Hello!
Because I drink about 2 liters of herbal tea a day, this report http://www.hr-online.de/website/fernsehen/sendungen/index.jsp?rubrik=84369&key=standard_document_49982553 has made me wonder.
It would be nice if someone could comment on this, as I am quite unsure about the amount of tea I drink every day.
Greetings, Mood.
