These do energy healing. You can heal yourself or others. These pieces use a supernatural real psychic ability called energy medicine. This is the use of a universal energy that does only healing. When wearing the earrings it connects you to that stream of energy allowing you to project healing onto others as well as yourself.
To use these just wear them and think of what the health issues are and then you wipe them away with your thoughts and the use of the feminine universal energy.
These can only be used by women. You must have been born a woman to use them.
