In a Healthline report, medically reviewed by Seunggu Han, MD, it's advised that this idea does indeed come from acupuncture, the "ancient Chinese medicine-based approach" to treating various ailments by "triggering specific points on the body with needles," itself a common treatment for migraines. A daith piercing supposedly activates a pressure point similar to that used during acupuncture treatment.

However, the exact location needs to be specifically identified in order for the treatment to possibly work, so an acupuncturist would have to ensure that, first and foremost, the piercing is going in the right place. Generally, people who have had prior luck treating their migraines with acupuncture may be the most likely to go the piercing route for a more long-term fix.
