The mugwort (Artemisia) is in full bloom. This common herbaceous plant is often considered as a weed and blooms generally from end July till end August. Its pollen may induce problems to allergy sufferers. During the summer months, the air contains high densities of allergenic fungal spores from the genera Alternaria and Cladosporium. These molds typically grow on decaying herbaceous plants.

 

Good to know:

  • Indiviual sensitivity may vary a lot. It is reported in literature that from 5 mugwort pollen grains per m³, most sufferers sensitized to this type of pollen will experience allergy symptoms. For Alternaria and Cladosporium, 500 and 3000 spores per m³ are respectively enough to induce respiratory problems for sensitized persons.

 

Several useful recommendations for allergic people:

  • Rigorously follow the treatment prescribed by your physician.
  • Avoid outdoor efforts and activities (sports, physical efforts). Indoor activities are a better option.
  • Limit the aeration of your home during the pollen season, preferably during or after the rain. Keep the windows closed when you travel by car.
