Found this interesting list of English tea substitutes in Kenneth Jaffrey’s Natural Foods. You can get a copy of the book at the Soil and Health Library.
There’s some interesting teas and preparation methods in this list.

Borage Tea: One more recipe I’d like to add to this list is The Herb Academy’s recipe for borage tea. It is believed to have some calming effects, useful for the treatment of nervous conditions.
