Grass Pollen

sweetvernalGrass pollen is the predominant pollen in the air during the summer here in Idaho. Allergy to this pollen can cause sneezing, runny nose and itchy eyes, as well as asthma attacks in some people.
Grasses can be divided into two major classes: northern and southern grasses. Northern grasses are common in colder climates, and include timothy, rye, orchard, sweet vernal, red top and blue grasses. Southern grasses are present in warmer climates, with Bermuda grass being the major grass in this category. Most people with significant grass allergy are allergic to most, if not all grasses, on allergy testing, because grass pollens have very similar proteins.
