Problems solved by technology

[0005] Since the 1990s, researchers have discovered many new antiviral drugs. At present, more than 20 antiviral drugs have been used clinically, but their exact efficacy is still controversial, and antiviral chemically synthesized drugs have long been used. After application, the virus easily develops drug resistance to it, which has become a thorny problem in the clinical treatment of viral diseases
Modern pharmacology shows that Patchouli has anti-pathogenic microorganisms, anti-inflammatory, antipyretic, and analgesic effects. The material basis is not yet clear and there is no report of its anti-influenza virus effect in vivo

Description

technical field [0001] The present invention relates to the new application of Huoxiang oil, in particular to the application of Huoxiang oil in preparing antiviral medicine. Background technique [0002] Infectious diseases caused by viruses have been a serious threat to human life and health. According to statistics, more than 80% of infectious diseases are caused by viruses. Viral diseases have been involved in various fields of clinical medicine. At present, viruses and the diseases caused by them have become the focus of many disciplines. The most common viral infectious diseases are those caused by respiratory viruses and enteroviruses. [0003] Respiratory viruses are a large class of viruses that can invade the respiratory tract and cause local lesions of the respiratory tract, or viruses that only use the respiratory tract as an invasion portal to cause lesions of respiratory tract tissues and organs. They are the main pathogens that cause acute respiratory infecti...
