According to reports, German scientists say that tea bags contain ingredients that could be harmful to human health.
German researchers say the paper from which the tea bag is made contains substances harmful to human health and in some cases can cause cancer.
The tea bags of 6 companies were examined in different ways, three of which were expensive and three tea bags were from the cheap company. Research has shown that a substance called epichlorohydine is included in the paper which is used to make tea bags and this is what makes it harmful to health.
Wrapping tea bags in bags and putting them in boiling water contains harmful substances in the water which can cause cancer. It is better to use tea leaves directly than tea bags.
