“The Kidneys are a source of water, blood, and other bodily fluids. They are the fire element and the “original Qi”. In Traditional Chinese Medicine, the kidneys are said to help with reproductive health as well as with regulating the body’s circulations of its natural fluids.”

“According to ancient Chinese medicine the kidney and bladder meridian are responsible
for balancing and storing one’s qi as well as the total flow of energy in a person’s body. It is
believed that the kidneys store the essence or “Jing.” Jing is a concentrated source of qi that
resides in one’s body and allows you to be energetic and creative. The less Jing you possess the
more you might experience a feeling of stress or anxiety as well as a lack of motivation.”

“The kidneys are the seat of courage and willpower, and therefore any impairment in the kidney meridian results in feelings of fear and paranoia.”

…kidneys and water character in Chinese. The color is deliberate to represent the element of water, and the kidneys connect by a down flow of water in the middle to represent the transfer of fluids into the bladder.
