Jade nourishes people: Jade contains more than 30 kinds of trace elements beneficial to human body, such as selenium, zinc, nickel, cobalt, manganese, magnesium and calcium, which can promote blood circulation, enhance metabolism and eliminate waste in the body. Jade can also turn drinking water and natural water into active water, helping the human body to improve immunity. According to the eighth volume of Compendium of Materia Medica-Epistemology, jade has the following therapeutic effects: removing stomach heat, relieving asthma, nourishing hair, nourishing five internal organs, softening tendons and strengthening bones, quenching thirst, moistening heart and lungs, helping voice and throat, calming the heart and calming the nerves, benefiting blood vessels and brightening eyes and ears. People raise jade: jade absorbs the oil and heat secreted by people in the long-term contact with the human body, and will become more and more moist. And people wear it for a long time, and the color of jade will get darker and darker. If it is bright white jade, containing violet or a dark green, the green will gradually become thicker, and the faint blue will be very clear, as if people have brought jade to life.
