Warning on Kava
Kava, an extract of a species of pepper plant (Piper methysticum), is widely touted as a natural alternative to antianxiety medications. Though some clinical trials have found that it works, possibly by a mechanism similar to that of benzodiazepines, there are concerns here and abroad about its safety.
The Food and Drug Administration is investigating reports that it may cause serious liver toxicity, including cirrhosis and liver failure. About 25 people in Germany and Switzerland developed liver toxicity after using products containing kava.
The FDA has also received several reports of toxic reactions in this country. In one case, a previously healthy young woman required a liver transplant after taking a dietary supplement containing kava. In addition, there was a report several years ago of a patient falling into a coma after using kava with the benzodiazepine alprazolam (Xanax).
Following these reports, Germany and Switzerland banned the sale of kava. It’s still available in the United States, but in light of the potential danger, you should avoid this herb.

Thanks for the warning Jan. Sometimes it is easy to think that all natural remedies are benign and forget that most of our drugs came from plants to begin with.
I've had some good luck with herbs, but you do have to be careful.
