The Taoist needle is made entirely of brass, to which it owes its solidity and weight. Taoist needles are used as an alternative to traditional acupuncture needles for non-invasive impact on acupuncture points in acupressure treatments. The heavy weight of the Taoist needle means that it does not require a lot of force to use it, because its weight itself affects the acupuncture point, without piercing the skin like a classic acupuncture needle.
