Tea

Tea is both a plant grown on Earth and a drink made of the dried leaves of the plant submersed in hot water and allowed to brew. It originating in Asia. Before it spread to the west, the average English person, such as Will Chandler, who came from 1643, had it explained to him by the Doctor as "a noxious infusion of oriental leaves containing a high percentage of toxic acid". The Doctor then professed that he rather liked it. (DW: The Awakening) It was later a favorite drink of the English and of the Doctor as well.
