What category does LI-3 belong to?

LI-3, also known as Hegu, is classified as a Shu Stream point. The Shu Stream points are typically located at the proximal aspect of the metacarpals or metatarsals and serve multiple functions, including tonification and moving of Qi. These points are often important in treating disorders related to the respective organ and can influence the flow of Qi and blood, impacting conditions such as pain or stagnation.

Additionally, Shu Stream points are associated with the Wood element in traditional Chinese medicine, but they primarily function in the context of their classification as transport points. Knowing that LI-3 is specifically a Shu Stream point helps practitioners identify its role in various treatment strategies, such as dispelling wind and alleviating pain in the arm and hand regions.

The other classifications such as Wood, Earth, and Fire may pertain to different acupuncture points across the meridian systems but do not apply to LI-3 directly, emphasizing its unique classification and importance in acupuncture practice.
