Hiya, CharleyAngels right, it's only leaf teas that we're allowed (nettle, green, peppermit etc) and black coffee.
No fruits, flowers or berrys. Which i was gutted about as i'd recently bought a load of different flavoured ones. Typical. lol.
Although whilst asking - i'm assuming raspberry leaf tea is allowed?? (i know there's the clue in the name but just thought i'd check lol). I've not had it yet but my sisters bought some for when i visit, infact my whole family have bought some form of different teas which is really thoughtful considering they all just drink normal tea. bless them.
