Ragweed plants are a common allergen. When a person breathes in ragweed pollen, their immune system may react as if it is an illness-causing substance, and they may experience allergy symptoms.
There are 17 types of ragweed that grow in the United States, typically releasing pollen between August and September.
Just one plant can release as many as 1 billion pollen grains, which create future ragweed plants and cause significant seasonal allergies.
