Which of the following does NOT describe the function of DU-15?

DU-15, also known as Yaoyangguan, is an important acupuncture point located on the governor vessel. Its functions are primarily associated with addressing issues related to the head, neck, and spine, as well as certain neurological conditions.

The functions of DU-15 include eliminating wind, particularly when considering conditions that may be associated with internal or external pathogenic factors, such as wind-heat or wind-cold. Additionally, DU-15 benefits the neck and spine by promoting circulation and reducing tension in the region, which makes it valuable for treating conditions like cervical stiffness or pain.

DU-15 is also recognized for its ability to address muteness, especially when this condition is linked to issues affecting the yang or the spirit, reflecting its role in facilitating communication and expression.

The function that does not align with DU-15's therapeutic effects is the enhancement of appetite. Although appetite can be influenced by various factors in traditional Chinese medicine, it is not a function attributed to this particular point. The benefit of appetite is often associated with points that have a direct connection to the spleen and stomach, which regulate digestion and the desire for food.
