But to our surprise, it was invented by accident. It wasnt brought to western world until 1610, but it was discovered 3,000 years earlier. An ancient Chinese legend says Shen Nong discovered the tea when he was boiling drinking water in the open air. Some leaves from a nearby bush fell into the water and remained there for some time.
