LU9 is a highly significant point, serving as the Yuan-source, Shu-Stream (Earth), and Hui-Meeting point of the Vessels. It is the primary point for tonifying Lung Qi and Lung Yin, making it indispensable for chronic cough, asthma, and shortness of breath due to deficiency. Its influence on the vessels makes it crucial for circulatory issues, such as poor circulation or cold extremities. A classic pairing is with SP6 to further nourish Yin and blood, especially in chronic deficiency conditions.
