Which three Luo channels pass through LI 15?

The three Luo channels that pass through LI 15 are the Small Intestine (SI), Large Intestine (LI), and San Jiao (SJ) channels.

LI 15, located on the shoulder, serves as an important point of intersection for these channels. Each of these channels relates to specific physiological and energetic functions within the body. The San Jiao channel, connected with the governing of the body's water metabolism and the distribution of qi, aligns with the location of LI 15, highlighting its role in the shoulder region. The Large Intestine channel connects to the lower gastrointestinal system which is vital for overall digestion and elimination, also relevant to the shoulder’s function and associated musculature. The Small Intestine channel, which is important for digestion and nutrient absorption, complements the functions of the LI and SJ channels.

These interconnections at LI 15 demonstrate the integrative aspect of the Luo channels in balancing energies and supporting bodily functions, particularly in this shoulder region. This understanding of channel pathways is essential for practitioners in traditional Chinese medicine as it informs treatment strategies and point selection.
