Hippopot teas are made exclusively from dried herbs and (in some blends) fruits. We don’t use anything from the tea plant. As such, they are not really “tea”. The proper name is “tisane”. But most people call these herbal infusions, “tea”. And we are happy to go along with that. Just so long as you know that Hippopot teas contain no green or black tea, no caffeine, and certainly no additives or preservatives. Just natural herbs for you to enjoy!
