What do ragweed allergies Look Like?

Ragweed causes symptoms like stuffy or runny nose, sneezing, and itchy eyes. It can also trigger asthma flares. People who have ragweed allergies are reacting to its pollen. During ragweed season, one plant can release a billion grains of it into the air.

What is the highest pollen count?

A pollen count is generated by measuring the number of pollen grains in a given volume of air, using a pollen trap. A count of 50 pollen grains or less is considered low, and a count of 1,000 pollen grains or more is considered high.
