“Herbal tea”, is a catch-all term for any non-caffeinated beverage made from the infusion or decoction of herbs, spices, or other plant material in water. These drinks are distinguished from caffeinated beverages like coffee, maté, kuding, and the true teas, as well as from decaffeinated tea, in which the caffeine has been removed.
In addition to serving as a beverage, many tisanes are also consumed for their perceived medicinal benefits. Like beverages made from the tea bush, tisanes can be served hot or cold. Tisanes have been used for nearly as long as written history extends.
Documents have been recovered dating back to Ancient Egypt and Ancient China that discuss the enjoyment and uses of tisanes. Among the Chinese, tisanes are commonly known as liang cha.
