Lithotherapy is a pseudoscience based on the belief that stones and crystals can heal by emitting imperceptible vibrations that resonate with the skin. It has origins in traditional medicines from places like India, China, and Tibet that ascribed magical or therapeutic properties to minerals. While proponents claim it can harmonize and rebalance the body, there is no scientific evidence that the stones themselves cause any effects beyond placebo. Lithotherapy is generally considered safe if used lightly as a complement rather than substitute for medical treatment. Adherents recommend choosing and using different stones based on their associated properties to target various ailments.
