It may also improve sleep in people with insomnia, often with fewer side effects than pharmaceutical or over-the-counter sleep aids. The compounds in kava root believed to offer mood-altering properties are called kavalactones. Little research has been done to pinpoint their exact mechanisms of action or evaluate which compounds are more active than others. The current body of evidence suggests that kava may aid in the treatment of anxiety, although there remains contention as to how effective a drug it really is.

According to a review of studies involving seven clinical trials and people, kava was deemed to be an "effective symptomatic treatment option for anxiety," even though the effect was considered "small" by the researchers.

Even though the WHO suggests that water-based kava beverages are "safer," the agency concedes that moderate to heavy consumption can significantly raise liver enzymes. The WHO also warned that toxicity appears linked to the quality of the raw kava root, contamination of the root during storage, and the use of other herbal drugs with kava.
