Many extracts used in foods are made of chemicals and are not at all natural. Allergies build to these chemical extracts over time. This is a list I use for muscle testing allergies to extracts but the most common extract allergies I see is are to vanillin, maple, spearmint, strawberry and “natural” butter extracts.
