Kidney 肾
The Kidney stores Jing — the constitutional essence that governs growth, ageing and reproduction — and governs water metabolism.
Pinyin: Shen · Five Element: Water · updated
The Kidney is where the body's deepest reserve sits. It stores Jing, the constitutional essence that determines the trajectory of growth, maturation and ageing, and it governs water metabolism and the reception of Qi. In classical terms this is the organ most associated with what you were born with rather than what you have built.
Kidney patterns divide into two directions. Kidney Yin deficiency is the hot, dry, thin picture: night sweats, dry mouth, heat in the palms and soles, tinnitus, back soreness with restlessness. Kidney Yang deficiency is the cold picture: chill, low libido, clear urine, fatigue that responds to warmth. Many people show features of both.
Its element is Water, and its season is winter. Because Jing is finite, the classical emphasis is on preservation rather than building: adequate sleep, moderate exertion, and protecting the lower back and feet from cold. The hour from 5pm to 7pm is the Kidney's own period, traditionally used for gentler effort and winding down.

Patterns that often appear alongside this one
Yang Deficiency
Yang deficiency is insufficient warming function — you feel cold, digest slowly, and move with less spark than the seasons call for.
Yin Deficiency
Yin deficiency is insufficient cooling, moistening fluid — you run warm and dry, and rest does not fully restore you.
Qi Deficiency
Qi deficiency means your defensive and transformative Qi runs low, so ordinary effort costs more than it should and colds come easily.
Yang
Yang names everything warming, activating, expanding and outward-moving — the half of the pair that drives change and defends.
Yin
Yin covers everything cooling, moistening, contracting and substantial — the half of the pair that sustains and contains.
