Erythromycin ointment is not a treatment for rhinitis. The main role of erythromycin ointment is local anti-inflammatory, softening the blood vessels and accelerating the healing of the mucosa. The main purpose of erythromycin ointment is to reduce local inflammation, soften blood vessels and accelerate healing of the mucosa. Rhinitis can be divided into simple rhinitis, hypertrophic rhinitis, and allergic rhinitis. Simple rhinitis, usually secondary to an acute upper respiratory tract infection, causes bilateral nasal congestion in patients with alternating changes and no yellow discharge from the nasal cavity. In terms of treatment, symptomatic anti-inflammatory treatment is needed, while the nasal cavity can be gradually cured in about a week with the topical use of Daphnin nasal aerosol. Hypertrophic rhinitis, on the other hand, is caused by recurrent or prolonged attacks of simple rhinitis, which results in bilateral persistent nasal congestion with progressive aggravation. In terms of treatment, surgery is required, and partial excision of both inferior turbinates can be performed, which can be cured after surgery. Allergic rhinitis is caused by allergic reaction to certain substances in the nose after the body’s immunity and resistance are reduced. Patients will experience symptoms related to morning sneezing, runny nose, nasal congestion and so on. In terms of treatment, patients need to exercise and improve their immunity, while the nasal cavity needs to be controlled by using endosulfan or coleus topical to control the symptoms before it can be slowly cured.
