The listing, Chinese Medicine Baoding Health Balls ~ Cloisonné Dragon & Phoenix 1.5" Vintage Set Good Condition has ended.
From a website:
The Production of these iron balls dates back to 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. According to the Chinese traditional medical theory of “Jingluo”, the hand contains a network of channels which circulate vital energy.
Acupuncture points are distributed along these channels.
Rotating the iron balls within our 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. In China, it is common to see a person using the Health Balls while taking a walk.
This is an older set in good condition.
The balls measure 1 1/2" across
