Which point is indicated for moistening the internal organs to relieve nocturnal enuresis?

Ren-4, also known as "Guanyuan," is often utilized for its function in nourishing and moistening the internal organs, particularly when addressing issues related to the kidneys and reproductive system. This point is located on the midline of the lower abdomen and is traditionally associated with the regulation of the lower jiao (the lower region of the body including the kidneys and bladder) and is critical in treatments for conditions such as nocturnal enuresis.

When targeting nocturnal enuresis, the focus is on strengthening the kidneys and enhancing their ability to hold urine. Ren-4 plays a significant role in tonifying kidney qi and consolidating its function, thus alleviating symptoms of frequent urination during the night. This aligns with its traditional use in TCM to bolster the essence and fluids of the body, making it a suitable choice for this specific condition.

In comparison, while other points listed may have their own functions — such as K-7’s role in fluid metabolism or SP-6’s broader action on the reproductive and digestive systems — they do not directly target the simultaneous collection and strengthening of the kidney's yin and qi to the same degree as Ren-4 does in the context of treating nocturnal enuresis.
