Abstract:
Lianhua Qingwen preparation （LHQW） is a Chinese traditional patent medicine approved by China Food and Drug Administration （CFDA）， and divided into two dosage forms， namely capsules and granules. Based on TCM theory， its therapeutic functions are contagion-clearing， detoxification， antipyretic， and lung-ventilating regulation， with influenza as its indication. In this paper， its pharmacological activities were reviewed. LHQW had a significant anti-virus effect characterized by a broad-spectrum pattern. It was reported that it not only possessed definitely suppressive effect on a series of influenza viruses， respiratory syncytial virus， coxsackie， enterovirus， herpes simplex virus，but also displayed a significant inhibitory effect on both the new corona pneumonia virus （SARS-CoV-2） and SARS coronavirus （SARS-CoV）. Studies showed that LHQW has obvious anti-inflammatory effects on a variety of inflammation models. It can significantly increase the delayed hypersensitivity of immunocompromised mice （caused by hydrocortisone） against 2， 4-dinitrofluorobenzene， and improve their cellular immune function. It can improve the phagocytosis function of peritoneal macrophages， the serum hemolysin antibody level and the humoral immune function of mice with a low immune function， with a immunomodulatory effect. In addition， LHQW has therapeutic effects on the symptoms induced by respiratory tract infections， such as fever， cough and phlegm， so as to block the vicious circle of multiple pathological links of the disease， and bring the advantages of multi-target， multi-link and multi-approach overall treatment of TCM into play.
