Are their any natural treatments to treat hyperactivity in kids?

Some, maybe: If hyperactivity is due to adhd, there are very few "natural" treatments of use. Most available natural treatments are combinations of ephedra, caffeine or ginseng. None of these are safer than prescription medications available, & some are actually dangerous for kids. Healthy diet, exercise, & sleep help everyone, including add patients. Caffeine, chocolate & red dye may cause hyperactivity.
