How in the world do you retain all of this knowledge, Nat? I am sooo impressed!!! thanks very much for the info, I also checked out Doreen's link in another thread, very informative!! It's good to know that as an added bonus, it may help dissolve gallstones (my latest torment). This looks like very good stuff although rather icky tasting. I think I'll develop a taste for it though. Thanks very much for the search tip, Nat.
