You know the beautiful reddish amber color that we often look for in black puer? It may be more than just beautiful, it may help protect you from coronaviruses. According to this 2005 Taiwan study, tannic acid and theaflavin in puer tea and traditional (baked) black tea created from enzymatic oxidation of tea leaves inhibited the reproduction of the deadly SARS coronavirus. Theaflavin helps to stop SARS coronavirus replication by inhibiting a key reproductive enzyme called 3CLpro. Theaflavins are antioxidant polyphenols that are reddish in color. However, unlike traditional black tea, puer tea is never baked so the beneficial microbial aging and enzymatic oxidation of the leaves continues for years. This is why aged puer is darker in color than black tea.<\/p>\n\n\n\n
\nA study about tea theaflavins and the coronavirus in pigs conducted by the Texas A&M University College of Veterinary Medicine found that:\nAn in vitro study of theaflavins extracted from black tea to neutralize bovine rotavirus and bovine coronavirus infections<\/a>\n We do not know if puer tea and black tea are effective against COVID-19. But if they protect against SARS, which was a much more lethal coronavirus (10 percent mortality rate vs less than 1% for COVID-19), and if COVID-19 replication is similar to that of the SARS coronavirus, they may. For most people there is little risk in drinking tea, and if this study is correct, it may provide a life-saving benefit. Puer tea is famous for improving digestion, and is used by acupuncturists for treating dysentery. A recent study found that digestive issues and diarrhea may be the first signs of COVID-19.<\/p>\n\n\n\n Digestive Issues ‘could be the first sign of the disease’<\/a><\/p>\n\n\n\n Puer tea also may lower blood sugar and blood pressure, and contains anti-inflammatories such as theophylline and GABA which may assist some people with breathing issues. Elderly people with diabetes, heart conditions and high blood pressure are at higher risk from COVID-19. We have heard from acupuncturist who cited an internal memo from a top US Hospital that Japanese doctors treating COVD-19 recommended drinking liquid every 15 minutes to wash any virus into the stomach, preventing it from entering the lungs. Your stomach acid will kill the virus.<\/p>\n\n\n\n SARS puer tea, black tea study abstract<\/strong><\/a><\/p>\n\n\n\n SARS puer tea, black tea full study<\/strong><\/a><\/p>\n\n\n\n For reference:<\/p>\n\n\n\n
