The most common side-effects appear to be gastrointestinal upset and headaches. HEPATOTOXICITY

A systematic review assessing the safety of kava which included a total of 7078 patients taking kava extract equivalent to 10 mg to 240 mg kavalactones per day for 5-7 weeks identified no cases of hepatotoxicity (Stevinson et al 2002). Considering that case reports of hepatotoxicity exist, they should be considered a very rare event based on the evidence.
