With a ragweed allergy, the immune system recognizes the pollen as a dangerous substance and combats this perceived threat by releasing inflammatory chemicals that fight against the pollen, despite it being harmless. Ragweed pollen is characterized by its high potential to cause type I allergic reactions, also known as an immediate reaction involving immunoglobulin E (IgE) mediated release of antibodies 1. However, the exact timing and peak of ragweed pollen release vary from year to year depending on weather conditions like wind, rainfall, and temperatures.
