Large Intestine Meridian

LI-2, or 'Erjian' (meaning 'Second Space'), is the 'Ying-Spring' and 'Water' point of the Large Intestine channel. It's located in the 'second' space between the index finger's joint and the knuckle, giving it its name.

As a 'Ying-Spring' point, LI-2 is known for its ability to clear heat along the channel. Think of it as a small stream that can wash away impurities. It is particularly effective for 'damp-heat' conditions, such as those that cause sore throats, toothaches, or inflammation. It's often used when the body is trying to release pent-up heat and toxins.

This point represents the second stage of the Large Intestine channel's journey, where the initial energy from LI-1 begins to move more deeply into the body. Erjian's role is to ensure this flow is smooth and unobstructed, helping to maintain a cool, balanced internal environment.
