Second: antigenic substances: substances that stimulate the body to produce allergies are called allergens, such as ingestive allergens: allergens that enter the body from the digestive tract and cause allergic rhinitis. This is also the cause of allergic rhinitis.

Allergic rhinitis, or allergic rhinitis, refers to the non infectious inflammatory disease of nasal mucosa, which is mainly caused by the release of IgE mediated mediators (mainly histamine) and involves a variety of immunocompetent cells and cytokines after the contact of atopic individuals with allergens. There are three necessary conditions for its occurrence: specific antigen is the substance that causes the body's immune reaction; atopic individual is the so-called individual difference and allergic constitution; specific antigen meets atopic individual. Allergic rhinitis is a global health problem, which can lead to many diseases and labor loss.
