accessed 17 November 2006 (JS) A 2006 update of the 2003 Cochrane review was performed evaluating randomised, double blind controlled trials of rigorous methodology using kava mono-preparation in anxious conditions. The review discovered 12 trials that met the inclusion criteria (total number of patients = 700), 7 of which were used in a meta-analysis using The Hamilton anxiety scale (HAM-A) as the outcome measure. The results of the review documented a statistically significant anxiolytic effect of kava compared to placebo in all but one trial, with the authors concluding that kava is an effective short term treatment of anxiety. The meta-analysis of 7 homogenous trials demonstrated that kava reduced anxiety significantly over placebo as assessed via HAM-A (weighted mean difference 3.9 over placebo on the HAM-A; 95% CI: 0.1 to 7.7 p= 0.05; n=380). The average amount of kavalactones (the active constituent) used in the studies was between 105 mg-240 mg during a 5-7 week period, with no cases of hepatic toxicity reported in any of the trials.
