The Urinary Bladder Channel of Foot, Greater Yang

The Kidneys (Yin) and the Urinary Bladder (Yang) are paired Organs. They correspond to Water in the Five Phases, the winter season, the cold climactic condition, the northerly direction, the color black, the emotion of fear, the taste of salt, a rotten smell, and the sound of groaning. Their sensory organ is the ear. Their opening is the urethra. They control the bones, marrow, and brain, and their health is reflected in the hair of the head.

The main function of the Urinary Bladder is to transform fluids into urine and excrete it from the body.

In Qigong, the Urinary Bladder has never enjoyed serious attention. However, its pairing partner the Kidney is one of the most important organs—one with which all Qigong practitioners are concerned and train most often. The reason for this is simply that the Kidneys are the residence of the Original Essence.
