Dark circles under the eyes may be related to both the liver and the kidneys as described in Traditional Chinese Medicine (TCM). The liver opens the orifices of the eyes, and the eyes have a lively look, which comes from the liver and blood. Dark circles under the eyes are often characterized by deficiency of liver blood and inflammation of deficiency fire. Chinese medicine emphasizes that “the essence of the five viscera and six bowels are all injected into the eyes”, if you stay up late for a long time, stress, or lack of sleep, etc., will result in insufficient liver blood and inflammation of deficiency fire, appearing dark circles under the eyes. The kidney is the main water, the main closed hide. If kidney yang is weak, resulting in unfavorable qi, then the water upward, stagnant in the eye area, that will lead to water rings. Kidney is black in color, which turns into dark eye circles. Moreover, liver deficiency will also lead to kidney deficiency, and insufficient liver blood will also lead to insufficient kidney yin, which will lead to the upward movement of fire. Dark eye circles have something to do with liver and kidney, so you need to pay attention to live a regular life and nourish your liver and kidney.
