Kidney Essence Deficiency

肾精不足 Shen Jing Bu Zu Kidney system

The deepest reserve of the Kidney, the one that builds bones, teeth, marrow, hair, and the brain, has worn thin. Teeth loosen early, bones weaken, hair greys and thins, memory slips, and in a child growth runs slow.

Yin and yang are the water and the fire. Essence is the well they both draw from. When the well is low, the things built from it, teeth and bone and hair and marrow, are the first to show it.

How Kidney Essence Deficiency differs from its look-alikes

  • Kidney Yin Deficiency Yin deficiency is warm and dry and can be fairly new. Essence deficiency is structural and slow: bone, teeth, hair, growth. Essence deficiency usually needs the heavier animal and seed tonics on top of the rehmannia base.
  • Kidney Yang Deficiency Yang deficiency is cold: cold limbs, pale face, clear frequent urine. Essence deficiency may show as warm or cold depending on which side has worn down more, but the bone and teeth signs point to essence.

  • Daily tooth tapping: tap the teeth together lightly thirty-six times on waking, then swallow the saliva. The old Kidney practice for the teeth.
