EXT-29 - Great Bone Hollow
大骨空 - Dà Gǔ Kōng
Point Region: Finger/Thumb
EXT-29, or 'Dagukong' (meaning 'Great Bone Hollow'), is a local point located on the thumb. Its name refers to its ability to address issues related to the 'thumb' and 'hands,' as well as a sense of 'stiffness' or 'pain' in the hands.
As a local point, Dagukong is primarily used for issues related to the hands and fingers, such as a stiff thumb, a sore hand, and a sense of 'weakness' in the hands. It is a go-to point for 'clearing heat' and 'regulating' the flow of energy in the hands and fingers. By stimulating this point, you can help to restore a sense of balance and harmony to the entire body.
Dagukong 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 hands and fingers. It's a reminder of the power of local points to provide targeted relief and restore a sense of comfort and vitality to the entire body.
