Thank you for the clarification. I personally have never drank kava or used any sort of kava derived product, but I have used Erowid to great benefit concerning a wide range of other substances and thought that the information there would be up to a similar standard. Still, there is information there that echoes what you’ve outlined in your comment - so it doesn’t seem like it was all hooey.
How does that saying go? The road to good answers is paved through Cunningham’s law? :)
