This product is effective in treating allergic rhinitis, chronic rhinitis, sinusitis, pharyngitis, periodontitis, oral ulcer and tonsillitis. Is the product advantage two-way? 6? Nano-silver nasopharyngeal hydrogel sprayer: a major breakthrough in medical field in the history of nasopharyngitis treatment. The traditional methods of treating chronic rhinitis and pharyngitis have poor curative effect, and the treatment is extremely incomplete, which makes bacteria and viruses resistant to drugs, and nasopharyngitis recurs, which leads to the long-term treatment of the disease and makes the patients miserable and very painful. Because of its unique therapeutic mechanism, unique drug composition and powerful and thorough ability to kill pathogenic bacteria, nano-silver nasopharyngeal sprayer will not produce the next generation of drug resistance. At the same time, according to the structural characteristics of communication between nasal cavity and pharyngeal cavity, simultaneous treatment of nasopharynx can effectively prevent cross-infection, so nasopharyngitis can be cured fundamentally. 1, systemic diseases, comprehensive treatment of nasal cavity and pharyngeal cavity are interrelated, inflammation and pathological changes occur, bacteria and viruses will transfer and flow between them, resulting in cross-infection. It is one of the fundamental reasons that the inflammation of nasal cavity and pharyngeal cavity is stubborn and incurable for a long time to separate the inevitable connection between them and the treatment effect is extremely poor. Double visit? 6? As the latest nano-silver product in the world, its composition conforms to the process of human metabolism, and it is the safest, purest, most stable and most bactericidal nano-silver preparation in the world. It can be directly sprayed on the nasal cavity and throat to fully contact and completely kill pathogens. Treating nasopharynx at the same time, completely getting rid of the trouble of repeated cross-infection caused by single treatment or incomplete treatment is a major breakthrough in the treatment of nasopharyngitis. 2. Is green sterilization nontoxic? 6? 4 is a new generation of green, natural and drug-free non-antibiotic bactericide, which can kill a wide range of pathogens of viruses, bacteria and mucosal infections. More than 650 known viruses have been tested by Stanford University in the United States. All viruses can be effectively killed in a short time, and they are equally sensitive to antibiotic-resistant strains. Its safety even reaches the food-grade standard, and it has no irritation to nasal cavity and pharyngeal cavity, does not affect the growth of normal mucosal flora, has no toxic and side effects, has no drug resistance, and does not destroy the normal PH value of human body. 3, chronic diseases are not cured for a long time. Due to the defect of treatment concept and the limitation of treatment methods, small lesions are seriously ill and become stubborn and chronic diseases. Nano-silver nasopharynx sprayer adopts nano-technology, and the drug components are
