Consumed for its relaxing/anxiety-calming effects throughout various Pacific cultures - including of course Fiji - it's made from the roots of the eponymous plant. A formal yaqona ceremony is often part of important social, political, or religious functions, and of course they're also performed for tourists. What's it taste like? I've never tried it, but I'm told it's "earthy" and slightly bitter, with some people comparing it to strong green tea, others to the flavor of wood or dirt. Hey, whatever gets you there, right?
