Jing in Traditional Chinese medicine refers to the essential energy in the body, it specifically targets the male sexual fluid and hereditary essence of the female. Jing is stored in the kidneys and is yin in nature, which means it nourishes, fuels, and cools the body.
Production of semen, in the man, is believed to place a great strain on Jing energy while the monthly cycle of the woman is said to do the same. When depleted, it can lead to tiredness, lethargy, sore joints, and a loss of drive. When Jing is full, potency is increased, libido is increased, the climax is more intense, and rebound is quicker.
