Allergy to natural grass is a common pathology that makes the sufferer uncomfortable. Simple contact with the material will cause the appearance of symptoms which can range from conjunctivitis to a rash. Throughout the article we will explain the causes and treatment of this condition.

Why does a grass allergy occur?

Allergies, also known as hypersensitivity, are reactions that the body develops to certain substances called allergens. When the body comes into contact with an allergen, the immune system recognizes it as foreign, secretes substances (histamine) and generates symptoms.

Pollen is one of the most frequent allergens and all plants produce it during the spring as part of their natural process. That pollen produced by the flowers is transported by insects in small quantities, however, the wind is capable of carrying large quantities.

When being transported by the wind, it is deposited on the grass, so this plant can harbor a large number of different allergens. Grass allergy appears when a person who has developed hypersensitivity comes into contact with this pollen, either from the lawn itself or from some other plant.

According to the American Academy of Allergy, Asthma and Immunology, many types of grass can cause allergies. However, the most frequent are the following:

  • Bay.
  • Bermuda.
  • Canary.
  • Kentucky Blue.
