Hello, green tea is safe for most adults when consumed as a drink in moderate amounts or when green tea extract is applied to the skin as a specific ointment short-term. Green tea extract is possibly safe for most people when taken by mouth for up to 2 years, when applied to the skin as other ointments short-term, or when used as a mouthwash short-term. In some people, green tea can cause stomach upset and constipation. Green tea extracts have been reported to cause liver problems in rare cases. Green tea is possibly unsafe when taken by mouth long-term or in high-doses. It can cause side effects because of the caffeine. These side effects can range from mild to serious and include headache, nervousness, sleep problems, vomiting, diarrhea, irritability, irregular heartbeat, tremor, heartburn, dizziness, ringing in the ears, convulsions, and confusion. Green tea seems to reduce the absorption of iron from food. Drinking very high doses of green tea is likely unsafe. You can take 1 cup of green tea safely. Take care.
