Pollen Allergen

Amaranthaceae and Chenopodiaceae families

These weeds are grouped together since the pollen are very similar in appearance and the antigens cross-react. They are important in causing allergic reactions but are not found in very high numbers in air samples at most locations. The pollen season is from May to November and they can be found as early as April in the warmer climates. Their significance in pollinosis is considered to be rather small.
