Green tea allergy: Am I allergic to green tea?

Green tea allergy is an uncommon type of allergy but capable of triggering a dangerous reaction. If an individual starts to experience the undesirable effects after consuming products that contain green tea, it is recommended to stop and consult a doctor.

Most of the symptoms are comparable with other food allergies and brought about by the overreaction of the immune system to the components present in green tea. The body wrongly identifies these components as harmful substances and fights them by releasing IgE antibodies and histamine.

What are the common reactions if I have green tea allergy?


The respiratory tract is commonly affected by different types of food allergies. The sinuses are mainly affected due to the inflammation brought about by histamine.

As the sinus cavity becomes swollen, it holds mucus which leads to elevated pressure in the head. This can result to the following:

  • Sneezing
  • Postnasal drip

  • Congestion
  • Facial sensitivity
  • Sinus headaches

The asthma-like symptoms are also common such as the following:

  • Difficulty breathing
  • Shortness of breath
  • Coughing
  • Wheezing

GI tract

The digestive symptoms manifest within a few minutes or up to an hour after the ingestion of products that include green tea. The common symptoms include the following:

  • Bloating
  • Vomiting
  • Diarrhea
  • Gas
  • Abdominal pain

Skin reactions

An individual with green tea allergy might develop rashes or tingling sensation on the skin. The usual rashes linked with the allergy are eczema and hives.

  • Hives are skin welts that are intensely itchy, elevated and red in appearance. They can manifest in just minutes, vanish and reappear.
  • Eczema is a skin condition in which the skin is highly sensitive. There is tingling in the lips, face, tongue or throat.

Is a severe reaction possible?

Even though rare, green tea can trigger a severe reaction or anaphylaxis. This occurs if an individual ends up with a systemic reaction.

Large amounts of histamine are released all over the body which causes the body to go into a state of shock. Remember that this reaction can be dangerous and immediate medical attention is required.
