GV-28 - Gum Intersection
龈交 - Yín jiāo
Point Region: Mouth (gum)
GV-28, or 'Yin Jiao' (meaning 'Gum Intersection'), is the terminal point of the Governing Vessel. It is a local point located on the gum, where it can address issues related to the mouth and face.
As the terminal point, Yin Jiao is a go-to point for a wide range of conditions, from a sore throat and a dry mouth to a stiff neck and headache. It is a vital point for 'clearing heat' and 'regulating' the flow of energy in the entire body. By stimulating this point, you can help to restore a sense of balance and harmony to the entire body.
Yin Jiao acts as a vital access point to the core of the body, providing a direct and effective way to address blockages and restore a sense of comfort and vitality to the lower body.
