Nara Medical University (奈良県立医科大学, Nara Kenritsu Ika Daigaku) reported on November 27th, 2020 that their research confirms that green tea sold in the market can kill or make the virus harmless in their study.
The research is the first stage of the study, and they have not tested with the human body yet; however, adding COVID virus in green tea for one minute reduced their Infectious by 99%.
They said that the test results differ from a different brand of tea. The university is considering publicizing the brand name after contacting the tea manufactures.
The research was lead by Dr. Hisakazu Yano 矢野寿一.
The team used ten types of bottled green tea and black tea; they mixed the virus with tea and tested their Infectious over time.
The most effective tea was loose leaf black tea, and the virus lost 1/100 of Infectious power in one minute; after 10 minutes, it lost its Infectious by 1/1000.
Dr. Yano mentions that "there is a possibility of effectiveness in the human body since catechin's
effectiveness to influenza has already been proven in the human body by consuming tea."
Dr. Yano also mentions that tea's catechin attaches itself to protruding protein, which reduces the Infectious of influenza, and he hypothesizes that the same is happening with COVID19.
