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

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.
