Kava (Piper methysticum) is a plant native to the South Pacific, traditionally used for its calming and anxiolytic effects. Recent research has focused on its potential as a treatment for anxiety disorders, particularly generalized anxiety disorder (GAD). This synthesis aims to present the key findings from multiple studies on the efficacy and safety of kava in reducing anxiety.

Long-term Efficacy and Safety:
The current body of research supports the use of kava as an effective short-term treatment for anxiety, with multiple studies demonstrating significant reductions in anxiety symptoms compared to placebo. Kava is generally well-tolerated, though there are concerns about potential serious adverse effects, particularly liver damage. More extensive and long-term studies are needed to fully understand the safety profile and long-term efficacy of kava in treating anxiety disorders.
