LU-7 is classified as which type of point?

LU-7, also known as Lieque, is classified as a confluent point because it is an important point on the Lung meridian that connects to the Ren (Conception Vessel) meridian. Confluent points serve as gateways or access points to the eight extraordinary vessels, which play a significant role in balancing and integrating the body's energy.

LU-7 is known for its functions related to respiratory issues, influencing conditions like cough and asthma, and it can also affect the heart and overall Qi circulation due to its connection to the Ren vessel. This classification reflects its role in treating various conditions that are beyond the simple effects of local needling along the Lung meridian.

The other classifications do not apply to LU-7. Connecting points relate more to linking channels or meridians, Major Lou points focus on the specific entry of Qi into the luo-connecting vessels, and Eight extraordinary points are distinct from confluent points as they pertain to the extraordinary vessels themselves, not the direct connections to the primary meridians.
