GB-12 - Completion Bone
完骨 - Wán gǔ
Point Region: Head
GB-12, or 'Wangu' (meaning 'Completion Bone'), is a local point located on the back of the head. Its name refers to its position on the 'completion bone' or 'mastoid bone,' where it can address issues related to the head and neck.
As a local point, Wangu 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.
Wangu 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.
