My colon dislikes every type of caffeine, herb, roibos, peppermint, green and white, decaf tea in all versions there are on the market except...Tetley. Tetley must have some special decaf technique that makes it gut-friendly for my gut. I can't even drink most de-caf coffee because they use chemicals to de-caffeinate and my gut rebels. The only decaf coffee I can drink is Paul Newmans Special Decaf, quite good.
I have a cabinet full of teas I've tried and failed with, dozens. The coffee gets drunk by my DH
I use coconut cream instead of milk and honey. It's almost a dessert and when it's "tea time" it's lovely with an almond walnut biscotti.
