Having done 3 different trips to Fiji, and bought the REAL kava freshly ground up from the roots, I can attest to the mellowing qualities of it, sorta like drinking muddy water, numbs the tongue, and puts a nice glow on your attitude. They drink it daily down there, and it's the real stuff not some fake powered in a pill.
I brought home a BUNCH of the stuff, maybe it's time later today to go make a batch for fun.
Buying it from the locals at the produce market, how can you say no to the lady who is proud to claim, "My Kava is Number 1 best!"
