Name and classical tradition
Sanjiaoshu, 三焦俞, is the Back-Shu point of the Triple Energizer. 三焦, the three burners or three fires, is the formless Fu organ that Chinese medicine entrusts with the circulation of fluids and Qi through the three regions of the trunk; 俞 is the transport point. The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) places it one and a half cun to each side of the thirteenth vertebra, that is, the first lumbar.
No further historical data or ancient alternative names are known; the name 三焦背俞穴 that is sometimes found is descriptive and modern. Beside it, on the outer line, is BL51, Huangmen.
