Tea
From Halopedia, the Halo wiki
Tea is a type of beverage created by mixing hot water with certain leaves or herbs, which absorbs some of the contents of these leaves, giving the tea flavor and sometimes medicinal value.
Tea drinks are very common and popular among Humans, mostly for their taste. It is a standard choice on Food & Drink Dispensers which are standard throughout the UNSC Navy. It is served both hot and cold[1].
San 'Shyuum commonly prepare tea for medicinal purposes. Some San 'Shyuum vendors in High Charity sell certain herbs or leaves for medicinal tea to alleviate various sicknesses[2].
