Pollen is most common causes of allergies. These are very fine powders produced by flowers, trees, grass and weeds. In people with pollen allergies, immune system mistakes harmless pollen as dangerous and produces chemicals to fight against pollen. This is called as allergic reaction to the specific type of pollen which acts as allergen. This reaction leads to some symptoms such as:
