There are currently 11 identified ragweed allergens, with Amb a 1 and 11 recognized as the primary triggers. Epidemiological data indicate higher rates of sensitization in North America and Europe, with a growing trend observed in China. Ragweed-induced type I hypersensitivity typically presents as seasonal allergic rhinitis, conjunctivitis, and asthma symptoms. Strategies for managing ragweed allergy include allergen avoidance, pharmacotherapy, and allergen immunotherapy (AIT). Biological control using <i>Ophraella communa</i> and <i>Epiblema strenuana</i> effectively limits ragweed proliferation. Accurate allergen identification and personalized treatment can significantly reduce the health burden associated with ragweed.
