EXT-15 - Flank Hall
胁堂穴 - Xiétáng
Point Region: Armpit
EXT-15, or 'Xietangxue' (meaning 'Flank Hall Point'), is a local point located on the side of the body. Its name refers to its ability to address issues related to the 'flank' or 'side' of the body.
As a local point, Xietangxue is primarily used for issues related to the chest and ribs, 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.
Xietangxue 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.
