PollensPollens are the microscopic, ball-shaped granules of flowering plants needed for plant fertilization. They are invisible to the naked eye.

Trees, grasses and weeds have small, light, dry pollens that are well-suited for dissemination by wind currents. These are the pollens that trigger allergy symptoms.

Pollens from plants with bright flowers, such as roses, usually do not trigger allergies. These large, waxy pollens are carried from plant to plant by bees and other insects.

The beginning and ending times of tree, grass and weed pollen seasons are very similar from year to year in the same location. Intensity differs every year based on the previous year's weather, current weather, and other environmental factors. This is why some patients report different intensity of their allergy symptoms with different seasons.

In Kuwait, the peak seasons for pollens are during spring & fall seasons.

The most important allergenic pollens are:

  • The Spring season Bermuda Grass, Salsola baryosma & Altenaria molds.
  • The Fall season Salsola baryosma
  • The winter Season Molds (such as: Aspergillus, Penicillium, Cladosporium, etc..)
  • The Summer Season Low grade pollens mainly from the Salsola plant.
