Pollen allergy

Sufferers react to one or more types of pollen, most often to grass. Typical symptoms are sneezing attacks, runny nose and streaming eyes.

Pollen allergy should be treated by a customized therapy.

Ambrosia pollen can trigger severe allergic reactions. Spread of this feared weed was successfully halted years ago.

Severe allergic symptoms are primarily triggered by the tall grasses growing in pastures, various cereal species such as maize and rye. 

The pollen season of birches is starting around 2-3 weeks earlier than 20 years ago. The grass pollen season is starting around 10 days earlier: impact of the climate change?

High concentration of air pollutants alter the allergen content of pollen and enhance their impact.

A non-native ornamental alder species (Alnus spaethii) causes hay fever  as early as Christmas.
