Plants that Causes Allergy
US Department of Health and Human Services Public Health Service National Institutes of Health found that millions of American are suffering from cough, sneezing, running nose and watery eyes when pollen start flying in the air. During spring season few tiny particles are released from the trees; these tiny particles are known as pollen. Their task is to fertilize other plants but most of the time they do not reach their destination rather they cause irritation in human noses and throats which eventually causes pollen allergy also called hay fever or rose fever. Following are the few worst plants that cause severe form of allergies among masses:
The allergic rhinitis is also known as hay fever. Pollen is found on the plants and trees and it causes the watery eyes, stuffy nose. The fever caused due to pollen grains is known as hay fever because it was discovered in the haying season. AAFA (American Association for Asthma and Allergy) is trying to reduce the plants and trees that cause allergies in the different cities.
Ragweed is found in the fields, at the river banks, roadsides and rural areas. Mild west and the Mississippi River Basin have more than average of Ragweed. The peak time of Ragweed is summer and fall. Dr Filley says that it is the most allergenic plant. It is not very common in the England so the amount of pollen is also less in England. AAFA says that 75% of Americans are allergic to Ragweed.
