Which conifers can cause pollinosis?

Cypress is a conifer widely distributed in Mediterranean regions, known for its ornamental properties and longevity. However, it is also known to be a major source of pollinosis, an allergic reaction caused by pollen.

Cypress pollinosis occurs mainly in spring, the tree’s pollination season. Cypress pollen is particularly small and light, enabling it to disperse easily in the air and reach the human respiratory tract.

Symptoms of cypress pollinosis include sneezing, itchy eyes, nasal congestion and sometimes asthma attacks in sensitive individuals. It’s important for allergy sufferers to be aware of cypress pollen season and to take preventative measures, including avoiding outdoor activities during pollen peaks and using air filters to reduce exposure to pollen indoors.
