Herbal teas—less commonly called tisanes (UK and US /tɪˈzæn/, US also /tɪˈzɑːn/)—are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Perhaps some of the most known tisanes are actual, true teas (e.g., black, green, white, yellow, oolong), which are prepared from the cured leaves of the tea plant, Camellia sinensis. Besides coffee and true teas (they are also available decaffeinated), most other tisanes do not contain caffeine.
