What is the difference between Lipton tea and natural tea?

Lipton tea is one particular brand of tea. The term "Natural Tea" is not well-defined and is not a mainstream term. Tea companies often throw around the Word "natural" because it has a positive connotation--but the Word is almost meaningless in the world of tea. Sometimes tea companies and tea enthusiasts use the term "pure tea" to refer to teas that are made exclusively from the tea plant (Camellia sinensis), and contain no flavorings or other ingredients.

By this definition, the basic Lipton tea is a pure tea as it is made exclusively from the tea plant and contains no flavorings or other ingredients.

However, Lipton also sells a number of other teas, which have flavorings, and also other ingredients such as various herbs and spices. These include both flavored teas, which include tea with other ingredients, and herbal teas, which do not include the tea plant.
