It's a rather interesting review of at least some of the major studies (conducted up until 2011) . Unfortunately, the authors do not seem to be aware of either the issue of kava adulteration (with aerial parts or other stuff) or the whole tudei controversy. I am becoming quite convinced that the omission of such important variables from these studies makes them potentially very misleading and possibly highly inconsistent. I am wondering if new studies will take these issues into account.
