Seasonal allergic rhinitis or hay fever as it is often called is a common problem that affects both adults and children.

Simply put, seasonal allergic rhinitis is your body’s reaction to a perceived threat: allergens. Allergens
are the things you are allergic to, and are usually harmless substances that can cause problems in some people. Seasonal
allergens (such as pollen) are often microscopic airborne particles that are inhaled. When your body’s immune system senses
allergens and feels the body is being threatened, it fights back. The immune system will then release histamine and
