The Crystal Healing Therapy, as in Crystal Reiki, uses crystals placing them on the body to promote physical, emotional and spiritual healing. Crystals do this by positively interacting with your body's energy field, or chakras. While some crystals alleviate stress, others improve concentration and/or creativity. Created over millennia, healing crystals harness the life giving elements of the Earth and the universe. Harnessing the energy of the Sun, the Moon, and the oceans, semi-precious stones connect us to Earth as soon as we come into contact with them.
