What is Ragweed?

A primary culprit of fall allergy symptoms is Ragweed. A single ragweed plant can produce millions of pollen grans and because these pollen grains are very light weight, they travel very easily through the air. Allergy symptoms, such as itchy, red, watery eyes, runny nose, and sneezing occur when your body’s immune system treats the allergen as a foreign invader and histamine is released into the bloodstream. Proper diagnosis is the first step to manage allergy symptoms.
