EXT-41 - Outer Ankle Tip
外踝尖 - Wài Huái Jiān
Point Region: Foot/Ankles
EXT-41, or 'Waihuaijian' (meaning 'Outer Ankle Tip'), is a local point located on the ankle. Its name refers to its ability to address issues related to the 'ankle' and 'foot,' as well as a sense of 'stiffness' or 'pain' in the ankle.
As a local point, Waihuaijian is primarily used for issues related to the ankle and foot, such as a stiff ankle, a sore ankle, and a sense of 'weakness' in the lower body. It is a go-to point for 'tonifying' the Kidney and 'strengthening' the body as a whole. By stimulating this point, you can help to restore a sense of balance and harmony to the entire body.
Waihuaijian 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 lower body.
