Researchers from the State University of New Jersey found that too large doses of green tea can cause liver and kidney disease.

Green tea is considered a useful drink with many therapeutic effects. Nevertheless, according to the authors of the new study, this refers to the moderate consumption of tea - about ten small cups a day or two ordinary.

With more intensive use in the body increases the number of polyphenols, causing negative changes in the liver.

The authors give examples when an overdose of polyphenols led to death in rodents and dogs. They also refer to cases of human consumption of food supplements based on green tea, when symptoms of polyphenol poisoning appeared. When food supplements were withdrawn, the symptoms also disappeared.
