Which point is the shu-stream point (yuan source) on the spleen meridian?

The correct identification of the shu-stream point and yuan source point on the spleen meridian is pivotal for understanding acupuncture point applications and their therapeutic significance. In this case, the spleen's shu-stream point and yuan source point is located at SP 3.

SP 3, known as "Taibai," serves a vital role in the spleen's functions, primarily focusing on transforming and transporting nutrients, as well as managing dampness. This point is particularly important for conditions related to digestion and spleen qi deficiency. The uniqueness of this point stems from its dual role as both a shu-stream point, which is typically used to treat conditions of the internal organs, and a yuan source point, which strengthens the organ's primary qi and manifests through its physical and emotional attributes.

In contrast, the other points mentioned do not serve this dual function for the spleen. Understanding the specific roles of each point enables practitioners to make informed decisions during treatment, enhancing the overall effectiveness of acupuncture therapy.
