Kava, a depressive drug made from the roots of a plant in the South Pacific, plays an important role in the culture and economy of many Pacific nations but there is plenty we still don't know about it, according to Australian researchers. The team reviewed existing research into the drug to find out what we know about potential health risks and benefits, as well as the role of kava in culture and trade. The researchers say studies on the safety profile of kava are limited, and while there is evidence it may be helpful in reducing anxiety symptoms in the short term, there are potential risks of liver damage and brain damage in the long run. Concerns about liver toxicity have prompted bans on kava in several western countries, including some Australian states and territories, which the researchers say has economic impacts for Pacific countries.
