Point name meaning:

This point is located on the upper limb (i.e., branch) and can be found in the gully-like depression between the sinews of the forearm. Because the triple burner helps to regulate water flow in the body, this depression can be likened to a water ditch. The name of this point therefore reminds the practitioner that just as water ditches are used to irrigate fields, the triple burner channel helps to irrigate the body. The point name also brings to mind TB-6‘s function of moistening the intestines. See acupoint names: origins, meanings, and translations.
