In allergy terms, what is the distinction among pollen, grass, ragweed, and trees?
Last night’s late local news ran a story on allergy triggers. According to a graphic, 82% of people have pollen allergies, 68% have grass allergies, 55% have grass allergies, and 48% have tree allergies. (I can’t remember the exact numbers, but it was something like that.)
The thing I couldn’t understand is the distinction between pollen and the others on the list. I thought pollen was emitted by grass, ragweed, trees, and other plants.
Please set me straight or freely criticize the reporters.
