五脏各有六个腧穴，六腑共有十二个原穴。（《难经》第八十一难指出，五脏都以第三个输穴作为原穴，每脏两个，共十个原穴；另外选取手少阴经的第三个输穴两个，合起来构成十二原穴。六腑则在井、荥、输、经、四穴之后，另设一个原穴，每腑两个，共十二个原穴。这样五脏六腑合计共有二十四个原穴。“原”指的是脐下肾间动气，这是人的生命根本，也是十二经脉的本源，所以称为“原”。三焦运行原气，以经营五脏六腑，因此三焦是原气的别使。因为气行于此处，所以五脏的第一个输穴和第三个输穴被称为原穴；六腑则以第四个穴为原穴。既然原气是三焦的尊称，而三焦运行原气，止于第四个输穴，故名为原。现在说五脏六腑有十二原，意思是五脏六腑各有十二原穴的说法是不对的。综合来说也有二十四个原穴。文中说“六腑有十二原”，是后人妄加的两个字罢了。）
十二原穴出于四肢关节（四关），四关主治五脏疾病。当五脏有病时，通常取用十二原穴。十二原穴是五脏禀受三百六十五节（指全身穴位）中谷气气味所在的地方。（四关指的是四肢。这段文字只提到五脏有十二原穴，是生病的根源所在，并未提及六腑的十二原穴。五脏位于体内，而原穴位于体表，所以五脏的病邪都从外部传入，因此五脏都禀受于十二原穴。这是因为三百六十五个交会穴中的谷气气味都汇聚于此。）
五脏有病时，病气应当反映在十二原穴上，而且每个原穴都有其特定的出处。（原穴的脉气都出自该经的第三个输穴。）清楚地知道原穴的位置，观察其反应，就能了解五脏的病变了。（清楚知道十二原穴所出的位置，又知晓内部对应的五脏，就能精妙地通达五脏所产生的病变。）
属于阳中的少阴的是肺，其原穴出于太渊，左右各一。（日夕时分属少阴，所以称为阳中之少阴。）
属于阳中的太阳的是心，其原穴出于大陵，左右各二。（日中时分属太阳，所以称为阳中之太阳。）
属于阳中的少阳的是肝，其原穴出于太冲，左右各二。（日出初阳时分属少阳，所以称为阳中之少阳。）
属于阴中的太阴的是肾，其原穴出于太溪，左右各二。（夜半时分重阴，所以称为太阴。）
属于阴中的至阴的是脾，其原穴出于太白，左右各二。（位居上部，为四脏之阴的极致，所以称为至阴。）
膈的原穴出于鸠尾，只有一个。（膈气位于鸠尾之下，所以鸠尾为原穴。）
肓的原穴出于脖胦，只有一个。（肓指的是下肓，位于脐下一寸五分处，脖胦即指此处。）
凡是这十二个原穴，主治五脏六腑的疾病。出现胀满症状时取用三阳经的原穴，出现完谷不化的泄泻症状时取用三阴经的原穴。（胀满取六腑所属的三阳经原穴；泄泻取五脏所属的三阴经原穴。）
如今，五脏有病，好比身上扎了刺。（外邪侵入身体，就像扎了刺一样。）
好比出汗不畅。（五志藏神，如同汗液郁结一样。）
好比打结。（阴阳积聚，如同绳结一样。）
好比闭塞。（气血不通，如同闭塞一样。）
刺虽然扎得久，仍然可以拔出来；汗虽然郁积得久，仍然可以消散；结虽然打得久，仍然可以解开；闭塞虽然持续得久，仍然可以疏通。有人说久病不可治疗，这种说法是不对的。善于使用针刺的人，治疗疾病就像拔刺、散汗、解结、通闭一样。即使疾病时间很久，仍然可以治愈。说不能治愈的，是因为没有掌握正确的治疗方法。（三阳经不通就像闭塞一样。说没有掌握方法，是指高明的医生治疗都能痊愈。）
针刺热证时，要像手伸进热水里那样迅速。（针刺热证时要决泻热气，不久留针，慢慢出针使病气快速排出，所以比喻为手探热水，形容动作迅速。）
针刺寒证时，要像人不想行走那样缓慢。（针刺寒证时要长时间留针，使温气聚集以补虚，所以比喻为人行走迟缓，好像不想走一样，等待气至。）
如果阴分有阳分的热疾，取用足三里穴。前往针刺不要懈怠，待气至下行后才停止；如果气未下行，则重新开始施针。（各种肠道疾病被视为阴阳失调引起的疾病。）
病症表现为头部高位且病位在内者，取用阴陵泉穴；病症表现为头部高位且病位在外者，取用阳陵泉穴。（病位在头部称为“高”。病根在脾经足太阴内侧的，所以取足太阴经的第三个输穴阴陵泉。病位在头部称为“高”，病根在胆经足少阳外侧的，所以取足少阳经的第三个输穴阳陵泉。）
The five Zang organs each have six Shu points, and the six Fu organs have twelve Yuan source points. (According to Chapter 81 of the Nan Jing [Classic of Difficult Issues], the five Zang organs all use the third Shu point as the Yuan point, two per organ, totaling ten Yuan points; additionally, the third Shu points of the Hand Shaoyin meridian are selected, two in total, forming the twelve Yuan points. For the six Fu organs, after the Jing-Well, Ying-Spring, Shu-Stream, and Jing-River points, a separate Yuan point is established, two per organ, totaling twelve Yuan points. Thus, combining the five Zang and six Fu organs, there are twenty-four Yuan points in total. "Yuan" refers to the Qi movement between the kidneys below the umbilicus, which is the root of human life and the foundation of the twelve meridians, hence named "Yuan". The San Jiao [Triple Burner] circulates Yuan Qi to manage the five Zang and six Fu organs; therefore, the San Jiao is the special envoy of Yuan Qi. Since Qi flows here, the first and third Shu points of the five Zang organs are named Yuan points; for the six Fu organs, the fourth point serves as the Yuan point. Since Yuan Qi is the honorific title of the San Jiao, and the San Jiao circulates Yuan Qi stopping at the fourth Shu point, it is named Yuan. Now, stating that the five Zang and six Fu organs have twelve Yuan points implies that each has twelve Yuan points, which is incorrect. In summary, there are twenty-four Yuan points. The statement "the six Fu organs have twelve Yuan points" in the text is an erroneous addition by later generations.)
The twelve Yuan source points originate from the four Guan [junctions of limbs], and the four Guan govern diseases of the five Zang organs. When the five Zang organs are diseased, one should typically select the twelve Yuan source points. The twelve Yuan source points are where the five Zang organs receive the Qi and flavor from the three hundred and sixty-five joints [acupoints]. (The four Guan refer to the four limbs. This passage only mentions that the five Zang organs have twelve Yuan points, which are the origin of disease, and does not mention the twelve Yuan points of the six Fu organs. The five Zang organs are internal, while the Yuan points are external; thus, pathogenic factors affecting the five Zang organs enter from the exterior, so the five Zang organs all derive from the twelve Yuan points. This is because the Qi and flavor from the grain [nutritive Qi] in the three hundred and sixty-five intersecting acupoints converge here.)
When the five Zang organs are diseased, the pathological Qi should manifest at the twelve Yuan source points, and each Yuan point has its specific origin. (The pulse Qi of the Yuan points all originates from the third Shu point of their respective meridians.) By clearly knowing the location of the Yuan points and observing their responses, one can understand the harm caused to the five Zang organs. (By clearly knowing where the twelve Yuan points originate and understanding their internal correspondence with the five Zang organs, one can profoundly comprehend the diseases generated by the five Zang organs.)
The Shaoyin [Lesser Yin] within Yang is the Lung; its Yuan point originates from Taiyuan (LU-9), bilateral. (Sunset belongs to Shaoyin, hence called Shaoyin within Yang.)
The Taiyang [Greater Yang] within Yang is the Heart; its Yuan point originates from Daling (PC-7), bilateral. (Noon belongs to Taiyang, hence called Taiyang within Yang.)
The Shaoyang [Lesser Yang] within Yang is the Liver; its Yuan point originates from Taichong (LR-3), bilateral. (Early sunrise belongs to Shaoyang, hence called Shaoyang within Yang.)
The Taiyin [Greater Yin] within Yin is the Kidney; its Yuan point originates from Taixi (KI-3), bilateral. (Midnight involves heavy Yin, hence called Taiyin.)
The Zhiyin [Ultimate Yin] within Yin is the Spleen; its Yuan point originates from Taibai (SP-3), bilateral. (Positioned superiorly, representing the extreme of Yin among the four Zang organs, hence called Zhiyin.)
The Yuan point of the Diaphragm originates from Jiutui (CV-15), unilateral. (The Qi of the diaphragm resides below Jiutui, so Jiutui is the Yuan point.)
The Yuan point of the Huang [Bladder/Meninges] originates from Boyang (CV-17/CV-12 context dependent, here referring to the area near umbilicus), unilateral. (Huang refers to the lower Huang, located 1.5 cun below the umbilicus; Boyang refers to this area.)
All these twelve Yuan source points govern diseases of the five Zang and six Fu organs. For distension, select the Yuan points of the Three Yang meridians; for undigested food diarrhea, select the Yuan points of the Three Yin meridians. (Distension takes the Yuan points of the Six Fu organs belonging to the Three Yang meridians; diarrhea takes the Yuan points of the Five Zang organs belonging to the Three Yin meridians.)
Now, disease in the five Zang organs is like having a thorn stuck in the body. (Pathogenic invaders entering the body are like a thorn.)
It is like sweat being trapped. (The five emotions store the Spirit, akin to trapped sweat.)
It is like a knot tied. (Accumulation of Yin and Yang is like a knot.)
It is like obstruction. (Stagnation of Blood and Qi is like obstruction.)
Although a thorn has been stuck for a long time, it can still be pulled out; although sweat has been trapped for a long time, it can still be dispersed; although a knot has been tied for a long time, it can still be untied; although obstruction has persisted for a long time, it can still be resolved. Some say that chronic diseases cannot be treated; this view is incorrect. A skilled practitioner treats diseases as if pulling out thorns, dispersing sweat, untying knots, and resolving obstructions. Even if the disease has lasted a long time, it can still be cured. Those who say it cannot be cured have simply not mastered the correct technique. (Obstruction of the Three Yang meridians is like blockage. Saying one has not mastered the technique means that expert physicians can cure all such conditions.)
When treating heat syndromes with acupuncture, act swiftly, like dipping a hand into hot water. (To treat heat, drain the heat Qi quickly without retaining the needle for long; withdraw slowly to allow pathogenic Qi to exit rapidly, hence compared to dipping a hand into hot water, indicating speed.)
When treating cold syndromes, act slowly, like a person unwilling to walk. (To treat cold, retain the needle for a long time to gather warm Qi for tonification, hence compared to walking slowly or standing still, waiting for Qi arrival.)
If there is a Yang-type heat disease in the Yin aspect, select Zusanli (ST-36). Proceed without negligence; stop only when the Qi descends; if the Qi does not descend, restart the manipulation. (Various intestinal diseases are considered disorders of Yin and Yang.)
For diseases presenting high up in the head and located internally, select Yinlingquan (SP-9); for diseases presenting high up in the head and located externally, select Yanglingquan (GB-34). (Disease located in the head is termed "high". If the root is in the Spleen meridian, Foot Taiyin, on the inner side, select the third Shu point of Foot Taiyin, Yinlingquan. If the disease is high in the head and the root is in the Gallbladder meridian, Foot Shaoyang, on the outer side, select the third Shu point of Foot Shaoyang, Yanglingquan.)
