Just now tried it, let me say that I really underestimated this kava. I used a simple 3 tbs of kava per 8oz, and overall made 4 cups of kava. Cold water, strain, strain once more, and then had a shell. Then another shell. Right now, whoa, whoever said this kava felt a lot like stone was right on the ball there, my muscles feel like jelly and my mind is at a very simple and relaxed place, without that added edgy anxiety that for some reason, stone has given me each time. Honestly, I wasn't expecting very much from Rex but now I know better than to judge so quickly. I've tried many different varieties of kava, and as for powdered root, this so far is one of my favorites. Right up there with Hawaiian Kava Center's Moi and N@H Chief jungle.
