From mid-February to the end of March, copious amounts of Arizona’s most allergenic pollen billow out from juniper trees. Junipers are to the Southwest what fir trees are to the Northwest: widespread and represented by several species. While junipers define the landscape on the Colorado Plateau with their glacial growth, half-dead/half-alive appearance and fragrant aroma, they are THE GREATEST trigger of allergic reactions in winter.
Although junipers are found from sea level to 10,000 feet in elevation across the West, they are most abundant in the Coconino National Forest at elevations between 4,500-8,000 feet. They are common on the mesa tops and ridges and often found in association with pinyon and ponderosa pines.
Juniper tree pollen triggers sneezing, wheezing, coughing, itchy and watery eyes, itchy red rashes on the eyelids, nasal congestion, headache and asthma. Approximately 50 percent of children and adults residing in Coconino County are affected. Juniper pollens are unique, in that they can cause allergic reactions in individuals with no other environmental allergy or sensitivity. This high allergenicity has to do with the size and buoyancy of the pollen – very small and very lightweight.
During the blooming season, Juniper trees produce copious amounts of pollen. In fact, pollen production can be so abundant that clouds of pollen can be seen drifting in the air like smoke. The dry, warm climate and high wind velocity of Northern Arizona can effortlessly spread juniper pollen 120 miles. The small size of the pollen is easily conveyed through the mucus membrane of the eyes, nose and mouth. After a few years of moderate exposure, even the least allergic person will develop a reaction to junipers.
Self-care for the allergic reaction includes anti-inflammatory nasal spray, over-the-counter anti-histamines and avoidance. Conventional medical treatments of steroid injection to down-regulate the immune system or under-the skin-injections of tree pollen to desensitize the immune system provide temporary relief only. Both approaches must be repeated to suppress the symptoms.
Advanced Allergy Therapeutics (AAT) is a clinically effective treatment for the elimination of symptoms associated with juniper tree pollen as well as other environmental allergens. AAT is safe, non-invasive and requires no shots, needles or drugs. By combining 21st century science with Traditional Chinese Medicine, AAT offers a highly effective treatment that will provide life-long relief from the symptoms caused by juniper and all other tree pollens.

Wow!! During the last week of February I was visiting friends in Prescott Valley, AZ, and stopped in Flagstaff, AZ, for lunch and had many of the symptoms described here: sneezing, coughing, watery eyes, etc. Thankfully, by the next day I was my usual,happy-go-lucky self. Thanks for the explanation!!

Are there male and female juniper trees or does every tree produce pollen?
Conrad Altmann says
There are male and female trees of Juniperus ashei (Mountain Juniper and the main cause of “Cedar Fever”). The male trees produce copious amounts of pollen and rate very high on the allergen scale, but female trees (the ones that produce cones) have little to no pollen and are considered “allergy fighting”.

Thank you so much for your information. Do you know if the Mint Julep Juniper is male or female? I am trying to figure out the allergen level of this particular type. We live in Colorado and want to line our property with this particular species but don’t want to create a massive allergy issue for us as it will end up being well over 200 feet once fully matured. I would truly appreciate your input. Thank you!

I live in Prescott AZ and have 4 huge beautiful juniper trees. This morning I awoke to major nose running and congestion. I know these trees are very active in February/March but what about October?
