GB-23 - Flank Sinews
辄筋 - Zhē jīn
Point Region: Upper abdomen
GB-23, or 'Zhejin' (meaning 'Flank Sinews'), is a local point located on the side of the body. Its name refers to its ability to address issues related to the 'sinews' or 'tendons' of the 'flank' or side of the body.
As a local point, Zhejin is primarily used for issues related to the ribs and chest, such as a stiff chest, a sore throat, and a sense of 'stuckness' in the chest. It is a go-to point for 'clearing heat' and 'regulating' the flow of energy in the chest and ribs. By stimulating this point, you can help to restore a sense of balance and harmony to the entire body.
Zhejin 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 upper body. 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.
