ADHD is a common childhood disorder associated with concentration problems and disruptive behavior. Evidence suggests that herbal remedies may be as effective as standard drug therapies in treating ADHD symptoms. This study will determine the safety and efficacy of an herbal treatment in children and adolescents with ADHD.

This study will last 9 weeks. Participants will be randomly assigned to receive either an herbal product or placebo three times a day for the duration of the study. Participants will come in for weekly study visits at which their ADHD symptoms and any side effects will be assessed by self-report rating scales.
