    Allergies to Oak

    Future Studies

    San Antonio area oak trees release their pollen in late winter and spring, with the greatest amount of pollen released in the early morning. Since oak trees do not produce flowers, they do not rely on bees and other insects to spread their pollen. Instead, oak trees will release a large amount of the fine, yellow, dust-like pollen into the air to ensure successful pollination. 

    People who are allergic to oak pollen will typically experience the following allergic symptoms: sneezing, runny or stuffy nose, coughing, postnasal drip, itchy nose and throat, dark circles under the eyes, and swollen, watery and itchy eyes. Some people have more severe reactions to allergens and even have asthma attacks.
