Coimbatore, Apr 17 () The UPASI Tea ResearchInstitute at Coonoor in Nilgiris district of Tamil Nadu isexploring the possibility of investigating the anti-viralproperty of Theaflavins-3, a compound abundantly found inblack tea and catechins from green tea for control ofCoronavirus.
The study is being undertaken in collaboration with TeaBoard of India through ICMR.
Researchers from Taiwan and China have found that ina laboratory study SARS Cov-2 could be inhibited by compoundsthat are abundant in teas, CL Shreedharan, Chairman, UPASI TeaCommittee, said in a statement here.
Numerous black tea polyphenols especially those ofTheaflavins-1, Theaflavins-2 and Theaflavins-3 were found toinhibit the SARS Cov-2 replication.
In black tea, Theaflavins-3 was the most abundant(1.05 per cent).
Results suggest that Theaflavins might be goodstarting point for the design of more active inhibitors forSARS-CoV-2 and these compounds are abundant in the extract ofblack tea produced from the seedling populations belonging toCamellia L SP as well as the cultivars developed by the UPASITea Research Institute, he said.
In another recent study, a research group fromIndonesia and Thailand studied the secondary metabolitessecreted by plants in tropical regions that can be developedas medicines.
They investigated a number of compounds for theirpotential to inhibit COVID-19.
Conclusion of the study was that along with severalcompounds catechin, and epicatechin-gallate sourced from Tea(Camellia sinensis) were also the most recommended compoundsthat may act as potential inhibitors of COVID-19.
The UPASI chairman said it was proved that drinkingthree to four cups of black tea in a day is associated withlower risk of myocardial infarction and reduced risk ofstroke.
According to him, it was also proved that drinkingblack tea, which has Theaflavins content, three times a dayhad a positive impact on reducing the degree of growth ofcancerous cells including breast cancer, skin cancer andprostrate cancer.
However, further research on clinical studies isrequired to prove the anti-viral property of tea againstCOVID-19, he added. NVM BNWELCOME BNWELCOME
