Some of the reasons why are:
- Normal day to day life depletes our Vitality.
- Excessive stress and poor habits can rapidly deplete it.
- Chronic stress and excessive emotional behavior, excessive sex, substance abuse, overwork, lack of sleep and poor diet all diminish Vitality.
This treasure is limited in quantity and when gone, it signals the end of physical life.
Foods and Jing
Most foods don’t contain enough condensed energy for building your Jing or Vital Essence on their own, and we all know most people don’t eat well to begin with. This accelerates the effect of stress on the body and it is easy to see how people get worn out. This is why it is very important to eat good Organic “Whole foods” that contain strong life energy.
Most adrenal formulas available on Supplement store shelves are helping to build Jing. While some formulas are much more effective than others, there are some herbs that work very well for building your Jing or vital essence.
My two favorite herbs for building your Jing or Vital essence are Goju Berry and Fo Ti.
Lycium Fruit (Goji Berry) 
This delicious tonic fruit is very widely used as an excellent Yin Jing and blood tonic. Regular consumption of Lycium is traditionally believed to lead to a long and happy life. It is said that prolonged consumption of Lycium will promote cheerfulness and vitality. Lycium is also said to brighten the eyes and improve vision. It is said that Lycium strengthens the legs and enhances sexual function. Lycium fruit contains polysaccharides that have been demonstrated to strongly fortify the immune system. Lycium is also very rich in vitamin C and in B vitamins. Furthermore, it is the richest source of carotenoids, including beta carotene, of all known plants on earth and is thus a powerful antioxidant. It is a very great woman’s herb.
He Shou Wu Root ( Fo Ti ) 
Constant consumption of this famous “longevity herb,” whose Latin name is Polygonum multiflorum, is said in the Orient to help return an aging person to youthfulness and to keep a young person young. It is an unsurpassed Yin Jing tonic, as well as a major blood tonic. It is said to increase energy and to clean the blood. As an essence tonic, it is believed to be a powerful sexual tonic when consumed regularly. He Shou Wu is widely believed in China to increase sperm production in men and to increase fertility in women. It is used in almost all tonics that are believed in the Orient to nurture the hair and teeth. This herb has been consumed by almost every Taoist that has ever lived, and is fundamental to the practice of the Taoist inner arts.
