What is the main attribute of LI-18?

The main attribute of LI-18, also known as "Futu," is that it is classified as a Window of the Sky point. This classification is particularly significant because Window of the Sky points are believed to help connect the body with the mind and spirit, facilitating the flow of Qi between these aspects of a person. LI-18 is located on the neck and has important functions related to the throat, voice, and communication, which aligns with the concept of clarity and expression inherent in Window of the Sky points.

These points are often used in clinical practice to treat conditions that involve disturbances either physically in the neck area or psychologically, such as emotional distress that may be expressed or felt in the throat. This makes the designation of LI-18 as a Window of the Sky point an essential aspect of its therapeutic significance.

In contrast, Ying Spring points, Xi Cleft points, and Luo Connecting points each have their distinct attributes and therapeutic uses, focusing on different physiological and pathological functions within traditional Chinese medicine. Thus, while LI-18's classification as a Window of the Sky point stands out for its unique applications, the other classifications refer to other types of energetics and treatment pathways in acupuncture.
