At the Allergy, Asthma, and Sinus Center of Long Island, we often encounter questions about whether spices can cause allergic reactions. Spices, integral to our diets, are derived from plants, making them potential allergens. However, it’s crucial to distinguish between true allergic reactions, which are rare and can be life-threatening, and more common non-allergic reactions or intolerances that are usually self-limiting.

Understanding Non-Allergic Reactions to Spices

Non-allergic reactions to spices do not involve the immune system’s production of allergic antibodies and are typically less severe than allergic reactions. Common non-allergic symptoms include:

Skin Irritation

• Example: Cinnamon might cause a local rash upon skin contact.

Oral Itching

• Example: Fresh tarragon may cause itching in the mouth due to cross-reactivity with certain pollens, not the spice itself.

Respiratory Symptoms

• Example: Inhalation of black pepper can trigger coughing or exacerbate asthma symptoms, likely due to its irritant effect rather than an allergy.

Recognizing Allergic Reactions to Spices

Although rare, spices can cause severe allergic reactions, including anaphylaxis. True allergic reactions are immune responses to the actual spice. Notable examples include:

• Anaphylaxis reported with spices like oregano, thyme, coriander, caraway seed, cumin, and cayenne pepper.
• Contamination issues, such as spices adulterated with peanuts, have led to recalls but no reported reactions in peanut-allergic individuals to date.
• Sesame seed, a recognized food allergen, may be present in spice mixtures and pose a risk to those with sesame allergies.

The Importance of Professional Diagnosis

If you suspect a spice is causing allergic symptoms, consulting with an allergist/immunologist is essential. At the Allergy, Asthma, and Sinus Center of Long Island, we utilize skin prick testing and, in some instances, oral challenges to accurately diagnose spice allergies. These methods help determine if an allergic antibody to the spice exists, guiding appropriate management and future dietary choices.
