EXT-1 - Four Alert Spirits
四神聪 - Sì shén cōng
Point Region: Head
EXT-1, or 'Sishencong' (meaning 'Four Spirit Aides'), is a set of four extra points located on the top of the head. Its name refers to its ability to address issues related to the 'spirit' or 'shen,' as well as a sense of mental clarity and focus.
As a local point, Sishencong is primarily used for issues related to the head and neck, such as a headache, dizziness, and a sense of 'stuckness' in the head. It is a go-to point for 'calming' the mind and 'clearing' emotional blockages in the head. By stimulating this point, you can help to restore a sense of peace and tranquility to the mind and body.
Sishencong 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.
