Garlic Allergy


Key Allergens

Garlic is a well recognised cause of allergic contact dermatitis and urticaria. Patch testing using neat garlic can cause false-positive reactions because of diallyl disulfide found in the bulb acting as an irritant on the skin.

Diallyl disulfide is used as a garlic flavouring in food and garlic oil.
