Can You Be Allergic to Tea?

Curated by Claudia Shannon / Research Scientist / ishonest

What are the symptoms of a tea allergy?

Like all allergies, tea allergies create an immune response. This occurs when your body mistakenly perceives a substance as dangerous and tries to fight it off by producing antibodies. When triggered, these antibodies cause specific symptoms to occur.

If you have an allergy to tea, your symptoms may include:

  • hives
  • tingling or itching sensation in the mouth
  • swelling of the lips, throat, tongue, or face
  • anaphylaxis

The symptoms of tea intolerance or sensitivity differ somewhat from those of tea allergy. If you have an intolerance or sensitivity to tea, your symptoms may include:

  • nausea and vomiting
  • diarrhea
  • stomach cramps or pain
  • heartburn
  • bloating
  • feelings of irritability

Are there different types of tea allergies?

Teas are categorized as either herbal or nonherbal. You may be allergic or sensitive to components found in either or both types.

If you have an allergy to any component found in tea, you should avoid it completely. If you have a sensitivity to these compounds, you may be able to tolerate them in small amounts, particularly if your tea is only lightly brewed.

Nonherbal tea

Nonherbal teas — which include black, green, oolong, and white teas — contain varying amounts of the same components. It’s these components that cause allergic reactions or sensitivity in some people.

Components of nonherbal tea that can spark an allergic reaction include:

  • caffeine
  • tannins
  • theanine

If you’re allergic to caffeine, avoid black tea.

One 2016 study found black tea contains the highest caffeine content of all nonherbal teas. Green tea was found to contain the most tannin, and both white and green tea contained more theanine than black tea.

Herbal tea

Herbal teas are made from the roots, leaves, stems, and flowers of an almost uncountable number of botanicals.

  • daisies
  • marigolds

Echinacea is another botanical in the Asteraceae family that’s used to make tea. It may also cause allergic reactions in some people.

Malvaceae family

Hibiscus is a member of the Malvaceae family and may cause allergic reactions in people who are allergic to other plants in this family, such as hollyhocks.

Hibiscus also contains tannins and may cause a reaction to people with a tannin allergy.

For those people who find themselves living with a tea allergy, there are options available.

Try a different tea

There’s a dizzying array of both herbal and nonherbal teas to choose from. Chances are, if you’re allergic to one kind of tea, you’ll be able to enjoy another.

Try switching from herbal to nonherbal tea or vice versa. You may also swap out black tea for green, or you may try white tea if caffeine is a concern.

Adjust the steeping time

The length of time you brew any cup of tea will affect the quantity of allergens it contains.

If you have only a mild sensitivity to tea elements such as tannins, a light dunk instead of a long steep may be all you need in order to enjoy your favorite type.

Pick a different drink

Unfortunately, some people may not be able to drink tea at all based on their allergies. If this is the case, there are still ways to get the benefits of tea from other beverages.

Many herbal teas contain beneficial ingredients, like antioxidants. If you’re unable to tolerate most kinds of tea, you can also opt for drinks such as pomegranate or tomato juice.

On a hot day, ice water with lemon, lime, or cucumber slices can easily be swapped in for iced tea.
