The liver and kidney

The liver stores blood and the kidney stores essence. Liver blood relies on nourishment by kidney essence, and the kidney essence relies on the supply of liver blood. Essence and blood produce and supply each other, hence the saying " essence and blood have the same source, " and " the liver and kidney have the same origin. "

Pathologically, when deficiency of kidney essence deprives the liver of nourishment, it will lead to deficiency of liver yin, resulting in " deficiency of yin of both liver and kidney. " Clinical manifestations may include soreness and weakness of the lumbar region and back, seminal emission, tinnitus, dizziness, vertigo and dryness of the eyes.

If there is hyperactivity of liver yang, there may be headache, redness of the eyes, and irritability. In prolonged cases, if kidney yin is also consumed, there may be soreness and pain of the lumbar region, seminal emission and tinnitus
