Mugwort is at the end of its flowering period. Maximal pollen emission of this allergenic herbaceous plant takes place in the first two weeks of August. Mugwort pollen can cause allergenic reactions.

High densities of allergenic fungal spores of Cladosporium and Alternaria occur in the air during the summer months. For Cladosporium, 3000 spores per m³ of air are enough to induce respiratory problems in sensitized persons; for Alternaria the limit is 500 spores per m³ of air.




* A few useful recommendations for people sensitized to pollen :

-Follow rigorously your treatment

-Avoid outdoor activities

-Do not dry your linen outside

-Wear sun glasses
