The latest domestic research has found that catechins can inhibit the replication of the new coronavirus, strengthen the immune mechanism, reduce the damage of the virus to the lungs, and effectively alleviate the symptoms of new coronary pneumonia. It is recommended to take 2.5 grams of catechins per day to prevent new coronary pneumonia. pneumonia.
The research team of Taiwan Normal University recently published the latest research results of inhibiting the activity of the new coronavirus. The research confirmed that the polyphenol catechin group extracted from green tea, this result has been published in the internationally renowned journal "Antioxidants" ( Antioxidants).
Taiwan Normal University School of Life Sciences Founding Dean and Distinguished Professor Zheng Jianting pointed out that the study found that patients infected with new coronary pneumonia will tend to upregulate the inflammatory signal of TLR-4 mediators, similar to the sepsis pathway that bacteria cause multiple organ failure.
The research team further used the lipopolysaccharide-induced model to simulate the symptoms such as pneumonia, lung injury, immune storm and multiple organ failure caused by coronavirus in white mice. It was found that taking catechin group can increase the immune-related CD8+ of white mice The percentage of T cells, improve adaptive immunity, strengthen autophagy mechanism, etc., slow down the symptoms of new coronary pneumonia.
In addition, the data of human catechin group also shows that the immune function-related CD8+ T cells can maintain a peak of 4 to 5 hours, which can be divided into 1.25 grams each time, 2 times, or 0.83 grams each time. Three times, plasma catechin concentrations of 239 μg/ml and 359 μg/ml were obtained, respectively.
Zheng Jianting explained that catechins can inhibit the "coronavirus replicase" that promotes virus replication and infection, which can effectively prevent the virus from continuing to replicate and mutate. The tea is a health food, and it has been used in experiments for many times. The results show that the effect of inhibiting the new coronavirus is good, and it is suitable as an adjuvant therapeutic food against the new coronavirus.
Yang Zhiqing, the first author of the paper and the technical supervisor of the Ministry of Health and Welfare, believes that it is during the epidemic period of the new crown pneumonia. There are also confirmed cases in foreign countries who have received 2 doses of the new crown vaccine. Research has confirmed that taking catechins can enhance immunity and resistance, effective against the new coronavirus.
One of the co-authors, Wu Zhangzhe, director of the Department of Food Science of Taiwan Ocean University, also said that early studies have confirmed that catechins have anti-influenza virus infection; this study also found that catechins have the ability to inhibit the replication of the new coronavirus It can also reduce the inflammation of the lungs caused by the virus and reduce the damage to the lungs by the virus.
"Health 2.0" reminds you
In response to the new crown pneumonia epidemic, the CDC continues to strengthen epidemic monitoring and border control measures, and wear a mask as instructed to seek medical treatment as soon as possible, and actively inform the doctor of travel history and contact history, so as to facilitate timely Diagnosis and notification.
