Cedar is on its way!
Much of the U.S. is either well past the first frost of the season, or about enter this doorway that heralds relief from Ragweed symptoms. But as you cross the threshold, beware. Cedar is on it’s way!
Two of the most common Cedars that cause allergies in the U.S., Mountain Cedar and Eastern Redcedar (also called Eastern Red Cedar), are actually Junipers. Cedar/Juniper is the most common winter pollen allergen in the U.S.
Cedar usually pollinates from November through March in the U.S. But in some areas or seasons it can start pollinating as early as October, and it can continue as late as May.
Cedar is quite a loner. Sometimes a person is allergic to multiple trees as well as Cedar. But we often find that a patient will be allergic to most of the trees we test for — except Cedar. Other times we will see a Cedar allergy without allergy to any other tree. Of course, this can happen with other trees too. But it happens most frequently with Cedar.
So if you are one of those who sniffle and sneeze during Cedar season, get ready. Stock up on your allergy medicine and close the all the windows and doors. Because Cedar is coming!
