For instance, a Root Chanel Inflammation of a tooth. In the beginning, you feel uneasy to bite on this tooth. You feel pain when you press on the gum or hitting with the back of a spoon against the tooth
In this state, you can heal the Root Chanel Inflammation with chewing cloves, ice cubes and to lead the energy from the tooth down to the Lower Dantien. If it is getting worse, Colloidal Silver or Antibiotic will help.
