Which plants cause pollen allergies?

Which plants cause pollen allergies?

Pollen is a very fine powder produced by plants, which is used to fertilise other plants from the same species. As pollen cannot move on its own; animals, wind and sometimes water, help move the pollen across between plants to aid in the process of pollination. Plants such as pasture grasses, weeds and exotic trees, rely on the wind to spread vast quantities of their pollen grain and it’s these types of plants that can cause pollen allergies (also known as Hayfever or Allergic Rhinitis) in people.

What are the different types of plants that cause pollen allergies?

In Australia, there are many different grasses, weeds and trees that can trigger pollen allergies, but some plants are more allergenic then others. Most allergic reactions in Australia are triggered by airborne pollen from plants in the northern hemisphere and common examples of these can be found below.

Weed Pollen Allergy:
Pellitory/asthma weed
Parthenium weed

Tree Pollen Allergy:
Australian pine/she oak
Paper-bark tea tree

Grass Pollen Allergy:
Bermuda/couch grass
Cocksfoot/orchard grass

What are the signs of a pollen allergy?

For those who suffer from pollen allergies, some of the most common symptoms include a runny or stuffy nose, itchy nose, itchy and watery eyes, itchy skin or sneezing. In patients with moderate or severe pollen allergy, their symptoms can often lead to further complications including sleep problems, daytime tiredness, headaches and difficulty concentrating.

How is a pollen allergy diagnosed?

A healthcare professional will take a thorough medical history, physical exam and review your symptoms to diagnose your condition. From this, they will be able to advise you if you have a pollen allergy. Questions will include when your symptoms occur, how often they happen and what seems to trigger them. These answers can then determine which allergen is causing the symptoms and provide more targeted options to treat them. In addition, there are skin allergy tests which can be taken to diagnose which allergen is causing your symptoms.

What is the treatment for a pollen allergy?

For those diagnosed as a mild sufferer of pollen allergies, a doctor or pharmacist may recommend lifestyle management to help prevent allergy symptoms. However, for those with more severe symptoms, a pollen allergy treatment such as Telfast may be recommended to control the allergen’s effects. Telfast has a range of different strengths and formats to relieve hayfever allergy symptoms, including those related to pollen.
