Calls for acupuncture needle quality control review

Researchers from RMIT in Melbourne used a scanning electron microscope to examine the surface conditions and other physical properties of 10 randomly chosen needles from each of the leading brands before and after a standard session involving needle manipulation.

The images revealed significant surface irregularities and inconsistencies, such as metallic lumps and small, loosely attached pieces of material at the needle tips. 

The researchers said that some of the fragments disappeared after an acupuncture session, which meant they could be could be deposited in human tissue, causing discomfort and potentially allergic reactions, such as dermatitis.
