Platanus × Acerifolia Antigen

Wind-pollinated tree pollens, such as those from poplar, willow, paulownia, juniper, pine, ginkgo, oak, eucalyptus, paulownia (again), and casuarina, are major airborne allergens. These trees produce large quantities of pollen over extended periods. The pollen grains are small in diameter, light in weight, and buoyant, allowing them to disperse over wide areas and long distances.

From mid-March to April each year, most sensitizations are caused by cypress pollen. Cypress trees are evergreen, and their flowering in spring often goes unnoticed, yet they release pollen into the air. After the “cypress pollen season” ends, pollens from birch, ash, toona, and paulownia trees follow, all of which can trigger allergic reactions. The incidence of such pollen allergies typically increases in May.
