Abstract

The invention provides an application of simiarenol in preparation of drugs for treatment of upper respiratory tract infection. Experiments prove that simiarenol has a certain inhibition effect on both respiratory tract infection related viruses and bacteria and also reduces the lung index, the TNF-alpha content, nasal mucosa inflammatory cell number and the nasopharyngeal lavage liquid colony number of mice with upper respiratory tract infection, and indicate that simiarenol has an obvious anti upper respiratory tract infection effect.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a use of sagodactyl alcohol. Background technique [0002] Upper respiratory tract infection, referred to as upper flu, is a general term for inflammation of the nasal cavity, pharynx, and throat respiratory mucosa, including the common cold, acute sinusitis, acute otitis media, etc. The clinical manifestations are fever, headache, nasal congestion, sore throat, cough, etc. It is characterized by nasal edema and pharyngeal mucosa congestion.
