What is hay fever?
Hay fever is an allergy to pollen from trees, grasses or herbs. The immune system reacts excessively to substances that are actually harmless.
Typical symptoms are:

Many people mainly experience symptoms in spring, when there is a high level of pollen in the air. Are you currently experiencing similar symptoms? Find suitable medication with the Medi-Finder.
