Question: What is Cedar Fever?
Answer: The term “cedar fever” usually refers to symptoms caused by Mountain cedar allergy. Symptoms are the same as hay fever, including sneezing, itchy eyes and nose, nasal congestion and a runny nose. With both cedar fever and hay fever, a person will not actually have a fever.

Mountain cedar is a type of juniper tree found mainly in South and Central Texas that pollinates in the winter, from December through March. It is usually the only major pollen present during the wintertime in the areas where it grows. Mountain cedar can release such large amounts of pollen that the trees can appear to be on fire, with large clouds of “smoke” rising from the trees.

Other parts of the United States have related species of cedar, juniper and cypress trees that cause springtime allergies. Because pollen is so similar within this family of trees, a person who is allergic to mountain cedar pollen will also be allergic to pollen from juniper and cypress trees.
