A daith (pronounced /ˈdʌθ/) piercing is an ear piercing that passes through the ear's innermost cartilage fold, the crus of the helix.[1]
The piercing is usually performed with a straight hollow needle. Captive bead rings are the most common jewellery type used. It can take from six to nine months for a daith piercing to heal.
Some people believe that daith piercings can cure chronic migraines and anxiety in people. However, there is no evidence for this claim and any reported effects are attributed to the placebo effect.
