Yes, I actually drink "Kava Stress Relief" tea (it has kava but also mixed with cinnamon, sarsaparilla, cardamon, ginger and carob pod). It's very tasty. But I did have to get it across the border as it is indeed illegal here in Canada (kava). And yes, the box does specifically state to see your doc if you drink alcohol frequently or have liver issues.
Ya..I didn't ask anybody : )
