黄帝曰。愿闻其奇邪而不在经者。岐伯曰。血络是也。黄帝曰。刺血络而仆者。何也。血出而射者。何也。血少黑
而浊者。何也。血出清而半为汁者。何也。发针而肿者。何也。血出若多若少而面色苍苍者。何也。发针而面色不变而
烦者。何也。多出血而不动摇者。何也。愿闻其故。岐伯曰。脉气盛而血虚者。刺之则脱气。脱气则仆。血气俱盛。
而阴气多者。其血滑。刺之则射。阳气蓄积。久留而不泻者。其血黑以浊。故不能射。新饮而液渗于络。而未合和于血
也。故血出而汁别焉。其不新饮者。身中有水。久则为肿。阴气积于阳。其气因于络。故刺之血未出而气先行。故肿。
阴阳之气。其新相得。而未和合。因而泻之。则阴阳俱脱。表里相离。故脱色而苍苍然。刺之血出多色不变而烦 者。
刺络而虚经虚经之属于阴者。阴脱故烦 。阴阳相得。而合为痹者。此为内溢于经。外注于络。（言阴阳不虚实相倾而病
痹痛者此其血多而内外俱壅也）如是者。阴阳俱有余。虽多出血。而弗能虚也。黄帝曰。相之奈何。岐伯曰。血脉者盛。
坚横以赤。上下无常处。小者如针。大者如筋。则而泻之。万全也。故无失数矣。失数而反。（反即胀论所谓必更其道也）
各如其度。黄帝曰。针入而肉着者。何也。岐伯曰。热气因于针。则针热。热则肉着于针。故坚焉。
布局与五癃津液别同。而词旨修洁过之。末段叙不动摇。独用另笔。可悟行文断续之妙。
黄帝说：我想听听那些奇异邪气而不在于经脉中的情况。岐伯说：那就是血络（浅表静脉）。黄帝说：为什么针刺血络后会导致人昏倒？为什么有的出血呈喷射状？为什么有的血色少、黑且浑浊？为什么有的血出清稀且一半是汁液？为什么出针后局部会肿胀？为什么有的出血量或多或少但面色发青苍暗？为什么出针后面色没有改变却感到心烦？为什么有的大量出血后身体却不摇动？我想听您讲讲其中的缘故。
岐伯说：脉气盛而血虚的人，针刺后会耗脱正气，正气耗脱就会昏倒。气血都旺盛，且阴气偏多的人，其血液滑利，针刺时血液就会喷射而出。阳气蓄积，长久停留而不宣泄，血液就会黑而浑浊，所以不能喷射。刚喝完水，水液渗入络脉，尚未与血液调和，所以血出而汁液分离。如果不是刚喝水，而是体内有水湿停滞，时间久了就会导致肿胀。阴气积聚在阳分，阻滞于络脉，所以针刺时血还未出来，气先运行，导致肿胀。阴阳之气刚刚相合但未调和，此时如果泻之，会导致阴阳俱脱，表里分离，所以面色脱失而显得青苍。针刺出血多但面色不变却心烦的，是因为刺络导致经脉空虚，属于阴分的经脉空虚，阴气耗脱所以心烦。阴阳之气相合，结合成为痹证，这是气血内溢于经脉，外注于络脉。（意思是阴阳不虚不实相互倾轧而病发痹痛，这种情况血多且内外都壅滞）。像这种情况，阴阳都有余，即使大量出血，也不能使其虚弱。
黄帝说：如何辨识呢？岐伯说：血脉充盛，坚硬横斜且颜色发红，位置上下不固定，小的如针尖，大的如筋脉，就依此进行泻法，就能万无一失。所以不要违背这个原则。违背了原则就会相反（“反”即《胀论》所说的必须改变其道），各自符合其病理程度。
黄帝说：为什么针入后肌肉附着在针上呢？岐伯说：热气依附于针，使针变热，热则肌肉附着在针上，所以感觉坚紧。
这段文字布局与《五癃津液别》篇相同，但文辞旨意更加精炼高洁。末尾叙述“不动摇”的情况，单独使用另外的笔法，可以领悟文章行文断续的妙处。
Huangdi said: I wish to hear about the strange pathogens that are not located in the meridians. Qibo said: These are the blood collaterals (superficial veins). Huangdi said: Why does one faint after puncturing the blood collaterals? Why does the blood spray out? Why is the blood scanty, dark, and turbid? Why is the blood clear with half of it being fluid? Why does swelling occur after withdrawing the needle? Why does the complexion turn pale and bluish despite varying amounts of bleeding? Why does one feel vexed without a change in complexion after withdrawing the needle? Why does one remain steady without trembling despite significant blood loss? I wish to hear the reasons for these phenomena.
Qibo said: In cases where meridian qi is abundant but blood is deficient, puncturing will deplete the qi. Depletion of qi leads to fainting. When both blood and qi are abundant, and yin qi is predominant, the blood is slippery; thus, puncturing causes it to spray. When yang qi accumulates and remains stagnant for a long time without being released, the blood becomes black and turbid, hence it cannot spray. If water has just been drunk, the fluids seep into the collaterals before harmonizing with the blood; therefore, the blood comes out while the fluid separates. If water was not recently drunk, but there is water retention in the body, prolonged stagnation leads to swelling. When yin qi accumulates in the yang aspect and obstructs the collaterals, upon puncturing, the qi moves forward before the blood emerges, causing swelling. When yin and yang qi have newly combined but are not yet harmonized, applying draining methods will cause both yin and yang to collapse, separating the interior from the exterior; thus, the complexion loses its luster and appears bluish. In cases where significant blood is lost, the complexion remains unchanged, yet vexation occurs, it is because puncturing the collaterals empties the meridians. Emptiness in the meridians belonging to yin leads to depletion of yin, causing vexation. When yin and yang qi combine to form Bi syndrome (obstruction syndrome), this indicates that blood overflows internally into the meridians and externally into the collaterals. (This means that when yin and yang are neither deficient nor excess but clash against each other, causing Bi pain, there is excessive blood and obstruction both internally and externally). In such cases, both yin and yang are in excess; even with significant blood loss, they cannot be rendered deficient.
Huangdi said: How can one identify them? Qibo said: When the blood vessels are full, hard, transverse, red, and vary in location from upper to lower, small as needle points or large as sinews, one should apply draining methods accordingly to ensure complete safety. Therefore, do not deviate from these principles. Deviating will lead to opposite results (as mentioned in the Chapter on Distension, one must change the approach), each conforming to their pathological extent.
Huangdi said: Why does the flesh adhere to the needle after insertion? Qibo said: Heat attaches to the needle, making the needle hot. Heat causes the flesh to adhere to the needle, resulting in a sensation of tightness.
The structure of this passage is similar to that of the "Treatise on Five Obstructions and Differentiation of Body Fluids," but its language and intent are more refined. The final section describes the phenomenon of "no trembling" using a separate narrative style, illustrating the subtlety of the text's interrupted flow.
