Desensitization therapy is standardized specific immunotherapy. Its main principle is to obtain the allergen type of the patient after detection, then prepare the allergen extract into allergen extract, and prepare preparations of different concentrations. Then, through repeated subcutaneous injection, sublingual administration and other administration routes, the patient is repeatedly contacted. At the beginning, the dose concentration should be given is smaller, and then the dose concentration is gradually increased until it is maintained to a certain dose and sufficient treatment course.
