What is Pollen?

Pollen, a fine to coarse powdery substance, is created by certain plants as part of their reproduction process. It can appear from trees in the spring, grasses in the summer, and weeds in the fall.

Pollen in the air can trigger sneezing, congestion, watery eyes, and other cold-like symptoms. Seasonal allergies – also known as allergic rhinitis or hay fever – may affect nearly one in six Americans.
