What is Olive Pollen?
Olive pollen comes from olive trees, which are known for producing small, yellow-green flowers. Olive trees release pollen into the air during their pollination season.

This pollen can cause allergic reactions in some people. Olive pollen allergies can be quite bothersome, especially in areas where olive trees grow in large numbers.
Like alder pollen and birch trees, olive trees release pollen that can trigger seasonal allergies.
Many people who are allergic to pollen from these trees experience similar symptoms during allergy season.
Symptoms of an Olive Allergy
If you are allergic to olive pollen, you might notice symptoms like:
- Itchy or watery eyes
- Runny or stuffy nose
- Sneezing
- Itchy throat
- Wheezing or trouble breathing in more severe cases
- Fatigue or feeling tired from allergy symptoms
Where is Olive Pollen Found?
Olive trees are commonly found in warm, Mediterranean climates. They grow in countries like Spain, Italy, Greece, and parts of North Africa.
Olive pollen can be a major problem in cities like Madrid, Rome, Athens, and Seville, where olive trees are everywhere.
Even though olive trees are mostly found in these warm areas, people in other parts of Europe might also be exposed to olive pollen if the trees are grown there.
When is Olive Pollen Season?
Olive pollen season usually starts in the spring and can last through the summer. In the Mediterranean, olive pollen is most common from late April to June.
However, the exact timing may depend on the weather and location. The pollen count tends to be highest during warm, dry, and windy days when the pollen is easily spread through the air.
Treating an Olive Pollen Allergy
If you are allergic to olive pollen, there are several ways to manage your symptoms:
- Antihistamines: These medicines can help reduce sneezing, runny nose, and itchy eyes.
- Nasal sprays: Steroid nasal sprays can help with congestion and inflammation in the nose.
- Eye drops: These can soothe itchy, watery eyes.
- Allergy shots: Immunotherapy can be used for severe allergies to build up a tolerance to olive pollen over time.
- Avoidance: Try to stay indoors on high pollen days, especially when it’s windy. Keeping windows closed can also help limit exposure to pollen.
