Amber Nawab, Najaf Farooq
Objective: to review and discuss the negative effects of green tea.
Green tea is obtained from Camellia sinensis andbelongs to the family theaceae and is used most popularly as beverage all over the world. Although there are beneficial effects of green tea, but it has also side effects. We have search different research articles and found that by consuming large amounts of green tea nausea, vomiting, dehydration, lethargy, central nervous system stimulation such as dizziness, insomnia, tremors, restlessness, confusion, diuresis, heart rate irregularities and psychomotor agitation may occur. Most side effects are due to high consumption of caffeine. Epigallocatechin-3-gallate (EGCG) has anti-folate activity so to prevent folate deficiency it should not used in excessive quantity and it may reacts with some drugs like aspirin and MAOI so used with caution if high level of green tea is used.
