Query: Sad But True

In a recent video (At Home With Paul Beryl), the author admits that he didn't know as much about herbalism in 1984 that he apparently wishes he had known. I admire the honesty but would feel disappointed if I had this 1984 edition. Don't buy this. Get his newer one.As for the quality of his books in general, they totally rock. He really is considered the best of the best when it comes to books herbalism. Just don't buy his video. It's really has very little usable information.
