Can you tell me if there are any natural treatments, herb or otherwise, to treat hyper activity in kids?

Best natural tx. The best, most evidence based, natural treatment to improve the symptoms and impact of hyperactivity (adhd) is to limit screen time. In other words, turn off the tv, turn off the computer, put away the tablet and the smart phone, turn off the video games. Restrict to one hour on weekdays and two hours a day on weekends. Go to the park, play catch, read with them, have a conversation.
