Eating jade is good for your health. The health-preserving mechanism of jade has been confirmed by modern science. According to chemical analysis, jade contains many trace elements beneficial to human body, such as zinc, magnesium, iron, copper, selenium, chromium, manganese and cobalt. Wearing jade can make trace elements absorbed by human skin, activate cell tissue and improve human immune function. Therefore, some Chinese medicine practitioners say that "some diseases can be cured not by taking medicine, but by wearing jade often", which is the truth.
