The majority of findings shows that specific kava extracts (standardized to 70% kavalactones) can lower anxiety and might work as well as prescription anti-anxiety drugs called low-dose benzodiazepines. According to one study, kava kava and diazepam cause parallel changes in brain wave activity, suggesting that they may work in the same ways to calm the mind. In 1988, the Alternative Medical Review reported that  four of the lactones in kava possess important analgesic and anesthetic property via non-opiate pathways.
