Russian thistle, also known as tumbleweed, is a plant whose pollen can cause seasonal allergic reactions. Its pollen is a common allergen, especially in dry areas. During the flowering season, the lightweight pollen can travel long distances, affecting many people. Symptoms are typical of hay fever and include sneezing, itchy eyes, and a runny nose.
Testing for Russian thistle allergy is advisable if you experience hay fever symptoms during its pollen season, particularly if you live in or travel to arid regions where this plant is prevalent.
Russian thistle becomes an allergen when its pollen enters the air. The immune system of allergic individuals mistakenly sees this pollen as a threat, causing an allergic reaction.
To minimize symptoms, check pollen forecasts and limit outdoor activities on high-pollen days. Keeping windows closed and using air filters can help reduce exposure to Russian thistle pollen.
