The Safety of Green Tea Extracts

Grapefruit or grapefruit juice, once in a while, in moderate quantities, probably not a problem. But the more concentrated things that you might be taking because you've heard they're good for you could also be kind of a problem. For example, green tea concentrate. These very concentrated extracts are mostly designed for people who are trying to lose weight or use it for energy. They can cause problems with the liver if taken on an empty stomach.
