I love history, especially when scientist find new evidence that contradict the previous statements. Like now when they discoverd that tea is much older than thought to be. Researches recently found residues in a burial pit near tomb of Han dynasty emperor Liu Qi. It reveals that the plant used for tea was being transported along Silk Road route over 2,000 years ago.
The oldest written reference to tea is from 59BC. And the oldest physical remains ever discovered previously were hundreds of years younger than the new find – dating from the northern Song Dynasty. Researchers compared this tea to residues unearthed among burial artefacts at Gurgyam cemetery in Tibet, and dated to about the second or third century AD. This revealed that tea, which does not grow in Tibet, was already being transported from China to central Asia and the Tibetan Plateau several hundred years earlier than previously recorded.
