Review of the scientific studies available:

The first scientific review article provides an overview of the traditional use and current research on kava, a plant used in traditional Pacific Islander ceremonies and increasingly popular in Western countries as a recreational drink and dietary supplement. The article discusses the potential health benefits of kava, such as its anti-inflammatory and anticancer effects and its well-known neurological benefits. However, the article also highlights the rare hepatotoxicity associated with certain kava preparations and the need for standardization and quality control measures. The authors emphasize the importance of further research into the molecular targets and mechanisms of kava’s effects and the need for well-designed clinical trials to maximize its benefits and minimize its risks.

Another scientific study is a systematic review and meta-analysis of the available evidence on the potential use of kava (Piper methysticum) as a treatment for Generalized Anxiety Disorder (GAD). The study found that evidence supporting kava as an effective treatment for GAD was found in two placebo-controlled trials and a reference-controlled trial, but one negative trial demonstrated that kava was not more effective than a placebo. Meta-analyses of the results of three placebo-controlled trials favoured kava for GAD treatment but without reaching statistical significance. The study suggests that kava may be an appealing treatment option for GAD patients who are more attuned to natural remedies or lifestyle approaches to reduce stress and that kava is safe and well-tolerated for short-term therapeutic use. However, the authors note that the current evidence is insufficient to confirm the effect of kava for GAD treatment beyond placebo and that new evidence is expected from a large, multisite ongoing trial.

This study looks at the risks associated with the use of kava, a plant used for traditional medicine and as an anxiolytic herb in Western countries. Some reports linked liver disease with the use of kava, leading to a regulatory ban for some kava extracts in 2002. The study analyzes clinical data from 14 patients with liver disease worldwide and found that kava, as well as other drugs and dietary supplements, may be hepatotoxic (toxic to the liver) in some cases due to overdose, prolonged treatment, and comedication. The poor quality of the kava raw material may also be a contributing factor. The study suggests that standardization is necessary to minimize hepatotoxic risks associated with the use of kava. (3)


In summary, Kava is a promising product to alleviate generalised anxiety and muscle tension. However, some caution must be exercised in relation to a risk for liver problems. It is always best to consult your healthcare provider before taking any medication.
