The Kidney Meridian

The Kidney Meridian (also known as the Foot Shaoyin Kidney Meridian, 足少阴肾经) is one of the 12 primary meridians in Traditional Chinese Medicine (TCM). It is a Yin meridian and is closely paired with the Bladder Meridian, which is its corresponding Yang meridian.

In TCM, the Kidneys are considered the foundation of life, storing the Essence (Jing) and governing growth, reproduction, and longevity.
