Kava for a Child's Overactivity?

I have a son who is almost 5 and we need help. He is VERY active and medications do not work. He has a chromosome problem. We are using KAVA KAVA at 530 mg a day. We have tried GABA and it to worked but only for a while. His body must have been getting used to it. After giving his body a month or so break and starting again it worked again. I am looking for i information on KAVA KAVA. How much to use. He weighs 44 lbs. Any ideas or help??? on this matter.

The diet has important effects on activity. I recommend that you see previous answers regarding overactivity in children diagnosed with Attention Deficit Disorder on our website at www.richters.com. Go to the "Q&A" area, choose "Search Richters Q and A" and enter the word "attention" for the search. . Dosages for recommended herbs are included in these items. As well as working with his doctor, I suggest that you work with a qualified holistic health care practitioner who can guide you in finding out what deficiencies your son has and suggest a balanced approach to his health.
I probably wouldn't recommend Kava Kava. I suggest something more gentle that can be used long term, such as Chamomile. There are many books now available on Kava Kava. At Richters, we have "Kava: The Pacific Elixir, The Definitive Guide to its Ethnobotany, History and Chemistry" available for order.
