Possibly: Green tea is generally very safe & has positive effects on health. If you drink five or more cups of caffeinated green tea it can cause an increase in blood pressure for some people, as well as gastrointestinal upset (nausea or vomiting), irritability or insomnia. It can interact with some medications. It could aggravate anxiety disorders, diabetes & some bleeding disorders. Some teas >>>.

(especially black tea) contain tannic acid which if taken in large amounts can cause nausea, vomiting, GI upset & liver damage. Recommend decaffeinated green tea.
