Crystal therapy, which is said to date back to 25,000 BC, is a noninvasive treatment that uses vibrational medicine to facilitate healing. This therapy is based on the idea that the vibrations from a certain gemstone a client wears or carries can be felt by whoever is in close proximity to him. The crystal’s atomic structure allegedly acts as a template for the human body to follow, allowing the human energy field to change direction, absorb other energy, and focus on certain things more keenly.
