Ragweed Pollen

Ragweed Pollen

Ragweed pollen is the primary cause of the recurrent bouts of sneezing, nasal congestion, and itchy eyes known as hay fever in the United States. The coarse annuals depend on the wind for cross-fertilization and since a single plant may produce a billion grains of pollen during a season, many of the grains inadvertently find their way into the noses and throats of humans.
