三焦行于诸阳。故置一俞曰原。又曰。三焦者。水谷之道路。原气之别使也。主通行三
气。经历五脏六腑。原者。三焦之尊号。故所至辄为原也。
太渊（肺） 大陵（心包） 太冲（肝） 太白（脾） 太 （肾） 神门（心） 阳池（三焦） 京
骨（膀胱） 丘墟（胆） 冲阳（胃） 合谷（大肠） 腕骨（小肠）
按。难经云。五脏六腑之有病者。皆取其原。王海藏曰。假令补肝经。于本经原穴补一
针。（太冲穴是）如泻肝经。于本经原穴亦泻一针。余仿此。
自太渊至神门皆为俞。自阳池至腕骨为原。海藏皆为十二原者。岂五脏无原。以俞为原
。六腑有原。取原而不取俞耶。
中府（肺之募） 巨阙（心之募） 章门（脾之募） 期门（肝之募） 中脘（胃之募）
按难经云。阳病行阴。故令募在阴。（腹曰阴。募皆在腹。）东垣曰。凡治腹之募。皆为
原气
合。及诸脉之募者。必危。
（俞犹委输之输。言经气由此而输于彼也。）
肺俞（三椎下各开寸半） 心俞（五椎下各开寸半） 肝俞（九椎下各开寸半） 脾俞（十一
椎下各开寸半） 肾俞（十四椎下各开寸半）
按难经云。阴病行阳。（背为阳）故令俞在阳。（人之俞皆在背） 东垣曰。天外风寒之邪
。乘
于外寒。终归外热。以故治风寒之邪。治其各脏之俞。
三焦之气运行于各阳经。因此设立一个腧穴称为“原穴”。又说，三焦是水谷运行的道路，也是原气的别行使者。它主要通行上、中、下三焦之气，流经五脏六腑。“原”是三焦的尊称，所以三焦之气所到达的地方就称为“原穴”。
太渊（肺经） 大陵（心包经） 太冲（肝经） 太白（脾经） 太溪（肾经） 神门（心经） 阳池（三焦经） 京骨（膀胱经） 丘墟（胆经） 冲阳（胃经） 合谷（大肠经） 腕骨（小肠经）
按语：《难经》说，五脏六腑如果有病证，都可以取用它们的原穴。王海藏说，假如要补肝经，就在本经的原穴补一针（即太冲穴）。如果要泻肝经，也在本经的原穴泻一针。其余脏腑仿照此例。
从太渊到神门这些穴位都属于“俞穴”。从阳池到腕骨这些穴位属于“原穴”。王海藏认为十二原穴，难道是因为五脏没有原穴，而以俞穴作为原穴吗？还是因为六腑有原穴，只取原穴而不取俞穴呢？
中府（肺之募穴） 巨阙（心之募穴） 章门（脾之募穴） 期门（肝之募穴） 中脘（胃之募穴）
按语：《难经》说，阳病传行至阴分，所以令募穴位于阴分。（腹部属阴，募穴都在腹部。）李东垣说，凡是治疗腹部的募穴，都与原气相合。以及治疗诸脉的募穴时，病情必定危重。
肺俞（第三椎骨下方两侧各旁开一寸半） 心俞（第五椎骨下方两侧各旁开一寸半） 肝俞（第九椎骨下方两侧各旁开一寸半） 脾俞（第十一椎骨下方两侧各旁开一寸半） 肾俞（第十四椎骨下方两侧各旁开一寸半）
按语：《难经》说，阴病传行至阳分。（背部属阳）所以令俞穴位于阳分。（人的俞穴都在背部。）李东垣说，来自体外的风寒邪气，侵袭于体表寒邪之处，最终归结为外热。因此治疗风寒邪气，应治疗各脏对应的俞穴。
Sanjiao (Triple Burner) Qi circulates through the Yang meridians. Therefore, a specific Shu point is established and called the Yuan-Source point (Yuan-Source point). It is also said that Sanjiao (Triple Burner) is the pathway for water and grain, and it serves as the special envoy of Yuan-Qi (Original Qi). Its primary function is to facilitate the circulation of Qi in the Upper, Middle, and Lower Jiao, passing through the Zang organs and Fu organs. "Yuan" is the honorific title of Sanjiao (Triple Burner); thus, wherever its Qi reaches, it is designated as a Yuan-Source point.
Taiyuan (LU-9, Lung Meridian) Daling (PC-7, Pericardium Meridian) Taichong (LR-3, Liver Meridian) Taibai (SP-3, Spleen Meridian) Taixi (KI-3, Kidney Meridian) Shenmen (HT-7, Heart Meridian) Yangchi (TE-4, Sanjiao Meridian) Jinggu (BL-64, Bladder Meridian) Qiuxu (GB-40, Gallbladder Meridian) Chongyang (ST-42, Stomach Meridian) Hegu (LI-4, Large Intestine Meridian) Wanggu (SI-4, Small Intestine Meridian)
Commentary: The *Nan Jing* (Classic of Difficult Issues) states that when any of the Zang or Fu organs are diseased, their Yuan-Source points may be selected. Wang Haizang stated: For instance, to tonify the Liver Meridian, insert one needle into the Yuan-Source point of this meridian (Taichong, LR-3). To sedate the Liver Meridian, also insert one needle into the Yuan-Source point of this meridian for sedation. Apply this principle to other meridians accordingly.
From Taiyuan to Shenmen, these points belong to the Back-Shu points (Shu points on the back). From Yangchi to Wanggu, these points belong to the Yuan-Source points. Did Wang Haizang consider all twelve Yuan-Source points? Is it because the Zang organs lack Yuan-Source points and use Shu points instead? Or do the Fu organs possess Yuan-Source points, leading practitioners to select Yuan-Source points rather than Shu points?
Zhongfu (LU-1, Front-Mu point of the Lung) Juque (CV-14, Front-Mu point of the Heart) Zhangmen (LR-13, Front-Mu point of the Spleen) Qimen (LR-14, Front-Mu point of the Liver) Zhongwan (CV-12, Front-Mu point of the Stomach)
Commentary: The *Nan Jing* states that Yang diseases transmit to the Yin, hence the Front-Mu points are located in the Yin regions (the abdomen is considered Yin; all Front-Mu points are located on the abdomen). Li Dongyuan stated: Whenever treating the Front-Mu points of the abdomen, they are connected with Yuan-Qi (Original Qi). Regarding the treatment of the Front-Mu points of various vessels, the condition is necessarily critical.
(The term "Shu" is analogous to "Shu" in Weishu (transport), meaning that the channel Qi transmits from here to there.)
Feishu (BL-13, Lung Shu point: below the third thoracic vertebra, 1.5 cun lateral to the midline) Xinshu (BL-15, Heart Shu point: below the fifth thoracic vertebra, 1.5 cun lateral to the midline) Ganshu (BL-18, Liver Shu point: below the ninth thoracic vertebra, 1.5 cun lateral to the midline) Pishu (BL-20, Spleen Shu point: below the eleventh thoracic vertebra, 1.5 cun lateral to the midline) Shenshu (BL-23, Kidney Shu point: below the fourteenth thoracic vertebra, 1.5 cun lateral to the midline)
Commentary: The *Nan Jing* states that Yin diseases transmit to the Yang (the back is Yang); therefore, the Shu points are located in the Yang region (all human Shu points are located on the back). Li Dongyuan stated: External pathogenic factors such as wind-cold invade the exterior cold areas and ultimately manifest as external heat. Consequently, to treat wind-cold pathogens, one should treat the respective Shu points of each Zang organ.
