GB-32 - Middle Ditch
中渎 - Zhōng dú
Point Region: Leg
GB-32, or 'Zhongdu' (meaning 'Middle Ditch'), is a local point located on the side of the thigh. Its name refers to its position as a 'middle ditch' or 'valley' that can be used to address issues related to the thigh and leg.
As a local point, Zhongdu is primarily used for issues related to the thigh and leg, such as a stiff thigh, a sore knee, 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.
Zhongdu 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.
