Simply put, Cromolyn is a medicine that helps reduce your allergy symptoms, such as sneezing, itchy nose , stuffy nose, and runny nose . It belongs to a class of drugs called Mast Cell Stabilizers.

Imagine, inside our bodies there are little soldier-like cells called 'mast cells'.

Those chemicals are what cause our nose to get blocked, itchy, and sneeze.

Then the swelling and inflammation in the nose decreases and you can breathe easier. It comes as a nasal spray. You may have seen it under the brand name `Nasalcrom`.
