Capítulo 30 de 81
黄帝内经·灵枢
Overall Paraphrase
Note on textual emendations: In the original text quoted, "膝理/腹理" should be "腠理" (interstices of the skin and muscles), "气盼着" should be "气脱者" (one whose qi has collapsed), "波脱" should be "液脱" (one whose fluids have collapsed), and "脏疾" should be "胫痠" (soreness of the lower legs). The translation below follows the standard edition of Lingshu·Jue Qi.
The Yellow Emperor asked: I have heard that the human body possesses six substances — essence (jing), qi, fluid (jin), liquid (ye), blood, and vessels (mai) — and I originally thought they were all simply "one qi." Now they are divided into six names, and I do not understand the reasoning behind this. Qi Bo explained one by one: Essence is the primordial substance of life that exists before the body takes form, brought into being through the union of the reproductive essences of the two sexes (yin and yang); Qi is disseminated by the Upper Burner (the region above the diaphragm, governing diffusion and effusion), spreading the refined essences of the five grains. Like mist and dew irrigating, it warms the skin, nourishes the entire body, and moistens the hair; Fluid (jin) is the subtle sweat that issues forth when the interstices (cou li, the spaces and gaps of skin and muscle) open; Liquid (ye) is the thick, slippery portion of the refined essences of water and grains, which pours into the bones, making the joints supple and smooth in flexion and extension, seeps outward to moisten and supplement the brain and marrow, and lubricates the skin; Blood is produced when the Middle Burner (the region below the diaphragm and above the navel, governing reception and ripening) receives the refined essences of water and grains, extracts their juices, and transforms them into a red fluid; Vessels (mai) are what constrain the nutritive qi (ying qi, the refined qi that moves within the vessels and nourishes), keeping it within its designated pathways so that it does not leak outward.
The Yellow Emperor asked again: When these six qi have excess or insufficiency, prosperity or decline, abundance or scarcity — how can one observe externally such things as the vacuity or repletion of the brain and marrow, or the clarity or turbidity of the blood and vessels? Qi Bo said: When essence collapses, there is deafness; when qi collapses, the eyes cannot see clearly; when fluid collapses, the interstices open and there is incessant profuse sweating; when liquid collapses, the joints become difficult to flex and extend, the complexion becomes withered and parched, the brain and marrow diminish, the lower legs become sore and weak, and tinnitus rings frequently; when blood collapses, the complexion becomes pale, withered, and without luster, and the pulse passages become empty and vacuous. These are the external manifestations of the collapse and loss of the six qi.
The Yellow Emperor finally asked: Do the six qi have any hierarchy of nobility or baseness, primary or secondary status? Qi Bo said: Each of the six qi has its own domain of command, and there are certain patterns governing their priority, degree, and normalcy. But in the final analysis, the five grains and the stomach are the source from which the six qi are engendered and transformed — like a great sea.
One Qi, Six Names — Same Source, Different Streams
Essence, qi, fluid, liquid, blood, and vessels are not six entirely separate substances, but rather a functional classification of the body's refined materials at different physiological stages and under different states. Essence tends toward the congenital and reproductive; qi tends toward propulsion and warming nourishment; fluid tends to be thin and thin, issuing outward as sweat; liquid tends to be thick and dense, pouring inward into the bones and brain; blood tends toward redness and nourishment; vessels tend toward channeling and restraint. This embodies the Chinese medical concepts of "qi monism" and the holistic view of "essence, qi, blood, and fluids."
What Is Within Must Manifest Without
This chapter discusses deficiency and depletion in terms of "collapse" (tuo), offering the typical external signs of the six collapsing substances: essence collapse with deafness, qi collapse with blurred vision, fluid collapse with profuse sweating, liquid collapse with joint immobility, and blood collapse with pallor and vacuous pulses. This reflects early diagnostic thinking in Chinese medicine — determining internal losses from external orifices, complexion, and pulse — emphasizing the correspondence between internal and external.
The Stomach Is the Great Sea; the Five Grains Are the Source
Although the six qi each have their own domicile and responsibilities, they all depend upon the stomach's receiving, ripening, and transforming of the five grains to engender their refined essences. This provides a classic basis for the concepts that the "spleen and stomach are the acquired foundation" and are the "source of qi and blood production," and it also points to the fact that food and drink constitute the root of continuous supplementation for the vital substances of life.
The six qi represent an ancient functional classification model of the body's basic substances and functions, and they cannot be simplistically equated with modern anatomical tissues. For example, "blood" is fairly close to blood, "vessels" are similar to vascular channels, "fluids" may roughly correspond to tissue fluids, synovial fluid, glandular secretions, and the like, "qi" is closer to energy metabolism and physiological function, and "essence" carries meanings that include hereditary and reproductive substances. These correspondences are only approximate; ancient concepts should not be held to modern microscopic standards or dismissed on that basis.
The "collapse" (tuo) patterns described in the text, such as fluid collapse from profuse sweating (resembling dehydration or sweat loss), blood collapse with pallor and empty pulses (resembling anemia or hypovolemia), and liquid collapse with joint immobility (resembling reduced synovial fluid or malnutrition), possess a certain empirical observational value. However, such correspondences are general and cannot substitute for modern diagnosis.
"The five grains and the stomach as the great sea" aligns with modern nutrition's recognition that diet, through digestion and absorption, provides material and energy for life. Nevertheless, the "stomach" of Chinese medicine is a functional concept and should not be equated with the anatomical stomach.
