Why is treatment necessary in the first place?

The symptoms of an allergy such as hay fever should not be played down as harmless and potentially troublesome symptoms. There is a real danger that the inflammation which underlies every allergic reaction may extend to the deeper respiratory tract, the bronchial tubes (referred to as “progression”). Thus, the supposedly “harmless” hay fever can develop into bronchial asthma.

This deterioration is observed by doctors in at least 30% of all respiratory allergy sufferers who are not directed to treatment which deals with the cause immediately or at all.
