Research Summary

Kava has moderate short-term evidence for reducing anxiety, but rare serious liver injury has been reported, prompting regulatory caution. It is not a treatment for anxiety or insomnia and should be used only short-term, liver-healthy, and ideally with clinician guidance.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
