Name and classical tradition
Lanwei, 阑尾, is the anatomical name for the appendix: 阑 (闌), the end, what closes; 尾, tail. It is found by palpation, about two cun below ST36, Zusanli, at the most tender spot, and the name tells you what it is used for.
Like EX-LE6, Dannang, it is a 20th-century point with a name taken from Western anatomy: classical medicine did not know the appendix as an organ. It is a good example of how modern acupuncture added points for diseases defined by Western medicine, while locating them, of course, with the traditional method of tenderness to pressure.
