Contact and systemic contact-type dermatitis to spices.
Contact and systemic contact-type dermatitis reactions to spices such as nutmeg, mace, cardamom, curry, cinnamon, and laurel may be rare but may well be overlooked. In our experience, patch testing with these spices "as is" is very useful; if there is a positive reaction, testing with dilutions is helpful. Scratch-chamber testing often leads to false-positive irritant reactions. As Hjorth and Niinimäki have pointed out, a positive test to balsam of Peru may indicate a spice allergy, but the absence of such a reaction does not rule it out. In all the cases in our experience, the careful drafting of the anamnesis or case history was critical in the diagnosis.
