Ragweed is a common plant that produces pollen, which is a major trigger for seasonal allergies, especially in late summer and early fall. The pollen is lightweight and can travel long distances in the air, making it easy for people to inhale it. Symptoms of ragweed allergy include sneezing, runny nose, itchy eyes, and congestion. People who are allergic to ragweed may find relief through various treatments, such as over-the-counter antihistamines or nasal sprays. Avoiding outdoor activities during peak pollen times and keeping windows closed can also help reduce exposure. Understanding ragweed and its effects is essential for managing allergies.
