The Tea is a very special item that allows players to gain access to Saffron City. Without the Tea, players will not be able to proceed into Saffron City after saving Mr. Fuji in the Lavender Town Pokemon Tower. And without having access to Saffron City, one can't defeat Team Rocket in the Silph Co. Building and thus will not be able to proceed much further in the Main Story. Unlike other items, the Tea is pretty easy to obtain. In order to do so, all you must do is peak to the Elderly Woman in the Pokemon Mansion found with Celadon City. It's just that easy!
