Resveratrol and Endometriosis

Hi there,

My girlfriend has been suffering from endometriosis for sometime now.

I was wondering if anyone had any advice regarding diet and supplementation that may help alleviate her symptoms.

In particular I would like to know what possible positive or negative affects could supplementing with resveratrol have?

Any help, advice, links, studies, etc, would be greatly appreciated.

Thanks in advance.
