Tree Allergies
Millions of people suffer from tree allergies around the world every year. While there are some trees allergy symptoms during the fall months, spring is normally when tree allergies are at their worst. Trees actually pollinate before other plants and weeds and may start releasing their pollen as early as January in the southern states and as late as June in the northern part of the United States. Tree pollination is critical for the reproduction process and certain tree species such as mountain cedar are known to create havoc in people with allergies and even some who have never had allergy symptoms.
Trees can produce large amounts of pollen which can travel miles away from the original source before causing an allergic reaction. Tree pollen reactions can range from mild to severe with mild symptoms consisting of hives and sinus (runny nose) problems. Severe reactions to tree pollen may be coughing, wheezing, difficulty breathing and hoarseness.
