Herbs for Attention Deficit Disorder Not in Ragweed Family

I have an 11 year old boy with ADHD and an 8 year old girl with ADD. They are both very anxious children. My boy is allergic to ragweed and pollen and grasses group B. Chamomile is part of the ragweed family, so I can't give that to him. Any suggestions about something I could give them? I would prefer to sooth them naturally. They love herbal teas.
