The risk of allergies is not the same depending on the region. In the southwest, it comes from a mixture of cypress, alder and ash pollen. On the Mediterranean coast, the risk of allergies due to cypress pollen remains high. Among Grand Est, elder pollen is the most important. Elsewhere in France, the risk of allergy is low to moderate, the RNSA suggests, because of alder or even ash pollen.
