What is the distance of Ren4 from the navel and its corresponding organ?

The acupoint Ren4, also known as "Guanyuan," is located 3 cun inferior to the umbilicus (navel). This point is clinically significant because it is associated with the reproductive organs and is also a key point for nourishing the Yin and strengthening the Kidneys.

The connection to the organ corresponds to the overall implications of Ren4 in relation to reproductive health and the kidneys, making it relevant for conditions affecting the Kidney and reproductive functions. In Traditional Chinese Medicine (TCM), the kidneys are viewed as foundational to overall vitality and reproductive health.

Understanding the measurements in cun is essential for accurately locating acupuncture points. The cun measurement system is based on the patient's body, where one cun is roughly equivalent to the width of the patient's thumb. At the level of Ren4, the anatomical landmarks used for its identification align well with this system.

Other options do not correspond accurately to the location or the organ association relevant to Ren4, which further solidifies that the correct choice emphasizes both its distance from the navel and its importance in TCM practice.
