The production of these iron balls dates back the Ming Dynasty (1368-1644). The inside is hollow and each ball has a sounding plate inside. One emits a high tone, the other a low tone. Rotating the iron balls within your hand stimulates the acupuncture points- leading to better circulation (and unlocking vital energy). The Health Balls are placed in the palm and then rotated in a circular manner.
