Grass Pollen Allergy

Although there are 1,200 North American grass species, only a few are responsible for triggering allergies. Spread by the wind, grass pollen can adhere to the nose, skin, hair, eyes and lungs, triggering an attack. Allergic response can also be caused by simply touching grass.

The ones typical of symptoms are categorized in two classes: northern and southern grasses.

Northern grasses, found in cooler climates include:

  • Rye
  • Orchard grass
  • Timothy
  • Red top
  • Sweet vernal
  • Blue grass

Southern grasses, found in warmer climates include:

  • Bermuda grass
  • Kentucky bluegrass
  • Johnson grass

Grass pollen is often present in late spring and early summer. Watering your lawn often and mowing the grass often, before flowering occurs, helps stop the production of most grass pollens.

Grass allergies can be linked with fruit-pollen syndrome (reacting to tomatoes, peaches and potatoes) from cross-reactivity of the proteins in both fruit and grass. Cooking or processing these fruits can break down the proteins, helping to avoid an allergic reaction.
