Crystal healing is often associated with other alternative and complementary therapies such as Ayurvedic medicine and acupuncture. The main value of crystal healing is said to be its ability to repair the underlying defects in thoughts and emotions from which disease is believed to originate. It is the role of the crystal or stone to re-align the body with this central energy, as this is thought to be the route to health. If you visit a crystal healer, he or she will place selected stones on various parts of your body. These locations reflect the meridians of acupuncture and Ayurvedic medicine.
Some crystals have the power to bend or refract light.
When a ray of white light is shined through a prism, the light is divided into all the colors of the rainbow. Crystals in quartz have that same ability. There is no scientific evidence that they can identify or cure any illness. Crystal healing serves no medical or scientific purpose. Despite these facts, however, some healers continue to claim that carrying crystals in one's pocket, wearing them on a chain around the neck, or placing them around the house brings the power of healing within reach.
