What is the function of DU-11 (shendao) in traditional practices?

DU-11, known as Shendao, is indeed recognized for its role in calming internal wind, which is essential in traditional practices. This point is located on the Du channel, which is significant in regulating the Yang energies and providing stability in the body. Calming internal wind is particularly critical in conditions associated with excess heat, anxiety, or disruptions in the Shen (the mind/spirit), since internal wind can manifest in symptoms such as tremors, dizziness, or even emotional disturbances.

By accessing DU-11, practitioners aim to restore balance and harmony within the body, effectively calming any internal disturbances. This function is particularly valued in treating conditions like epilepsy or other types of convulsive disorders, where the concept of "wind" is often invoked as a pathological factor.

The other choices pertain to different functions related to other organs or energies, which is why they are not linked to DU-11. Tonifying the Kidney, strengthening the Spleen, and clearing heat from the stomach are associated with other acupuncture points and channels that target those specific conditions directly.
