Sagebrush (Artemisia vulgaris), also known as mugwart, is native to temperate Europe, Asia, northern Africa and Alaska and is naturalized in North America. According to Montana Fish Wildlife and Parks, there are over 11 different species of Sagebrush (Artemisia) in Montana, and 17 different species in the US. It’s one of the many weeds that produce pollen, and a very common allergen.
Basic Information about Sagebrush
Allergy type: Non-food allergy, weed-pollen allergy
Habitat: Sagebrush is naturalized to North American. It can be found in disturbed areas of upland prairies, particularly along the margins near developed areas. Other habitats include weedy meadows, cropland, abandoned fields, vacant lots, fence rows, roadsides, gravelly areas along railroads, gardens and lawns, construction sites, and waste areas. This plant thrives in a variety of disturbed sunny sites, especially where the topsoil has been exposed. It has can inhibit the growth and development of neighboring plants, so some consider it a noxious weed, though it is not specifically listed as such in Montana.
Allergy season: late summer to early fall
Allergic reactions: mild to severe, depending on the pollen count and the body’s sensitivity
Sagebrush Allergy Causes
Although the allergy is usually rampant during the late summer and early fall, there is also a small chance of getting allergy symptoms during other seasons. More pollen is carried into the air during hot and windy days, which is why most allergic reactions occur before winter.
Weed pollen, in general, is regional and seasonal, according to the National Institute of Environmental Health Sciences. Weed pollen count is affected by several factors such as time of the day, weather and season.

Tips For Preventing Sagebrush Allergy Symptoms
- Stay indoors from 5:00 AM to 10:00 AM, as this is when the pollen count is highest. Leave outdoor activities until 5:00 PM, or after a heavy rain. You can get a pollen count reports from other websites, though they are not accurate to the hour.
- If you can, remove Sagebrush from your surroundings, and wear a mask when doing so. If you can afford it, consider hiring someone else to do the removal.
- Always keep your home and car windows closed. This lessens their exposure to pollen. Avoid window and attic fans as they will draw air from outside of your house, which may be contaminated with pollen.
- Use a dryer for your clothes. If you hang them outside, pollen can attach on your clothes. This will expose you and your house to the allergens.
- Regularly bathe your pets. Pollen could also be attached to them.
- Minimize your alcohol intake. A study from the National Institute of Public Health in Denmark last 2008 found a relation between alcohol and the allergy. Women who drank alcohol every week increased their susceptibility to the allergy by 3%. Alcohol also dehydrates the body, which can make the nasal symptoms worse.
