Point Region: Finger/Pinky
EXT-30, or 'Xiaogukong' (meaning 'Small Bone Hollow'), is a local point located on the little finger. Its name refers to its ability to address issues related to the 'little finger' and 'hands,' as well as a sense of 'stiffness' or 'pain' in the hands.
As a local point, Xiaogukong is primarily used for issues related to the hands and fingers, such as a stiff little finger, 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.
Xiaogukong 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.
