Abstract

Introduction: Green tea is heavily promoted and sold over the counter for many illnesses, including obesity.
Methodology: Literature was reviewed focusing on the key words; tea, green tea, catechin, overweight, obesity, side effects, adverse effects, transient ischemic attack, stroke and liver function, up to December 2014.
Results and discussion: Majority of the studies on this topic were short term and involved only a small number of participants. Though these studies demonstrated very small reduction of weight, evidence was inadequate for the use of green tea as an anti-obesity agent. In this review, the effect of green tea on obesity and some possible harmful effects of green tea are discussed. Current evidence on green tea does not support the use of it as an anti-obesity agent. There are several reports of side effects. The liver side effects are a cause for concern.
Conclusions: Long term use of green tea as over the counter supplement should not be encouraged. Rather it should be considered a drink, very much like any other tea or coffee, till further evidence of efficacy and safety are proven.
