I certainly hope your mother is being treated by conventional methods for her breast cancer. There is no scientific data that herbals can in any way treat cancer. If one chooses to use such preparations they should do so with the approval of their Physicians; mainly their Oncologist. I would advise you to have your mother discuss this with her Physician before continuing to use any over the counter suppliments. Regards.....
I would not do something that makes you bleed! Go see your doctor.
