Arugula Allergy: Symptoms, Severity, and Management

Arugula (rocket) allergy is uncommon but possible. Reactions range from mild to life-threatening.

Symptoms

  • Oral allergy syndrome: lip/tongue/throat itching, swelling
  • Skin: hives, rash
  • GI: nausea, abdominal pain
  • Respiratory: wheezing, dyspnea
  • Anaphylaxis: throat swelling, hypotension, collapse—medical emergency

Mechanism

IgE-mediated; cross-reactivity with other Brassicaceae (mustard, cabbage) or pollen (mugwort) possible.

Action

  • Stop eating arugula if symptoms occur.
  • Seek immediate care for anaphylaxis (epinephrine, 911).
  • Consult allergist for testing and epinephrine auto-injector prescription if confirmed.
  • Avoid arugula and cross-reactive foods.

Most people tolerate arugula safely; it's nutrient-dense (vitamins K, A, C, folate, calcium).
