Select the category that both DU-14 and DU-15 points belong to.

DU-14 and DU-15 are classified as Sea of Qi points. These points are significant in Traditional Chinese Medicine (TCM) as they are associated with the gathering and control of Qi within the body's meridian system.

The Sea of Qi points are located along the Du meridian, which runs along the spine and is responsible for energy distribution. DU-14, situated at the nape of the neck, is particularly influential as it regulates Qi, influences the Yang aspects of the body, and is often utilized in treatments for fever, immune system support, and respiratory issues. DU-15, located just below DU-14, serves as a support point for the brain and also contributes to the overall Yang balance in the body.

Understanding the role of these points enriches clinical practice, as practitioners can effectively apply them in various treatment protocols based on their unique properties. Other categories, such as Sea of Yang, Window of Sky, and Ghost Points, refer to different sets of points with distinct functions and therapeutic implications, which do not encompass both DU-14 and DU-15.
