Which point serves as a 'Luo Connecting' point?

The 'Luo Connecting' points are specific acupuncture points that facilitate the connection between the primary meridians and their associated Luo vessels. These points play a significant role in the overall balance of qi and blood throughout the body, and they are also involved in addressing conditions related to the specific meridians with which they are associated.

In this case, SP-4 (Gong Sun) is indeed recognized as the Luo Connecting point of the Spleen meridian. Its primary function is to connect the Spleen channel to the Penetrating Vessel (Chong Mai), which helps regulate the flow of qi and blood and thus can influence a variety of digestive and gynecological issues.

This establishes SP-4 as integral not just in treating Spleen disorders but also in impacting the broader system of channels and vessels associated with the Spleen's function. Therefore, it is essential for practitioners to understand the role of this point when considering treatment strategies that involve the Spleen and its related concerns.
