Allergic Rhinitis, also known as hay fever, is a type of inflammation in the nose which occurs when the immune system overreacts to allergens in the air. Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. The fluid from the nose is usually clear. Symptom onset is often within minutes following exposure and they can affect sleep, the ability to work, and the ability to concentrate. Those whose symptoms are due to pollen typically develop symptoms during specific times of the year. Many people with allergic rhinitis also have asthma, allergic conjunctivitis, or atopic dermatitis.

Allergic rhinitis is typically triggered by environmental allergens such as pollen, pet hair, dust, or mold. Inherited genetics and environmental exposures contribute to the development of allergies. The symptoms of allergies resemble those of the common cold; however, they often last for more than two weeks and typically do not include a fever.

Allergic rhinitis is most common between the ages of twenty and forty.

Homeopathy is best placed to treat all sorts of allergies or allergic disorders. The reason for this is that it does not try to treat the symptoms of the allergies. Instead, it works to root out the cause of these allergies. The root cause in allergies happens to be a hyperactivity of the immune system. This hyperactive immune system goes into an overdrive when it comes in contact with certain things. These things may be harmless in themselves. But the immune system tends to look at them as offenders and tries to react in a defensive manner. It tries to wash them off by producing excess mucous. The homeopathic medicines repair the immune system and the hyperactivity is corrected. Then the body reacts normally to the same things that used to cause the allergies.
