Thunderstorm asthma risk in geographic regions with temperate grasses is strongly correlated with the trifecta of ryegrass pollen (RGP) sensitization (serum RGP-specific IgE), seasonal allergic rhinitis (SAR) and exposure to a thunderstorm during the pollen season.[1,2] Perennial ryegrass (Lolium perenne) is a wind-pollinated pasture grass prevalent in southeastern Australia, North America and Southern Europe.
