Crystals are a subtle healing force. Highly effective in hyper-sensitivities. Children among others most certainly benefit from the use of crystals.
Crystals have been used for a millenia to heal and bring balance. They work through resonance and vibration. Crystals heal holistically, they work on the physical, emotional, mental, and spiritual levels of being. They realign subtle energies and dissolve disease, getting to the root of the cause.
