonized, the physical form and qi remain stable. I already understand the principles of blood and qi being in or out of balance, but I still wish to understand where abscesses and carbuncles arise from, and how to determine their outcome—success or failure, and the nearness or distance of death or survival. How is this judged?

Qi Bo said: The channels move without cease, conforming to the celestial degrees and corresponding to earthly patterns. Therefore, if the heavenly mansions lose their degrees, the sun and moon will experience eclipses; if the earthly veins lose their order, waterways will overflow, grass and trees will not grow, the five grains will not flourish, roads will become impassable, the common people cannot come and go, and settlements become separated and isolated. So it is with qi and blood. Allow me to explain the reasons.

Blood vessels, Nutritive Qi, and Defensive Qi circulate without rest, corresponding above to the starry mansions and below to the number of the channels. When cold evil invades the channels and collaterals, blood circulation becomes congealed and sluggish; when blood is stagnant and blocked, Defensive Qi gathers at the affected site and cannot return normally, thus forming abscesses and swellings. When cold evil stagnates for a long time, it transforms into heat; when heat prevails, it rots the flesh; when flesh rots, it becomes pus. If pus is not drained, it decays the sinews; when sinews decay, it injures the bones; when bones are injured, the marrow is depleted; if it cannot be discharged through the bone cavities, the blood becomes exhausted and vacuous, the sinews, bones, and flesh lose nourishment, the channels and vessels are destroyed and leak, and the toxic heat fumigates the five viscera. When the five viscera are injured, death results.

Discussion of Specific Abscesses and Carbuncles

• Occurring at the throat: Called Ferocious Carbuncle (Meng Ju). If not treated promptly, it will transform into pus; if the pus is not discharged and blocks the throat, death occurs within half a day. If it has already formed pus, the ancients held that one could drain the pus, then hold swine lard in the mouth and eat cold foods; recovery follows in three days.
• Occurring at the neck: Called Heavenly Carbuncle (Yao Ju). The sore is large with a red-black color. If not urgently treated, the heat descends into the Yuan Ye region, injures the Conception Vessel in front, and inwardly fumigates the liver and lungs. Death occurs in about ten or more days.
• Occurring at the nape of the neck: Called Brain Melting (Nao Shuo). The complexion shows no joy, and the neck pains as if pierced by needles. If vexation and restlessness appear, death is certain and untreatable.
• Occurring at the shoulder and arm: Called Purplish Carbuncle (Ci Ju). If red-black in color, treat urgently; one may cause sweating to reach the feet, and the five viscera will not be injured.
• Occurring at the axilla: Red and hard in appearance, it is called Rice Carbuncle (Mi Ju). The ancients used a slender long acupuncture stone to prick it superficially, then applied swine lard ointment. Recovery occurs in six days; do not wrap it. If the carbuncle is hard and does not rupture, it is called Horsetail Fistula with Clustered Glands (Ma Dao Jia Ying), and requires urgent treatment.
• Occurring at the chest: Called Well Carbuncle (Jing Ju). Its shape resembles a soybean. If it rises for three to four days and is not treated early, it will descend into the abdomen. Untreated, death occurs in seven days.
• Occurring at the chest and breast area: Called Sweet Carbuncle (Gan Ju). Green in color, shaped like grain kernels or a trichosanthes fruit, often accompanied by alternate chills and fever. It should be treated urgently to eliminate the chills and fever; the text here reads "death in ten years, with pus emerging after death," which is suspect and likely a textual error.
• Occurring at the flank: Called Defeated Carbuncle (Bai Zhi). This condition is mostly seen in women and may be treated with moxibustion. If it has already become a large abscess with pus, there may grow within it small fleshy growths the size of red beans. The ancients recorded boiling the roots of certain herbs in water for internal use, and having the patient wear thick clothing and sit over a pot to induce sweating reaching the feet.
• Occurring at the buttocks: Called Sharp Carbuncle (Rui Ju). Red, hard, and large; urgent treatment is required. If untreated, death occurs in thirty days.
• Occurring at the inner thigh: Called Crimson Spreading (Chi Shi). If not urgently treated, death occurs in sixty days. If both inner thighs are simultaneously affected, and left untreated, death occurs within ten days.
• Occurring at the knee: Called Purplish Carbuncle (Ci Ju). The swelling is large and painful, the skin color remains unchanged, accompanied by chills and fever, hard as stone. Do not cut it open with an acupuncture stone—misuse will cause death. One must wait until it softens before incising with a knife or stone; only then can the patient survive.
• Occurring at a joint with internal and external correspondence: This is untreatable. If it occurs on the yang aspect, death occurs in a hundred days; if on the yin aspect, death occurs in thirty days.
• Occurring at the lower leg: Called Rabbit Gnaw (Tu Nie). The red color penetrates deeply to the bone. Treat urgently; if untreated, it will injure the person.
• Occurring at the inner ankle: Called Walking Slow (Zou Huan). Its appearance resembles an abscess, but the skin color does not change. Puncture its Shu points multiple times to stop the chills and fever; the prognosis may be survival without death.
• Occurring at the top and bottom of the foot: Called Four Excesses (Si Yin). A large carbuncle; treat urgently. If untreated, death occurs in a hundred days.
• Occurring at the side of the foot: Called Vicious Carbuncle (Li Ju). Initially it is not large, about the size of a little finger. Treat urgently to remove the black necrotic tissue; if it does not clear and instead enlarges, and is left untreated, death occurs in a hundred days.
• Occurring at the toes: Called Detaching Carbuncle (Tuo Ju). If the color is red-black, the prognosis is poor; if not red-black, the prognosis is better. If the condition does not lessen, the ancients believed that the affected toe should be urgently amputated; otherwise, death will ensue.

Differentiation Between Abscess (Yong) and Carbuncle (Ju)

The Yellow Emperor asked: How do abscesses and carbuncles differ?

Qi Bo said: When Nutritive and Defensive Qi stagnate and remain within the channels, the blood congeals and does not move; when blood does not move, Defensive Qi is consequently obstructed and cannot pass through. Stagnation and inhibition prevent movement, thus generating heat. When great heat does not stop, the heat prevails and rots the flesh; rotting flesh becomes pus. However, an abscess does not penetrate deeply: the bone marrow will not wither and dry, and the five viscera will not be injured. Thus it is called an Abscess (Yong).

The Yellow Emperor asked: What is a carbuncle?

Qi Bo said: When heat qi is blazing and fierce, it penetrates deeply into the skin and flesh, drying up the sinews and marrow, internally connecting with the five viscera, and exhausting qi and blood. The sinews, bones, and healthy flesh beneath the carbuncle are all destroyed; therefore it is called a Carbuncle (Ju). The characteristic of a carbuncle is darkened, hard skin resembling the hide of an ox's neck. The characteristic of an abscess is thin, glossy skin. These are their appearances.

🧠 Deep Understanding

Core Principles 💡

The core medical rationale of this chapter is built upon the holistic view of "qi and blood circulate freely, internally and externally correspond":

1. Disruption of Qi and Blood Circulation Is the Origin of Abscesses and Carbuncles
   The qi and blood of the channels circulate without ceasing, corresponding to heaven and earth. Once cold evil attacks the channels and collaterals, blood congeals and becomes blocked; defensive qi stagnates at the site, and local swelling forms. This aligns with the Nei Jing saying, "When Nutritive Qi does not follow, and counterflows within the flesh striae, abscesses and swellings are born."

2. Transformation of Cold into Heat and Heat Prevailing to Rot Flesh
   First there is congelation from cold, then stagnation transforms into heat; when heat prevails, the flesh rots and becomes pus. This pathological chain of "cold → stasis → heat → putrefaction → pus" constitutes the basic model by which traditional Chinese surgery understands infectious swellings.

3. Abscesses Are Superficial, Carbuncles Are Deep, with Different Prognoses
   Abscesses are superficial, not injuring the bone marrow or five viscera; carbuncles are deeply penetrating, injuring the sinews and marrow, connecting to the five viscera, and exhausting qi and blood—with a dangerous prognosis. Thin, glossy skin indicates an abscess; dark, hard skin like an ox's neck indicates a carbuncle. This became a key point of differentiation for later generations.

4. Emphasis on Location and Early Intervention
   The text enumerates sites from the throat, neck, chest and flanks, joints, to the toes, stressing "urgent treatment" and "death if untreated," demonstrating that the ancients already recognized the close relationship between anatomical location and the degree of infectious danger.

Modern Perspective 🌟

• Rough Pathological Correlations
  "Cold evil invading the collaterals → blood congelation and blockage → defensive qi gathering → transformation into heat, rotting flesh, and forming pus" bears certain similarity to the processes of local circulatory disturbance, congestion, exudation, suppuration, and necrosis seen in modern inflammatory responses. Deep infections, osteomyelitis, necrotizing fasciitis, and gangrene also resemble the descriptions of deep-penetrating "carbuncles" injuring bones and viscera.

• Early Value of the Classification System
  This chapter is one of the few surgical monographs in the Huang Di Nei Jing. Its assessment of prognosis by location, depth, skin color, chills and fever, and hardness reflects the systematic observational capacity of ancient empirical medicine.

• Historical Limitations Demand Objective Evaluation
  Many judgments such as "death in X days," "untreatable," and "cannot be treated" were empirical summaries of the natural course of severe infections under ancient medical conditions and cannot be directly applied to modern practice. The records of acupuncture stones, moxibustion, toe amputation, and herbal decoctions are ancient external treatment principles, meant only for scholarly study and not constituting any modern diagnostic or therapeutic recommendation.

Wellness Insights ⚡

• Guard righteous qi; avoid prolonged cold evil: Keep warm, avoid prolonged cold-damp environments, and dry off sweat promptly after exercise.
• Qi and blood value free flow: Moderate activity and avoiding prolonged sitting or lying help qi and blood circulate and reduce local stagnation.
• Clean and properly treat minor skin wounds: Do not squeeze red, swollen lumps yourself, especially on the face, joints, and feet.
• Moderation in emotions and diet: Maintain regular bowel movements and adequate sleep to support overall harmony of qi and blood.
• Seek medical attention promptly for redness, swelling, heat, pain, or persistent fever: Do not imitate any ancient external treatments from classical texts on your own.
