Name and classical tradition

Geshu, 膈俞, is the transport point of the diaphragm. 膈 is the diaphragm; 俞, the transport point. The point lies at the level of the seventh thoracic vertebra, between BL15, the Shu of the Heart, above, and BL18, that of the Liver, below, and the diaphragm separates precisely those regions. The Lingshu (Spiritual Pivot), in the chapter Bei Shu (背腧), includes it in its list: “膈腧在七焦之間”, the Shu of the diaphragm is in the space of the seventh vertebra.

Geshu is also the meeting point of the Blood (血會) among the eight Influential (Hui) points. The Nanjing (Classic of Difficulties) states it in Difficulty 45, “血會膈俞”, and Yang Jizhou's Zhenjiu Dacheng (Great Compendium of Acupuncture and Moxibustion), from the Ming period, reasons it from the position of the point: above is the Shu of the Heart, which governs the Blood, and below that of the Liver, which stores it; between the two, Geshu is the meeting point of the Blood.

The reference works record a graphic variant of its name, 鐲俞, not independently verified. Next to it, on the outer line, is BL46, Geguan.

Named functional sets from the school: here the point does not act on its own, but through the role it plays within the maneuver.

  • Tonify the BloodPregnancyCovers the three sources of Blood: it is produced in the Center (LR13, Influential point of the organs), gathered at BL17 (Influential point of Blood) and SP10, rooted in the Kidney (BL52, home of the Zhi, and CV4), and driven from LU9, the Influential point of the vessels. SP6 stitches the whole together.
