pollen is the word used to describe the male fertilizing elements given off into the air by flowering plants. Inside of the pollen grains there are proteins that can cause allergic reactions in genetically predisposed people. The pollens that are most often responsible for causing allergic rhinitis come from weeds, trees and grasses.
