Evidence of infused tea found in 12th century tombs

The discovery of green tea leaves in Chinese tombs may prove that infused tea was being served as far back as the 12th century, instead of only in modern times, as previously believed.

Zhang Yun, a researcher with Shaanxi Provincial Institute of Archeology, discovered the tea in 29 tombs in Lantian County. It was earlier believed that only boiled tea was used in the Middle Ages.
