HT-6 - Yin Cleft
阴郄 - Yīn xì
Point Region: Wrist
HT-6, or 'Yinxi' (meaning 'Yin Cleft'), is the 'Xi-Cleft' point of the Heart channel. Its name refers to its position in a 'cleft' or 'crevice' where 'Yin' energy can be accessed and regulated.
As a 'Xi-Cleft' point, Yinxi is a go-to point for managing acute pain and 'deficiency heat' in the Heart channel. It is particularly effective for night sweats, hot flashes, and other symptoms of 'Yin deficiency.' It can also be used to address 'anxiety' and 'hysteria,' as it helps to 'calm the spirit' and restore a sense of inner peace.
Yinxi acts as a vital access point to the heart and the mind, providing a direct and effective way to address blockages and restore a sense of balance and harmony. It's a reminder of the power of local points to provide targeted relief and restore a sense of comfort and vitality to the upper body.
