Around age 7 we tried acupuncture for the ADHD. My child was less than cooperative. In all we had about 5 appointments.
The acupuncturist was smart, funny, educated… my child was not wanting the treatment. He refused many needles, other than the most essential ones.
The practitioner patiently used moxy which was a smoke / heated energy tool.
We had those tiny band-aid needles placed into the ear at the end of the appointment, those stayed in place for a few days afterward.
I saw little effect on attention- add to that the stress over the appointments we went to meant those treatments needed to end.
