As long as the food or supplement doesn't destroy platelets, then it depends on what her bleeding symptoms and times are. Several years ago, I had a full work up for Von Willebrand disease which is a disorder in the clotting factors. I was negative for Von Willebrand, but the bleeding time test with the "coffee filter" was over 10 minutes and the blood test came back as having an "asprin-like" subsubstance that impacted the clotting. After some digging, the doctor and I contributed taking a multi-vitamin with ginko-buloba as the likely culprit. When my counts crashed 18 months ago, I stopped taking a strong antioxidant heavy in grape seed extract. Whether or not it was a contributing factor, I'll never know.
I don't think that occassionally eating them would be an issue if she doesn't have bleeding issues. I consume many of the items on the list, I've just stopped the consistent daily intake. Much like I avoid ibuprophin most of time, but if I'm really suffering from muscle imflamation I'll do a few as needed.
