I never knew that Kava could be so helpful in easing anxiety, I will most definitely be giving it a try;
"Kava (a.k.a. kava kava) is an herb that has been used to treat a variety of anxiety disorders. It is rated as "likely effective," for this use based upon review of scientific literature. In some studies, kava was found to possibly be as effective as low dose benzodiazepines (BDZ), a class of pharmacological agents commonly used for anxiety."
