The benefits of Dai Yu:
China has been known as "the country of jade" since ancient times. The ancients regarded jade as a treasure and regarded it as a precious ornament. Ancient medical books say that "jade is the beauty of stone, sweet, flat and non-toxic", and it is considered that jade is the most abundant substance in human body. It is believed that jade absorption, with the help of saliva and its synergistic effect, "produces fluid to quench thirst, removes stomach heat, soothes the boring place, nourishes the heart and lungs, moistens the throat and promotes hair growth." Therefore, jade is not only used as jewelry, ornaments and decorations, but also used for health and fitness.
