3.1 Needle quality
Stainless steel is the material of choice for acupuncture needles. Each should be carefully checked before use. If it is bent, the shaft eroded, or the tip hooked or blunt, the needle is defective and should be discarded.
It is recommended that the quality of manufacture of acupuncture needles be controlled by the national health authority.
