Which points are primarily used for addressing fluid retention?

The use of Ren-9 and SP-9 is well-established in Traditional Chinese Medicine (TCM) for addressing fluid retention.

Ren-9, known as the "Water Division" point, is specifically indicated for regulating phlegm and fluid metabolism. Its location on the Ren channel aids in promoting the movement of fluids throughout the body, helping alleviate conditions associated with excess water retention.

SP-9, or "Yin Ling Quan," is another key point for the treatment of dampness and edema. It is located on the Spleen meridian and plays a central role in transforming and transporting fluids. In TCM, the Spleen is closely linked to the regulation of fluids, and stimulating SP-9 helps to strengthen the Spleen's function, thereby promoting better fluid metabolism and reducing retention.

Together, these points work synergistically to address fluid issues, making them the most appropriate choice in the context of this question.
