Recent research results show that the polyphenol catechin group extracted from green tea can inhibit the replication of coronavirus, strengthen the immune mechanism and improve acute lung injury. It can not only be used as a weapon to prevent virus transmission and mutation, but also can effectively alleviate the symptoms of COVID-19.
This study simulates the occurrence of pneumonia, lung injury, immune storm, and multiple organ failure in white mice caused by coronavirus, and found that white mice taking catechin group can increase the percentage of CD8+ T cells related to immunity and improve adaptive immunity, strengthen the autophagy mechanism and other functions to alleviate the symptoms.
