Cultivated Oat Grass
Cultivated oat grass (Avena sativa) is a common cereal crop grown widely across temperate regions. In addition to its use in agriculture, it is a known airborne allergen. During its pollination season, oat grass releases pollen that can become airborne and inhaled, potentially triggering allergic reactions in sensitive individuals. Reactions may include symptoms such as sneezing, nasal congestion, itchy eyes, and respiratory irritation. It is one of many grasses whose pollen can contribute to seasonal allergic rhinitis, also known as hay fever.
Description
Yes, many grass pollens share similar proteins, and cross-reactivity is common among species such as timothy grass, ryegrass, and cultivated oat grass. This can make it difficult to pinpoint the exact source of symptoms without specific testing.
Oat grass usually pollinates from late spring to early summer, although this can vary depending on the climate and region.
