Tea bags are usually made of cellulose, which contains harmful substances such as chemicals and residual pesticides. These chemicals may be dissolved in tea when making tea, and then absorbed by the human body.
In addition, tea bags are usually packed with plastic materials, which may also be harmful to health. Chemical components and plastic particles in plastic packaging may penetrate into tea and be ingested by human body.
Therefore, it is suggested to choose environmental protection tea bags made of natural materials such as non-woven fabrics or use tools such as tea filters to make tea to avoid the potential harm caused by tea bags to the body.
