A reasonable amount of tea can actually be healthy since research has shown that tea, which is strong in flavonoids and antioxidants, can lower your risk of heart disease.  It’s also been linked to decreasing cholesterol and better blood vessel function.

Depending on the material with which it is adulterated, it might potentially be damaging to one’s health.

However, when tea is adulterated, the health advantages are not the same.
