Allergic rhinitis, also known as allergic rhinitis, is a rhinitis caused by the body’s allergy to a certain substance, which can cause a series of allergic symptoms. It is an inflammation of the mucous membrane of the nasal cavity, which is characterized by congestion or edema. Patients often experience nasal congestion, runny nose, nasal itching, throat discomfort and cough. When inflammation occurs in the nose, the nasal cavity can secrete a large amount of nasal mucus, which can turn yellow due to infection, and can cause coughing when it flows through the throat, and can also flow out through the anterior nostril when the amount of nasal mucus is very large. The causes of allergic diseases are complex, and they often occur at the first “touch”. It is very distressing to see that it does not heal. In the face of this serious situation, the treatment of allergic diseases should take a rational and comprehensive program of symptomatic treatment combined with allopathic treatment. Characteristic immunotherapy is the only allopathic treatment for allergic diseases, and it is complementary to allopathic treatment to cure allergic diseases. Characteristic immunotherapy is highly safe and no serious adverse reactions have occurred so far. The method is convenient, not limited by time and place, and can be used safely at home or during travel. The administration is gentle and does not require injections, which is especially suitable for pediatric patients. After two months of treatment, all symptoms disappear, and then maintained for a period of time, the treatment effect can be maintained for several years, and some patients can even maintain lifelong, effectively stopping the development of allergic rhinitis to allergic asthma.
