    I have a severe food intolerance for flat leaf parsley, and white onions – especially Maui onions. Is there any chemical compounds that they share?, in that my gastro intestinal reaction is the same.

    I get indigestion from onions [raw and cooked] and garlic. Acid reflux from cinnamon and nutmeg. Diarrhea from oregano. Any correlation? Thanks
