Side Effects:None identified associated with consumption of up to 20 cups/day. Excessive consumption of caffeine is known to cause typical effects, such as nervousness, insomnia, and restlessness in some individuals.

Drug Interactions:

EGCg displays anticoagulant activity due to inhibition of platelet aggregation, so individuals taking aspirin or other anticoagulant substances on a daily basis should consult with their physician. Green tea has shown synergistic antitumor activity with tamoxifen, suldinac and doxorubicin..

Special Precautions EGCg may provoke an allergic reaction in some; animal studies have also shown an anti-allergic action for this constituent. Patients on potassium-restricted diets should avoid excessive consumption of green tea, which is high in this nutrient.
