Chinese name: 肾精虚
Pinyin name: Shèn Jīng Xū
Kidney Essence (Jing 精) Deficiency usually involves Deficiency of Kidney Yin and, to some extent, Kidney Yang. Its signs manifest in relation to growth, development, reproduction, sexuality, bones, marrow, the brain, teeth, memory and hair. Poor hereditary constitution in children, aging, excessive sexual activity or Kidney Yin or Yang Deficiency over a prolonged time may leads to Kidney Essence Deficiency.
In children, this pattern is almost always caused by a hereditary weakness of the Kidney Essence, which can be due to parents being too old or in poor health at the time of conception. In adults, this pattern may be caused by excessive sexual activity. In women, a Kidney Essence Deficiency may be a result of prolonged loss of Blood over many years, such as excessively heavy periods. In women, it may also cause Liver Blood Deficiency as Essence participates in Blood making.

Diagnosing a pattern in Chinese Medicine is no easy feat and should be left to professional practitioners.
In particular one has to know how to differentiate between different types of pulses and tongue coatings, shapes and colors. Here patients with Kidney Essence Deficiency will tend to exhibit empty (Xu) or floating (Fu) pulses as well as a pale tongue with complete absence of coating.
Practitioners also learn to read from a long list of seemingly unrelated symptoms. Here patients with Kidney Essence Deficiency might experience symptoms like poor bone development, late closure of fontanelle, weak limbs and hair loss (full list here above).
