Cautionary statement concerning green tea extracts

On June 26, 2007, the U.S. Pharmacopeia (USP) Dietary Supplements Information Expert Committee (DSI-EC) voted to require cautionary statements on the labels for green tea extracts.
 
The new labeling requirements came about after the USP DSI-EC reviewed numerous case reports suggesting a potential link between ingestion of products containing green tea extracts and liver damage. The original rating did not require cautionary statements.
 
The cautionary statement required on dietary supplements with green tea extracts will read:
Caution: Must take with a meal. In rare cases extracts from green tea have been reported to adversely affect the liver. Discontinue use and consult a healthcare practitioner if you have a liver disorder or develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice.

Have any of these findings been associated with green tea itself (or black tea for that matter), or just extracts?

Just curious but taking something like Milk thistle that helps the liver...would that help against this possibly happening?

"The only failure that is final is to stop trying to improve"

I think it has to do with the nature of the extract when taken alone.  Thus, "Must take with a meal."

One of the most important constituents of milk thistle is silymarin.  While Silymarin is thought to act as a liver-protectant.  I don't think the milk thistle can be relied on in this instance.

When you drink green tea, the active constituents we are talking about are something like 1.5% of what you consume.

When taking an extract, the amount of the active constituent is as much as 90% of what you consume...that is 60 times stronger.  The liver is responsible for processing that.  Not necessarily a problem but there are obiously enough people who do experience problems that it is worth mentioning.
