What is a tea bag?

A tea bag is a small, porous bag made of filter paper or other similar materials, containing loose tea leaves. It is designed to release the flavor and aroma of the tea leaves when immersed in hot water. Tea bags are commonly used for making a single cup of tea, and they are also used in teapots for brewing multiple cups at a time.

Tea bags come in various shapes and sizes, and they can be sealed or stapled closed. Some tea bags also contain additional ingredients such as herbs, spices, or fruits to enhance the flavor of the tea.
