What is Sweet Vernal Grass? (Environmental Toxin - Flowers, Shrubs & Trees)

What is Sweet Vernal Grass and where is it found?

Sweet vernal grass (Anthoxanthum odoratum) is a perennial grass with a sweet, vanilla scent from coumarin. Native to Europe and Asia, it’s now also found in North America, Australia, and New Zealand, growing in meadows, pastures, and roadsides. It flowers early in spring, releasing pollen.

Why do I have an inflammatory reaction to Sweet Vernal Grass?

An inflammatory reaction to sweet vernal grass is usually due to its pollen, which can trigger symptoms like sneezing, itchy eyes, runny nose, and respiratory discomfort. Since sweet vernal grass is one of the first grasses to release pollen in spring, it can be an early-season allergen for sensitive individuals.

What can I do about it?

Avoid areas with sweet vernal grass, especially in early spring when it pollinates. Rinse your nasal passages after exposure to clear out pollen. Reduce indoor pollen by keeping windows shut, particularly on windy days.
