Many people are allergic to windborne pollen from grasses, weeds and trees. This pollen can blow into your nose and eyes, triggering asthma and allergies.
Problem pollen usually comes from imported grasses, weeds and trees, which are wind pollinated.
Australian native plants are usually not the culprit, although there are exceptions, such as cypress pine.
Allergies are not usually triggered by highly flowered plants as they produce less pollen (which is transported by bees) than wind pollinated plants.
‘Thunderstorm asthma’ is a potent mix of pollens, weather conditions and rain that can trigger severe asthma symptoms.
