Question 1

What is Coriander/Cilantro Allergy?

Accepted Answer

Coriander/cilantro allergy is an immune system reaction to proteins found in the coriander plant and its leaves (cilantro). It is caused by the production of immunoglobulin E (IgE) antibodies that target specific proteins in coriander and cilantro, triggering allergic symptoms ranging from mild skin reactions to severe anaphylaxis. The Coriander/Cilantro (f317) IgE test is the most important test for diagnosis because it specifically measures the antibodies responsible for allergic reactions.

Question 2

What causes coriander/cilantro allergy?

Accepted Answer

Coriander/cilantro allergy is caused by an overreaction of the immune system to specific proteins found in the coriander plant (seeds) and cilantro (leaves). When you consume or come into contact with these herbs, your immune system mistakenly identifies certain proteins as harmful invaders and produces immunoglobulin E (IgE) antibodies to attack them. This immune response triggers the release of histamine and other chemicals that cause allergic symptoms, which can range from mild itching and hives to severe reactions like difficulty breathing or anaphylaxis.

Question 3

What is the best test for coriander/cilantro allergy?

Accepted Answer

The Coriander/Cilantro (f317) IgE test is the most important test for coriander/cilantro allergy because it specifically measures the IgE antibodies your body produces in response to coriander and cilantro proteins. This blood test provides definitive confirmation that your symptoms are caused by an allergic reaction rather than food intolerance or other digestive issues. The test results are reported in classes or numerical values, with higher levels indicating greater allergic sensitization. Your healthcare provider can use these results to confirm the diagnosis, assess the severity of your allergy, and develop an appropriate management plan including dietary restrictions and emergency preparedness protocols.

Question 4

When should I get tested for coriander/cilantro allergy?

Accepted Answer

You should get tested if you experience symptoms like itching, hives, swelling of the lips or tongue, difficulty breathing, or stomach upset after eating foods containing coriander or cilantro. Testing is also important if you have a history of reactions to other herbs or spices in the same family (such as parsley, caraway, or fennel), as cross-reactivity is common. You should seek testing before the allergy worsens or if you have experienced increasingly severe reactions over time. Early diagnosis helps you avoid these ingredients safely and prepare for potential accidental exposures with proper emergency medications.

Question 5

What are the symptoms of coriander/cilantro allergy?

Accepted Answer

Symptoms of coriander/cilantro allergy typically appear within minutes to a few hours after exposure and can affect multiple body systems. Common symptoms include itching or tingling in the mouth, hives or skin rash, swelling of the lips, tongue, or throat, stomach cramps, nausea, vomiting, or diarrhea. More severe reactions can include difficulty breathing, wheezing, rapid pulse, dizziness, or a drop in blood pressure leading to anaphylaxis. Some people may also experience contact dermatitis from handling fresh cilantro, resulting in red, itchy skin where the herb touched.

Question 6

Who is at risk for coriander/cilantro allergy?

Accepted Answer

People with existing food allergies, particularly to other herbs and spices in the Apiaceae family (such as parsley, celery, caraway, fennel, or anise), are at higher risk for coriander/cilantro allergy due to cross-reactivity. Individuals with seasonal allergies, especially mugwort or birch pollen allergy, may also develop reactions to cilantro through oral allergy syndrome. Those with a family history of food allergies or other allergic conditions like asthma, eczema, or hay fever have an increased likelihood of developing this allergy. The allergy can develop at any age, even if you have previously consumed these herbs without problems.

Question 7

What happens if coriander/cilantro allergy is left untreated?

Accepted Answer

If coriander/cilantro allergy is left undiagnosed and untreated, continued exposure can lead to increasingly severe allergic reactions over time. Repeated exposure may cause the immune system to become more sensitized, potentially progressing from mild symptoms to life-threatening anaphylaxis. Without proper diagnosis, you may unknowingly consume these herbs in processed foods, restaurant meals, or ethnic cuisines where they are common ingredients, putting yourself at risk for unexpected reactions. Unmanaged allergies can also lead to chronic inflammation, digestive issues, and reduced quality of life due to constant worry about accidental exposure.

Question 8

Can coriander/cilantro allergy be diagnosed with a blood test?

Accepted Answer

Yes, coriander/cilantro allergy can be definitively diagnosed with a blood test that measures specific IgE antibodies against coriander and cilantro proteins. The Coriander/Cilantro (f317) IgE test is a simple blood draw that detects the presence and level of these antibodies in your bloodstream. Blood testing is often preferred over skin prick tests because it is safer for people with severe allergies, does not require stopping antihistamine medications, and provides quantifiable results that can help assess the severity of sensitization. The blood test can distinguish true allergic reactions from other food sensitivities or intolerances that do not involve IgE antibodies.

Question 9

How is coriander/cilantro allergy treated?

Accepted Answer

The primary treatment for coriander/cilantro allergy is complete avoidance of both the seeds (coriander) and leaves (cilantro) in all forms, including fresh, dried, and as ingredients in spice blends or prepared foods. For mild allergic reactions, over-the-counter antihistamines can help relieve symptoms like itching and hives. If you have a history of severe reactions, your doctor will prescribe an epinephrine auto-injector (EpiPen) to carry at all times for emergency use in case of anaphylaxis. You should also wear medical alert identification, carefully read food labels, and inform restaurants about your allergy when dining out, as coriander and cilantro are common in many cuisines including Mexican, Indian, Thai, and Middle Eastern foods.

Question 10

How can I prevent coriander/cilantro allergy reactions?

Accepted Answer

Prevention focuses on strict avoidance of coriander and cilantro in all forms. Always read ingredient labels on packaged foods, as these herbs may be listed as coriander, cilantro, Chinese parsley, or simply as spices. When dining out, clearly communicate your allergy to restaurant staff and ask about ingredients in dishes, especially at Mexican, Indian, Thai, Vietnamese, and Middle Eastern restaurants where these herbs are commonly used. Be cautious with curry powders, garam masala, pickling spices, and other spice blends that often contain coriander. Consider wearing a medical alert bracelet and always carry your prescribed epinephrine auto-injector if you have severe allergies. Watch for cross-contamination in your kitchen by keeping separate utensils and cutting boards if others in your household use these herbs.

Question 11

What natural remedies help with coriander/cilantro allergy symptoms?

Accepted Answer

While there are no natural remedies that cure coriander/cilantro allergy, some approaches may help manage mild symptoms after accidental exposure. Quercetin, a natural antihistamine found in onions, apples, and green tea, may help reduce histamine release and inflammation when taken regularly. Probiotics can support gut health and immune system balance, potentially reducing the severity of allergic responses over time. Vitamin C has natural antihistamine properties and may help minimize mild allergic symptoms. However, these natural approaches should never replace prescribed medications like antihistamines or epinephrine for managing allergic reactions. Always consult with your healthcare provider before using supplements, and remember that complete avoidance of the allergen is the only reliable way to prevent reactions.
