The Kidneys are concerned with growth, development, aging, bones, teeth, ears, and sexual reproduction – the natural and harmonious unfolding of a life from birth to death. The Kidney Yin stores and circulates Jing, essence, throughout the body. The Kidney Yang is the metabolic fire of the body – the root of all physiological processes. Emotionally, the Kidneys are associated with will—the reservoir of self-knowledge and destiny that carries us through from birth to death. Kidney disharmony will manifest in improper development, sexual dysfunction, endocrine disorders and issues with the body’s metabolism.
