Negatives of Green Tea
The major concern with drinking too much green tea is the caffeine it contains. Too much caffeine can cause nausea, insomnia or frequent urination.
New Scientist points to recent research has shown consuming very large quantities of green tea can be dangerous as it can cause damage to the liver and kidneys:
Green tea is good for you, but only if drunk in moderation. While the polyphenols in green tea are credited with preventing heart disease and cancer, it seems they can cause liver and kidney damage if consumed in very large quantities, a review of studies into the toxicity of polyphenols has shown.
He stresses that up to 10 small cups of green tea a day is fine. Problems are likely in people who take supplements, which can contain up to 50 times as much polyphenol as a single cup of tea.
In summary, keeping drinking green tea for its numerous benefits but the benefits of taking supplements may outweigh the risks.
