The principle of healthy crystal cup is the magnetic field and energy field of crystal. Crystal is an energy stone with its own magnetic field and energy field, which can absorb and release energy. When we put water into a healthy crystal cup, the energy and magnetic field of these crystals will interact with water molecules, which will make the water molecules more easily absorbed by the human body, help to adjust the energy balance of the body, promote metabolism and so on, and finally achieve the purpose of purifying the body and maintaining health.
