I have no problem with using alternative medicine to treat ADHD, as long as the parent clearly understands the consequences of the treatments.
Since many children don't get much benefit from conventional medicine, I can see why they would look at alternative medicine to help their child.
However, with little boys especially, before I considered too much in the way of medication or alternative medicine, I'd get a referral to a pediatric ENT and see if I could get a sleep study done on my child. I saw a news magazine that covered a little boy who was seven and barely reading on a kindergarten level. He was diagnosed with ADHD and his mother noticed he was snoring a lot. She took him to a pediatric ENT, who ordered a sleep study. The child was waking up something like 20 times an hour. Turns out, his tonsils and adenoids were greatly enlarged.
The ENT scheduled him for surgery and removed the tonsils and adenoids. In six weeks, he was reading above grade level and was off all medication.
Seems like the ADHD diagnosis has become much more common as the incidence of removing tonsils and adenoids has decreased. But I'd check that first. Sleep deprivation can cause the same symptoms as ADHD.
