The intrinsic vibration of water is essential to our health. Unfortunately all focus on water is what it is containing. Water has a memory and all negativ energy it absorb are reducing the energy of the intrinsic vibrations and when so the cells possibilty to communicate with each other become difficult. That is how a disease will occur when vital cells in organs can`t receive and send information.
