According to a new study by US scientists, green tea contains epigallocatechin gallate (EGCG)By preventing the new type of corona virus from attaching to cells, it can prevent severe cases of Covid-19.
However, published as a pre-print in the medical journal BioRxiv “Epigallocatechin Gallate from Green Tea Effectively Blocks Infection of SARS-CoV-2 and New Variants by Inhibiting Spike Binding to ACE2 ReceptorThe study named ”has not been reviewed by the referees yet.
PREVENTED VIRUS HITING VIRUS PROTE IN ACE2 RECEPTORS
The researchers stated that green tea consumed for many years in Asia has high anti-inflammatory and anti-oxidative properties that can help reduce the risk of developing severe Covid-19 symptoms. It was stated that the substance called epigallocatechin gallate (EGCG) in green tea prevents the spike protein of SARS-CoV-2, which causes corona virus, from attaching to angiotensin Converting Enzyme 2 (ACE2) receptors.
Scientists reported that ACE2 receptors function as a “lock” that opens the cell door to the corona virus. ACE2, an enzyme attached to the outer surface (cell membrane) of cells in the lungs, arteries, heart, kidneys and mucous and intestines, plays a role in lowering blood pressure, but these cells also cause the corona virus to enter the cells, causing the virus to progress in the body, especially the lungs.
ITS EFFECTS ON MUTATIONS IS ALSO EXAMINED
However, the research team has a single mutation K417N, E484K, N501Y, D614G and full set mutations of B.1.1.7, B.1.351 and B.1.42 with multiple modifications to examine the effect of green tea on emerging variations of the corona virus. Generated several pseudoviruses (artificial viruses) containing S proteins.
These pseudoviruses were then transfected into HEK293T-hACE2 cells in plasma cells from volunteers. It has been stated that epigallocatechin gallate (EGCG) in green tea provides protection in transfected cells.
The results showed that green tea, the original version of the virus, D614G, B.1.429 found in California, effectively prevented the B.1.351-borne infection that occurred in South Africa. The researchers also suggested that EGCG may also be partially protective against B.1.17, known as the British variant.
On the other hand, scientists have stated that EGCG is the strongest inhibitor for viral infection. EGCG accounts for over 50 percent of the catechins found in green tea beverages.
The authors of the study said, “Our results show that green tea is safe and can be an effective preventive measure that can help prevent Covid-19 infection.”
