Considered to be a sole component of the Cuban biotechnology boom, this anti-viral drug called Interferon Alfa-2B is produced in China, by Cuban-Chinese joint venture ChangHeber.
Cuba has already sent an emergency assembly of doctors to fight the coronavirus in Italy, while already working alongside 37 countries worldwide that have confirmed cases of COVID-19.
The component L-theanine (found in Green Tea) is broken down in the liver to create ethylamine, a molecule that initiates the response of an immune system element called the gamma-delta T cell. The T cells in the blood prompt the release of interferon, a key part of the body's chemical defense against many types of bacteria, viral, fungal and parasitic infections.
An experiment using human volunteers, showed that immune system blood cells from tea drinkers responded five times faster than the others.
