Is there not contraindication with Green Tea and liver disorders?
Green tea is generally regarded as safe, however green tea extracts (supplement forms) are not recommended for those with liver failure. There are several case reports in which use of a concentrated green tea extract was associated with liver inflammation. In most cases, liver problems disappeared after the extract was discontinued. But, in two cases, permanent liver failure occurred. While it is not absolutely certain that the green tea extract caused the liver problems, nor how it might do so, these reports have raised concerns about use of green tea extracts, especially by those with liver disease.
