Crystal healing is an ancient medical technique in which crystals and other stones are used to cure ailment, infirmity, illness and prevent against disease. Proponents or followers of this technique believe that crystals act as conduits and help in allowing the flow of positive energy and heal negative or disease-causing energy from the body. Throughout all of history, crystals have been used as a source of healing power.
Although a crystal healing technique has seen an upsurge in terms of popularity in recent years, this ancient treatment is not popular among most medical doctors and scientists. They refer to this technique as a pseudoscience. Moreover, there is no scientific evidence that states that crystal healing can be used to cure diseases, because till now this fact is not proven that negative energy flow leads to diseases in the human body. Likewise, crystals and gems can be distinguished on the basis of chemical composition or color to treat a particular ailment, is yet to prove scientifically.
Nevertheless, healing crystals remain popular at health spas and at New Age health clinics, sometimes assimilated into related practices of massage and Reiki. The use of crystals in such environments may help to induce relaxation, although this effect is also not backed by scientific evidence.
