Signs & Symptoms of a Coriander Allergy

A coriander allergy is an immune system reaction to parts of the coriander plant, including the leaves (often called cilantro) and the whole or ground seeds. It may be caused by oral allergy syndrome.

Respiratory System

• A coriander allergy may affect the respiratory system, causing wheezing and trouble breathing.

Digestive System

• Effects on the digestive system may include nausea, vomiting, diarrhea, abdominal pain, or constipation.

Eyes, Mouth and Nose

• Coriander allergies may also cause swelling or tingling of the tongue, mouth or lips; itchy or watery eyes; and nasal congestion or runny nose.

Anaphylaxis

• In rare cases, an allergic reaction to coriander may result in anaphylaxis. Symptoms of anaphylaxis, a severe reaction, include rapid heart rate, dizziness and trouble breathing.

Oral Allergy Syndrome

• Many spice allergies are a result of oral allergy syndrome, or pollen-food allergy. Coriander is related to the birch tree, so people allergic to birch pollen may experience a mild and brief allergic reaction, such as itchy or tingling lips, to coriander.
