Taro Root Allergies: Here’s What You Need to Know

Taro root is a starchy vegetable that is enjoyed in many different cuisines around the world. It has a nutty taste and creamy texture and can be cooked in various ways, including boiling, baking, frying, or mashing. It is a great source of fiber, potassium, vitamin C, and antioxidants, which all promote good health. However, it can trigger allergies, leading to unpleasant and even dangerous symptoms for some people.

In this article, we will explain what taro root allergies are, what causes them, how they are diagnosed and treated, and how to avoid them. It’s important to note that if you are allergic to taro root, you should avoid consuming it to prevent an allergic reaction.


Taro root allergies are a type of food allergy where your immune system mistakes taro root as harmful and produces antibodies to fight it. These antibodies cause inflammation and allergy symptoms by releasing histamine and other chemicals. Although rare, these allergies can affect anyone at any age, and the severity depends on factors like how much taro root is eaten, a person’s sensitivity, and if they have other allergies or asthma.


Symptoms of Taro Root Allergies

Symptoms can vary from person to person but typically appear within minutes to hours after eating taro root or foods containing it. Common symptoms include:


Mild Symptoms

      • Itchy or swollen mouth, tongue, lips, or throat
      • Hives, rashes, or red skin
      • Sneezing, runny nose, or congestion
    • Watery, itchy, or red eyes
    • Nausea, vomiting, or diarrhea
    • Abdominal pain or cramps

Causes of Root Allergies

Taro root allergies can be linked to a protein called thaumatin-like protein (TLP), which is present in the root and some other plants. TLP helps protect plants from fungi and insects, but some immune systems treat it as an invader, producing antibodies that react with TLP when ingested or inhaled.

Certain factors can increase the risk of developing allergies, such as a family history of allergies, asthma, eczema, or hay fever, having other food allergies, consuming raw or undercooked taro root, and being exposed to dust or vapors during its preparation.


Diagnosis of Taro Root Allergy

If you suspect a taro root allergy, consult your doctor for a proper diagnosis. Your doctor will inquire about your medical history, symptoms, and exposure to taro root and may perform tests like:

  • Dermal Sensitivity Test: A tiny amount of extract from the suspected root is applied to your skin, followed by a gentle needle prick. An allergic reaction will result in a red bump within 15 to 20 minutes.
  • Blood test: Measures specific antibodies in your blood, indicating an allergy.
  • Oral challenge test: Used when other tests are inconclusive, involving consuming a small amount of the suspected allergen to check for reactions.


Treatment of Taro Root Allergies

If you are allergic to taro root, avoiding foods containing it is important. Always check food labels carefully and ask about ingredients when dining out. If you experience mild symptoms, taking antihistamines can help by blocking the effects of histamine, which is the chemical responsible for causing allergic reactions. However, if you experience severe symptoms or anaphylactic shock, it’s crucial to seek emergency treatment with epinephrine.

Epinephrine can reverse the effects of histamine and restore breathing, blood pressure, and heartbeat. If you have severe symptoms, use an epinephrine auto-injector immediately and seek medical attention immediately.

Prevention of Taro Root Allergies

While there’s no cure, you can prevent taro root allergies by avoiding taro root and minimizing exposure to its dust or vapors by:

  • Wearing gloves, masks, and goggles when handling or cooking taro root.
  • Thoroughly cleaning hands, utensils, and surfaces after using taro root.
  • Cooking it thoroughly reduces allergenicity.
  • Storing taro root in a sealed container away from other foods.
  • Informing family, friends, and healthcare providers about your taro root allergy.



Taro root is a nutritious and versatile vegetable but can trigger allergies in some. Although rare, these allergies can be severe or life-threatening. If you have a taro root allergy, avoid it and its products, carry an epinephrine auto-injector, and consult a doctor for proper diagnosis and treatment.
