Everything in the world has its own good and bad aspects. Spring season brings with it the beauty of trees. Flowers start blooming, and trees start to reproduce and grow more. Apart from the natural beauty, the spring season also brings with it sneezing, itchy nose and watery eyes. The spring is also known for its allergies that give a hard time to people. You can take medicines from the pharmacy to cope up with the allergies, but you can prevent yourself from the allergies if you know what these allergies are.

Pollen Allergies

Tree Pollen

Trees cause pollen allergies as there are some trees that release pollen into the air during spring. The pollens released by the trees are light and dry, so the spring breeze is able to carry them far. Not only trees, but grasses and weeds also release these pollen into the air. They are released by the trees, grasses, and weeds to fertilize other plants, but when it gets into the nose of a person who is allergic, they will feel irritation due to allergies. You can take nasal spray from a pharmacy to protect against pollen allergies. Here are some trees that cause pollen allergies.


Birch is a deciduous tree with hardwood. The tree has thin leaves and belongs to genus Betula in the Betulaceae family of trees which includes alders, hazels, and hornbeams. The season of Birch tree varies from March to May, depending on the weather and other environmental conditions. The trees are wind-pollinated and are considered to be cross-allergenicity in Birch species. It means that if a person has an allergy to one species of Birch, they will react to other Birch species as well.


Ash is a flowering plant from the genus of olive and lilac family of the Oleaceae. The trees in this family are mostly deciduous and have 45 to 65 species of medium and large trees. The trees are moderately allergic and entirely wind-pollinated. The Ash trees can be found across Canada, except in the Rockies.

Maple and Box Alder

Maple trees in Canada can be found almost everywhere. The species of the tree and the potential of causing allergy varies across Canada. Box Elder is the most potent tree of this genus. This tree flowers in April and May depending on the location and environment conditions.


Elms tree differs as some are deciduous, while some are semi-deciduous. The Elms are wind pollinated and are moderately allergenic and cause allergies to only some individuals. Other species of Elms are not considered as allergenic, but they are still significant allergens and can be found across Canada.


Oak trees release a vast number of pollens in the air, compared to all the other plants. The number of pollens can increase deliberately if the Oak trees are abundant. Species of Oak trees can be found in Ontario, Quebec, and British Columbia. Pollen release of the Oak trees depends on the weather and environmental conditions. And only some of the antigens cross-react, or else others have their own unique species of Oak.

Grass Pollen

Like tree pollen, the grass pollen allergy is not caused by a large number of grass species. There are only some grass types that can cause pollen allergy and you get their medications from a local pharmacy. The pollen count in the grass is less than that in the trees, so the symptoms of allergy are not so severe. Ragweeds also cause allergies, but not in spring, as they cause allergies starting from late summer until the winter.

There are thousands of species of grasses, but only a few are said to be allergenic. Some grass species are considered allergenic like Bermuda, Johnson, Kentucky bluegrass, timothy, fescue, and others. Grasses are grouped together as they cannot be easily identified, so the amount of pollen released from grasses is vast. Grass pollens are released into the air when they are mowed. Grass allergies are said to begin in June and July, as they are abundant at those times. In some cases, the pollen release of grasses depends on the weather and environmental conditions. In Western Canada, the grasses bloom in the month of May, earlier than others.

Mold Allergies

Mold is another factor that can cause allergies during spring in Canada. Mold causes allergic reactions, and it can be found both indoor and outdoor. Molds are said to cause worst allergic symptoms as the mildew and yeast releases seeds called spores into the wind, and they are abundant in the air carrying them outside. The spores released by the mold can land on a person’s mouth, nose or throat, and causes symptoms similar to pollen like sneezing, congestion, running nose, or watery eyes. If the spores end up in the lungs it can cause asthma, but you can find the proper medication in a pharmacy..

Outside, the mold can grow on things like rotten vegetation, in soil, in compost, and on grasses or on grains. Only some spores of the mold cause allergies and the two spores that are most common are called Alternaria and Cladosporium. Both mold types can be found indoors and also outdoors. Alternaria spore is found on carpets and window frames inside your house, in soil, and on plants. Cladosporium can be founded indoors mostly on moist surfaces. The Cladosporium spores are the largest contributors in airborne spore counts. People don’t realize that they are allergic to mold than they are allergic to trees and grass. People can take medications from the pharmacy to protect themselves from the symptoms of mold.

You should be aware of such allergies so you can take precautions, and save yourself from the annoying health problems later. You can contact our pharmacy, and you will get every medication and injection so that allergies don’t ruin your spring season in Edmonton.
