<P> A tea bag is a small , porous , sealed bag or packet containing dried plant material , which is immersed in boiling water to make a tea or an infusion . Classically these are tea leaves ( Camellia sinensis ) , but the term is also used for herbal teas ( tisanes ) made of herbs or spices . Tea bags are commonly made of filter paper or food - grade plastic , or occasionally of silk . The bag contains the tea leaves while the tea is steeped , making it easier to dispose of the leaves , and performs the same function as a tea infuser . Some tea bags have an attached piece of string with a paper label at the top that assists in removing the bag while also displaying the brand or variety of tea . </P>
