Jing’s multiple meanings in Chinese medicinal theory
- Jing is a collective term for Prenatal Jing and Postnatal Jing, the fundamental substances that build up human body and sustain body’s vital activities.
- Jing is Prenatal Jing.
Prenatal Jing is in charge of human’s reproduction. The Jing is inherited from parents. It forms a life beginning with an embryo and nourishes the embryo till birth. Sperm is“Jingzi”in Chinese. The Jing is store in kidney.
- Jing is Postnatal Jing.
Postnatal Jing comes from the foods and water we eat and drink. Stomach digests and decomposes foods and water into chyme and distributes chyme to small intestine. Small intestine digests and transforms chyme into food essence and distributes food essence to spleen. Spleen digests and transforms food essence and Prenatal Jing (distributed by kidney) into Postnatal Jing and distributes Postnatal Jing to Lung. Lung transforms Postnatal Jing and nature’s air into human body’s chi (Zong Chi、Ying Chi and Wei Chi). Ying Chi and Zong Chi, then, get distributed to heart and flow in blood vessels. Beside transforming into chi, Postnatal Jing also flows in blood vessels and nourishes body systems; free Postnatal Jing is stored in kidney and whenever organs need, kidney distributes this Jing to organs to sustain organs’ physiological activities.
- Jing is also a collective term for Jing、blood and fluid.
- Prenatal and Postnatal Jings drive body growth and development.
Prenatal Jing forms a life beginning with an embryo and nourishes the embryo till birth. After birth, the Postnatal Jing continues to nourish the body for growth and development. Both Jings decrease along with aging, meaning that every human being will experience the process of birth, childhood, adulthood, old age and eventually death.
- Postnatal Jing produces marrow and transforms into blood.
Postnatal Jing stored in kidney can transform into marrow. Marrow includes brain、spine marrow and bone marrow etc. If a person has a healthy amount of marrow, his bones and teeth will be strong and he moves with agility. Marrow can transform into blood. So, a person with insufficient Kidney Jing could have anemia and other health problems. That is also why most of the elder have pale complexion because of decreasing kidney Jing.
- Postnatal Jing nourishes and moisturizes body organs.
Kidney not only stores Jing but also distributes Postnatal Jing out to nourish and moisturize body organs. This cycle of storing and distribution is a continuous process as long as life stands.
