Allergens are substances that leads to allergic reaction in the body. Allergic rhinitis is a condition characterised with symptoms of allergic response to specific allergens. Generally, the symptoms flare up with the change of seasons. Around 30% of the world population is said to have allergic rhinitis.
Our nasal cavity has various structures that block the passage of foreign matter into the nose. The mucous membrane produces sticky mucus which prevents entry of small particles through the cavity to lungs.

Seasonal allergic rhinitis occurs during the change of seasons from spring, late summer and fall. These are caused due to pollen or mould spores in the air. It is easily carried through the air and inhaled.
Perennial allergic rhinitis is caused due to allergens such as dust mites, pet dander, or mould. The symptoms may last longer up to a year.
The most common form of allergy is hay fever. They occur seasonally and aggravates when its affected by pollen.

When body comes in contact with an allergen, it will release histamine. Histamine is a biologically active substance found the blood that defends body from allergens or allergic response. These may cause symptoms like running nose, sneezing, and itching in the eyes.

Rhinitis is a common disease of respiratory system. In ayurveda, it is explained under Nasaghata rogas. As per ayurvedic science allergic rhinitis can be compared to Vata-kaphaja Pratishyaya. Ama (undigested food) when generated in the body afflicts the Rasa and Rakta dhatu and leads to the disease Pratishyaya. Virudhha ahara (incompatible food) also leads to allergic symptoms. Clinical features include Tanu nasa srava (running nose), Shirashoola (headache) and Kshavathu (sneezing).
