Don't forget though - she may have an issue with nuts as well. That could be the allergic reaction she's experiencing. They are supposed to be below a certain ppm of gluten but I think there's always a chance for cross contamination. If it says gluten free, you can test it and see if you have any issues. I wouldn't assume because you're friend had a reaction that it's a gluten one. It may very well be another reaction to something else.
